What are the two types of energy control devices used in lockout/tagout?

The correct response identifies the two primary types of energy control devices used in the lockout/tagout (LOTO) procedure: lockout devices and tagout devices.

Lockout devices are physical devices that secure the energy-isolating mechanism of equipment in a safe position, ensuring that the equipment cannot be turned on or released during maintenance activities. Examples of lockout devices include padlocks, lockable switch covers, and hasps. These devices provide a strong visual indication and physical barrier, effectively preventing accidental energization.

Tagout devices, on the other hand, are used to indicate that a piece of equipment is being serviced and should not be operated. They serve as a warning to other workers and provide essential information about why the equipment is locked out. Tagout devices are usually tags that include information like the name of the person performing the maintenance and the reason for the lockout.

Both types of devices are crucial to achieving effective energy control, preventing the unexpected release of hazardous energy during service or maintenance work, and ensuring the safety of workers. The proper application of lockout/tagout devices is a key component of OSHA’s regulations for protecting workers from the hazards associated with potentially hazardous energy.
