This unit involves the skills and knowledge required to apply safety awareness and regulatory and industry standard requirements for ammonia refrigerant.

It includes safety and legal requirements when handling, using and storing ammonia refrigerant.

The skills and knowledgein this unit will be applied by those managing, supervising or working in or near a location that containsrefrigeration equipment usingammonia refrigerant. These could include managers, supervisors, maintenance staff, cleaners, employees and refrigeration and air conditioning technicians.

Dangerous goods and work health and safety (WHS)/occupational health and safety (OHS) legislative requirements apply to this unit.

ELEMENTS

PERFORMANCE CRITERIA

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions on at least two separate occasions and include:

applying relevant work health and safety (WHS)/occupational health and safety (WHS/OHS) requirements, workplace procedures and practices, including:

using risk control measures

following workplace procedures for hazard identification and risk control of ammonia refrigerant

applying safe working practices to safely handle and store ammonia refrigerant cylinders

applying working procedures and instructions as they apply to risk control measures

completing required documentation dealing with accidents and emergencies within the scope of responsibility

dealing with unplanned events/situations in accordance with workplace procedures in a manner that minimises risk to personnel and equipment

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must occur in workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated workplace operational situations that replicate workplace conditions.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Resources for assessment must include access to:

a range of relevant exercises, case studies and/or other simulations

relevant and appropriate materials, tools, equipment and personal protective equipment (PPE) currently used in industry

applicable documentation, including workplace procedures, emergency response plan, equipment specifications, regulations, codes of practice and operation manuals.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.

Range is restricted to essential operating conditions and any other variables essential to the work environment.

Non-essential conditions may be found in the UEE Electrotechnology Training Package Companion Volume Implementation Guide.

Applying safety awareness and legal requirements for ammonia refrigerant must include the following:
