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. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
Relevant government regulations, licensing and other compliance requirements may include: | business or workplace operations, policies and practices correct marketing names and labelling safety at sea OHS hazard identification, risk assessment and control. |
OHS guidelines may include: | appropriate clothing and safety equipment for use with waders appropriate workplace provision of first aid codes of practice, regulations and/or guidance notes which may apply in a jurisdiction or industry sector enterprise-specific OHS procedures, policies or standards hazard and risk assessment of workplace, maintenance activities and control measures induction or training of staff, contractors and visitors in relevant OHS procedures and/or requirements to allow them to carry out their duties in a safe manner OHS training register safe lifting, carrying and handling techniques safe systems and procedures for outdoor work, including protection from solar radiation, use of waders and the protection of people in the workplace systems and procedures for the safe maintenance of property, machinery and equipment, including hydraulics and exposed moving parts. |
Types of waders include: | neoprene waders PVC waders waders with and without bibs. |
Environmental hazards may include: | bottom composition changing bottom characteristics over time cold air temperature, including wind chill factor cold water floating debris and equipment sudden changes in water depth or bottom composition underwater obstructions and snags water clarity water depth water movement (e.g. currents, tides and flow) wave action. |
Factors contributing to aquatic emergencies may include: | condition of casualty consumption of alcohol or use of prescription or other drugs that might affect performance environmental conditions equipment failure risk taking behaviour slippery surfaces swimming ability vessel instability or capsize. |
Sudden immersion in cold water may result in: | changes in blood circulation and pressure gasp reflex and hyperventilation, including reduced breath-holding capacity heart attack hypothermia impaired physical performance Mammalian Diving Reflex stroke. |
Types of aquatic emergencies may include: | bleeding wound cramping flooding of waders injury insect or aquatic organism bite or sting loss of footing medical emergency (e.g. heart attack, stroke and asthma) weak or non-swimmer in difficulty temperature related illness unexpected immersion. |
Factors that influence cold water survival time include: | body composition and size buoyancy aids clothing duration of immersion heat escape lessening techniques level and type of physical activity sea or water conditions water temperature wind chill. |
Appropriate clothing and safety equipment may include: | hat helmet jacket non-slip footwear personal flotation device (PFD) thermal or woollen wear wide belt to assist trapping of air. |
Entry techniques may include: | wade into water of shallow depth slide into water of unknown depth and obstructions step into water of known depth without obstructions dive into clear water of known depth without obstructions. |
Wading techniques include: | adjustment of equipment to prevent water ingress feeling with feet when wading in turbid water leaning against water when wading maintaining a safe working depth. |
Wader safety tuck position includes: | appropriate orientation for safe movement through water positioning on back sculling for efficient propulsion tucking legs to trap air in waders. |
Survival techniques include: | heat escape lessening techniques, including Heat Escape Lessening Posture (HELP) and huddle in-water removal of clothing and waders to achieve exit sculling and tread water techniques use of a belt to assist trapping of air in waders use of buoyant objects, including PFD. |
Techniques to extend survival time include: | energy conservation HELP and huddle techniques retention of clothing in cold water use of buoyant aids use of thermal protective clothing. |
Survival strokes may include | head and feet first sculling kicking on back underwater recovery arm action on front or back. |
A person in need of assistance may include: | injured swimmer non-swimmer unconscious person weak or tired swimmer. |
A rescue plan may include: | availability of assistance availability of rescue aids awareness of personal capabilities condition of person in difficulty environmental factors rescue priorities in the situation of more than one person in need of assistance self-preservation. |
Best practice principles of water safety may include: | guidelines and techniques published by water safety organisations, such as the Royal Life Saving Society Australia and Surf Life Saving Association Australia relevant legislation workplace procedures and guidelines. |
Search techniques include: | wading individually or in formation with others marking search area use of systematic search pattern appropriate to water depth and turbidity feeling with a stick or feet in turbid water. |
Simple rescue techniques may include: | dry rescues: reach rescue using pole, boat hook, paddle or other object rope throw rescue using weighted and unweighted rope throwing of a buoyant object, such as PFDs, lifebuoy or improvised aid use of watercraft in-water rescues: accompanied swim rescue wade rescue talking the casualty to safety. |
First aid and after-care may include: | hospitalisation in the case of near-drowning protection against environmental conditions with particular attention to hypothermia treatment according to current first aid guidelines. |
