OSHA Evacuation Requirements: An Operational Overview
Not legal advice. Always consult qualified counsel and your safety officers for your jurisdiction and site.
What employers are expected to plan for
OSHA emergency action standards (for example 29 CFR 1910.38 for many employers) expect a plan that covers evacuation, reporting, and accounting for employees — the exact wording belongs in your program documents.
Practically, "accounting" means you can show who was still missing after you reach a safe assembly point — not that you guessed well.
How software helps (without replacing judgment)
Digital mustering tools timestamp check-ins at assembly areas. PingIn supports that workflow on Enterprise — see emergency mustering.
