In OSHA’s LOTO standard (1910.147), the agency included in their definition of a “lockout device” a “blank flange” and “bolted slip blind” when in fact, these devices are actually “energy isolation devices.” So why would OSHA consider these devices a “lockout device”?
NOTE: I am not in agreement with this and have never called a “blank flange” and “bolted slip blind” a “lockout device,” but rather an energy isolation devices. This may seem like semantics, but it is HUGE in the world of energy control!
