Unit Descriptor

Unit descriptor 

This unit applies to a person who would typically be an incident team leader and who, following an incident, undertakes the inspection of the site and makes an initial assessment as to the immediate safety of the area.

Application of the Unit

Application of the unit 

The incident team leader typically responds to the incident coordinator, who may be stationed in the incident control centre.

In a typical scenario, following the occurrence of an incident the person would take action to ensure the immediate incident site is safe and take steps to maintain facility safety, record details of the scene and preserve it from contamination. The person may also be required to manage the scene pending the arrival of appropriate authority or company representatives as required by company procedures, legislation or regulations. Incident scenes may be the consequences of:

  • explosions
  • loss of containment of hazardous materials
  • environmental incidents
  • hydrocarbons fires or releases of noxious or toxic gasses

The person would:

  • ensure that the site is rendered safe and that access to the area is limited
  • take steps to ensure the site is preserved intact
  • ensure that site is isolated from ancillary processes to prevent secondary incidents
  • note or record all pertinent details
  • take statements or conduct interviews of witnesses

Generally the person would be part of a team during an investigation however may be required to take independent action. At all times they would be liaising and cooperating with other members of the organisation's incident management team.

5.6. Report problems outside area of responsibility to designated person

Required Skills and Knowledge


This describes the essential skills and knowledge and their level, required for this unit.

Required skills 

Competence includes the ability to isolate the causes of issues within the incident response system and to be able to distinguish between causes of issues indicated by:

  • materials being moved from the site without approval
  • vehicular or personal traffic contaminating the site
  • personnel being injured or contaminated on the site
  • loss of evidence from the site.

Required knowledge 

The knowledge referred to in the Evidence Guide for this unit includes:

  • methods of securing the site
  • techniques for removing survivors and non-survivors from the area
  • organisation requirements for taking witness details and information
  • regulatory requirements for taking witness details and information
  • legislative and organisation requirements relating to scene preservation
  • types of information which may assist in investigations.

Evidence Guide


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 the Training Package.

Overview of assessment 

Assessment for this unit of competency will be by way of simulation or under incident conditions. The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency. Assessment will occur over a range of situations which can include a variety of incident circumstances.

Simulations must, as closely as possible, approximate actual incident conditions and should be based on the actual facility. Assessments should include walk-throughs of the relevant competency components and may include the use of case studies/scenarios and role plays.

This unit of competency requires a significant body of knowledge which will be assessed through questioning and the use of 'what-if' scenarios both in the facility (during demonstration of normal operations and walk- throughs of abnormal operations) and off the site.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Competence must be demonstrated in the ability to correctly respond to incident situations and in implementing appropriate action. The emphasis should be on the ability to stay ahead of the problem rather than to have to take drastic action in order to recover the situation.

Consistent performance should be demonstrated. In particular look to see that:

  • incident responses are in accordance with company procedures
  • site is secured to preserve and maintain safety of personnel and restricted access
  • the safety and/or successful recovery of the person and others affected by the incident response is afforded priority in the actions taken
  • actions taken do not inhibit incident response effectiveness or further contribute to the incident
  • appropriate documentation including reports, journal entries, logs and/or clearances are completed in accordance with procedures

These assessment activities should include a range of problems, including new, unusual and improbable situations which may have been generated from past workplace incident history, incidents in similar workplaces around the world, hazard analysis activities and/or similar sources.

Context of and specific resources for assessment 

Assessment will require (1) access to an accurately simulated environment in the absence of an on-site incident environment, or (2) a suitable method of gathering evidence of responding ability over a range of situations. A bank of scenarios/case studies/what-ifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions.

Method of assessment 

In all workplace environments it may be appropriate to assess this unit concurrently with relevant units such as

Guidance information for assessment 

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.

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. Bold italicised wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.

Codes of practice / standards 

Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.


This unit of competency includes all such items of equipment and unit operations which form part of the incident response system. In your facility this may include (select relevant items):

  • note taking materials
  • standard forms
  • sketching materials
  • photographic equipment
  • taping or electronic videoing equipment
  • non sparking or radio transmission equipment (where safety permits)

Examples of problems that may arise include:

  • rescue equipment or personnel contaminating the site
  • inherent site dangers from debris or damaged equipment
  • weakened structures
  • difficulties in maintaining communication
  • explosive atmospheres

Health , safety and environment  (HSE )

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.

Relationship to Major Hazard Facility Legislation 

Organisations within the Chemical, Hydrocarbons and Oil Refining industries may find themselves falling under the provisions of various Major Hazard Facilities legislation. In developing this unit consideration has been given to the requirements of Sections 8 and 9 of the National Standard for the Control of Major Hazard Facilities [NOHSC:1014(2002)] and the National Code of Practice for the Control of Major Hazard Facilities [NOHSC:2016(1996)].

This unit will assist individuals to meet some of their obligations under the relevant State or Territory legislation. Responsibility for appropriate contextualisation and application of the unit to ensure compliance however, remains with the individual organisation.
