Task E‑18 Installs, tests, maintains, troubleshoots and repairs medical gas systems.

Task Descriptor

Medical gas piping systems are addressed separately due to their unique installation methods and applications. Additional certification may be required in certain jurisdictions. Medical gas systems are almost exclusively installed in health care facilities. Medical gas piping systems supply piped gases, such as oxygen, nitrous oxide, nitrogen, carbon dioxide and medical air, to various parts of the facility.

Steamfitters/Pipefitters are responsible for the installation and maintenance of piping, associated components and equipment for these systems. Maintenance is done on a regular schedule or on an emergency basis to ensure the integrity of the piping system. Steamfitters/Pipefitters are also responsible for diagnosing, locating and repairing or replacing equipment and material. Repairs are performed on an as-needed basis.

Task E‑20 Installs, and tests fire protection systems. (not common core)

Task Descriptor

Fire protection systems include fire sprinkler systems (wet, dry, pre-action and deluge), gaseous agents and wet and dry chemical agents. These systems protect buildings from the spread of fire.

In some jurisdiction in Canada, work on fire protection systems can only be performed by a certified and trained sprinkler system installer or apprentice. While steamfitters/pipefitters may possess similar skills required to install piping for fire protection systems, their installation and testing requires the application of specific codes and regulations.

Steamfitters/Pipefitters may do work associated with the installation and maintenance of piping, associated components and equipment for these systems. Maintenance is done on a regular schedule or on an emergency basis to ensure the integrity of the piping system. Steamfitters/Pipefitters may perform diagnosing, locating and repairing or replacing equipment and material. Repairs are performed on an as-needed basis.

Industry Expected Performance

At a journeyperson level of performance, all tasks must be done with minimal direction and supervision.
