The MSMWHS217 Gas Test Atmospheres unit is about testing the working atmosphere to determine if it is safe for the proposed work. Testing involves the use of electronic test apparatus.
In a typical scenario an individual may be required to carry out gas testing of an atmosphere prior to entering a specific area or workspace. The competency requires the person to interpret readings and take actions based on the interpretation.
This unit is modelled on the Public Safety unit PUAFIR307A Monitor hazardous atmospheres, but does not have the prerequisites, which are not required in the industrial context. The unit is more focused on the needs of that sector and has some wording changes.
Prepare for gas testing
Determine type of gas/atmosphere to be tested.
Select and calibrate equipment in accordance with procedures.
Determine gas testing regime/sampling pattern required.
Identify hazards from possible atmosphere contaminants.
Implement hazard control measures, including use of appropriate personal protective equipment.
Test gas
Use gas testing equipment to test gas as required.
Interpret and report readings.
Monitor gas on an ongoing basis as required.
Take required action(s) if readings are unacceptable
Maintain equipment
Clean and maintain gas testing equipment in accordance with procedures.
Inspect and fault find monitoring equipment in accordance with procedures.
Return gas testing equipment to required location and in required condition.
Maintain records of tests and results in accordance with procedures.
This describes the essential skills and knowledge and their level required for this unit.
As may be relevant to the plant/site/process, knowledge of the following may be required:
Underpinning skills could include interpretation and communication of results of sampling.
Language, literacy and numeracy requirements
This unit requires the ability to read and interpret a meter and then communicate the conclusions.
Writing is required to the level of completing required workplace reports/forms.
Numeracy read the instrument and interpret the results as being safe/not safe and so determine the required actions.
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:
Consistent performance should be demonstrated. For example, look to see that:
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:
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.
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
Workplace atmospheres may
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:
Problems
‘Respond to routine problems’ means ‘apply known solutions to a limited range of predictable problems’.
