OSHA wants to hear from employers about how they’ve been using control circuit-type devices to isolate energy and about evolving technology for robotics.
The information request is for a possible update of the agency’s Control of Hazardous Energy Lockout/Tagout (LOTO) standard.
In terms of the control circuit device use, OSHA wants details about the types of circuitry and safety procedures being used; limitations of their use, to determine under what other conditions control circuit-type devices could be used safely; new risks of worker exposure to hazardous energy as a result of increased interaction with robots; and whether the agency should consider changes to the LOTO standard that would address these new risks.
The current LOTO standard, published in 1989, requires that all sources of energy be controlled during servicing and maintenance of machines and equipment using an energy-isolating device. The standard specifies that control circuit devices cannot be used as energy-isolating devices, but the agency recognizes recent technological advances may have improved the safety of control circuit-type devices.
