Three mechanics are servicing the same conveyor under a group lockout. Per OSHA 1910.147, what is required of each mechanic?
Answer: Each authorized employee affixes a personal lock or tag to the group device
Group lockout requires each authorized employee to affix a personal lockout or tagout device to the group mechanism.
After isolating the electric motor on a hydraulic press, what must be done before work begins?
Answer: Relieve, disconnect, or restrain stored energy such as charged accumulators
OSHA requires that stored or residual energy, such as hydraulic accumulator pressure, be relieved, disconnected, restrained, or otherwise made safe.
After applying locks to a pump's disconnect, what is the correct next step before beginning maintenance?
Answer: Verify isolation by attempting to start the equipment, then return controls to off
Verification (try-out) confirms the machine is isolated and de-energized before work begins.
How often must the employer conduct periodic inspections of energy control procedures under 1910.147?
Answer: At least annually
Periodic inspections of each energy control procedure must be performed at least annually by an authorized employee other than the one using it.
A lockout must continue through a shift change. What does OSHA require?
Answer: Specific procedures for the orderly transfer of lockout protection between off-going and oncoming employees
Shift or personnel changes require specific procedures that ensure continuous lockout protection during the transfer.
A mechanic left the plant with their lock still on a machine. Under what condition may the employer remove it?
Answer: Only under a documented procedure that verifies the employee is not at the facility, attempts contact, and informs them before they resume work
1910.147(e)(3) allows removal by the employer only under a specific procedure including verification, contact attempts, and notification.
When is a tagout-only program permitted instead of lockout?
Answer: When the energy-isolating device is not capable of being locked out, or full employee protection is demonstrated
Tagout alone is acceptable when devices cannot accept a lock or when the employer demonstrates tagout gives protection equivalent to lockout.
