Modification History


TP Version 




Initial release. Supersedes and is not equivalent to SFIDIVE305B Undertake emergency procedures in diving operations using self-contained underwater breathing apparatus

Unit Descriptor

This unit of competency involves acting as a surface and in-water standby diver, providing assistance in an emergency situation and performing a self-rescue ascent during occupational diving operations using self-contained underwater breathing apparatus (SCUBA).

Licensing, legislative, regulatory or certification requirements may apply to this unit. Therefore it will be necessary to check with the relevant state or territory regulators for current licensing, legislative or regulatory requirements before undertaking this unit.

Application of the Unit

Completion of this and other diving units may lead to further accreditation in occupational diving by industry and/or regulatory authorities. Check with the relevant industry or regulatory body for specific requirements.

All enterprise or workplace procedures and activities are carried out according to relevant government regulations , licensing and other compliance requirements , including occupational health and safety  (OHS ) guidelines , and maritime and occupational diver codes of practice and procedures.

Equipment operation, maintenance, repairs and calibrations are undertaken in a safe manner that conforms to manufacturer instructions. Appropriate personal protective equipment  (PPE ) is selected, checked, used and maintained.

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria



1. Perform surface standby-diver activities for divers using SCUBA

1.1. Surface standby-diver activities during operations  conform to appropriate emergency/rescue procedures according to the equipment  used

1.2. A state of readiness to ensure prompt action in the event of an emergency  is maintained at all times

2. Perform in-water standby-diver activities using SCUBA

2.1. In-water standby-diver activities conform to appropriate emergency/rescue procedures according to the equipment used

2.2. Communication  lines are maintained with the surface team to ensure all necessary rescue action is undertaken

3. Employ correct techniques for emergency situations when using SCUBA

3.1. Assistance  is given in the recovery of an unconscious or injured diver from the surface to dry land or the deck of a dive platform in a manner that prevents further injury

3.2. Ascent  in an emergency situation is managed by controlling buoyancy, while identifying an emergency situation where shedding weights  may be necessary
