Application

This unit specifies the skills and knowledge required to install special hazard extinguishing systems, including decommissioning gaseous agent containers and actuation devices.
All technicians performing work described in this unit that involves the handling of prescribed ozone depleting substances (ODS) and synthetic greenhouse gases (SGG) extinguishing agents must hold an appropriate extinguishing agent handling licence (EAHL).
In some jurisdictions, this unit of competency may form part of accreditation, licensing, legislative, regulatory or certification requirements.

What You'll Learn

Assessment Requirements

Performance Evidence

To demonstrate competency, a candidate must meet the performance criteria for this unit by:
