Initial release. Supersedes and is not equivalent to SFIFISH201C Provide support for diving operations

Unit Descriptor

This unit of competency involves providing assistance to personnel conducting diving operations for work purposes. Support responsibilities may include performing checks on equipment, identifying occupational hazards and performing lookout duties. It may also include carrying out the roles and responsibilities of supervision when specified by industry guidelines.

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

This unit is applicable to a diving assistant in the fishing, aquaculture or ornamental/display sectors of the seafood industry.

Diving using breathing equipment is not required in this unit.

Codes of practice covering diving operations  for an industry sector and/or a geographic region may not require the support of a diving assistant. Reference should be made to local codes of practice and industry standards covering diving operations.

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 , maritime and occupational diver codes of practice and procedures and ecologically sustainable development  (ESD ) principles .

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.
