Valve Handle Lockouts

Stop gas and fluid valve handles from opening and closing during maintenance. Valve lockouts like these help you comply with OSHA 29 CFR 1910.147, which requires handles on pneumatic and hydraulic systems to be locked out during maintenance to prevent injuries.

Slide-on lockouts fit onto the valve handle; the valve body prevents the handle from turning. All of these lockouts work on closed handles, but some also work on open ones. Style C lockouts have a cylinder and end cap that you place over your valve.

Clamp-on lockouts adjust to fit a range of handle sizes. Style F lockouts wedge compression handles, preventing them from being squeezed to stop your valve from operating.

Hinged lockouts secure the valve handle in any position. They have a one-piece design that stays together for easy storage.
