A contractor working on-site needs to perform maintenance on electrical equipment. Regarding LOTO, what must the host employer do?
Answer: Inform the contractor of the facility's LOTO program and any unique hazards
The host employer must inform outside contractors of the facility's lockout/tagout program and any unique energy control hazards to ensure contractor safety.
What is the purpose of a 'try-out' step during the lockout/tagout procedure?
Answer: To verify de-energization by attempting to start or operate the equipment
The try-out step verifies that the equipment is de-energized by attempting to operate it after locks are applied, confirming all energy sources have been successfully isolated.
An employee finds an unattended lockout device on a machine. The employee does not know who applied it. What should be done?
Answer: Contact the supervisor to determine the lock's owner before removing it
An unattended or abandoned lock must never be removed without supervisor authorization and following the facility's procedure for removing a lockout applied by an absent employee.
For complex equipment with multiple energy sources, what document is typically required before LOTO work begins?
Answer: A written energy control procedure specific to the equipment
OSHA requires a written energy control procedure for equipment with multiple energy sources that clearly details the steps for isolating and controlling each energy source.
Which of the following is classified as an energy-isolating device under OSHA's LOTO standard?
Answer: A manually operated disconnect switch
A manually operated disconnect switch is an energy-isolating device because it physically separates the energy source from the equipment and can be locked in the open position.
Under NFPA 70E, what is the primary purpose of establishing an electrically safe work condition before non-electrical maintenance tasks?
Answer: To eliminate the risk of unexpected energization, startup, or release of stored electrical energy
Establishing an electrically safe work condition eliminates the risk of unexpected energization or release of stored energy, protecting workers from electrical hazards during maintenance.
When removing lockout devices at the end of a job, who is the ONLY person authorized to remove their own lock?
Answer: The authorized employee who applied the lock
Only the authorized employee who applied a lockout device is permitted to remove it, ensuring personal accountability and preventing re-energization while others may still be at risk.
