Lock Out/Tag Out: Control of Hazardous Energy Course Overview
Lockout/Tagout violations consistently rank among OSHA’s Top 10 Most Serious and Most Cited Violations, causing preventable workplace injuries, deaths, and lost work time annually. Workers performing maintenance or servicing machinery face exposure to unexpected equipment startup, electrical shock, crushing injuries, amputations, and burns from stored energy release. Without proper training on controlling hazardous energy, workers may attempt to service equipment that appears off but remains dangerous due to residual electrical charge, pressurized fluids, hydraulic systems, or gravity-stored potential energy.
This course covers OSHA’s Control of Hazardous Energy standard (29 CFR 1910.147) for employees performing maintenance and repair work. Employees learn common types of hazardous energy (electrical, mechanical, hydraulic, pneumatic, chemical, thermal, gravitational), components of an employer’s energy control program, the six critical steps of lockout/tagout procedures, group LOTO protocols and shift change responsibilities, lock and tag requirements, and the distinct roles of Authorized Employees, Affected Employees, and Other Employees as defined by OSHA.
