Gas Energy Source

Definition of Gas Energy

Gas energy pertains to the power related to pressurized gases that are not pneumatic. The pressure can be relatively static (such as surge tanks or pressure tanks) or in motion though tubing or hoses. Gases may be needed for the equipment to perform a given function, for example, natural gas in heaters or nitrogen gas in an intensifier. In some cases the gases present are part of the process or final product. Systems with heaters may also require the dissipation of thermal energy covered in the Stored Thermal Energy page.

Associated Gas Energy Hazards

Per OSHA, there are hundreds of injuries annually due to improper handling of Gas energy.

Injuries associated with Gas energy generally consist of the following:

Proper lockout/tagout can virtually eliminate the risk involved with Gas energy.

Means of Gas Energy Isolation

Gas energy must be controlled via a mechanical energy isolating device that physically prevents the transmission or release of the gas. Depending upon the type of gas, some lockout devices automatically vent pressure when lockout occurs. Specific handling instructions may be required for some gases. Be aware of any special handling procedures or PPE that specific gases may require. Details covering stored gas energy are available at the Stored Gas Energy page.

Verifying Absence of Gas Energy

Verifying the absence of gas energy after performing lockout/tagout can be done by attempting to operate the associated components and by observing the level indicators and/or associated gages to ensure they indicate 0 pressure.

Typical Gas Energy Isolation Devices

Gas energy isolation devices may vary in design and configuration. Typical examples include:

Typical Gas Energy Lockout Devices

Gas 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. Typical gas energy lockout devices are outlined in the Valve and Pneumatic page.
