Hydraulic Energy Source

Hydraulic energy must be controlled via a mechanical energy isolating device that physically prevents the transmission or release of energy. Hydraulic 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 systems may have accumulators or intensifiers that require specific practices to release pressure. Verifying the absence of hydraulic 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.
