First aid kits for construction sites answer to 29 CFR 1926.50, not the general industry rule: contents in a weatherproof container with sealed packages, checks before each job and weekly on the job, and a certified responder when no clinic is close. This guide decodes every paragraph and lays out the per-crew setup that satisfies them.

ANSI first aid kit Types I, II, III and IV rate the container - mounted indoor, portable indoor, water-resistant mobile, and waterproof harsh-environment - and are completely independent of Class A and B, which rate the contents. This guide decodes each type, maps types to workplaces, and shows how to read a listing that mixes both.
