Key Interlocks and OSHA Requirements

OSHA's Regulations:
Standard Number 1910.147:
Standard Title: The Control of Hazardous Energy; Subpart Number: J.

In the aforementioned section, Osha describes its purpose:

"this section requires employers to establish a program to utilize procedures for affixing appropriate lockout devices or tagout devices to energy isolating devices, and to prevent unexpected energization, start up or release of stored energy in order to prevent injury to employees".

OSHA defines "Capable of being locked out":

an energy isolating device is capable of being locked out if it has a hasp or other means of attachment to which, or through which, a lock can be affixed, or it has a locking mechanism built into it. Furthermore OSHA defines a energy isolating device to be a device that physically prevents the transmission or release of energy, including but not limited to the following: a manually operated electrical circuit breaker, disconnect switch, a manually operated switch by which the conductors of a circuit can be disconnected from all ungrounded supply conductors and, in addition, no pole can be operated independently; a line valve; a block; and any similar device used to block or isolate energy.

Superior Key Interlocks are OSHA approved energy isolating lockout devices. A comprehensive key interlock system goes beyond the prescribed OSHA regulations by not only protecting individual pieces of equipment but also protecting the equipment from an overall systematic standpoint. Pictured below are several examples of our key interlocks used as lockout devices on several "energy isolating devices".
