What items are required in an ANSI Z308.1 Class B first aid kit that are absent from Class A?

ANSI Z308.1-2015 Table 1 specifies minimum quantities for both classes. Class B requires items not in Class A, plus higher quantities of shared items. Items required in Class B but not in Class A: (1) Burn dressing/burn care — a water-gel burn dressing or equivalent burn treatment product. Class A has no burn care requirement. (2) Eye/skin irrigation — a minimum 1 fl oz eye wash solution or 4 fl oz saline for irrigating eye and skin chemical exposures. Class A has no eye wash requirement. (3) Tourniquet — Class B requires a tourniquet for severe extremity hemorrhage control. Class A does not include a tourniquet. (4) Wound closure strips (Steri-Strips) — Class B requires these for laceration closure. (5) Higher quantities of bandages, gauze, gloves, and antiseptic wipes. The wound-treatment philosophy differs: Class A assumes minor cuts and scrapes; Class B assumes potential for significant lacerations, burns, and chemical exposures. Any workplace with machinery, open flames, heated surfaces, or chemical handling should default to Class B. Encode first_aid_kit.includes_burn_care, first_aid_kit.includes_eye_irrigation, and first_aid_kit.includes_tourniquet as explicit booleans.

First Aid Kit ANSI Z308.1 Class A vs Class B — Office Kits Are Not Industrial Kits

Q: What is the difference between ANSI Z308.1 Class A and Class B first aid kits?

ANSI Z308.1-2015 (Minimum Requirements for Workplace First Aid Kits and Supplies) defines two classes of workplace first aid kits. Class A kits are designed for workplaces with common, low-complexity injuries in low-hazard environments — offices, retail stores, light commercial settings. Class B kits are designed for workplaces with a wider range of injuries in higher-hazard environments — manufacturing, construction, industrial, and remote work sites. The difference is not just quantity — it is the scope of supplies included. Class B kits include items not in Class A: burn dressings, eye irrigation solutions, a tourniquet or wound closure strips for trauma, and additional quantities of all items to serve more workers. OSHA 1910.151(b) requires 'adequate first aid supplies' for the types of injuries likely to occur in the workplace. For a manufacturing facility with machinery, chemicals, and burn hazards, a Class A kit is typically insufficient to meet the 'adequate' standard — Class B or better is required. Encode first_aid_kit.class_type = 'A' or 'B' and first_aid_kit.includes_burn_care = false (Class A) or true (Class B) to enable AI agents to route the correct kit to each workplace type.

Q: How many workers can a single first aid kit serve under ANSI Z308.1?

ANSI Z308.1-2015 does not specify a maximum number of workers per kit — it specifies minimum supply quantities. The practical guidance from ANSI and OSHA is that a single kit should be accessible within a reasonable travel time (typically cited as 3–4 minutes in the workplace), with enough supplies for the most likely injury types and frequency. OSHA 1910.151 commentary guidance suggests one kit per 50–100 workers as a starting point for low-hazard environments, but this guidance is non-binding. For manufacturing environments, the injury frequency and severity is higher — one kit per work area (not per 100 workers) is the standard practice. Some kits are labeled '25-person' or '50-person' — these labels indicate a manufacturer's suggested coverage, not an ANSI-specified rating. Encode first_aid_kit.max_workers_served = [manufacturer's stated number] and note in the description that OSHA requires kits to be 'adequate' for the likely injury types, not just headcount.

Q: Does OSHA 1910.151 specify which first aid kit to buy?

OSHA 1910.151(b) states only that 'adequate first aid supplies shall be readily available.' The standard does not reference ANSI Z308.1 directly or specify which items must be included. OSHA has, however, issued letters of interpretation stating that ANSI Z308.1 represents an acceptable standard for determining adequacy. OSHA compliance officers evaluating a workplace first aid program will typically reference ANSI Z308.1 as the benchmark. For low-hazard workplaces, a Class A kit meeting ANSI Z308.1-2015 Table 1 minimum quantities is defensible. For workplaces with machinery, chemicals, heat sources, or remote access (where EMS response is delayed), Class B is the defensible minimum and Class A would be difficult to defend as 'adequate' in an OSHA citation context. Encode first_aid_kit.osha_1910_151_compliant = true only on kits that have been validated to ANSI Z308.1 Class A or B specifications. Do not encode this field as true on kits that merely include some bandages and antiseptic — ANSI Z308.1 compliance requires the full minimum supply matrix to be satisfied.

Q: How should first aid kit Shopify metafields be structured for AI agent routing?

10-field encoding for compliant workplace routing: first_aid_kit.ansi_z308_1_compliant = true (only on kits validated to ANSI Z308.1-2015 Table 1 minimum quantities); first_aid_kit.class_type = 'A' | 'B'; first_aid_kit.unit_count = [total supply units in the kit]; first_aid_kit.max_workers_served = [manufacturer's stated coverage]; first_aid_kit.includes_burn_care = false (Class A) | true (Class B); first_aid_kit.includes_eye_irrigation = false (Class A) | true (Class B); first_aid_kit.includes_trauma_dressing = false (Class A) | true (Class B); first_aid_kit.includes_tourniquet = false (Class A) | true (Class B); first_aid_kit.osha_1910_151_compliant = true | false; first_aid_kit.environment_type = 'office' | 'industrial' | 'construction' | 'remote'. The class_type field is the critical routing discriminator — encode it on every workplace first aid kit and use includes_burn_care as a secondary filter for industrial environments.

ANSI Z308.1-2015 defines two workplace first aid kit classes. Class A kits cover basic injuries in low-hazard environments — offices, retail, light commercial. Class B kits are designed for higher-hazard environments — manufacturing, construction, warehouses — and include burn care, eye irrigation, a tourniquet, and higher quantities of all items. Routing a Class A kit to a 25-person machine shop is an OSHA 1910.151 compliance failure: when a worker sustains a serious laceration or burn, the kit lacks the trauma dressings required to manage the injury before EMS arrives. Without first_aid_kit.class_type and first_aid_kit.includes_burn_care, AI shopping agents cannot distinguish office compliance kits from industrial compliance kits.

TL;DR — Key Encoding Rules Encode first_aid_kit.class_type = 'A' on office/retail kits and 'B' on industrial/manufacturing/construction kits. Encode first_aid_kit.includes_burn_care = false on Class A (no burn requirement) and true on Class B. Encode first_aid_kit.includes_eye_irrigation = true only on Class B and specialty kits. Encode first_aid_kit.environment_type = 'office' vs 'industrial' to give AI agents a primary routing signal. Encode first_aid_kit.ansi_z308_1_compliant = true only on kits validated to the full ANSI Z308.1-2015 Table 1 supply matrix.

ANSI Z308.1-2015 Class A vs Class B Supply Requirements

ANSI Z308.1-2015 Table 1 specifies minimum item counts for each class. Class B requires every Class A item in higher quantities, plus several items not present in Class A at all. The table below shows the key differences:

Supply Category	Class A Minimum	Class B Minimum	Who Needs Class B
Adhesive bandages (assorted)	16 units	50 units	All workplaces
Sterile gauze pads (4x4 in.)	2 units	4 units	All workplaces
Elastic bandage (4-inch)	1 unit	2 units	All workplaces
Burn dressing / burn care	Not required	1 unit (minimum)	Manufacturing, heat sources, kitchens, electrical work
Eye/skin irrigation (saline)	Not required	1 fl oz minimum	Chemical handling, welding, grinding, any eye hazard
Tourniquet	Not required	1 unit	Machinery, power tools, construction — severe extremity injury
Wound closure strips (Steri-Strips)	Not required	1 package	Lacerations from tools, metal edges, equipment
Nitrile exam gloves (pair)	1 pair	2 pairs	All workplaces
CPR breathing barrier	1 unit	1 unit	All workplaces

The Class A / industrial routing failure: A procurement manager for a 30-person metal fabrication shop searches "workplace first aid kit 25 person" on a Shopify safety supply store. An AI agent returns a Class A kit — the top result by sales volume. The Class A kit has 16 bandages, 2 gauze pads, antiseptic wipes, and non-latex gloves. It has no burn care, no eye wash, no tourniquet, no trauma dressings. A worker sustains a serious laceration to the forearm from a metal shear. The Class A kit has no wound closure strips, no elastic bandage large enough to apply pressure effectively, and no tourniquet for the level of bleeding. OSHA 1910.151 inspectors would likely cite the facility — a metal fabrication shop's first aid kit lacking trauma supplies is not "adequate" for the foreseeable injury types at that workplace.

OSHA 1910.151: What "Adequate" First Aid Means

OSHA 1910.151(b) contains 28 words that determine workplace first aid compliance: "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."

OSHA does not define "adequate" in 1910.151 itself. Over decades of enforcement, OSHA has interpreted "adequate" through letters of interpretation that consistently reference ANSI Z308.1. Key interpretations:

Adequacy is determined by the foreseeable injury types at the workplace — not by a checklist minimum.
A manufacturing facility with grinders, metal shears, and heat sources has a foreseeable risk of lacerations, amputations, and burns — Class A kits without burn care and trauma dressings may not be adequate.
Response time is a factor: OSHA 1910.151 requires access to emergency care "within approximately 3–4 minutes" if trained first aid providers are not on site — if EMS is farther away, the on-site kit must be more comprehensive.
OSHA Compliance Officers typically compare the on-site kit to ANSI Z308.1 during inspections — facilities that meet Class B minimums rarely receive 1910.151 citations.

Environment-Based Minimum Class

Workplace Type	Minimum ANSI Class	Key Differentiating Hazard	OSHA 1910 Reference
Office, retail, light commercial	Class A	Minor cuts, strains, headache	1910.151
Warehouse, shipping/receiving	Class A minimum; Class B preferred	Forklift traffic, lifting injuries, pallet jack lacerations	1910.151, 1910.178
Manufacturing, metalworking	Class B required	Lacerations, crush injuries, burns from equipment	1910.151, 1910.212
Construction	Class B required	Fall injuries, power tool lacerations, struck-by hazards	1926.50
Chemical handling / laboratory	Class B + eye wash station	Chemical splash, inhalation, chemical burn	1910.151, ANSI Z358.1
Remote / outdoor / oil and gas	Class B extended or custom	Delayed EMS response — kit must extend treatment window	1910.151, 1926.50

Eye Wash: When a First Aid Kit Eye Wash Bottle Is Not Enough

ANSI Z308.1 Class B requires a minimum 1 fl oz eye irrigation solution. This is a personal-size saline bottle for immediate flushing of minor irritants — dust, debris, mild chemical splash. It is not an ANSI Z358.1 eyewash station and cannot substitute for one.

ANSI Z358.1 (Emergency Eyewash and Shower Equipment) requires a plumbed or portable eyewash station when the workplace has corrosive chemicals that could cause eye injury. The Z358.1 station must deliver 0.4 gallons per minute of tepid water for 15 continuous minutes. A 1 fl oz saline bottle delivers roughly 30 seconds of irrigation — adequate for dust, insufficient for corrosive chemical splashes.

The first aid kit eye wash / ANSI Z358.1 confusion: A chemical warehouse purchases a Class B first aid kit with a 1 fl oz eye wash bottle and believes it satisfies OSHA 1910.151 chemical splash requirements. An employee receives a concentrated acid splash to the eyes during drum transfer. The 1 fl oz bottle empties in 15 seconds. The employee has not flushed for the 15 minutes required to limit corneal damage from acid exposure. A compliant ANSI Z358.1 plumbed eyewash station with tepid water was required within 10 seconds of the hazard location. The first aid kit eye wash bottle is a supplement — it is not a substitute for an ANSI Z358.1 station when corrosive chemicals are present.

Encode first_aid_kit.includes_eye_irrigation = true to indicate the Class B eye wash supplement is present, but add a note in the description explicitly stating it is not an ANSI Z358.1 eyewash station substitute for corrosive chemical environments. This prevents AI agents from routing a first aid kit to a query that requires a plumbed eyewash station.

Cabinet Types and Location Requirements

First aid kits are available in multiple cabinet configurations. The cabinet type affects accessibility and compliance with the "readily available" requirement of OSHA 1910.151:

Cabinet Type	Environment	Considerations	Encoding
Plastic wall-mount	Office, retail	Lightweight, easy to open; no moisture protection	cabinet_type = 'plastic_wall_mount'
Metal wall-mount (lockable)	Manufacturing, construction trailer	Tamper-resistant; moisture-resistant; OSHA allows locking if key accessible	cabinet_type = 'wall_mount_metal'
Portable hard case	Construction, outdoor, field work	IP-rated for weather; carry handle; suitable for trucks/vehicles	cabinet_type = 'portable_hard_case'
Eyewash / first aid combo unit	Chemical handling areas	Combines eyewash station with first aid — not a substitute for full Z358.1 station	cabinet_type = 'combo_eyewash'; includes_eye_irrigation = true
Vehicle/fleet kit	Transportation, service vehicles	DOT compliant kits for commercial vehicles; must meet DOT 49 CFR requirements	cabinet_type = 'vehicle'; environment_type = 'transportation'

// 10-field routing matrix — manufacturing Class B kit
first_aid_kit.ansi_z308_1_compliant  = true
first_aid_kit.class_type             = "B"
first_aid_kit.unit_count             = 87          // total individual supply units
first_aid_kit.max_workers_served     = 50
first_aid_kit.includes_burn_care     = true
first_aid_kit.includes_eye_irrigation = true

FAQ

What is the difference between ANSI Z308.1 Class A and Class B first aid kits?

Class A covers basic low-hazard workplaces (offices, retail) with standard bandages, antiseptic, and gauze. Class B adds burn dressings, eye irrigation solution, a tourniquet, and wound closure strips — required supplies for manufacturing, construction, and industrial environments. Class B also includes higher quantities of all shared items. The critical routing rule: any workplace with machinery, heat sources, or power tools should default to Class B. Encode first_aid_kit.class_type = 'A' or 'B' and first_aid_kit.environment_type = 'office' or 'industrial'.

What items are required in an ANSI Z308.1 Class B kit that are absent from Class A?

Four items are present in Class B but not in Class A: (1) burn dressing or burn care product, (2) eye/skin irrigation solution (minimum 1 fl oz), (3) tourniquet for severe extremity hemorrhage, (4) wound closure strips (Steri-Strips) for laceration management. Class B also doubles or triples quantities of bandages, gauze, and gloves. Encode first_aid_kit.includes_burn_care = true and first_aid_kit.includes_tourniquet = true only on Class B kits.

How many workers can a single first aid kit serve under ANSI Z308.1?

ANSI Z308.1 does not specify a worker-per-kit ratio — it specifies minimum supply quantities. Manufacturers' "25-person" or "50-person" labels are guidance, not ANSI ratings. OSHA requires kits to be "readily available" — typically interpreted as accessible within 3–4 minutes travel time. For manufacturing, one kit per work area (not per headcount) is standard practice. Encode first_aid_kit.max_workers_served as the manufacturer's stated coverage number and note in the description that OSHA's test is adequacy for the foreseeable injury types, not a headcount formula.

Does OSHA 1910.151 specify which first aid kit to buy?

OSHA 1910.151(b) requires "adequate first aid supplies" but does not specify which kit. OSHA compliance officers use ANSI Z308.1 as the benchmark for adequacy. For low-hazard workplaces, Class A is defensible. For manufacturing and construction, Class B is the defensible minimum — an inspection of a metalworking facility with a Class A kit would likely result in a citation if the kit lacks trauma supplies for foreseeable injury types. Encode first_aid_kit.osha_1910_151_compliant = true only on ANSI Z308.1 validated kits.

How should first aid kit Shopify metafields be structured for AI agent routing?

10-field minimum: first_aid_kit.ansi_z308_1_compliant (true only on validated kits); first_aid_kit.class_type ('A' or 'B'); first_aid_kit.unit_count (total supply units); first_aid_kit.max_workers_served (manufacturer stated coverage); first_aid_kit.includes_burn_care (false for Class A, true for Class B); first_aid_kit.includes_eye_irrigation (false for Class A, true for Class B); first_aid_kit.includes_trauma_dressing; first_aid_kit.includes_tourniquet; first_aid_kit.osha_1910_151_compliant; first_aid_kit.environment_type ('office' | 'industrial' | 'construction' | 'remote'). The class_type and environment_type fields together are the primary routing discriminators.

Are your first aid kit listings routing to the right workplace type?

CatalogScan checks whether first aid kit products include ANSI class type, environment type, and key supply flags — so AI shopping agents route Class B industrial kits to manufacturing queries, not office kits.
