Frequently Asked Questions
Does OSHA require a specific list of items in a construction first aid kit?
No. OSHA requires first aid supplies to be readily available and suitable for the jobsite, but it does not provide one universal construction packing list for every project.
What standard should I use to build a first aid kit for a construction site?
ANSI/ISEA Z308.1 is a common baseline for workplace first aid kits. On construction sites, employers should add supplies based on the actual hazards, crew size, and access to medical care.
How often do construction first aid kits need to be inspected?
OSHA does not set one fixed inspection interval for every construction kit. A practical approach is to inspect on a routine schedule, after use, and whenever site conditions or work phases change.
Where should first aid kits be kept on a construction site?
They should be in clearly marked, easy-to-reach locations near active work areas. Large, multi-level, or spread-out projects often need multiple kits, including mobile or vehicle-based kits.
Is one first aid kit in the site trailer enough?
Usually not on an active construction project with dispersed crews. If workers have to travel too far or cross the site to reach supplies, access is not truly quick or practical.
