Pneumatic Lockout

Isolate at the supply, then block the connection so nobody can reconnect: the Pneumatic Male Air Lockout plugs into the male quick-coupling and takes a padlock, so the tool or machine cannot be fed again. Bleed the line before work starts; trapped pressure is the usual cause of injury. Where the isolation point is a valve, use a ball valve lockout instead.

For lines that cannot be unplugged. The Pneumatic Air Isolation Box closes around the fitting or the shut-off valve and locks with several padlocks, so a group can isolate one air supply together and each person keeps their own key. It suits filter-regulator units, manifolds and machine inlets that stay connected during maintenance.

Close the cylinder valve and cover it: the Gas Cylinder Lockout, large fits over the valve and handwheel of standard industrial cylinders, and the Gas Cylinder Lockout, small suits smaller bottles. The cover locks with one padlock and stops the valve being opened while a line is open or a regulator is changed. It also makes an empty or off-limits cylinder obvious in the store.
