Respond to emergency as standby diver[edit | edit source]

Deploy as standby diver
Remain ready for immeadiate deployment while the working diver is in the water
On instruction from the supervisor, lock into hat, report to supervisor ready to enter water
On instruction from supervisor, enter water and complete in-water checks. Report status to supervisor.
On instruction from supervisor, follow diver's umbilical and descend to distressed diver
Provide running commentary of progress during dive.
Trapped or fouled diver or umbilical
(diver still communicating)
Free diver's umbilical from snags if applicable, reasonably practicable, and diver is known to be responsive.
As far as reasonably practicable, ensure own umbilical does not snag.

Unresponsive diver
(diver not communicating)
On sighting diver, report what can be seen regarding hazards and condition of diver.
On reaching diver, assess responsiveness of diver, evidence of breathing and general condition of diver as may be visible

Follow emergency plans[edit | edit source]

Respond to emergencies by following the emergency plans described in the operations plan or operations manual List the classes of emergency for which an emergency plan should be in place before a diving operation Reasonably foreseeable emergencies that are not covered by standard emergency procedures should be allowed for in diving operation planning. These are generally plans which would vary depending on the circumstances of the operation. Examples include:

  • Lost diver: At some sites this is not possible, at others the procedures required for search and recovery may vary considerably depending on the geography of the site and the mode of diving.
  • Man overboard: Procedures will largely depend on the vessel or platform, and the personnel responsible for responding, which may not be the dive team.
  • Deteriorating environmental conditions: Some sites may be subject to unusual environmental hazards. Risk may be to the diver, or the whole team.
  • Job-specific emergencies: Some operations involve hazardous materials or equipment.
