This is the fifth edition of CSA Z275.2, Occupational safety code for diving operations. It supersedes the previous editions published in 2004, 1992, 1982, and 1974. It is part of a series of Standards on diving and caisson systems covering hyperbaric facilities, occupational diving, and construction work in compressed air.
This Standard applies to occupational diving operations conducted in connection with all types of work and employment, and describes the requirements for occupational safety.
Note: It is recognized that certain underwater tasks may require specialized standards of practice and/or operational techniques that differ from the requirements of this Standard yet may be acceptable to the authority having jurisdiction.
Users should consult applicable provincial and federal occupational safety and health regulations to determine whether they impose safety requirements additional to or more stringent than those of this Standard.
This Standard addresses equipment requirements for the following diving systems:
(a) SCUBA diving systems (see Clause 7);
(b) surface-supply diving systems (see Clause 8);
(c) deep-diving systems (see Clause 9); and
(d) diving in contaminated environments (see Clause 10).
This Standard does not apply to scientific diving as defined in Clause 3.
This Standard does not apply to diving operations performed solely for sport or recreation.
This Standard does not include work techniques associated with underwater diving operations.
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; 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.
1.4 Units of measurement
The values given in SI units are the units of record for the purposes of this standard. The values given in parentheses are for information and comparison only.
