A pneumatic lockout/tagout utilizes which component to prevent use?

Lockable valve
Switch
Pressure relieving cylinder
Saddle cut switch

The correct answer is: Lockable valve

A pneumatic lockout/tagout system is designed specifically to ensure that machinery or systems cannot be accidentally energized or operated while maintenance or repairs are being performed. A lockable valve serves as a physical barrier to control the flow of air or fluid within a pneumatic system. When a lockable valve is in the closed position and appropriately locked, it effectively prevents the system from being pressurized, thereby ensuring that no unintended operation occurs. Locking devices enhance safety by allowing maintenance personnel to apply their own locks and tags to a valve, indicating that they are working on the machinery and that it should not be operated. By utilizing a lockable valve, it directly contributes to a safe working environment, reducing the risk of accidental start-up or release of energy. This makes it a fundamental component in facilitating safe work practices in accordance with standard safety protocols.
