Diving and snorkelling

All dive equipment used on University dive trips must be serviced annually or to manufacturer's specifications and be in good working order. The University stocks some dive equipment for loan but if personal equipment such as BCD’s and Regulators are preferred, please forward scanned copies of the annual service record to the Maritime Safety Dive Officer prior to undertaking the dive trip. Note, any faulty equipment must be tagged out immediately, recorded on the Diving Safety Log and reported to the Maritime Safety Dive Officer.

New University divers are required to undertake a check out dive with the Maritime Safety Dive Officer or an experienced dive coordinator, refer to the new diver/snorkeller evaluation form.

To ensure safe diving operations, a defined diving structure exists within the University, based on training, experience and role in the dive team. The categories are as follows: 

• Restricted scientific diver: Open Water Diver with 18 hours dives minimum experience. Must be supervised in-water by a General Scientific Diver or Dive Coordinator. Depth limit 12m.
• Limited scientific diver: Rescue Diver, 60 hours and 5 scientific dives with the University (or equivalent). Able to undertake scientific diving to a depth of 18m.
• General scientific diver: Professional Dive Leader qualification (i.e. Dive Master) or Occupational dive qualification (i.e. AS/NZS 2815), 80 hours and 10 scientific dives with the University (or equivalent). Able to be an in-water Dive Leader. Depth limit 24m.
• Dive coordinator: Professional Dive Leader qualification or Occupational dive qualification, 100 hours and 20 scientific dives with the University (or equivalent). Depth limit 30m. Dive coordinator has the authority to coordinate University Diving operations, selection is based on individuals who poses leadership skills, sound judgement with a demonstrated ability to follow Flinders dive protocol and run safe diving operations.

Refer to section 2.3 of the Diving and Snorkelling procedures manual for full details.

On a dive site there is a distinct chain of command and direction given by these responsible persons must be followed by all members of the dive team. 

• The Field Trip Leader is responsible for the conduct of the overall trip.
• The Dive Coordinator is responsible for the overall running and safe conduct of a diving operation.
• The in-water Dive Leader is responsible for the safe conduct of their diving team including keeping a close watch on less experience divers in-water.
  
• Where applicable, the Skipper/ Coxswain is in charge of the vessel and safety of the personnel on-board.
• Note, the Maritime Safety Dive Officer is in charge of managing all diving and boating conducted through the University and has the authority to restrict, prohibit or suspend activities, or require additional safety practices, procedures or equipment to ensure safety. Note, any changes to a Dive Plan must first be cleared by the Maritime Safety Dive Officer.

Under the supervision of the dive coordinator, University Diving operations must follow protocol as set out in the Diving and snorkelling procedures manual.

The dive coordinator must complete the following:

a) Diving on-site risk assessment

b) Diving safety briefing

c) Diving equipment checklist

d) Diving safety log

cd) Diving equipment checklist and safety log combined

Note, scanned copies of all dive forms must be submitted to the Maritime Safety Dive Officer post trip.

Please adhere to the Diving and snorkelling safety procedures and read the Diving and snorkelling procedures manual for a full understanding of the dive protocol the University has in place.

In short:

As a general guide, snorkelling by Flinders University personnel should only be used as an observation, photography, search or collection technique. No difficult or strenuous work of any kind should be attempted using snorkel diving, without implementation of appropriate safety precautions and approved by the Maritime Safety Dive Officer.

All Flinders University snorkellers should have as a minimum:

• Recreational Dive Medical (valid within the last 3 years).
  • Snorkelling AS4005.1 Recreational Dive Medical form
  • Dive medical doctors
• At least 5 hours snorkelling experience.
• Should be competent swimmers i.e. able to swim 400m in under 12mins and tread water for 10mins (without fins).

All Flinders University snorkel leaders should have the above but also have:

• Rescue diver minimum and appropriate snorkelling experience.
  • Current Provide First Aid (HLTAID003) (renewed every 3 years).
  • Oxygen Provider and CPR training (renewed annually).
