Lockout device |
摘要 |
A locking device for use in connection with an energy controlling apparatus, such as a valve, or regulator, to prevent unauthorized persons from changing the position of a rotatable shaft of the apparatus that controls the amount of energy that flows through the apparatus. The locking device includes a handle used to manually set the position of the shaft. It also includes a gear that is rotatably mounted in the handle and is fixed to the shaft of the apparatus. A first locking mechanism carried by the handle mechanically and selectively couples the handle and the gear through a key access to the lock. A spring-biased ratchet mechanism may be provided to permit rotation of the shaft in one direction only. A personal locking mechanism with only a single key is selectively lockable to the handle so that in the locked position it prevents access to the first locking mechanism. |
