Best Home First Aid Kit for Contractors by Piece Count

The best home first aid kit for contractors is the First Aid Only 9302-25M, a 178-piece kit in a 1.38 lb wall-mountable metal case rated for 25 people. If you need a smaller kit that lives in a truck glove box, the ProHeal 111-piece OSHA-compliant kit at 7.87 x 2.76 x 5.12 in is the better buy. Both cover the same core injuries; the difference is where the kit lives and how many hands reach into it.

Best home first aid kit for contractors at a glance

How I screened the field down to five

I started with the First Aid category on Amazon, filtered to kits described by the listing as suitable for contractors, construction sites or work vehicles, and threw out anything with fewer than 100 pieces. That cut on piece count matters. A 50-piece kit works for a bathroom cabinet; a contractor rakes through supplies fast, because a single deep cut can burn a dozen gauze pads and half the tape.

Three reasons picks got cut:

• No mounting option. A first aid kit that lives loose in a truck cab slides under the seat the first time you brake hard. Every finalist here mounts to a wall or shelf.
• Vague piece counts. Listings that promised "everything you need" without a number went straight in the bin. The five here all publish an exact count.
• No OSHA reference or contractor use case. For a contractor buying a "home" kit, OSHA compliance is not required, but the presence of that language usually correlates with useful gauze, burn cream and glove supplies rather than a box of adhesive bandages.

Five kits cleared all three cuts: two from First Aid Only, one each from ProHeal, EVERLIT and TLIEAO. Two use metal cases and three use plastic. Piece counts run from 111 to 400. That range is not accidental, it is the real spread of what a contractor might reasonably buy for the home base.

Metal case or plastic: which survives a job site?

Case material is the single feature buyers overpay for without understanding what they are paying for. Metal is not automatically better.

A metal case takes a crush better than plastic and mounts flush to a garage stud without flexing. The First Aid Only 9302-25M and the EVERLIT 185-piece kit both use metal, and both weigh more for it: 1.38 lb and 3.85 lb respectively. Plastic is lighter, cheaper, and easier to wipe down when something inside leaks. The ProHeal, the budget First Aid Only 9301-25P, and the TLIEAO all use plastic.

If the kit lives on a wall in a heated garage or workshop, metal is worth it. If it lives in a truck that sees 100°F cab temperatures in summer, plastic contents will fare no worse than metal, and the case itself will not rust when a wet glove goes back inside. The deciding question is not durability in the abstract, it is which failure mode you actually face.

1. First Aid Only 9302-25M — Best overall

A wall-mountable 178-piece metal kit rated for 25 people that reads like the default answer to this question.

Best for: a contractor who wants one wall-mounted kit for the garage workshop and the truck Skip it if: you need a kit small enough to live in a glove box

Inside this set of five, the 9302-25M is the one that answers the widest brief. It carries 178 pieces, sits inside a metal case with an easy-release latch and a carry handle, and weighs just 1.38 lb empty enough to move between a shop wall and a truck bed without complaint. First Aid Only lists adhesive fabric and plastic bandages, antibiotic ointments, BZK antiseptic towelettes, burn cream packets, gauze rolls and pads, and gloves as the contents. That mix is the right one for the injuries a contractor actually sees: shallow cuts from utility knives, splinters, friction burns from a rope or a hot tool, and pinches from framing timber. The listing dates the design to 2013, which is worth knowing: the case shape and latch have been in production long enough that replacement supplies are easy to source. Against the two premium picks it gives up piece count, and against the budget First Aid Only kit it gives up compactness. The trade is worth it for the metal case and the 25-person rating.

Pros:

• Metal wall-mount case with carry handle
• 178 pieces and 25-person rating
• Only 1.38 lb empty
• Long-running design with restockable contents
• Manufacturer warranty listed

Cons:

• Larger than a glove-box kit
• Mid-range price for the piece count
• No OSHA-compliance language in the listing

2. ProHeal 10-Person OSHA Kit — Most versatile

A 111-piece OSHA-compliant plastic kit small enough to live in a truck glove compartment and still mount to a wall.

Best for: a solo contractor who moves between the truck cab and a small home office Skip it if: you want a metal case or a piece count above two hundred

The ProHeal is the only kit here that credibly does two jobs. At 7.87 x 2.76 x 5.12 in, it is small enough to slide into a truck glove compartment or console, and it still ships with wall-mount hardware for a fixed home base. ProHeal describes the kit as OSHA compliant, Type III, ANSI Class A, and rates it for 10 people. The 111 pieces cover gauze, bandages, burn cream, cotton applicators, gloves, alcohol prep pads and triple antibiotic ointment, per the listing. ProHeal says the case is latex-free and includes a manual, which matters more than it sounds: on the first ugly cut, whoever grabs the kit is not the person who packed it. Compared to the two First Aid Only kits, you lose about 65 pieces of supply and the metal shell. You gain a form factor that fits places the others do not, and the OSHA labelling that most contractor buyers actually want on paper. It is the second-cheapest of the five here.

Pros:

• OSHA compliant, Type III, ANSI Class A
• Fits a truck glove compartment
• Wall-mountable plastic case
• Latex-free contents
• Includes a manual and guide

Cons:

• Lowest piece count of the five
• Plastic case, no metal option
• Rated for only 10 people

3. First Aid Only 9301-25P — Best budget pick

Almost the same 25-person kit as the winner in a plastic case, and the cheapest of the five here.

Best for: a home renovator kitting out a second location on a tight budget Skip it if: you want a wall-mount metal case rather than a plastic clamshell

The 9301-25P is what happens when you take the metal off the winner. It carries 176 pieces against the 9302-25M's 178, weighs 1.2 lb against 1.38 lb, and measures 6 x 9.06 x 2.38 in in a plastic case. First Aid Only lists the same core mix: adhesive fabric bandages, burn cream, gauze rolls and pads, gloves, scissors, and other multi-use items. It is the cheapest of the five here and the slowest seller of the set, which is worth reading carefully. Slow-selling in first aid is not a warning the way it is in electronics; the supplies inside are the same, and the design has been in production since 2013. Buyers just pick the metal version more often. If the kit is going to live in a drawer or on a shelf indoors, the plastic case does the same job for less money. Against the ProHeal, it gives up the explicit OSHA labelling but nearly doubles the piece count.

Pros:

• Cheapest kit in this set
• 176 pieces at 1.2 lb
• Slim 2.38 in depth fits a drawer
• Same core contents as the winner
• Easy-release latches for one-hand opening

Cons:

• Plastic case, not wall-mount metal
• No OSHA-compliance language
• No warranty stated in the listing

4. TLIEAO 400-Piece All-Purpose Kit — Best premium

A 400-piece dual-layer wall-mount kit that swallows a shop's worth of restock in one case.

Best for: a general contractor who wants one deep kit for the shop and a second family vehicle Skip it if: you strictly want an OSHA-labelled kit for a job site inspection

The TLIEAO is where the piece count stops being reasonable and starts being generous. 400 pieces sit inside a 12.2 x 4.13 x 13.4 in red plastic case that opens on two tiered shelves under a transparent lid, per the listing. That layout matters. In every other kit here, the contents live in one flat compartment and you sift through them under stress; TLIEAO says the tiered design lets you see what is where before you dig. It is the most expensive pick here and the fastest seller of the five, which tells you the piece count and the layout are doing more work for buyers than the OSHA badge does elsewhere. The trade against the two First Aid Only kits is real: no OSHA labelling in the listing, no explicit contractor-specific mix, and a case that is nearly double the depth. Against the EVERLIT, you get more than double the pieces at the cost of a plastic shell rather than metal.

Pros:

• 400 pieces, the deepest kit here
• Dual-layer tiered organisation
• Transparent lid for fast identification
• Wall-mountable and portable
• Fastest-selling of the five

Cons:

• No OSHA-compliance language
• Plastic case, not metal
• Bulkier than any other pick here

5. EVERLIT 185-Piece Metal Kit — Best upgrade

A commercial-grade metal kit that explicitly cites OSHA 1910.151(b) and DOT vehicle use.

Best for: a contractor whose truck also serves as a DOT-regulated work vehicle Skip it if: you want the highest piece count you can find

The EVERLIT is the most narrowly targeted kit in this set, and that is its strength. 185 pieces sit inside a metal case measuring 4 x 12 x 11 in at 3.85 lb, and EVERLIT cites OSHA 1910.151(b) directly and calls out DOT trucks and commercial vehicles as the intended home. If your truck falls under DOT rules and you want a kit whose paperwork lines up cleanly, this is the one that says so on the label. The contents cover cuts, scrapes, burns, minor wounds, hypothermia and acute injuries per the listing. It is heavier than the two First Aid Only kits by more than 2 lb, and against the TLIEAO it gives up more than half the piece count. What you buy in exchange is the metal shell, the explicit regulatory language, and a form factor that fits a bulkhead mount rather than a glove box. Against the winner, it costs more for a similar piece count.

Pros:

• Metal wall-mount case
• Cites OSHA 1910.151(b) directly
• 185 pieces including hypothermia items
• Sized for a truck bulkhead mount
• Commercial-grade positioning

Cons:

• 3.85 lb, heaviest kit here
• Fewer pieces than the TLIEAO
• Premium price for the piece count

What OSHA compliance actually promises you

OSHA compliance is the term most heavily marketed on contractor first aid kit listings, and the one most buyers misread. It matters, but not the way people think.

OSHA 1910.151(b) requires an employer to provide adequate first aid supplies when a medical facility is not nearby. ANSI Z308.1 sets the actual contents that satisfy that requirement, and it defines Class A kits for low-risk environments and Class B kits for higher-risk ones. The ProHeal here is labelled Type III, ANSI Class A. The EVERLIT cites OSHA 1910.151(b) directly. The two First Aid Only kits are described as contractor kits without invoking OSHA on the listing.

For a home kit, none of that is legally required. You are not the employer, the garage is not the job site, and no inspector will read your label. What OSHA and ANSI language does buy you is a reliable minimum: gauze, gloves, burn cream, antiseptic, and enough of each that one accident does not empty the box. That is why the label still earns its place in the shortlist, even for a home kit. It is a proxy for content quality, not a legal document you need on your own property.

How many people is the kit really rated for?

Person ratings on first aid kit listings are a rough guide, not a promise. Read them as a proxy for total supply depth.

• The First Aid Only 9302-25M and 9301-25P are both rated for 25 people, with 178 and 176 pieces respectively.
• The ProHeal is rated for 10 people, with 111 pieces.
• The TLIEAO and EVERLIT do not publish a person rating; they publish piece counts of 400 and 185.

The rule of thumb: divide the piece count by the person rating and you get a rough number of supplies per person. The First Aid Only kits land near 7 pieces per person, the ProHeal near 11. That is not because the ProHeal is more generous per person, it is because a 10-person rating assumes fewer injuries between restocks. What you actually want to ask is how many separate incidents a kit can cover before you refill it. A single deep laceration can burn 6 to 10 gauze pads and half a roll of tape by itself. A kit with 111 pieces covers perhaps two of those before it needs restock; a 400-piece kit covers a shop through a busy quarter.

What to restock first, and how often?

A first aid kit stops being a kit the first time someone opens it. Restocking is the maintenance step buyers skip.

1. Check gauze and adhesive bandages monthly. These go first, always. Both First Aid Only kits and the EVERLIT rely on generous bandage counts; the moment you dip below a dozen assorted sizes, restock.
2. Check gloves and antiseptic quarterly. Nitrile gloves dry out in a hot truck cab. BZK antiseptic towelettes, which the 9302-25M lists, evaporate through their foil if a seal has been compromised.
3. Check burn cream and antibiotic ointment annually. These carry expiry dates. A kit from 2013 does not have 2013 ointment inside; the supplies are refreshed. But once opened, the clock is real.
4. Rotate the whole kit every three years. Not because the case fails, but because half the small items get consumed or moved without you noticing.

Set a calendar reminder. That single step is what separates a kit that works from a shelf ornament.

The verdict

The First Aid Only 9302-25M wins as the best home first aid kit for contractors because it does the widest job with the fewest compromises: 178 pieces, a 25-person rating, a 1.38 lb metal wall-mount case, and a design that has been in continuous production long enough that replacement supplies are trivial to source. It is not the biggest kit here and it is not the cheapest, but nothing in this set covers more scenarios per pound of case weight.

The runner-up is the ProHeal 111-piece OSHA-compliant kit, and it wins on one axis the 9302-25M cannot match: it fits in a truck glove compartment at 7.87 x 2.76 x 5.12 in and still mounts to a wall. If your kit needs to travel between the home base and the cab, the ProHeal is the better buy.

If piece count is what decides it for you, the TLIEAO 400-piece kit is the deepest option here and the fastest seller of the five. If your truck falls under DOT rules and you want a kit whose paperwork lines up cleanly, the EVERLIT cites OSHA 1910.151(b) directly and is built around that use case. And if budget is the whole conversation, the First Aid Only 9301-25P gets you 176 pieces in a plastic case for the least money in the set.

FAQ

Is the best home first aid kit for contractors different from a standard home kit?

The best home first aid kit for contractors differs from a standard home kit mainly in supply depth and case build. A standard home kit is built around adhesive bandages for a family. A contractor kit carries more gauze, more gloves, burn cream, and a mountable case, because the injuries are messier and the kit lives in a shop rather than a bathroom cabinet.

Is a metal case worth it over plastic for a contractor kit?

A metal case is worth it if the kit lives on a shop wall or takes physical abuse. The First Aid Only 9302-25M and the EVERLIT both use metal and both mount cleanly to a stud. Plastic cases like the ProHeal, the 9301-25P and the TLIEAO are lighter, cheaper, and wipe clean more easily. The failure mode you actually face decides it.

How many pieces does a contractor's home first aid kit need?

How many pieces you need scales with how often the kit sees use. A solo contractor with occasional injuries is well served by the 111-piece ProHeal or the 176-piece First Aid Only 9301-25P. A busy shop that runs through supplies weekly wants the 178-piece 9302-25M at minimum, and the 400-piece TLIEAO if a single kit needs to cover a full quarter between restocks.

First Aid Only 9302-25M or ProHeal 111-piece: which for a work truck?

First Aid Only 9302-25M or ProHeal for a work truck depends on where the kit lives inside the truck. The ProHeal at 7.87 x 2.76 x 5.12 in fits a glove compartment or centre console. The 9302-25M at 1.38 lb in a metal case fits a bulkhead mount behind the cab. Pick the one that matches your actual mounting spot, not the piece count.

What is the biggest mistake buying a contractor first aid kit?

The biggest mistake buying a contractor first aid kit is treating the purchase as one-time. A kit that lives on a shelf for three years without a restock is not a first aid kit, it is a memory of one. Set a monthly reminder to check gauze and adhesive bandages, quarterly for gloves and antiseptic, annually for ointments, and rotate the full kit every three years.

If you want one kit that answers the widest brief for a contractor's home base, buy the First Aid Only 9302-25M and mount it in the shop on your way home. It is the pick that survives the widest set of scenarios: a splinter, a knife slip, a friction burn, a helper who does not know where anything is kept. The metal case takes abuse, the 25-person rating gives you real supply depth, and the design is old enough that restocking a year from now will not turn into a scavenger hunt. Buy it, mount it, then set a calendar reminder for a month from today to check the gauze count. That reminder is the pick's other half.
