LOCKOUT TAGOUT (LOTO)

Explore electrical energy as a hazardous workplace energy source, its dangers such as electrocution and arc flash, and the lockout tagout procedures that prevent accidents.

Learn how lockout tagout prevents hazards from mechanical energy by de-energizing machines during maintenance and addressing residual motion, springs, gears, and moving parts that cause crushing, pinching, or injuries.

Explore hydraulic energy and its hazards in forklifts, injection molding machines, and hydraulic presses; learn how pressure release and leaks can cause injuries, and how safety measures prevent them.

Examine how pneumatic energy is stored in compressed air or gas systems and the hazards of sudden pressure release, and learn to depressurize safely before maintenance.

Explore thermal energy hazards, including burns from hot surfaces and frostbite from cryogenic tanks, and how lockout tagout and protective gear prevent injuries.

Identify chemical energy hazards in flammable, toxic, and reactive substances in pipelines, tanks, and equipment, and apply handling, personal protective equipment, and pressure release to prevent explosions and toxic exposure.

Explore the devices used in lockout tagout to isolate energy sources, including padlocks, multi-lock systems for group LOTO, lockout tags, circuit breaker and wall switch lockouts, and plug lockouts.

Learn the three LOTO employee classifications—authorized, affected, and other employees. The lecture details who identifies hazardous energy, applies locks and tags, isolates energy sources, verifies zero energy, and documents procedures.

Identify energy sources and inform affected workers; shutdown equipment; isolate energy sources; apply lockout tagout devices; release energy; verify isolation; perform maintenance; remove tools, workers, and the lockout tagout system.

Identify primary and secondary energy sources, electrical, mechanical, hydraulic, pneumatic, gravitational, and backups, and assess hazards before isolating with energy isolation devices, then notify employees and lock out for maintenance.

Shut down the equipment by following the normal stopping procedure and the manufacturer’s shutdown method, ensuring all moving parts fully stop before isolating energy sources.

Isolate energy sources by disconnecting electrical, hydraulic, and pneumatic supplies and blocking mechanical movement, then apply lockout devices with individual locks and tags to prevent re-energization.

Release or block stored energy and verify isolation to prevent accidental movement during maintenance. Learn to discharge residual energy, apply blocking devices, and perform a try-out test to confirm de-energization.

Perform maintenance after verification, then remove lockout/tagout and restore power in a controlled, monitored sequence. Ensure all locks are removed only by their issuers, and complete a final inspection.

Assign a group lockout coordinator to oversee the process. Verify energy isolation, identify energy sources, prepare the plan, and ensure the group lockbox and personal locks are in place.
