A 37 year-old male elevator mechanic helper died when he was crushed in an escalator as he was performing maintenance. The victim had removed the escalator stairs and was standing inside the mechanism of the escalator when the power suddenly came on. The stairs began moving before the victim could get out and before the power could be turned off. There were no locks or tags on the controls that supply the electrical power to the escalator. The disconnect switch at the circuit panel that fed power to the elevator had not been locked and tagged out. The power came on when a co-worker dropped the electrical circuit box, triggering a relay that started the escalator's movement. There was a mechanical blocking device on the escalator to stop movement during maintenance, but it was not used. The CA/FACE investigator determined that, in order to prevent future occurrences, employers, as part of their Injury and Illness Prevention Program (IIPP) should: 1. Ensure employees follow company policy and procedures on lockout/tagout. 2. Ensure workers do not move electrical escalator equipment when all or part of someone is inside the escalator mechanism. 3. Ensure employees block mechanisms from moving prior to performing repairs or maintenance.
