Elements and Performance Criteria

RANGE STATEMENT
The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.
Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.
Context
Working environment may be hazardous, unpredictable, subject to time pressure, chaotic and expose responders to risk, on land or water, by day or night.
Safety information and procedures must include relevant legislation, Australian Standards, codes of practice, manufacturer instructions and organisational procedures.
Situations include
confined spaces
enclosed and partially enclosed spaces
storage tanks, silos, pits, pipes, shafts, ducts, transport vehicles and ships
testing as part of issuing a work permit
monitoring as part of working under a work permit
open areas
holding the gas tester by hand
lowering the gas tester into a space, eg on a line.
Workplace atmospheres may
include visible and invisible hazards
include hazardous surfaces
range from safe to unsafe.
Procedures
All operations are performed in accordance with procedures.
Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards.
All operations to which this unit applies are subject to stringent Health, Safety and Environment requirements, which may be imposed through State or Federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and HSE requirements, the HSE requirements take precedence.
Tools and equipment
This competency includes use of equipment and tools such as:
portable instruments
radiation detectors
sampling tubes and pumps
oxygen level meter
carbon monoxide detector
combustible gas detectors.
Problems
'Respond to routine problems' means 'apply known solutions to a limited range of predictable problems'.

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, required skills and knowledge, the Range Statement and the Assessment Guidelines for this Training Package.
Overview of assessment
A holistic approach should be taken to the assessment.
Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:
apply personal safety principles
interpret atmospheric conditions using atmospheric monitoring equipment
recommend appropriate action
maintain monitoring equipment.
Consistent performance should be demonstrated. For example, look to see that:
gathered evidence covers a range of variables, all using different types of monitoring equipment.
Assessment method and context
Assessment will occur using industrial test equipment on an industrial site/plant and will be undertaken in a work-like environment.
Competence in this unit may be assessed:
through written assignments
by a demonstration activity using workplaces/atmospheres with detectable but safe levels of contaminants should be used
by using a suitable simulation and/or a range of case studies/scenarios
through a combination of these techniques.
In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.
Specific resources for assessment
This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
