Chapter 8 Basic Electricity 8-26 Basic Electricity Lock out tag out should remove locks and tags is the person who put them there. To do a lock out tag to OSHA’s satisfaction, a lockout device and tag stating not to remove the lock should be placed over the circuit breaker, fuse box, or switch that will prevent a person from energizing the circuit. It is difficult to put a lock on a stair switch. As an alternative to locking out a piece of equipment, tag outs can be used if it will provide an equivalent level of safety. OSHA indicates that shutting off the equipment in two places will provide such equivalence. For example, if you shut off the circuit breaker and emergency switch at the top of the stairs and stick a note on both of them you have met the requirement. The following are some safety tips: • Shut off the power! • Stay focused! Even after turning off the power, work as if the wires are live. • Post a sign on the electric panel and remote switch so no one will turn on the power while you are working on the circuit. • Always check to be sure that the equipment being used is grounded. • Always use insulated tools and be sure the insulation is in good condition. Use electrical tape on wire nuts and connections for added protection. • Water on the floor is a good conductor— when working in wet areas, be sure to use protective equipment like rubber-soled shoes. • Do not overload electrical circuits. • Use extra caution with extension cords. Their insulation can be cut, and they can be overloaded leading to increased danger. • Inspect heating equipment before starting repair to be sure it is de-energized. • When inspecting a circuit, keep one hand in your pocket to prevent hand-tohand shock. Lock out tag out This procedure is used to be sure that no one turns on a switch and energizes electrical equipment while you are working on it. Use a tag or lock connected to the switch or circuit breaker to let other people know you turned it off on purpose and you want it to stay off. The only person who
