Application
This competency normally applies to the individual who is required to assemble and disassemble firing circuits, and to fix detonators, primers, firing devices and explosive charges in accordance with the demolition supervising officer's plan in an underwater environment. The individual is also required to handle, transport and protect explosives in an underwater environment. | |
Prerequisites
Pre-requisite Unit/s | PUADEFDV001C Dive using self-contained underwater breathing apparatus in open water to 30 metres PUADEFEO711C Conduct military demolition operations |
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
1. Prepare for underwater demolitions | 1.1 Work task and worksite data are determined and analysed to determine the specific requirements for the explosive demolition 1.2 Work plan is developed consistent with the dive plan 1.3 Explosives, associated equipment and protective equipment are selected, inspected and prepared 1.4 Explosives and associated equipmentare secured safely to/from the dive site 1.5 Access obstructions and other hazards are assessed and action is taken to remove/reduce the risk |
2. Conduct underwater demolition | 2.1 Explosives and associated equipment are secured on self 2.2 Work-safe area is established at the demolition site and the location of divers is confirmed prior to commencing demolition task/s 2.3 Hazards relevant to the application of explosives and associated equipment are identified and managed 2.4 Charges are fixed and placed, line is laid, timing devices are set, firing point is established and circuit is connected and tested 2.5 Location and safety of personnel is confirmed prior to firing the demolition 2.6 Demolition is fired |
3. Conduct post-demolition procedures | 3.1 Environmental impact arising from use of explosives is minimised and waste products are recovered 3.2 Demolition circuit is disassembled 3.3 Explosives and associated equipment are recovered, de-serviced and stored for re-use or disposed of 3.4 Usage of explosives and associated equipment is recorded |
Required Skills
This describes the essential skills and knowledge and their level, required for this unit. |
Required Skills |
ability to dive fire explosive ordnance handle and care for explosives set-up explosive circuits |
Required Knowledge |
dangers to explosives dive equipment dive physics effect of water on explosives explosive charges general occupational/diving safety awareness land based explosive demolitions oceanography relevant references and Australian Standards work hazards |
Evidence Required
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. | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessment must confirm the ability to: fix and place appropriate charges implement occupational health and safety policies and procedures implement diving safety awareness strategies. Consistency in performance Competency should be demonstrated during a demolition task over a time frame that allows for the safe demonstration of competency. |
Context of and specific resources for assessment | Context of assessment Competency should be assessed in the ocean for all practical assessments, supported by questioning on shore or aboard vessels. When practicable, assessment should relate to the diver's vocational focus. Specific resources for assessment Access is required to: complete range of diving, safety and accessory equipment explosives associated equipment. |
Method of assessment | This unit may be assessed with the following unit: PUADEFEO101D Work safely with explosive ordnance. In a public safety environment assessment is usually conducted via direct observation in a training environment or in the workplace via subject matter supervision and/or mentoring, which is typically recorded in a competency workbook. Assessment is completed using appropriately qualified assessors who select the most appropriate method of assessment. Assessment may occur in an operational environment or in an industry-approved simulated work environment. Forms of assessment that are typically used include: direct observation interviewing the candidate journals and workplace documentation third party reports from supervisors written or oral questions. |
