Frequently Asked Questions
Can one employee lock out equipment for the whole crew?
Not by itself if multiple workers are exposed. Each exposed worker needs personal protection, typically by applying their own lock to a hasp or approved group-lockout device.
What is the main message supervisors should reinforce?
If your work puts you in the hazard zone, your protection must be under your control. No one should borrow another person’s lock or assume equipment is already safe.
What standard covers this rule?
OSHA addresses this in 29 CFR 1910.147 for general industry, with related construction requirements in 29 CFR 1926.417 where applicable. ANSI/ASSE Z244.1 is a recognized consensus standard often used to support program design.
