Valve Lockouts –

Designed to prevent fluid or gas valves from being opened while repair or maintenance is occurring. This could involve ball valves (handle you turn 90° to shut off) or gate valves (round knob). Ball valve lockouts are measured by the length of the handle. Gate valve lockouts are measured by the diameter of the knob.

Group Lock Box or Gang Box –

Commonly used to lock out very large pieces of equipment that have multiple work functions affecting the maintenance of the equipment. This box allows for each lockout point to be secured with just one designated lock. The accompanying keys are then placed in the box.

Each employee locks just one personal safety lock onto the box. The captured keys cannot be removed, or the equipment re-energized until all have removed their locks from the box.

OSHA Lockout Device Requirements

Lockout Devices must:

  • Be provided by the employer
  • Be standardized by size, shape or color
  • Be distinguishable from locks used for other purposes. Lockout locks should only be used for lockout.
  • Identify the individual who applied the lock (both tags and lock labels are acceptable for this purpose)
  • Be capable of withstanding the usage environment and must be strong enough to prevent removal except by using excessive force with special tools, such as bolt cutters.

Most importantly, whenever lockout devices are applied, they must remain under the exclusive control of the individual who attached them. No employee should be able to open a lock attached to someone else.
