Abstract
A one piece valve lockout device for use with a quarter turn, rotary selector valve that is closed at the one-eighth turn position and is mounted on a common assembly with a manually operated pump. The device includes parallel ears configured in a U shape, used to secure the device to the pumping assembly. The ears are oriented 45 degrees from a locking arm. The locking arm has two parallel plates extending downward around a valve handle. The parallel plates have pairs of aligned holes in which a padlock can be inserted, preventing unauthorized removal of the device.
