Quick Answer
Put first aid kit signs where a worker can see them from normal approach paths and follow them to an actual, accessible kit. Signs should identify the kit location, not point toward a locked room, an empty cabinet, or a route blocked by stored materials. OSHA requires first aid supplies to be readily available, but its general first aid rule does not impose one universal sign at every kit.
Who This Guide Is For
This guide is for people setting up or checking first aid locations in shops, warehouses, offices, and multi-area facilities. It is educational, not a substitute for a site-specific emergency plan, applicable state or local rules, or professional safety advice.
Walk the Route, Not Just the Wall
A sign directly above a cabinet is useful only after someone reaches that cabinet. During a minor injury, a coworker may start from a loading dock, aisle, break room, or far corner of the building. Walk those routes and ask a simple question: could a person unfamiliar with the site find the supplies without stopping to ask?
Start at normal entrances to each work area. Look along the line of sight, then turn every corner on the route to the kit. A direction sign may be more useful at a decision point than another label on the cabinet itself. Avoid placing a sign behind an open door, high shelving, seasonal displays, or equipment that moves during the shift.
The final marker should identify the actual cabinet or station. Keep the route clear, the cabinet accessible, and the supplies stocked. A bright sign cannot compensate for missing dressings or a key held by one absent supervisor.
A Placement Checklist
- Location: Is the kit near the work it serves, or does the route require a long detour? Larger or separated workplaces may need multiple supply locations.
- Visibility: Can people see the sign at the relevant approach distance and lighting conditions? Test from the real aisle, not only directly in front of the wall.
- Direction: At intersections or around corners, does a directional marker lead to the next visible marker or to the kit?
- Access: Can workers reach the kit during every operating shift? Check doors, locks, stored pallets, and after-hours arrangements.
- Consistency: Use the same symbol and naming convention throughout the site. If the station moves, update every directional sign that points to it.
- Condition: Replace damaged, obscured, or outdated signs as part of routine inspections.
- Contents: Check supplies and expiration dates using a first aid kit inspection checklist.
For multi-floor buildings, check routes from stairs and elevators on each floor. For separate buildings or outdoor work areas, inspect the path in the conditions crews actually face. A map at the entry can help, but it should not be the only clue once someone is moving through the facility.
What OSHA Does and Does Not Say
OSHA's general industry first aid rule, 29 CFR 1910.151, requires adequate first aid supplies to be readily available. Its guidance discusses additional kits for larger facilities or where work areas are widely separated. These are reasons to assess access and placement, not a blanket federal requirement to post a specific first aid sign at every cabinet.
When safety instruction signs are used, OSHA's sign rules address their design and application. Check which requirements apply to the specific workplace and sign. Other industries, state plans, local rules, or employer procedures may add requirements. Do not use a sign as proof that the underlying supplies, training, or response plan are adequate.
Keep Signs and Kits in the Same Inspection Loop
Assign one owner to walk the routes at a regular interval and after a layout change. Verify the sign still points to the current kit, that the cabinet opens, and that the stock matches the workplace's needs. Document the correction when a sign is moved or a kit is relocated.
A useful test is to ask a new employee to find the nearest kit from their assigned station. If they hesitate at a doorway or follow a sign to a different room, the wayfinding needs work. Repeat the test after racks, production lines, or room names change.
Frequently Asked Questions
Are first aid kit signs required by OSHA?
OSHA's general first aid provision requires supplies to be readily available; it does not set a universal first-aid-sign count or placement rule. Check any other applicable rules and your employer's emergency procedures.
Should a sign go above every kit?
A clear cabinet marker helps, but the more important question is whether someone can find that cabinet from the work areas it serves. Add directional signs at decision points when needed.
Is one central kit enough for a large facility?
Not necessarily. Consider travel time, separated work areas, shifts, and the site's hazards. OSHA guidance notes that multiple kits may be appropriate for large workplaces or widely separated areas.
