# First Aid Kits

A first aid kit's real spec isn't its price or piece count, but what hazard tier and setting it's built for: workplace kits are sized against ANSI/ISEA Z308.1's Class A/B hazard tiers and OSHA's PPE rule, home kits against the Red Cross's family checklist, and outdoor kits against carry weight and real bleeding-control gear.

## How it works

A first aid kit pre-bundles, in one container, the small set of supplies a layperson can use in the first minutes after an injury: dressings and bandages to cover a wound, antiseptic to clean it, tape and gauze rolls to hold a dressing in place, and often gloves and a CPR breathing barrier to protect the responder from the patient's blood. Workplace kits size and classify that bundle against the ANSI/ISEA Z308.1 standard, which scales item types and quantities to a hazard class and a headcount, though OSHA treats that standard only as a non-mandatory example. Home kits instead follow a looser consumer checklist like the Red Cross's. Serious trauma and backcountry kits add a tourniquet and hemostatic gauze, because pressure dressings alone are too slow for bleeding that could kill a remote patient before help arrives.

   Skip if already known: a query that already names 'workplace', 'office', 'home', 'family', 'hiking', 'camping', or 'car', an earlier answer naming an ANSI class or a trip-duration tier.

2. **ANSI hazard class.** Low-risk office, or a higher-hazard worksite?
   Class B kits carry more item types and larger quantities than Class A under ANSI/ISEA Z308.1, since the standard assumes more frequent, more severe injuries at higher-hazard sites.
   Skip if already known: an earlier answer naming 'office', 'warehouse', 'manufacturing', or a stated ANSI class.

## What to surface

### Setting and audience

What setting and audience the kit is built for: a workplace kit sized to an ANSI/OSHA headcount, a home kit for a family, an outdoor/wilderness kit for hikers and campers, or a compact vehicle/travel kit. Setting decides which specs matter at all: workplace kits are judged against ANSI/OSHA headcount tables, home kits against the Red Cross family checklist, outdoor kits against weight and bleeding-control gear, and vehicle kits against compactness and case durability. [3] [9]

Values: workplace_ansi, home_family, outdoor_wilderness, vehicle_travel.
Question to ask: Workplace, home, outdoor/camping, or car kit?

Used as: top-level split, filter. Data: derived from listing fields, backfill cost low. Look for it as: Usually stated in the title or category, e.g. 'Workplace First Aid Kit', 'Family First Aid Kit', 'Hiking First Aid Kit', 'Car Emergency Kit'.
Title keyword match covers almost every listing; default ambiguous small kits to home_family.

### ANSI hazard class

ANSI/ISEA Z308.1's two hazard tiers for workplace kits: Class A for lower-hazard workplaces like offices, Class B for higher-hazard sites like manufacturing, with more item types and larger quantities. Class B kits exceed Class A on both the number of supply types and the quantity of each, because the standard assumes more frequent and more severe injuries at higher-hazard sites; under-classifying leaves a kit compliant on paper but short on supplies in practice. [5] [7]

Values: class_a, class_b, unspecified.
Question to ask: Low-risk office, or a higher-hazard worksite?

Used as: top-level split, filter. Data: on the listing, backfill cost low. Look for it as: Stated in the title as 'ANSI A' or 'ANSI B', or 'Class A'/'Class B'.
Title keyword match; cross-check against the stated piece count, since Class B kits run far higher.
Chart: two-tier position, Class B above Class A on a hazard scale.

### People covered

The headcount the vendor rates the kit for, such as '10 Person' or '25 Person'. This is the sizing convention printed on nearly every ANSI kit, but it is a vendor table entry, not a measured injury-coverage count, so it compares reliably within one brand's line and only loosely across brands. [5] [7]

Range: 1 to 200 people. ANSI kits are commonly rated 10, 25, 50, or 100 person; home kits are usually rated for a family of four.
Question to ask: Roughly how many people need covering?

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Stated in the title as 'X Person', e.g. '10 Person ANSI A Kit'.
Title keyword match for the number immediately before 'Person'.
Chart: position on a people-covered scale.

### ANSI certification

Whether the kit's contents are built to meet the ANSI/ISEA Z308.1 standard for workplace first aid kits, and which edition. OSHA's own first-aid rule carries no required item list; its non-mandatory Appendix A simply points to ANSI/ISEA Z308.1 as an example of adequate minimum supplies, so a kit marketed as the 2021 edition carries more item types and quantities than the 1998/2009 editions it replaced. [2] [5] [1]

Values: ansi_isea_z308_1_2021, ansi_isea_z308_1_2009_or_earlier, not_ansi_rated.
Question to ask: Does it need to meet a workplace safety standard?

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Stated directly in the title, e.g. 'ANSI 2021 Compliant' or 'Meets ANSI Z308.1'.
Title keyword match for 'ANSI' plus the year; default to not_ansi_rated when absent.

### Employee headcount band

The employee-count range a workplace kit's vendor sizes it for, printed alongside the ANSI class. Vendors scale the ANSI class and the headcount band together: a 10-person Class A kit is sized for roughly 1-24 employees, a 100-person Class B cabinet for 100-149, so buying by headcount alone without checking the hazard class can leave a high-risk site under-supplied. [5] [7]

Values: up_to_24, 25_to_49, 50_to_99, 100_to_149, 150_plus.
Question to ask: Roughly how many employees at this worksite?

Used as: filter, sortable. Data: derived from listing fields, backfill cost low. Look for it as: Not printed as a band on the listing; derive from the vendor's stated 'X Person' rating mapped to its own headcount-band table.
Map the stated person-rating to the vendor's band table; bands vary slightly by vendor.
Chart: position on a headcount scale.

### Kit weight

How much the kit weighs, including its case. Weight is the direct trade against supply breadth for anything carried: an ultralight day kit and a comprehensive backcountry kit from the same category can differ by a factor of ten, and a buyer who'll carry the kit has to decide how much coverage is worth the ounces. [9] [5] [7]

Range: 4 to 224 oz. Ultralight day kits run 4-8 oz; comprehensive backcountry/car-camping kits run 24-48 oz (1.5-3 lb); stocked ANSI workplace kits and cabinets run from about 2.3 lb up to roughly 14 lb (13.95 lb for a 100-person Class B cabinet).
Question to ask: How much extra weight can you carry?

Used as: shown on the card, sortable. Data: on the listing, backfill cost low. Look for it as: Stated as a weight spec, in oz or lb.
Almost always on the spec sheet; if absent, estimate from the case dimensions and material.
Chart: position on a log weight scale, oz to lb.

### Trip-duration tier

How far the user will be from a vehicle or professional care: kits built around quick access to a car or home, a single day out, or multiple nights remote. Reviewers size backcountry kits to how long it would take to reach help: a day-trip kit skips the splinting and heavy wound-closure gear a multi-day kit needs, because a day-tripper can get a patient to a car fast while an overnight trip has to stabilize for hours. [9]

Values: home_or_vehicle_access, day_trip, overnight_multi_day.
Question to ask: A day trip, or one or more nights out?

Used as: filter, shown on the card. Data: needs research, backfill cost medium. Look for it as: Rarely a plain listing field; the product line name ('Day Tripper' vs 'Expedition') carries it, but most retail listings drop that branded name.
Keyword match on the product line name when present; otherwise read the description or default to day_trip.

### Medication included

What over-the-counter medication, if any, ships in the kit: none, basic pain/allergy tablets (aspirin, antihistamine), or those plus topical treatments (hydrocortisone, antibiotic ointment). Medication varies even within workplace ANSI kits: a Class A kit may ship none, while a Class B cabinet can include OTC pain and antacid tablets; the Red Cross's own recommended home kit adds aspirin, antihistamine, and hydrocortisone, so a buyer can't assume either a workplace or a home kit's medication content from its setting alone. [4] [5]

Values: none, otc_pain_and_allergy, otc_pain_allergy_and_topical.
Question to ask: Should it include basic pain and allergy medication?

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Scan the contents list for aspirin, antihistamine, or hydrocortisone.
Keyword-scan the contents table for aspirin, antihistamine, or hydrocortisone; default to none only when no medication line appears, regardless of kit type.

### Waterproofing

Whether the case keeps its contents dry: no particular resistance, splash/rain resistant, or a fully sealed/submersible waterproof case. A soaked gauze pad or adhesive bandage is useless, so reviewers single out kits with a sealed case as the right pick for paddling, wet climates, or boat storage, and treat a merely 'water-resistant' claim as a weaker guarantee. [9]

Values: not_water_resistant, water_resistant, fully_waterproof_sealed.
Question to ask: Will it get rained on, dunked, or stay dry?

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Stated directly, e.g. 'waterproof case' or 'water-resistant'.
Title/description keyword match; default to not_water_resistant when unstated.

### Case form factor

The kit's physical housing: a soft zippered pouch or bag, a rigid hard-shell case, a wall-mounted cabinet, or a simple cardboard/plastic box. Form factor decides where a kit actually lives: a soft pouch compresses into a pack or glovebox, a hard case protects contents from crushing in a toolbox or trunk, and a wall cabinet is meant to stay fixed at a facility, not travel. [5] [7]

Values: soft_pouch, hard_case, wall_cabinet, box.
Question to ask: A soft pouch, a hard case, or a wall cabinet?

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Usually visible in the product photos and stated in the title.
Title/image keyword match; default to soft_pouch for small kits, box for basic home kits.

### Bleeding-control gear

How far a kit goes on severe bleeding: basic gauze/pressure dressings only, adding a commercial tourniquet, or a full loadout with a tourniquet, hemostatic gauze, and a chest seal for penetrating chest wounds. Civilian trauma deaths are often driven by bleeding a bystander could have stopped faster with a tourniquet than with pressure alone; the American College of Surgeons' Stop the Bleed program trains on exactly this gear, and reviewers flag kits without it as unsuitable for serious backcountry or workplace trauma. [9] [8] [7]

Values: dressings_and_direct_pressure_only, includes_tourniquet, includes_tourniquet_hemostatic_and_chest_seal.
Question to ask: Just bandages, or bleeding-control gear like a tourniquet?

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Check the contents list for 'tourniquet', 'hemostatic', or 'chest seal'; absent means dressings-only.
Keyword-scan the contents table; most basic/home kits lack all three.
Chart: three-tier position on a bleeding-control-capability scale.

### Piece count

The total number of individual items packed in the kit, as stated by the vendor. Piece count alone is misleading without context: a kit can hit a high count by stacking cheap adhesive bandages rather than covering the trauma, burn, and medication categories a buyer actually needs, so experts read it alongside the contents breakdown, not on its own. [5] [7]

Range: 5 to 700 pieces. Small pouch kits run under 50 pieces; ANSI Class A workplace kits run 70-100; ANSI Class B cabinets run several hundred.

Used as: shown on the card, sortable. Data: on the listing, backfill cost low. Look for it as: Often in the title as '## Piece' or '## Unit', or in a spec table row.
If absent from the listing, the brand spec sheet's contents table always has it.
Chart: position on an item-count scale, annotated by kit_type.

### Bloodborne-pathogen PPE included

Whether the kit includes personal protective equipment for bloodborne pathogen exposure: gloves, a CPR breathing barrier/face shield, and sometimes eye protection. OSHA's Bloodborne Pathogens standard (1910.1030(d)(3)) requires employers to provide this PPE wherever first aid could expose a responder to blood, so a workplace kit without gloves and a rescue breathing barrier forces the buyer to source that PPE separately to stay compliant. [2] [5]

Values: included, not_included.
Question to ask: Does it need gloves and a CPR breathing barrier?

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Check the contents list for 'gloves', 'CPR face shield', or 'breathing barrier'.
Scan the listed contents table; most ANSI-compliant kits include this, generic bandage-only kits often don't.

### Splint for fractures

Whether the kit includes a splint, such as a padded flexible splint or a SAM splint, for immobilizing a suspected fracture or sprain. Gauze, tape, and even a tourniquet stop bleeding but do nothing to immobilize a broken limb; splinting is its own spec-sheet line separate from bleeding-control gear, and reviewers call out a missing splint as a real gap, so a kit can score well on tourniquets and still ship nothing to stabilize a fracture. [7] [9]

Values: included, not_included.
Question to ask: Does it need a splint for fractures?

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Check the contents list for 'splint' or 'SAM splint'.
Keyword-scan the contents table for 'splint'; default to not_included when absent.

### Case material

What the kit's case or cabinet is made of: metal, plastic, or soft fabric. A metal case survives crushing and job-site abuse better and often carries the ANSI container-durability rating, but costs more and weighs several times as much as the identical kit in a plastic case; a buyer trading off durability against weight and price needs this spec, which case_form_factor's pouch/case/cabinet/box shape doesn't capture. [5] [6]

Values: metal, plastic, fabric_or_unspecified.
Question to ask: Metal case, or plastic?

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Spec table 'Material' row, or stated in the title as 'Metal' vs 'Plastic'.
Title/spec-sheet keyword match for 'metal' or 'plastic'; default to fabric_or_unspecified for soft pouches.

### Container durability

The container's build and mounting: a stationary wall-mounted cabinet, a portable case rated weatherproof, or a portable case rated water-resistant/sealed. ANSI/ISEA Z308.1 sets container-type rules along this spectrum. A kit can meet the Class A or B contents requirement and still fail a job site if the case can't survive the environment: a cabinet-style case won't hold up outdoors, while a sealed portable case is heavier and costlier than an office breakroom needs. [3] [5]

Values: stationary_cabinet, portable_weatherproof_case, portable_water_resistant_case.
Question to ask: Indoors only, outdoor-exposed, or wet conditions?

Used as: filter, shown on the card. Data: needs research, backfill cost medium. Look for it as: Rarely a labeled field; infer from the case description ('metal cabinet' vs 'weatherproof case' vs 'waterproof case').
Keyword-match the case description; default to portable_weatherproof_case when unclear.

### Matches Red Cross checklist

How a home-oriented kit's contents compare, item by item, to the American Red Cross's published family-of-four first aid kit checklist. The Red Cross checklist is the closest thing to a consumer benchmark for a home kit (dressings, bandages, tape, antiseptic, aspirin, gloves, a thermometer, triangular bandages); a 'family first aid kit' missing half those items is thinner than the reference most buyers expect. [4]

Values: meets_or_exceeds, partial, basic_only.

Used as: filter, shown on the card. Data: derived from listing fields, backfill cost medium. Look for it as: Compare the stated contents list item-by-item against the Red Cross checklist.
Requires the full contents list, not just a piece count; many listings only give a total count.
Chart: percent-of-checklist-met bar.

### Refill kit available

Whether the vendor sells a matching refill kit to restock used or expired contents without buying a new case. A kit with a sold refill SKU is cheaper to maintain over years, since a buyer replaces only the consumed items and keeps the case; ANSI workplace cabinets are built around this refill model, while many cheap bundled kits have no separate refill and get thrown out whole. [7]

Values: refill_kit_sold_separately, standalone_only.
Question to ask: Want a kit you can refill later, or one-and-done?

Used as: filter, shown on the card. Data: needs research, backfill cost medium. Look for it as: Rarely a listing field; check whether the vendor's catalog lists a 'refill' SKU matching the kit model.
Search the vendor's catalog for '<model> refill'; ANSI cabinet brands almost always have one.

## Numbers worth computing

| Metric | Formula | Why |
|---|---|---|
| Pieces per pound (pieces/lb) | `stated piece count / kit weight in pounds` | A low pieces-per-pound ratio signals a kit carrying weight in a few heavy single-purpose items (splints, a hard case, a tourniquet) rather than breadth of small consumables; the two ANSI spec sheets here run roughly 33-49 pieces/lb, a baseline a buyer can check any listing against once it states both numbers. [5] [7] |

## What you give up

- A kit built for a day trip near a car can weigh well under half a pound; adding the tourniquet, chest seals, and airway tools reviewers want for multi-day backcountry trips pushes a comparable kit to roughly 2-3 pounds and several times the cost. [9] Board branch: "More trauma capability, more weight and cost".

## Where we made a call

- OSHA cites ANSI Z308.1 only as a non-mandatory example, not a mandatory content list. (confidence high). OSHA's own Appendix A labels the ANSI example 'Non-Mandatory'; retail listings market ANSI compliance as if it were the legal requirement. [2] [3]
