Shopify first aid kit schema for AI agents: OSHA 1910.151 "adequate" does not specify kit contents — JHA-driven hazard selection, ANSI Z308.1 Class A vs Class B adequacy gap, tourniquet necessity for amputation-risk workplaces, STOP THE BLEED CAT Gen7 and hemostatic gauze for manufacturing and construction

OSHA 1910.151(b) — What "Adequate" Actually Requires

The full text of 29 CFR 1910.151(b) is brief: "In the absence of an infirmary, clinic, or hospital in near proximity to the workplace which is used for the treatment of all injured employees, a person or persons shall be adequately trained to render first aid. Adequate first aid supplies shall be readily available." Nothing more is specified at the regulatory level.

The operative word — "adequate" — is deliberately non-prescriptive. OSHA chose this language to allow the standard to apply across the full range of American workplaces, from single-occupant home offices to open-pit mines. A single standard with a fixed kit content list would over-specify for low-hazard settings and under-specify for high-hazard ones. The flexibility is intentional. The liability for the employer is also intentional: "adequate" must be demonstrated through reference to workplace hazards, not through reference to a label on a kit box.

OSHA's compliance directive CPL 02-02-053 ("Inspection Procedures for 29 CFR 1910.151 and 1926.50, First Aid") provides the enforcement framework. The directive instructs compliance officers to evaluate first aid kit adequacy by examining:

• The types of injuries and illnesses that can reasonably be expected to occur at the worksite
• Whether the kit contents are appropriate to treat those injuries and illnesses
• Whether the quantities of supplies are sufficient for the number of employees and the expected injury rate
• Whether the employer's first aid person(s) have been trained to use the available supplies

OSHA CPL 02-02-053 references ANSI Z308.1 explicitly as "a useful guide for providing proper first aid supplies" — not as a compliance safe harbor. An employer who stocks an ANSI Z308.1-compliant kit but whose workplace hazards require additional items (tourniquets, hemostatic gauze, eye wash, burn dressings) remains subject to citation under 1910.151(b) for failing to maintain adequate first aid supplies relative to the actual hazard profile.

ANSI Z308.1-2021 — Class A vs Class B Contents and Limits

ANSI Z308.1, published by the International Safety Equipment Association (ISEA) and the American National Standards Institute, defines minimum required items for occupational first aid kits in the United States. The 2021 revision reorganized the standard into two hazard-based classes (replacing the prior single minimum) and four physical form types.

Class A — Low-Hazard Minimum

Class A is calibrated for a general, low-risk workplace where the expected injury profile is minor cuts, abrasions, punctures, and mild burns. The 2021 minimum includes:

Class B — Higher-Hazard Minimum

Class B contains the same item categories as Class A with larger quantities and additional items targeted at higher-hazard environments. Class B adds eye pads, a breathing barrier for CPR, splint material, and larger quantities of dressings. Class B is intended for workplaces where injuries are more frequent or potentially more serious than the Class A baseline.

The critical point: neither Class A nor Class B includes a tourniquet, hemostatic gauze, chest seal, or needle decompression device. ANSI Z308.1-2021 explicitly notes that the standard addresses "first aid kit minimum content" for typical workplace injuries and that certain specialized items (defibrillators, tourniquets, hemostatic agents) are outside the scope of the standard because their need is hazard-specific and requires separate determination.

Class A Is Not a Safety Floor for High-Hazard Workplaces

A common misunderstanding in catalog routing — and in employer compliance decisions — is that Class A represents a universal minimum: that any employer who stocks a Class A kit is at least minimally compliant with OSHA 1910.151(b). This is incorrect. The Class A content is adequate for a low-risk workplace. For a construction site, a manufacturing floor with power presses, a logging operation, or a chemical processing facility, a Class A kit is a starting point — not a floor.

The JHA Requirement — Hazard-Relative Adequacy

OSHA CPL 02-02-053 translates the "adequate" standard into a practical requirement: the employer must assess workplace hazards and select first aid kit contents that address those hazards. This is functionally a Job Hazard Analysis (JHA) for first aid — the same methodology defined in OSHA 3071 ("Job Hazard Analysis") applied to the specific question of what injuries might occur and therefore what first aid supplies must be available.

The JHA for first aid kit adequacy asks three questions for each significant job or process in the workplace:

1. What injury types could result from this job step or process? (Laceration, amputation, burn, crush, eye exposure, inhalation, fracture, electrical shock, drowning, etc.)
2. What severity could that injury reach before EMS arrival? (Minor, serious, life-threatening)
3. Is the required first aid intervention within scope of lay rescuer capability and available kit supplies?

The output of this analysis drives kit content selection. The analysis must be written and retained — OSHA compliance officers may request the hazard assessment documentation during inspection. An employer who says "we have a Class B ANSI kit" without hazard documentation is in a weaker compliance position than one who presents a written JHA showing that the kit contents match the identified hazard profile.

When ANSI Class B Is Still Insufficient — Tourniquets and Hemorrhage Control

Traumatic hemorrhage from extremity injuries is the leading cause of preventable death in both military and civilian trauma settings. The most comprehensive civilian data comes from the Hartford Consensus (2013), a collaboration of trauma surgeons, law enforcement, and emergency medicine specialists convened after the Sandy Hook shooting. The Hartford Consensus established that up to 20% of traumatic deaths in high-energy civilian incidents (mass casualty, industrial accidents, transportation crashes) involve extremity hemorrhage that is survivable with tourniquet application but lethal without it.

OSHA CPL 02-02-053 recognizes this explicitly for industrial workplaces: an employer whose JHA identifies traumatic amputation or severe extremity crush as a plausible injury outcome is expected to include tourniquet capability in the first aid kit. The standard for what constitutes "adequate" first aid for an amputation includes tourniquet application — a Class B kit without a tourniquet is not adequate for a punch press operation where finger, hand, or arm amputations occur.

Why ANSI Z308.1 Excludes Tourniquets

ANSI Z308.1 addresses minimum content for a broad category of workplaces — it is calibrated to the center of the distribution of workplace injury profiles, not the high end. Including tourniquets in the Class B minimum would impose a requirement on low-hazard employers (office administrators, retail clerks, insurance agents) for whom tourniquet supplies represent a cost with essentially zero expected benefit. ANSI's scope statement acknowledges this explicitly.

The exclusion of tourniquets from the ANSI standard does not mean they are optional for high-hazard workplaces. It means the determination of tourniquet necessity has been delegated to the employer's hazard analysis — which is exactly where OSHA CPL 02-02-053 places it. For a Shopify catalog selling first aid kits, the implication is that the product description cannot simply say "compliant with ANSI Z308.1 Class B" and leave the adequacy determination to the buyer without guidance. The catalog must encode hazard-class metadata so that an AI agent can match the kit to the customer's hazard profile.

STOP THE BLEED — CAT Gen7, SOFTT-W, and Hemostatic Gauze

STOP THE BLEED is a national hemorrhage control initiative launched October 6, 2015 by the American College of Surgeons (ACS) with support from the White House and the Hartford Consensus group. The program trains lay responders in three steps: (1) apply direct pressure to bleeding wounds, (2) pack the wound with gauze and apply pressure to junctional wounds, (3) apply a tourniquet to life-threatening extremity bleeding. The initiative was modeled on military hemorrhage control protocols — specifically TCCC (Tactical Combat Casualty Care) — that reduced preventable hemorrhage deaths among US military personnel from approximately 21% to under 7% over 15 years of application.

CAT Gen7 (Combat Application Tourniquet, Generation 7)

The CAT Gen7 is a windlass-style tourniquet manufactured by North American Rescue under license from the COTCCC (Committee on Tactical Combat Casualty Care), which approves it as a primary extremity tourniquet for military and civilian use. Key characteristics relevant to workplace first aid:

• One-hand application: Designed to be self-applied to the upper arm with one hand, enabling self-rescue by the injured worker
• Windlass mechanism: Rod-and-strap system that can be tightened to complete arterial occlusion in 2–4 complete turns for most adult extremities
• Time notation window: Built-in white window to record tourniquet application time — critical for hospital handoff (tourniquet time influences tissue viability decisions)
• COTCCC approval: Listed on the COTCCC Approved Devices List since Generation 1; Gen7 approval maintained as of the most recent review
• Shelf life: 5 years sealed in original packaging; inspect annually when in service

SOFTT-W (Special Operations Forces Tactical Tourniquet-Wide)

The SOFTT-W, manufactured by Tactical Medical Solutions, is a COTCCC-approved alternative to the CAT. The SOFTT-W uses a wider cuff (1.5 in) and a proprietary buckle-and-windlass design. Primary differences from the CAT Gen7:

• Wider cuff: Distributes force over a larger surface area — relevant for extremities with heavy soft tissue (large-thigh application) or for lower-limb amputations where the broader band reduces localized tissue damage
• Lower profile: Thinner when folded — relevant for carrying in vest pockets or compact first aid pouches
• More difficult one-hand application: The buckle mechanism is generally considered more challenging for one-handed self-application compared to the CAT Gen7 — relevant for workplace kits where co-worker application is the primary use case

For most workplace first aid kits where rescuer-to-victim application is the primary scenario, either the CAT Gen7 or SOFTT-W is appropriate. For kits intended to include self-application capability (lone worker, remote operations), the CAT Gen7 is generally preferred due to its simpler one-hand application protocol.

Hemostatic Gauze — QuikClot, Celox, HemCon

Extremity tourniquets address limb hemorrhage only. Wounds to junctional anatomy — the axilla (armpit), groin, neck, and shoulder — are not amenable to tourniquet application because no stable compression point exists proximal to the wound. These wounds require wound packing with hemostatic gauze: gauze impregnated with a hemostatic agent that accelerates clot formation at the wound surface.

The three primary civilian hemostatic gauzes are:

For workplace first aid kits in construction, manufacturing, and extraction where the injury profile includes potential groin, axilla, or neck penetrating trauma (saw injury, rigging struck-by, machinery entanglement), hemostatic gauze provides the treatment capability for wounds that tourniquets cannot address. A complete hemorrhage control supplement to a Class B kit for a high-hazard workplace includes: 1–2 CAT Gen7 or SOFTT-W tourniquets, 1 package of hemostatic gauze (QuikClot Combat Gauze or Celox Gauze), 1 pressure bandage (Israeli Bandage or similar), and nitrile gloves (2+ pairs).

JHA Documentation Template for First Aid Kit Adequacy

An employer documenting first aid kit adequacy under OSHA CPL 02-02-053 should produce a written record linking identified workplace hazards to first aid kit contents. The following structure satisfies the compliance documentation requirement and provides the hazard inputs needed for catalog AI routing.

Each row in the JHA corresponds to a first_aid_kit.hazard_application value that should be encoded in the Shopify product catalog for the kits selected to address that hazard class. A catalog AI receiving a query for "first aid kit for punch press shop, 15 employees" can only route correctly if the product metadata encodes hazard_application = 'heavy_manufacturing', includes_tourniquet = true, and osha_adequate = true for the Class B + hemorrhage kit — rather than routing the nearest Class B kit by person count alone.
