OUT-OF-SERVICE PROTECTION

Before any repair is to be performed on a piece of electrical equipment, be absolutely certain the source of electricity is open and tagged or locked out of service. Whenever you leave your job for any reason or whenever the job cannot be completed the same day. be sure the source of electricity is still open or disconnected when you return to continue the work. Seabees have died because they did not follow proper tag and lock-out procedures. These procedures are a must. It takes time to do it, but it is worth your life.
