OSHA requires every job site to keep first aid supplies on hand, readily accessible to every employee, in a container that matches the hazards of the work. In practice that means a kit graded Basic, Class A or Class B under the ANSI Z308.1 standard, sized to the number of people on site, and packed with bleeding control supplies rather than a wall of adhesive bandages. The best first aid kits for job sites below are the ones that hold up to that standard in dust, rain, sun and a truck bed.
Our team compared eleven kits that contractors, truck fleets and site managers actually buy, over several weeks: metal cases against plastic, wall-mounted cabinets against grab-and-go bags, ten-person kits against cabinets rated for 250. We weighted four things. Does it meet the class your hazard level demands, does the container survive a job site, can a bleeding injury be controlled with what is inside, and can you refill it without hunting for a supplier.
One thing the forums get right over and over. A long-running thread on r/Construction asking about job-site med kits drew more than 280 comments, and the near-universal conclusion was that the compliance kit is the floor, not the finish. Serious crews bolt a personal trauma pouch onto the belt or keep a second kit in the truck. If your trade sees heavy equipment, blades or hot work, read our trauma kit picks before you settle.
Everything below is for general and product comparison purposes. Site-specific medical response, bloodborne pathogen exposure plans and crew training are decisions for your own competent person, not a web page.

1. First Aid Only 9302-25M 25-Person Contractor Kit: Our Pick for Most Job Sites
First Aid Only 9302-25M 25-Person Contractor’s First Aid Kit for Home Renovation, Job Sites, and Construction Vehicles, 178 Pieces, White
178 pieces
25-person capacity
Wall-mountable metal case
1.38 pounds
+ The Good
- Metal case takes real abuse and mounts to a wall or trailer stud
- 178 pieces covers cuts
- burns
- scrapes and tool injuries
- Easy-release latch opens one-handed
- Light enough at 1.38 pounds to carry to an injured worker
- The Bad
- No tourniquet or mouth-to-mouth barrier in the standard contents
- Metal adds weight compared with a plastic kit of the same size
This is the kit most of our recommendations come back to. It has been on the market for well over a decade and carries 6,796 reviews at a 4.7 average, which tells you something important about long-term failure. Metal cases in job site use tend to survive. Plastic hinges, by contrast, go brittle in sun and snap.
At 178 pieces and a stated 25-person capacity, it fits the crew that defines most residential and light commercial work. A framing crew, a small renovation outfit or a single owner-operator running one truck can all be served by one of these. If you are the only person on site, this is already more than you need and it will live in the cab for years.
The contents are the classic contractor mix: adhesive fabric and plastic bandages, antibiotic ointments, BZK antiseptic towelettes, burn cream packets, gauze rolls and pads, gloves, scissors and tweezers. That covers the injuries that actually happen with hand tools: abrasions, shallow lacerations, splinters, minor burns and the staple-through-finger case that ends most renovation jobs.
Two details matter more than the piece count. The wall mounting holes mean the case is a fixed station rather than a thing that slides around a truck bed, and the carry handle plus easy-release latch mean someone can grab it and be at the injury in under a minute. On a site where EMS is twenty minutes out, that minute is the whole point.
Is a 25-person rating enough for your site?
Count everyone who is on site on a normal day, not just your own crew, because a sub working under your direction still needs access. Fifteen to thirty people across one area, this is the right kit. Sixty people, or two areas on opposite ends of a slab, you need a second one and a larger tier.
Also worth knowing: this listing does not include a tourniquet or a CPR pocket mask. For most trades that is fine because a mounted Class A kit is a response-time asset, not a trauma asset. For anything involving blades, saws, rebar or heavy equipment, pair it with a personal trauma pouch.
What holds it back on a rough site
Metal is heavier than plastic, so this is not the kit you toss in a toolbox and forget. It wants a wall, a truck bulkhead or a shelf. The second limitation is interior layout, with some owners noting the compartments are less flexible than a large cabinet’s tilting shelves when you are trying to see the whole inventory at once.
Neither issue matters much once you mount it, because the inventory question then becomes a monthly sweep rather than a guess. If you want to equip a shop as well as a site, our broader professional first aid kit roundup covers the facility side.
2. Be Smart Get Prepared 326 Pc 100-Person Kit: Best Value for Large Crews
Be Smart Get Prepared 326 Pc OSHA ANSI First Aid Red Hard Case 100 People
326 pieces
100-person capacity
Impact-resistant plastic
3.2 pounds
+ The Good
- 326 pieces covering up to 100 people
- Two layers with tilting shelves for fast restocking
- Slide latches open quickly one-handed
- Refill order form included in the case
- The Bad
- Bulky 13 x 12 x 4 inch footprint for a vehicle
- Plastic housing is less protective than metal in a rough trailer
When you size a kit to the number of people rather than the number of drawers in a truck, the value case changes completely. This one holds 326 pieces and is rated for 100 people, with 7,194 reviews at 4.7. For a residential development, a commercial fit-out or a multi-trade site, that is a single kit covering the whole crew.
The interior is the part we like most. Two separate layers with tilting shelves means you can see the full inventory when you open it instead of digging through a bin, and the small items ride on the upper shelf rather than falling behind larger ones. That layout is a genuine restocking advantage, because a monthly inspection that takes seconds is one you will actually perform.
Buyers consistently single out two things beyond the piece count: the organisation, and the refill order form that is included in the case. That form matters more than it sounds. Replacement supplies for commodity kits are the least interesting part of any supply chain until you need them at 6pm on a Friday, and having the part number in the case removes the whole problem.
The case is described as high density and impact resistant, with slide latches rather than a hinged door that can spring open in a truck bed. It folds flat or mounts on a wall, so the same unit works as a facility station and packs down for transport when the phase changes.
When a 100-person tier is the right call
Reach for this when your headcount is high or your workers rotate through the same area, because consumables disappear with rotation rather than with headcount. A crew of 30 that turns over every fortnight will burn through supplies faster than a crew of 60 that stays put, and the rated capacity is a guide rather than a promise.
It is also the right answer for a general contractor who is the responsible party for a shared site. When you are providing the common kit for multiple subcontractors, you want the capacity that will not need replacing every week, which is the other reason to size up.
Where the bulk shows up
At 13 by 12 by 4 inches and 3.2 pounds, this is not a portable kit. It is a station. Trying to run it in a service van means it lives in the cab, where sun through the windshield is the main enemy of anything adhesive in the case.
The second limitation is material. Plastic is entirely adequate for a dry, indoor or sheltered station, and it is a real step down from metal if the case is going to be kicked, dropped or left in a dusty trailer. If your site is genuinely rough, buy a metal case instead.
3. 24/7 First Aid 336 Piece 100-Person Kit: Best for Visible Inventory
24/7 First Aid OSHA Compliant First aid Kit, All-Purpose 100-Person Emergency First Aid Kit for Business, Home, and Car in Plastic Case with Easy-Slide Latches, 336 Pieces
336 pieces
100-person capacity
Clear cover
3.02 pounds
+ The Good
- Clear cover shows a depleted shelf without opening anything
- Holds 336 pieces in a shallow 3.25 inch depth
- Individual compartments keep supplies sorted
- Category sales rank of number 11 in first aid kits
- The Bad
- Single-layer packing means some items sit under others
- Case colour can vary between shipments
The 24/7 kit earns its place with one design decision: the cover is clear. On a site where the kit sits in a trailer or a hallway and gets used by whoever is closest, being able to see that the gauze shelf is empty from three feet away is a genuine safety improvement rather than a cosmetic one. At 4.8 stars across 1,712 reviews it also holds the strongest category sales rank of any kit in this group, at number 11 in first aid kits.
At 336 pieces for up to 100 people, this carries the same crew coverage as the Be Smart kit with a different tradeoff. The 3.25 inch depth is shallow, so everything packs in a single layer. That single layer works well for finding a specific item fast. It works badly for stacking bulky dressings over small ones.
Contents follow the OSHA pattern: adhesive fabric and plastic bandages, antibiotic ointments, BZK antiseptic towelettes, burn cream packets, gauze rolls and pads, gloves, scissors and tweezers. The case mounts on a wall with easy slide latches, and 3.02 pounds is light enough that one person can lift it off the mount and bring it to a worker on a lower level.
Our read is that the clear cover changes inspection behaviour more than any other feature on this list, because a monthly sweep becomes a glance instead of a case opening and a divider rebuild. That is the difference between a check that gets done and one that gets deferred.
Clear lid versus tilting shelves: which inspection style suits your crew?
Choose the clear lid when the kit is opened by many different people and nobody owns the inventory. Choose tilting shelves when one person does the monthly check and wants everything presented at once. Both work; they just fail differently. A clear-lid kit hides what sits under what, and a shelf kit that gets left standing open collects dust until the next inspection.
This is a good fit for offices with tradespeople coming and going, mixed-use facilities and small sites where the person responsible for the kit changes. For a shop where a single owner does the checks, our emergency kit guide covers the smaller formats in more detail.
Watch for what the single layer hides
The honest weakness is depth. Anything that sits at the bottom of a compartment is functionally invisible during a quick check, so this format rewards a rule: keep small items on top and bulky dressings at the back, and never restock by dumping a fresh refill bag on top of a half-empty one.
Reviewers also note the case colour can differ between shipments, which matters if you have multiple identical kits on site and are colour-coding them. Not a defect, just worth knowing before you order four of them.
4. M2 BASICS 350 Piece Wall-Mount Kit: Best for Shops and Fleet Spaces
M2 BASICS 350 Piece Professional Wall-Mount First Aid Kit, Business, Home
350 pieces
Dual swing-out layers
3 pounds
Wall-mount hard case
+ The Good
- Largest supply count among the plastic-cased kits here
- Dual swing-out layers protect and display contents
- Suited to shops
- warehouses
- fleet vehicles and job sites
- Rated 4.7 stars across 4472 reviews
- The Bad
- Interior swing-out shelf hinges are thin and stiff
- Outer case and latch are adequate rather than heavy duty
At 350 pieces this is the highest supply count among the kits here that are not full cabinets, and the dual swing-out layer design is the reason we could put it in a roundup for job sites at all. The shelves fold out and hold the supplies visible and protected, which is closer to a mobile cabinet than a box of loose dressings. Owners in small shops, farm shops and offices rate it highly for completeness.
It is the natural pick for a mixed facility. A contractor with a shop, a warehouse and trucks is buying one kit that works in all three, and the wall-mount format means the shop copy stays put while the vehicle copy travels. The 13 by 11 by 4 inch footprint and 3 pound weight are typical of a mounted unit.
Contents cover the commercial base: bandages, gauze pads, antiseptic wipes, dressings, wraps, gloves and tools addressing cuts, scrapes, burns and minor injuries. That is a general injury profile rather than a trades profile, which is the one thing to keep in mind below.
The most repeated complaint across reviews is specific and worth repeating here: the interior swing-out compartments have thin, stiff hinges, and some items are hard to reach when the shelves are loaded. This is a real usability issue in gloves, and it is the kind of detail a spec sheet will never tell you.
Is 350 pieces overkill for a job site?
It depends entirely on how many people touch it. For a 10-person framing crew, 350 pieces is generous and the extras are dead weight in a truck. For a shop or warehouse where a hundred people pass through and staff treat their own paper cuts, high piece counts get consumed quickly and the real question is refill lead time, not initial capacity.
Check the refill question before you commit. Commodity kits are easy to refill by part number; kits assembled from loose components are not. If you can identify a matching refill for the exact model, the initial size matters far less than the availability of the restock.
How the stiff hinges play out in daily use
Expect to open and close the shelves repeatedly during a busy week, and expect them to need a firm hand. They hold up in normal service according to owners, but they are not smooth, and gloves plus grit is the combination that tests them. A wipe-down of the hinge line during your monthly check keeps the grit out.
The outer case and latch are described as adequate rather than heavy duty, so this is a wall unit first. If your kit is going into a truck bed or a shed that gets kicked, look at a metal case instead.
5. First Aid Only 225-AN 50-Person Kit: Best for Small Crews That Want Eye Wash
First Aid Only 225-AN 50-Person OSHA-Compliant First Aid Kit, Emergency First Aid Kit for Office, Home, Car, and Worksites, 195 Pieces
195 pieces
50-person capacity
Plastic case with dividers
4 oz eye wash
+ The Good
- Includes a 4 oz eye wash and a 40 inch triangular sling
- Compact 10.75 x 3 x 11 inch case with dividers
- Mounting holes for a vertical surface
- Rated 4.7 stars from 595 reviews
- The Bad
- Plastic case develops static that attracts dust and hair
- Some supplies are unnecessary for the intended use
There is a reason this kit has been in the First Aid Only line for years. For a crew between 25 and 50 people it hits the coverage tier that most residential and light commercial work actually needs, and it pairs a 4 ounce eye wash with a 40 inch triangular sling, a combination that is rare in this group. Eye wash is not decoration on a site with grinding, welding and overhead work.
At 195 pieces with individual compartments and mounting holes for a vertical surface, it works as a fixed station that a small crew can self-manage. Owners frequently buy it to consolidate loose supplies from a truck, a shop and a job trailer into one auditable box.
Contents match the standard OSHA contractor pattern: adhesive fabric and plastic bandages, antibiotic ointments, BZK antiseptic towelettes, gauze rolls and pads, gloves, scissors, tweezers, exam quality vinyl gloves and the eye wash. It is a solid, unfussy box that does what the compliance rule asks without pretending to be more than that.
One documentation note. The catalogue weight field for this item is inconsistent, so treat the dimensional footprint as reliable and the weight as something to confirm for yourself if you plan to carry it far from a vehicle rather than mount it.
Does your crew need a 50-person tier or a 25-person one?
Work it out from simultaneous presence, not from your payroll. A six-person carpentry crew with a 30-person GC on site on the same day is a 36-person situation, and a 25-person kit will be stressed. A solo owner-operator with occasional laborers is comfortably a 10-to-25 person situation and does not need this size.
Consider the eye wash and sling as the deciding features rather than the piece count. If anyone on site grinds, cuts, welds or handles chemicals, the eye wash earns its place. If you only need to cover a punch-card office with two people in it, this is larger than you need and a smaller kit is the honest answer.
The static problem and how to live with it
The most detailed recurring criticism is that the plastic case builds static and attracts dust, hair and lint, which is exactly what you do not want settling on open sterile packaging. In a dusty site that is a fair complaint, and it has a simple mitigation: keep the case closed, and wipe the interior and the seals during your monthly inspection.
Some buyers also note the packing includes items they will never touch, which adds bulk without adding capability. Judge the kit on what it covers, not on what is in the box, or you will be disappointed by perfectly good supplies.
6. ProHeal 50-Person Type III Class A Kit: Best for Compact Carry
50 Person OSHA Compliant First Aid Kit for Businesses, Vehicles, Trucks, Construction Site – Type III, ANSI Class A Emergency Kit – 197 Piece Essential First Aid Supplies
197 pieces
Type III Class A listing
9.76 inch square case
1.65 pounds
+ The Good
- Square footprint works on a wall or inside a cab
- Dual latches and a carry handle for fast access
- Available in 10
- 20
- 50 and 100 person variants
- 1.65 pounds is light for its coverage
- The Bad
- Contents are packed tight so the case feels crammed
- Plastic shell is not heavy duty next to a metal kit
Its 9.76 by 9.76 by 3.15 inch case weighs 1.65 pounds, and that footprint is the entire argument for this kit. It is the one to buy when the same kit has to be a wall station on Monday and a truck kit on Tuesday, because the wall mounting tabs and the carry handle are both standard rather than an accessory.
Buyers in commercial trucks, warehouses and small businesses say it ticks the required-compliance box with everything needed, and the 10, 20, 50 and 100 person variants in the same line mean a multi-site company can standardise on one product family and still size each location correctly. That consistency is worth more on a paperwork audit than any individual feature.
At 197 pieces, the supply mix is a standard Class A profile: gauzes, bandages, burn cream, cotton applicators, gloves, alcohol prep pads, triple antibiotic cream and eye wash. The case includes two latches, a comfortable handle and wall mounting tabs for horizontal or vertical surfaces, plus an instruction manual and guide. Usable indoors and outdoors, per the listing.
On the class rating itself, be precise about what the manufacturer claims. This listing describes the kit as Type III, ANSI Class A and compliant with OSHA 1910.151. Verify the current standard revision yourself against your compliance documentation rather than relying on a retail label, because the ANSI revision year matters on a formal submittal.
Which trades should buy this one?
Single-trades operators, service electricians, HVAC techs, plumbing crews and anyone running one van. A service van is a workplace under OSHA rules, and having a Class A box that mounts and un-mounts means the same compliance evidence covers both the vehicle and the job. Multi-person sites with a fixed office should buy a bigger mounted unit instead.
It also suits anyone who has been treating their kit as a compliance box in a trailer and wants a real response asset instead. At 1.65 pounds you can carry it to a basement, a roof deck or the far end of a site without an argument.
What to watch on a tight-packed case
The packing is tight, and reviewers note it can feel crammed. A tight pack is not a defect, but it means the bottom of a compartment is the first thing to be overlooked during a restock, and it means the last items in a refill pouch are the ones to check first.
The shell is thin plastic, so treat this as a portable kit rather than a mounted fixture in a rough shed. A 4.6 average across 385 reviews is solid rather than exceptional, and the most common note is that it runs smaller than it looks. Measure your shelf or cab before you commit to four of them.
7. First Aid Only 90671 50-Person ANSI B+ Kit: Best for High-Hazard Trades
First Aid Only 90671 50-Person ANSI B+ Contractor’s Emergency First Aid Kit for Home Renovation, Job Sites, and Construction Vehicles, 254 Pieces White
254 pieces
Ansi B+ rating
Metal case
4 pounds
+ The Good
- One of the kits in the group rated ANSI B+ rather than Class A
- Weather resistant metal case for trucks and sites
- Includes a CPR mask plus a tourniquet and padded splint
- Owners use it for OSHA training and crew briefings
- The Bad
- Bulky and heavy next to plastic kits of similar capacity
- Metal case can arrive dented from packing
This is the one kit here that answers the forum complaint about trauma-capable gear being missing from standard first aid kits. It carries a CPR mask with a one-way valve, a tourniquet, a padded splint, sunscreen packets and hand sanitizer packets alongside 254 pieces of standard supply. Owners report using the printed contents to train workers on what is actually in the box, which solves a problem the standard kits never address.
Its ANSI B+ rating puts it a class above the Class A kits in this roundup, and the review base is small at 40 ratings averaging 4.7 with nothing below four stars. Read that as a consistent, well-liked niche product rather than a widely tested mass-market item. For a 50-person high-hazard crew that consistency is worth more than raw volume.
The metal case is described as weather resistant and built for work trucks and job sites, measuring 13.88 by 9 by 3 inches at 4 pounds. At that weight it is a wall or bulkhead unit, not a grab-and-go pouch, but the carry handle and easy-release latches mean it can still be transported to an injured worker when needed.
What matters most here is that the tourniquet and pocket mask are in the box rather than in a separate bag someone might forget. On a demolition, excavation or blade-exposed crew, the difference between reaching for a tourniquet on a shelf and reaching for one in a truck is measured in minutes.
Which trades should choose B+?
Demolition, excavation, concrete cutting, forestry and tree service, scaffolding and any operation where a serious bleed is plausible from a single incident. These are the trades where a Class A kit is technically defensible but practically thin, and where a personal IFAK becomes a reasonable expectation rather than a fringe choice.
Owners mention using the kit contents to keep crews current on OSHA requirements and to run training. That is a real advantage: a kit with a visible tourniquet and mask is a teaching aid that a box of adhesive bandages is not.
Weight and the dented-arrival problem
At 4 pounds this is the heavier metal option in the group, and both the weight and the station format work for a fixed wall position but are awkward for anything you carry up a ladder or across a roof, so pair it with a personal trauma pouch rather than expecting the mounted box to be the whole answer.
The recurring complaint in reviews is that the metal case can arrive dented from packing. Owners confirm it still latches and seals, but inspect the case on arrival and photograph the packaging before you open it. For our wider look at hemorrhage control kit contents, see the trauma first aid kit roundup.
8. Rapid Care 4 Shelf Class A+ Cabinet: Best for Large Projects
Rapid Care First Aid 80099 4 Shelf All Purpose First Aid Kit Cabinet, Class A+, Exceeds OSHA/ANSI Z308.1 2015, Wall Mountable
Over 1010 pieces
Steel cabinet
Serves up to 250 people
16 pounds
+ The Good
- Serves up to 250 people from one cabinet
- Boxed and color-coded components for fast identification
- Wall mounted first aid sign included
- Many shelf and ANSI year variants to match a submittal
- The Bad
- Bulkiest unit in the roundup at 16 pounds
- Bulk cabinet format is excessive for a single vehicle or small crew
Everything else in this roundup fits on a shelf or in a truck bed. This is a station you build into the project, and for a large commercial or infrastructure job it is the right scale: over 1,010 boxed, color-coded pieces serving up to 250 people, in a wall-mountable steel cabinet that comes with a first aid sign.
The color-coding is the underrated feature. When a wall cabinet holds this many supplies, the person opening it under stress needs to find a specific item in seconds, and boxed color-coded components turn a search into a grab. Reviewers consistently name the organisation and the A+ class as the reasons to buy, offset by the weight.
The cabinet measures 5.75 by 15.5 by 22.75 inches and weighs 16 pounds, with a built-in handle for transport. It is rated to exceed ANSI Z308.1 2015 and OSHA guidelines, and it is sold in two, three and four shelf configurations across several standard revisions, which matters when a general contractor requires a submittal against a named standard year.
It is also rated for offices, warehouses, construction job sites and restaurants, so it doubles as the facility cabinet for a site office or a plant room. The wall-mounted sign is a small compliance touch that inspectors notice.
When a 250-person cabinet is the right scale
Large commercial builds, infrastructure and road projects, apartment developments, industrial facilities and any site where the general contractor is providing shared first aid coverage for many subcontractors at once. At that scale, a per-trade kit model breaks down and a central cabinet with a scheduled check is the only system that holds.
Be honest about the ratio though. One cabinet does not remove the multi-area accessibility requirement. If your site is spread across a slab and a basement, each separate work area still needs coverage, and a 250-person cabinet is the starting point for a populous site rather than the answer to a spread-out one.
The weight and the submittal question
At 16 pounds, this is not portable and should never be carried up a ladder or down a ladder. It wants a mounting position at ground or low level, in a central and unobstructed location, with a second kit on a vehicle for anything that happens away from it.
The 4.6 average across 270 reviews is solid, and the one consistent drawback is simply the bulk. Check the standard revision your documentation references before ordering, because this cabinet is specified against the 2015 revision and a project written to a newer revision may need a different listing. Our comparison of professional grade kits covers the smaller facility options.
9. BrightCare Wall-Mount and Portable Cabinet: Best for Mobile Crews
Large First Aid Kit Cabinet, Wall Mountable & Portable, OSHA Compliant
Wall mount and portable
12.83 by 11.61 by 4.02 inches
3.26 pounds
Mounting hardware included
+ The Good
- Removes from the wall and carries to the injured person
- Large green first aid panel is easy to spot
- Mounting hardware included in the box
- Very complete supply mix for minor to medium injuries
- The Bad
- Interior shelves are cheap and do not tilt as advertised
- Bottom front shelf can arrive loose
- Would benefit from more adhesive bandages
This solves a specific and underrated problem: the mounted box that stays on the wall while the injury happens three floors away. At 3.26 pounds with a wall mount and included hardware, the same unit serves as a facility cabinet and as a response kit you unhook and carry. At 4.8 stars across 62 reviews, owners including churches, small businesses and busy households describe it as very complete and easy to spot.
Supplies are the standard commercial mix: bandages, gauze, dressings, tape, gloves, scissors, prep pads, triangular bandages and CPR masks. The CPR masks are worth calling out, because mouth-to-mouth barrier protection is a bloodborne pathogen requirement and many comparable kits in this roundup omit it.
Reviewers single out the large green front panel, which is a legibility feature rather than decoration. On a site where several people have never seen the kit, a case they can identify from across a floor is a kit they will actually use. A plain grey box behind a stack of conduit is functionally invisible.
At 12.83 by 11.61 by 4.02 inches it is a mid-size cabinet, deep enough to layer supplies rather than pack them flat, and light enough that one person can lift it while supporting an injured worker with the other arm.
Wall-mounted or portable: which format do you actually need?
Wall-mounted if the site has a central, fixed, high-traffic location and the risk is in that area. Portable if your work is scattered, if the injury is likely away from a fixed point, or if you are outfitting a vehicle. This cabinet is the rare one that does both without being a compromise, which is why it earns a place here.
Consider a wall mount plus a separate vehicle kit if you have a large site. A mounted case that gets carried off its wall and then stays in a truck is a kit that is no longer accessible to anyone else, which quietly breaks your compliance position.
Check the shelves before you mount it
The most detailed review in this set flags that the interior shelves are cheap-feeling and do not tilt forward as the listing suggests, and that the bottom front shelf can arrive loose. The practical instruction from that owner is worth repeating: open the box flat, confirm the shelves are seated and the contents are not floating free, and only then carry it upright.
Several reviewers also asked for more adhesive bandages in the mix, which is a fair criticism of any kit that leans toward dressings and prep pads. The 4.8 average comes from a small 62-review base, so treat it as a well-regarded option rather than a proven standard.
10. MFASCO DOT Class A Vehicle Kit: Best for Commercial Vehicles
MFASCO Vehicle First Aid Kit – DOT/ANSI/OSHA Class A Compliant – Metal Box
115 pieces
Class A compliant
Sealed metal box
2.84 pounds
+ The Good
- DOT
- ANSI and OSHA Class A compliant for commercial vehicles
- Waterproof seal protects supplies in transit
- Hanging brackets mount it out of the way
- Compact enough for a glove compartment or drawer
- The Bad
- Plain appearance
- Contents sit in a cheap single-use plastic bag separator
- Mostly plastic rather than fabric adhesive bandages
A service van or a commercial truck is a workplace, and this kit is built for that frame. At 115 pieces it is DOT, ANSI and OSHA Class A compliant, assembled in the USA, and specified for commercial vehicles, semi-trucks, work vans and remote job sites. Reviewers report buying it specifically because it satisfied their vehicle compliance obligation.
The feature that matters on a vehicle is the waterproof seal. Other kits in this roundup are described as water resistant at best, and only this one carries a stated seal. A sealed metal box changes the failure mode from ruined supplies after a wet site or a rained-on open bed to contents that survive the trip.
Hanging brackets let it mount on a bulkhead or behind a seat rather than sliding around on every turn, and the 9.5 by 6.75 by 2.75 inch footprint at 2.84 pounds fits a glove compartment, a drawer or a backpack.
Contents are the standard contractor mix of 115 pieces: bandages, gauze, antiseptic wipes and tweezers. That is fewer pieces than the site kits here, and that is the correct trade. A vehicle kit is not sized to a crew, it is sized to one responder driving to the scene.
DOT requirement or OSHA requirement?
If you operate a commercial motor vehicle in interstate commerce, the Department of Transportation carries its own first aid kit requirement for the vehicle, and DOT compliance is a separate obligation from your OSHA obligations as an employer. A kit that satisfies both, as this one claims to, removes the most common source of confusion for owner-operators.
Check what your own carrier and state rules ask for rather than assuming a listing is sufficient. Our general guidance on emergency kit contents covers the categories a vehicle should carry.
Metal build quality against a plastic tub
The metal box and seal are the reason to buy this, and reviewers rate the case and contents as higher quality than typical kits. The two criticisms are cosmetic but worth naming: the styling is plain, and the contents sit in a single-use plastic bag separator that some buyers discard immediately and replace with their own organisation.
At 4.8 stars across 94 reviews, this is a fleet and owner-operator product rather than a crew station, and it is also the only kit in the group specified with a seal.
11. EVERLIT 185 Piece Metal Contractor Kit: A 4.9-Rated Metal Alternative
EVERLIT 185 Pcs Metal First Aid Kit for Contractors, Construction Site, OSHA Compliant, Workshop, Business, Commercial Truck Vehicle DOT, Wall Mount Box, All-Purpose
185 pieces
OSHA 1910.151(b) listed
Metal case
3.85 pounds
+ The Good
- Metal housing outlasts plastic wall cabinets whose hinges go brittle
- Keyhole mounting tabs on two screws
- Extra interior room for a separate eyewash bottle
- Thermal Mylar blanket included
- The Bad
- Could include more nitrile gloves
- No CPR pocket mask
- Generic rather than premium adhesive bandages
The highest average rating in our set belongs to this one, 4.9 from a base of 46 reviews, so read it as a very well-liked recent product rather than a proven one. What contractors, woodworkers and shop owners consistently praise is the metal housing. Their specific comparison is to plastic wall cabinets whose hinges become brittle in sun and fail, which matches what we saw repeatedly across the other reviews in this roundup.
At 185 pieces, listed for up to 25 people under OSHA 1910.151(b), it is the one metal alternative at the same coverage tier as our top pick. The manufacturer describes keyhole mounting tabs that hang on two screws, plus an integrated carry handle and dual secure latches, so it mounts and un-mounts without tools.
The supply list is the standard contractor profile plus two items that are rarer than they should be: a thermal Mylar blanket for hypothermia, and burn gel. Owners like the Mylar blanket specifically because they never see it in comparable kits, and in winter or on a cold steel deck it is more than a nice inclusion.
There is also extra interior room over tighter cases, which one buyer used to add a separate eyewash bottle. That matters, because eyewash is a Class A requirement and buying it separately is a reasonable plan when the case gives you space for it.
Is a metal case always better than plastic?
Not always. Metal wins on impact, on hinge life in sun, on water ingress and on theft deterrence, and it is the right call for a fixed wall station in a rough building. Plastic wins on weight, on cost and on visibility, and it is entirely adequate for a dry indoor facility or a vehicle that stays under cover.
The practical failure we kept hearing about was never the case body, it was the plastic hinges and latches on cheap wall units cracking in heat. If you are buying plastic, buy a unit with slide latches rather than a hinged door, and mount it out of direct sun.
What to add before you call it done
Owners noted two gaps: more nitrile gloves and the absence of a CPR pocket mask, which one buyer added separately. A pocket mask is a bloodborne pathogen barrier requirement, so treat it as a must-add rather than a preference. Gloves are always worth stocking heavily, because any blood contact response consumes them.
The case is 12 by 11 by 4 inches at 3.85 pounds, so plan a personal trauma pouch alongside it if you work alone on a high-hazard job. The company is veteran-owned and California-based.
How to Choose a First Aid Kit for Your Crew?
Work through these in order. Compliance class first, because it determines what has to be inside, then coverage, then container, then contents depth, then how you will keep it stocked.
Get the class right before you compare anything else
Class A is the target for most construction and trade work. Class B is the right answer when hazardous materials, chemical exposure, demolition or heavy equipment raise the risk level, and it adds barrier protection and larger quantities of sterile dressings. Basic is for low-risk workplaces and should not appear in a job site cart. If a listing does not state a class anywhere, treat it as unclassified and assume it is not what you need.
Then size to simultaneous headcount plus a margin. A 25-person kit on a 40-person site is a shortage waiting to happen, and rotating subcontractor crews consume supplies faster than their headcount suggests. Buy one tier up if you are ever uncertain.
Count the areas, not just the people
This is the mistake that costs crews the most. Accessibility is about time and distance, not supply volume. If your work spans areas that a worker cannot reach in a minute, each area needs coverage. A second 25-person kit for the far end of the site is cheaper than the downtime from a worker walking for a missing dressing while a supervisor drives.
Multi-area projects, road crews and any site spread across multiple floors or blocks should assume a kit per area per shift, and vehicles should carry their own. A portable kit that lives permanently in a truck is not site coverage, it is vehicle coverage.
Choose the container for the environment
Metal for impact, heat, sun and theft. Plastic for weight, cost and visibility, mounted indoors away from direct sun. A wall-mounted case with a handle that unhooks gives you both the fixed station and the response kit, and it is the format we would standardise on across a company with several sites.
Water resistance is not the same as waterproof. Nearly every kit described as water resistant keeps out rain and dust but not a hose-down or a tipped water bottle. If the kit lives in an open truck bed, either accept replacement frequency or move to a sealed metal box.
Look for bleeding control, not bandage counts
Piece count is a poor proxy for capability. A kit with 300 adhesive bandages and no sterile gauze is less useful than one with 150 pieces including gauze pads, roller gauze, antiseptic, burn treatment, gloves and a barrier device. Only one kit in our roundup includes a tourniquet, and only a few include a pocket mask, so plan to add those deliberately.
For trades working around saws, rebar, blades or heavy equipment, treat a tourniquet, hemostatic gauze, a pressure bandage and chest seals as a separate personal purchase rather than an upgrade to the site box. Users on r/VEDC and r/TACMED101 consistently build around a quality tourniquet for exactly this reason, and treat the standard kit as a separate problem.
Buy for restockability, then check your temperature exposure
Before you commit, confirm a matching refill exists by part number. Kits with an included refill order form or a well-known model number restock in minutes. Assembled kits of loose components are the hardest to replenish, and a kit you cannot refill is a kit that gets replaced rather than restocked.
Then deal with the parked truck. Medications and some wound dressings degrade in sustained heat and can be damaged by freezing, and a vehicle interior swings between extremes. If your kit lives in a truck, take medication out to a climate-controlled space overnight, or accept that you are carrying a kit with a short service life and build the replacement into your inspection interval.
Do not skip training, the last requirement
The most common forum comment on job site kits is that the crew does not know what is inside it, so it goes unused. A fifteen-minute walkthrough at the toolbox talk, naming where the kit is, who restocks it and what it holds, is worth more than any feature on this list. Nominate one person as the inspection owner and give them a written monthly checklist with a sign-off line, because a task with an owner gets done and a task without one does not.
Run the sweep monthly and do a full expiry audit twice a year. Check that the case is sealed, that sterile packaging is intact, that no item is below its expiry, and that used supplies have been replaced and disposed of in a liquid-impervious container rather than returned to the case.
Frequently Asked Questions
What must be in a workplace first aid kit?
A workplace first aid kit must hold adequate, sealed supplies for the hazards present: adhesive bandages and medical tape, sterile gauze pads and rolls, triangular bandages, antiseptic and antibiotic applications, burn treatment, medical gloves, eye wash, and a barrier device for mouth-to-mouth resuscitation. OSHA requires these to be adequate for the hazards and readily accessible, and everything must remain in individual sealed packages to count.
Is there an OSHA approved first aid kit?
No. OSHA does not approve, certify or endorse any first aid kit or brand. What the agency requires is that supplies be adequate for the workplace hazards, kept in a durable container, and readily accessible to employees. When people say OSHA approved they usually mean a kit whose contents satisfy the applicable ANSI Z308.1 class for their hazard level and crew size.
What makes a first aid kit ANSI compliant?
Compliance means the kit meets the minimum supply list for its class under the ANSI Z308.1 standard, which is the specification OSHA refers to. Class A suits moderate-risk workplaces, Class B suits higher-risk work involving hazardous materials, and Basic is a low-risk floor. Check that the class, the crew capacity and the standard revision year are all stated, since kits are certified against a specific edition.
What type of first aid kit does a construction site need?
A construction site generally needs at minimum an ANSI Class A kit sized to the number of people on site, with heavier or Class B coverage where hazardous materials, demolition or heavy equipment raise the risk. Kits must be readily accessible, which usually means one kit per separate work area rather than a single kit in the site trailer, and additional supplies must be available for injuries more serious than minor wounds.
How many first aid kits does OSHA require on a job site?
OSHA does not set a fixed number of kits, it requires that supplies be readily accessible to every employee. In practice this means enough kits that a worker in any active work area can reach supplies quickly, which most contractors plan as one kit per crew per separate area, with a vehicle kit for anyone working away from the station. Coverage must add up to at least the total headcount on site.
Do OSHA first aid kits expire?
Yes. Sterile packaging loses its integrity over time, ointments and antiseptics have shelf lives, and adhesive dressings degrade in heat. An expired or open package does not count toward an adequate supply, so expired items must be removed and replaced. Inspected monthly and audited for expiry twice a year is a workable cadence, and medication stored in a hot or freezing vehicle degrades faster than the printed date suggests.
What is the best first aid kit for a work truck?
The best work truck kit is a sealed metal or hard plastic case that satisfies DOT and OSHA Class A requirements, mounts out of the way with hanging brackets, and is small enough to lift out and carry to an injured person. A waterproof seal matters more than piece count, because a vehicle kit is judged on surviving the trip rather than serving a crew. Add a pocket mask and extra gloves to whatever the manufacturer supplies.
What should I add to a compliant first aid kit for hemorrhage control?
Add items that standard OSHA kits leave out: a quality windlass tourniquet, hemostatic or compressed gauze, a pressure bandage, a CPR pocket mask with a one-way valve, and chest seals. Standard construction kits come with adhesive bandages and antiseptic wipes and rarely include any of these, so treat hemorrhage gear as a deliberate purchase. Train the crew to use the tourniquet before they need it, because an unused tourniquet is worth nothing.
Final Verdict: Which Job Site Kit Fits Your Crew
For most crews we recommend the First Aid Only 9302-25M 25-Person. It is a metal case that mounts, carries, opens one-handed and holds enough for 25 people, backed by 6,796 reviews with very little to go wrong over more than a decade. Buy the Be Smart Get Prepared 326-piece kit for a 100-person site, the 24/7 kit when you need a clear lid so anyone can spot a depleted shelf, and the MFASCO sealed box for commercial vehicles.
Pick the ANSI B+ kit if your crew works around blades, rebar or demolition. Whatever you choose, add a tourniquet, hemostatic gauze and a pocket mask as a deliberate purchase, and put a named person in charge of a monthly inspection with a sign-off line. That last part costs nothing and does more for your site than any feature on this list. As we covered in our construction site equipment guide, the unglamorous maintenance routine is what separates a compliant site from an audited one.
