Description
This unit covers supervising work in confined space in resources and infrastructure industries. It includes: preparing for work; providing information; ensuring that the safety and health of personnel entering and working in a confined space is not affected; supervising entry and work; implementing emergency and rescue systems; and withdrawing from confined space and facilitate return to service.

4. Supervise entry and work in a confined space
  • 4.1. Allocate resources to confined space personnel for effective, safe performance of designated work
  • 4.2. Ensure that all personnel entering the confined space read, understand and sign the Confined Space Entry Permit and hot work permits
  • 4.3. Ensure that all personnel are clear on their work activities and responsibilities
  • 4.4. Brief and post confined space observers and sentries
  • 4.5. Check that required personal protective equipment is worn in accordance with site practices and manufacturers' instructions
  • 4.6. Ensure that communications systems are installed and maintained
  • 4.7. Monitor and evaluate the continued effectiveness of risk assessment processes and controls
  • 4.8. Test and maintain controls
  • 4.9. Ensure that work adheres to SOPs
5. Implement confined space emergency and rescue systems

  • 5.2. Identify and liaise with external Emergency Services agencies
  • 5.3. Implement site approved emergency procedures
  • 5.4. Ensure that personnel are trained in emergency procedures
  • 5.5. Keep and maintain emergency procedure training records
6. Withdraw from confined space and facilitate return to service
  • 6.1. Ensure that confined space work is completed to site requirements and all work-related materials and equipment removed from the confined space
  • 6.2. Ensure all Permits to Work are cleared and systems isolation devices removed
  • 6.3. Ensure that all personnel sign off the Confined Space Entry Permit
  • 6.4. Advise appropriate personnel that the confined space is clear for return to service
  • 6.5. Review the confined space safety management program
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. 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) may also be included.
Relevant compliance documentation
may include:
legislative, organisation and site requirements and procedures
manufacturer's guidelines and specifications
Australian standards
code of practice
Employment and workplace relations legislation
Equal Employment Opportunity and Disability Discrimination legislation
A confined spaces safety management program may typically cover:
roles and responsibilities according the legislation and identification and designation of areas of responsibility
hazard identification and risk management
specific strategies to ensure that training and information are delivered commensurate to the position and responsibility
procedures for safe working in confined spaces
system for use of confined spaces entry and hot work permits
record keeping in accordance with legislative requirements
resourcing of appropriate confined spaces safety training
Communications may include:
hand-held radio
telephone
mobile phone
hand signals
computer
verbal instructions
lights
Personal protective equipment may include:
face and eye protection;
head protection;
foot protection;
body protection;
hearing protection;
respiratory protection;
hand protection
harnesses and/or safety lines
The Hierarchy of Controls lists the control measures that should be implemented in priority order, including:
elimination
substitution
isolation
engineering controls
administrative controls
personal protective equipment

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competency in this unit must be relevant to worksite operations and satisfy all of the requirements of the performance criteria, required skills and knowledge and the range statement of this unit and include evidence of the following:
knowledge of the requirements, procedures and instructions for supervising work in confined spaces
implementation of appropriate procedures and techniques for the supervision of safe, effective and efficient work in confined spaces
working with others to plan, prepare and conduct work in confined spaces
provision of clear and timely instruction and supervision by the individual of those involved in working in confined spaces
evidence of the consistent successful supervision of work in confined spaces
Context of and specific resources for assessment
This unit must be assessed in the context of the work environment. Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills.
The assessment environment should not disadvantage the participant. For example, language, literacy and numeracy demands of assessment should not be greater than those required on the job.
Customisation of assessment and delivery environment to sensitively accommodate cultural diversity.
Aboriginal people and other people from a non English speaking background may have second language issues.
Assessment of this competency requires typical resources normally used in a resources and infrastructure sector environment. Selection and use of resources for particular worksites may differ due to the site circumstances.
Where applicable, physical resources should include equipment modified for people with disabilities.
Access must be provided to appropriate learning and/or assessment support when required.
Method of assessment
This unit may be assessed in a holistic way with other units of competency. The assessment strategy for this unit must verify required knowledge and skill and practical application using more than one of the following assessment methods:
written and/or oral assessment of the candidate's required knowledge
observed, documented and/or first hand testimonial evidence of the candidate's:
implementation of appropriate procedures and techniques for the safe, effective and efficient achievement of the required outcomes
consistently achieving the required outcomes
first hand testimonial evidence of the candidate's:
working with others to plan, prepare and conduct work in confined spaces
provision of clear and timely instruction and supervision by the individual of those involved in working in confined spaces
Guidance information for assessment
Consult the SkillsDMC User Guide for further information on assessment including access and equity issues.
