Z275.5-05 (R2012)

For over 40 years, CSA Group standards have helped mitigate specific risks and hazards associated with occupational diving and hyperbaric environments. The CSA Z275 series of standards set out requirements for most kinds of occupational diving as well as provide guidance for supervisors and support personnel. Diver training is a critical element to overall diver safety. CSA Z275.5 contains requirements and performance specifications for professional diver training facilities and curricula as well as prerequisites for diver training candidates.

Highlights of Z275.5 Include:

• Contains performance specifications for both divers seeking upgrades or those seeking diver competency recognition
• Applies to occupational diver trainees, training organizations, instructors, and facilities
• Describes the requirements for trainee assessment, instructor qualifications, and minimum equipment for each level of training
• Provides guidance on the auditing of diver training facilities and programs

This is the first edition of CSA Z275.5, Occupational diver training.
This Standard contains requirements and performance specifications for professional 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.

Scope

1.1
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 CAN/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 CAN/CSA-Z275.4.

1.2
This Standard addresses training for the following levels of competency:
(a) restricted SCUBA diver (Clause 4);
(b) unrestricted SCUBA diver (Clause 5);
(c) SCUBA tender (Clause 6);
(d) SCUBA supervisor (Clause 7);
(e) restricted surface-supplied diver (Clause 8);
(f) unrestricted surface-supplied diver (Clause 9);
(g) surface-supplied mixed-gas diver (Clause 10);
(h) surface-supplied tender (Clause 11);
(i) surface-supplied mixed-gas tender (Clause 12);
(j) restricted surface-supplied supervisor (Clause 13);
(k) unrestricted surface-supplied supervisor (Clause 14);
(l) surface-supplied mixed-gas supervisor (Clause 15);
(m) bell diver (Clause 16);
(n) bell diving tender (Clause 17);
(o) bell diving supervisor (Clause 18);
(p) atmospheric diving system (ADS) pilot (Clause 19);
(q) ADS technician (Clause 20);
(r) ADS supervisor (Clause 21);
(s) hyperbaric chamber operator (Clause 22);
(t) hyperbaric life-support technician (Clause 23);
(u) diving medical technician (Clause 24);
(v) offshore diving safety specialist (Clause 25);
(w) diving and hyperbaric physician (Clause 26);
(x) oxygen-enriched-air SCUBA diver (Clause 27);
(y) oxygen-enriched-air surface-supplied diver (Clause 28); and
(z) oxygen-enriched-air supervisor (Clause 29).

1.3
This Standard is designed to be applied to those students 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 CAN/CSA-Z275.4.
1.4
In CSA Standards, 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; may is used to express an option or that which is permissible within the limits of the standard; and can is used to express possibility or capability.

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 (non-mandatory) to define their application.
