Lockout/Tagout is the name for a protection system used to prevent unintentional exposure to hazards associated with specific types of machinery and equipment.
Lockout/Tagout (LOTO) devices are used to prevent equipment from being accidentally powered on during maintenance and repairs in order to protect workers. They're commonly used on machinery, electrical equipment, vehicles, plumbing systems and other mechanical devices.
Failure to correctly follow LOTO procedures or use the equipment properly is one of the most common causes of workplace electrical accidents.
Some LOTO devices fit specific equipment such as steering wheels. Electrical lockouts keep circuit breakers, plugs and switches secured. Flange lockout devices conceal flange bolts to prevent access during pipeline maintenance.
Choosing the right type of lockout device starts by knowing the many types available so you can choose the most effective option for your needs. Here's a sampling of some common types of LOTO devices and their purposes.
Lockout padlocks are used to add extra security at a lockout point. These can be keyed alike or different depending on the application. They are in multiple colors, though there is no industry-wide standard for how the colors are used. Lockout padlocks are used to lock LOTO devices.
Electrical lockouts are used to protect workers from accidental exposure to hazardous electrical energy releases.
Steering wheel lockouts attach to a vehicle's steering wheel to warn users that a vehicle is not in operation or is currently being serviced and should not be used.
These covers do not actually disable a steering wheel, though many have a grommet hole that allows a padlock to be added.
Lockout hasps are used when multiple people are servicing the same equipment.
These hold several padlocks at one time, adding an extra level of safety by requiring multiple authorizations for access to one locked-down device.
Lockout stations and kits are easy to identify and store a variety of LOTO devices.
These stations make it convenient for workers to find the LOTO supplies they need in one location. They can be stationary or portable for job sites.
