Pneumatic Energy Source

Pneumatic energy must be controlled via a mechanical energy isolating device that physically prevents the transmission or release of energy. Pneumatic energy lockout devices use positive means such as a lock and key to keep the associated energy isolation device in the safe position and prevent equipment energization. Some pneumatic isolation devices automatically vent air pressure when lockout occurs, others require manual venting. Verifying the absence of pneumatic energy after performing lockout/tagout can be done by attempting to operate the associated components and by observing the associated gages to ensure they indicate 0 (zero) pressure.
