OSHA estimates that nearly 40 million maintenance workers could be exposed to unexpected machine start-ups or releases of hazardous energy while performing service or repair work on equipment. Developing and implementing a comprehensive lockout/tagout program has proven to be a safe and effective way for reducing these types of incidents.

Lockout/Tagout refers to the complete isolation of equipment from all energy sources during service or repair work. OSHA regulations 29 CFR 1910.147 and 1926.416 require the use of locks or tags as warning devices to ensure employees are not injured from accidental machine start-ups or the release of hazardous energy.

Utah State University Environmental Health and Safety Office conducts training and maintains the universities written lockout/tagout program. USU requires all employees who conduct service, maintenance or repair work on machines and equipment be trained in the recognition of hazardous energy sources and proper isolation (lockout/tagout) procedures.
