OSHA requests information on possible updates to the lockout/tagout standard

The 1989 standard needs to updated to reflect the current use of automation and robotics equipment

By Wayne Labs, Senior Contributing Technical Editor

The U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) is requesting information on a possible update to the Control of Hazardous Energy (Lockout/Tagout (LOTO)) standard. The Agency is interested in comments on the use of control circuit-type devices to isolate energy, as well as the evolving technology for robotics.

OSHA is requesting information about how employers have been using control circuit devices, including information 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.

Comments must be submitted on or before August 18, 2019. Comments and materials may be submitted electronically at http://www.regulations.gov, the Federal e-Rulemaking Portal, or by facsimile or mail. See the Federal Register notice for submission details.

Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe and healthful workplaces for their employees. OSHA’s role is to help ensure these conditions for America’s working men and women by setting and enforcing standards, and providing training, education and assistance.
