This is the second edition of CSA Z275.5, Occupational diver Training. It supersedes the previous edition, published in 2005. This Standard contains requirements and performance specifications for occupational diver training facilities and curricula. It also provides prerequisites for diver training candidates and for the consideration of prior learning for divers seeking upgrades or recognition of diving competency.

This Standard has been designed to parallel the competency criteria found in CSA Z275.4,Competency Standard for Diving, Hyperbaric Chamber, and Remotely-operated Vehicle Operations, for various diving categories and types of support personnel. This Standard specifies the facilities, equipment, objectives, and curriculum elements necessary to train a diver to the competency levels for each diving category specified in CSA Z275.4. In addition, CSA Z275.5 forms the basis for a national diver training facility auditing program.

This new edition of the Standard adds training requirements for offshore diving safety specialists (see Clause 26), as well as for a new category of support personnel; the inshore diving safety specialist (see Clause 27). It also adds training requirements for oxygen-enriched air divers and supervisors (see Clauses 29 to 31).

Users of this Standard should understand that the requirements specify minimum levels only. This Standard does not have the force of law unless mandated by legislation or called up in the regulations of the authority having jurisdiction. Users are advised to contact the authority having jurisdiction in their area in order to determine the extent to which this Standard is referenced.


This Standard applies to occupational diver trainees, training organizations, instructors, and facilities. It describes the requirements for trainee assessment, instructor qualifications, and minimum equipment for each level of training. This Standard also provides guidance on the auditing of diver training facilities and programs. Its purpose is to ensure that the competency levels specified in CSA Z275.4 can be achieved within programs offered by accredited training facilities and that divers who successfully complete those programs can be considered competent at the level trained, in accordance with CSA Z275.4.

This Standard addresses training for the following levels of competency:

a) restricted SCUBA diver (Clause 5);

b) unrestricted SCUBA diver (Clause 6);

c) SCUBA tender (Clause 7);

d) SCUBA supervisor (Clause 8);

e) restricted surface-supplied diver (Clause 9);

This Standard does not include training for special competency requirements for unexploded explosive ordnance (UXO) diving operations. Refer to CSA Z275.6 for training requirements related to these special competencies.

This Standard is designed to be applied to those individuals without prior educational or practical experience in a category of diving and its associated disciplines. Clause 3 provides requirements for assessing the prior learning and experience of individual divers and for determining the training required for these individuals to meet the competency requirements of CSA Z275.4.

In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.
