Elements and Performance Criteria
- Prepare for the construction of visual emergency signals
- Available natural and artificial resources are assessed for their application in emergency signalling
- Local area is examined to identify the ground that would afford optimum visibility to searchers but minimum physical effort to the survivor
- Sun's transit is observed and noted to determine the optimum placement of reflective signalling devices
- Prepare emergency signaling devices for use
- Ground-to-air emergency signals are sited and constructed using purpose signal marker panels and/or improvised markers to optimise visibility from the air
- Tinsel/Christmas tree devices are sited and constructed using artificial resources, to optimise visibility from the air
- An emergency signal fire is sited and constructed to optimise visibility from the air
- Shadow trenches are sited and excavated
- Purpose built signalling devices are prepared
- Employ visual emergency signals
