Steam Energy Sources

Steam Energy Source

Definition of Steam Energy

Steam energy pertains to the power related to steam and its presence on the equipment. The presence of steam typically includes the need for a Dissipate Thermal condition. Dissipation of thermal energy is covered in the Stored Thermal Energy page.

Associated Steam Energy Hazards

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

Injuries associated with Steam energy generally consist of the following:

  • Eye injuries due to blown debris
  • Burns or suffocation

Proper Lockout/Tagout can virtually eliminate the risk involved with Steam energy.

Means of Steam Energy Isolation

Steam energy must be controlled via a mechanical energy isolating device that physically prevents the transmission or release of the steam. Plant-specific handling instructions are often in place. Be aware of any special handling procedures or PPE that may be required. Details covering stored steam energy are available at the Stored Steam Energy page.

Verifying Absence of Steam Energy

Verifying the absence of steam 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 Steam Energy Isolation Devices

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

  • Gate Valves
  • Ball Valves
  • Butterfly Valves
  • Flanges that allow a blank to be inserted

Typical Steam Energy Lockout Devices

Steam 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 steam energy lockout devices are outlined in the Valve and Pneumatic page.
