Types of Lockout Devices

Types of Lockout Devices

Lockout Padlocks

These are security padlocks used to lock LOTO devices in place . While they can be keyed alike, this should be avoided for safety reasons. If this is unavoidable their distribution should be limited among employees .

Circuit Breaker/Electrical Lockouts

These lockout devices are designed to prevent power from being restored or re-energized while equipment is being serviced. Once the power is shut off, the electrical lockout device fits over the switch and is often held in place by a padlock .

Valve Lockouts

This type of lockout device isolates energy in pipes by preventing valves from being opened which could affect any pipes or equipment that are being worked on downstream. The device is fixed over the closed valve and held in place by a padlock .

Cable Lockouts

For harder-to-lock devices such as handles and gate valves, cable lockouts provide safety and security during maintenance and repairs. The cable passes through the handles or valves and is pulled tight, then locked in place using a padlock .

Steering Wheel Lockouts

These devices attach to the steering wheel of a vehicle that is being maintained and repaired. They generally do not disable the steering wheel but rather display a warning not to use the vehicle while it is being worked on .

Flange Lockouts

These cover the bolts on pipeline flanges to prevent them from being opened while the pipeline is being worked on. A padlock holds the flange lockout in place to prevent it from being accidentally removed .

Gas Cylinder Lockouts

This type of lockout device covers valve handles and handwheels to prevent access to the main tank while work is ongoing. They are held in place with a padlock to protect them from any unauthorized access .

Pneumatic Lockouts

These lockout devices secure pneumatic fittings and regulators in place to prevent equipment from being energized. They are held in place by a padlock to ensure the pneumatic fittings do not connect to any pressurized air sources .

Lockout Hasps

Lockout hasps allow multiple workers to service the same equipment at one time. The hasp is applied to a lockout and has multiple shackle holes to allow other lockout devices to be attached. Once all lockout devices are removed the equipment can become operational again .

Group Lockout Boxes

These boxes are used to hold the keys used to lock padlocks in place that secure lockout devices during servicing. This provides a control point where each worker can select a padlock and key needed for maintenance or repair work .

Tagout Tags

When a lockout device is in use, these tags are used to alert workers that equipment is out of service. They are placed over the shackle of the padlock and are part of the OSHA standard for the Control of Hazardous Energy (Lockout/Tagout) .

Lockout Stations and Kits

Lockout stations allow you to store multiple lockout devices in one location for easy access. Stations are often wall-mounted or sit on the counter, while kits allow you to transport multiple devices to any location .
