Electrical Exam Term
Lockout/Tagout (LOTO)
A safety procedure that ensures dangerous electrical equipment is properly shut off and cannot be started up again before maintenance or servicing work is completed.
Detailed Explanation
OSHA 29 CFR 1910.147 requires lockout/tagout procedures for any work on electrical systems. The procedure involves de-energizing equipment, applying a physical lock and warning tag to the disconnect, testing to verify the circuit is dead, and only then beginning work. Each worker must apply their own lock. This is one of the most critical safety practices for electrical workers.
