  1. have been assessed as competent for in-water rescue such as recreational dive Supervisor, rescue diver, SISCAQU306A Supervise clients at an aquatic facility or environment, PUA21012 Certificate II in Public Safety (Aquatic Rescue) or PUASAR013A Participate in aquatic rescue operations;
  2. hold a current certificate for first aid;
  3. hold a current certificate for CPR; and
  4. hold a current certificate for advanced resuscitation or the provision of 100% oxygen. 

Requirements for Snorkel Supervisor

(13) A snorkel supervisor must satisfy the competencies in clauses 8-12 and be appointed in writing as a snorkel supervisor by the Supervisor responsible for the snorkelling activity/work.

Minimum size of Snorkelling Teams

Snorkelling Operations in Open Water

(14) The following personnel must be present:

  1. one (1) snorkel supervisor;
  2. two (2) snorkellers, each acting as in-water rescuer for the other snorkeller; and
  3. one (1) lookout.

(15) The snorkel supervisor may act as either a snorkeller or lookout. The minimum team is therefore three (3) persons. If the snorkel supervisor is acting as a snorkeller, a lookout must be appointed.

(16) One lookout may attend to more than one pair of snorkellers if:

  1. this is supported by a documented risk assessment;
  2. the snorkellers are working in the same immediate vicinity; and 
  3. this does not compromise the snorkel team's ability to respond to an emergency.

Snorkelling Operations in Water Depths up to 1.5m

(17) The following personnel must be present:

  1. one (1) snorkel supervisor;
  2. one (1) snorkeller; and
  3. one (1) lookout.

(18) The snorkel supervisor may act as either a snorkeller or lookout if:

  1. this is supported by a documented risk assessment;
  2. this does not compromise the snorkel team's ability to respond to an emergency; and
  3. the snorkelling operation does not involve:
    1. poor visibility;
    2. danger to the snorkeller from currents either natural or associated with man-made structures such as dams, weirs, inlets, outlets or sluices;
    3. risk of entrapment of the snorkeller or entanglement and provides unimpeded access to the surface; or
    4. a situation in which third party assistance is not readily available in an emergency.

(19) If a snorkel team of two (2) is used, the attendant must maintain visual contact with the snorkeller and must be capable of removing the snorkeller from the water in an emergency or if the snorkeller requests assistance. The minimum team is therefore two (2) persons. 

Snorkelling Operations in Sheltered Open Water

(20) The following personnel must be present:

  1. one (1) snorkel supervisor;
  2. two (2) snorkellers, each acting as in-water standby snorkeller for the other snorkeller; and
  3. one (1) snorkeller's attendant.

(21) The snorkel supervisor may act as either a snorkeller or snorkeller’s attendant. The minimum team is therefore three persons. If the snorkel supervisor is acting as a snorkeller, the supervisor's surface duties must be delegated to the attendant.

(22) In exceptional circumstances, where minimal risk is present, the Supervisor and Head of School or Head of Organisational Unit may authorise a minimum team of two snorkellers if:

  1. this is supported by a documented risk assessment;
  2. this does not compromise the snorkel team's ability to respond to an emergency; and
  3. the snorkelling operation does not involve:
    1. poor visibility;
    2. danger to the snorkeller from currents either natural or associated with man-made structures such as dams, weirs, inlets, outlets or sluices;
    3. risk of entrapment of the snorkeller or entanglement and provides unimpeded access to the surface; or
    4. a situation in which third party assistance is not readily available in an emergency.

(23) If a snorkel team of two (2) is used, each snorkeller must maintain visual contact with the snorkeller and must be capable of removing the snorkeller from the water in an emergency or if the snorkeller requests assistance. The minimum team is therefore two (2) persons. 

Supervision of Large Groups

(24) For groups of snorkellers without rescuer skills, competent persons must be appointed by the Supervisor at ratios no lower than:

  1. one (1) snorkel supervisor per 32 persons;
  2. one (1) snorkel rescuer per 16 persons; and
  3. one (1) snorkel guide per eight (8) persons.

(25) Snorkel rescuers may act as snorkel guides. Snorkel supervisors may act a guide and as a snorkel rescuer.

(26) The above ratios are for nominal low risk conditions. Minimum ratios of competent persons to snorkellers must be reduced according to a risk assessment where snorkellers are mostly inexperienced, at night, or according to the environmental conditions.

(27) For all night snorkelling activities, where a risk assessment permits no lookout to be used, or where the sea state exceeds 1m, minimum ratios of competent persons to snorkellers must be reduced to:

  1. one (1) snorkel supervisor per 16 persons;
  2. one (1) snorkel rescuer per eight (8) persons; and
  3. one (1) snorkel guide per four (4) persons.

(28) Snorkel lookouts for large groups should wear distinctive brightly coloured clothing and be equipped with binoculars, polarised sunglasses and communications equipment so that effective communications can be made with the snorkelling supervisor and people in the water.

(29) The Supervisor and snorkel supervisor must assess the snorkel registration form of all participants to identify any persons at higher risk when snorkelling. The Supervisor and snorkel supervisor must ensure that persons at higher risk when snorkelling have adequate supervision (e.g. by reducing the number of other snorkellers in a guide's group, or by visually identifying the higher risk snorkellers using different coloured snorkels or other PPE).

Work Off-campus (WOC) Plan for Snorkelling

(30) A WOC plan as per the Work Off-Campus and Fieldwork Procedure for snorkelling must include:

  1. the method of carrying out the work whilst snorkelling;
  2. tasks and duties of each person;
  3. procedures to be used;
  4. anticipated time in water; and
  5. hazards with residual risk above low and the control measures to be implemented.

(31) Where the work is complex or where groups of over 8 persons are snorkelling, the plan should be completed on a separate snorkel plan to be attached to the WOC plan.

(32) As per the Work Off-Campus and Fieldwork Procedure, WOC plans should be completed in UQSafe-Field Trip.

Risk Management

(33) A risk assessment must be prepared by a person competent as a snorkel supervisor under this Procedure for all snorkelling work in accordance with the UQ Health and Safety Risk Assessment Procedure.

(34) In circumstances where the UQ Risk Management Database is not accessible to the entire snorkelling team, alternative methodologies that comply with the How to Manage Work Health and Safety Risks Code of Practice 2021 (Qld) may be utilised. These methodologies may be used to implement more effective controls in the event of variation in the previously identified hazards in Supervisor approved assessment.

(35) The hazard identification checklist in the approved snorkel plan should be used to assist in identifying the potential hazards.

(36) The snorkel supervisor must ensure that:

  1. all workers are consulted regarding the risk assessment prior to work commencing; and
  2. all of the controls nominated in the risk assessment have been implemented.

Conditions Under Which Snorkelling and Breath-hold Diving Should Not be Undertaken

(37) Due to the consequences of becoming entangled in unseen objects, snorkelling must not be conducted where there is:

  1. a high residual risk of entanglement; or 
  2. very low visibility (<1m) unless the depth of water is less than 1m.

(38) Breath-hold diving must not be conducted where there is:

  1. moderate or higher residual risk of entanglement; or
  2. low visibility (<3m);
  3. the work requires moderate or prolonged exertion whilst breath-holding; or
  4. working depth exceeds 15m.

Snorkelling From Large (Over 12m Measured Length) Vessels 

(39) A suitable small auxiliary vessel must be immediately available to assist with emergency procedures where snorkelling is conducted from a vessel larger than 12m measured length.

Management of Risk from Non-associated Vessel Traffic

(40) On navigable waters a dive flag in compliance with local regulation should be flown in a way to maximise visibility. In most waters, this is the international code of signals Code A flag.

(41) Where snorkelling is conducted from a vessel at night, the vessel must display restricted in ability to manoeuvre lights in accordance with Rule 27 of the International Regulations for Preventing Collisions at Sea 1972.

Shallow Water (Hypoxic) Blackout

(42) Due to the unavoidable risk of shallow water blackout, no work utilising breath hold diving should be conducted deeper than 15m.

(43) At all times, snorkellers undertaking breath-hold diving must work in pairs, with one snorkeller remaining at the surface while the second undertakes a breath-hold dive. The snorkeller remaining at the surface must be in a state of immediate readiness to rescue the breath-hold diver and should maintain visual contact with the breath-hold diver at all times the breath-hold diver is underwater.

Breath-hold Diving Following Compressed Gas Diving 

(44) Breath-hold diving must not be undertaken following compressed gas diving until the diver has off-gassed the residual inert gas. Using DCIEM tables, the diver should have a repetitive factor of 1.0 before undertaking any breath-hold dive.

Snorkelling at Night

(45) All snorkellers undertaking snorkelling at night must carry a minimum of two light sources. One of these light sources should be a chemical light stick attached to a highly visible part of the snorkeller such as the snorkel.

Emergency Plans

(46) Emergency plans must be in writing and provide procedures for:

  1. the recall of all snorkellers;
  2. recovery of a snorkeller to the vessel or shore or other place where first aid can be effectively provided;
  3. the minimum number of persons with first aid training and the minimum level of first aid training of those persons (see clauses 8-13 and clauses 14-23);
  4. the minimum volume of medical grade oxygen to be onsite;
  5. transfer of an injured snorkeller to:
    1. the emergency services; or
    2. a facility that administers medical aid; and
  6. lost or overdue snorkeller/s.
