This unit covers competence associated with the operation and maintenance of breathing apparatus equipment in an irrespirable atmosphere. This competency applies to operators who are required to wear breathing apparatus for part of their job - because they are working in a confined space, with hazardous gases/vapours, in an anoxic atmosphere or for other applications requiring the wearing of breathing apparatus.
They may also be required to wear it in emergency situations, however this is not the prime focus of this unit, and so makes this unit different from PUAFIR207A Operate breathing apparatus open circuit, as it has no prerequisite and is much broader in its application.
