Description
This unit covers escaping from hazardous situation unaided in the underground mining industries. It includes: assessing and withdrawing from hazardous situations; evacuating to fresh air; reporting and debriefing.
Notes
Elements and Performance Criteria
1. Assess and withdraw from hazardous situation
- 1.1. Access, interpret and apply compliance documentation relevant to escaping from hazardous situation unaided
- 1.2. Interpret alarms and indicators to determine the type, cause and severity of the hazard
- 1.3. Assess threat/danger and decide on the safest escape option and escape route in liaison with other workers in the vicinity. Notify appropriate personnel as per site requirements
- 1.4. If safe, withdraw from hazardous situation by proceeding to selected escape route
- 1.5. Don self-contained self rescuer and/or other recommended personal protective equipment according to manufacturer's instructions and/or site requirements
- 1.6. Evaluate the need to barricade-in and wait for external aided rescue
2. Evacuate to fresh air
- 2.1. Evacuate from hazardous situation by the established or alternative escape route. Notify appropriate personnel as per site requirements, if possible
- 2.2. Follow escape route markers and guidance system to navigate escape route at optimum rate of travel
- 2.3. Continuously monitor and observe the mine atmosphere and mine environmental conditions and respond to adverse conditions
- 2.4. If irrespirable atmosphere continues, locate and access self rescuer/breathing apparatus caches and utilise according to site requirements
- 2.5. Evaluate the need for, and locate and retreat to a place of safety or build barricade/s for protection from adverse conditions
- 2.6. Monitor air/oxygen usage and adjust rate of travel where necessary, and ensure efficient changeover of self rescuer/breathing apparatus within determined operational timeframes
3. Report and debrief
- 3.1. Provide details of escape to relevant personnel in accordance with legislation and site requirements
- 3.2. Evaluate the need for voluntary counselling

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 escaping from hazardous situation unaided
implementation of requirements, procedures and techniques for the safe, effective and efficient completion of escape from hazardous situation unaided
working with others to undertake and complete escape from hazardous situation unaided that meets all of the required outcomes
consistent timely completion of procedures for escaping from hazardous situation unaided that safely, effectively and efficiently meets the required outcomes
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 the work environment. Selection and use of resources for particular worksites may differ due to 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 requirement, procedures and techniques for the safe, effective and efficient achievement of required outcomes
consistently achieving the required outcomes
first hand testimonial evidence of the candidate's:
working with others to undertake and complete escape from hazardous situation unaided
Guidance information for assessment
