Push Button Safety Covers
Lock out the on/off or emergency-stop buttons on machinery to prevent accidental or unauthorized startups, such as during maintenance. These lockout covers secure with padlocks and indicate to workers that a button is off for safety. By disabling push buttons, these safety covers also help you comply with OSHA 29 CFR 1910.147 lockout requirements for maintaining machinery.
Removable safety covers twist on and off a mounted base that fits around a button. Use the included colored labels to identify the buttons. Red covers are easy to see when installed.
Hinged safety covers have a door that flips shut. They mount permanently and encase two button sizes—22 mm or 30 mm. Snap off the tabs around the mounting hole to fit 30 mm buttons.
Crossbar safety covers have a bar that locks a button in the off position.

Two-Hand Safety Switches
It takes two hands to activate these switches, minimizing the risk of accidental equipment start up. A complete system requires two switches, one safety relay, and two outlet boxes.
Switch guards protect switches against damage and accidental activation. Use one guard per switch.
