This unit covers the competency required to use specific equipment to detect airborne contaminants, liquids and solids.

Unit details

Study level:
Vocational and further education (TAFE)
Unit code:


PUAFIR207B - Operate breathing apparatus open circuit


Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit's learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines. Students will be expected to demonstrate the following required skills: - analyse and communicate detection results; - don, operate in, decontaminate and remove personal protective clothing and equipment; - interpret safety and hazard information, and; - use detection equipment. Students will also be expected to demonstrate the following knowledge: - asphyixants, which may include simple and chemical, flammable gases and liquids, corrosive gases and liquids; - conditions under which atmospheres become hazardous; - dynamics of toxicity, corrosivity, flammability; - flammable range, upper and lower flammable limits; - legislation relevant to the organisation; - odour threshold, exposure standards (time weighted average, short term exposure limits, peak limitation values), immediately dangerous to life and health (IDLH), and may include acute exposure guideline levels (AEGL); - organisational policies and procedures; - physical chemistry concepts; - roles and responsibilities of agencies involved; - toxic effects on humans exposed to commonly encountered atmospheric contaminants such as reaction products or combustion products or variable oxygen concentrations, and; - units of measurement used to express concentration of atmospheric contaminants (mg/cubic m, ppm, %, v/v).
