Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

DEFSU003B - Employ visual emergency signalling techniques in a survival situation

What evidence can you provide to prove your understanding of each of the following citeria?

Prepare for the construction of visual emergency signals

  1. Available natural and artificial resources are assessed for their application in emergency signalling
  2. Local area is examined to identify the ground that would afford optimum visibility to searchers but minimum physical effort to the survivor
  3. Sun's transit is observed and noted to determine the optimum placement of reflective signalling devices

Prepare emergency signaling devices for use

  1. Ground-to-air emergency signals are sited and constructed using purpose signal marker panels and/or improvised markers to optimise visibility from the air
  2. Tinsel/Christmas tree devices are sited and constructed using artificial resources, to optimise visibility from the air
  3. An emergency signal fire is sited and constructed to optimise visibility from the air

Instructions to Assessors

Evidence Guide

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

Assessment must confirm the ability to:

accurately 'illuminate' a target at least 300 m away

site and build a trench symbol visible from the air at 2 000 m (may be a simulated trench if ground is too hard i.e. through use of charcoal, rocks etc.)

site and construct a tinsel tree to be visible from the air at 2 000 m

site, construct and maintain the fuel and foliage stock for the fire and on order, light the fire so that it is well ablaze within 120 seconds and then generate smoke through the application of green foliage.

Consistency in performance

Competency should be demonstrated in a range of simulated visual emergency signalling techniques that could be expected in a survival situation.

Context of and specific resources for assessment

Context of assessment

Competency must be assessed in a simulated environment.

While a person can demonstrate the technical ability to employ visual signalling devices, doing so in a survival situation is crucial; consequently it is strongly recommended that holistic assessment be conducted with other associated survival units.

Assessment under simulated survival conditions should include:

food restrictions (food should be restricted to half the recommended daily caloric intake)

the absence of normal living conditions and amenities such as showers, beds and bedding (warmth to be provided by fire), kitchens etc. with the attendant levels of personal discomfort and fatigue

a significant period of time - the recommendation is four days.

Specific resources for assessment

Access to emergency signalling devices.

Required Skills and Knowledge

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