1.1 General

1.1.1

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 might 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.

1.1.2

This Standard addresses the minimum equipment requirements and operational procedures for the following diving systems and work environments:

a)     SCUBA diving systems (see Clause 7);

b)     surface-supplied diving systems (see Clause 8);

c)     deep diving systems (see Clause 9);

d)     one-atmosphere diving systems (see Clause 10); and

e)     diving in contaminated environments (see Clause 11).

f)      nitrox diving (see Clause 12)

g)     unexploded explosive ordnance (UXO), munitions, and police explosive diving (see Clause 13)

Note: The information relating to unexploded explosive ordnance (UXO), munitions, and police explosive diving was previously contained in standard Z275.6. Competencies for this work are still contained in Z275.6 until incorporated into Z275.4.

1.2 Limitations

1.2.1

This Standard does not apply to scientific diving as defined in Clause 3. However, for clarification, diving that is conducted outside of the Definition in Clause 3 does fall under this Standard.

1.2.2

This Standard does not apply to diving operations performed solely for sport or recreation.

1.2.3

This Standard does not include work techniques associated with underwater diving operations.

1.3 Terminology

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 (non-mandatory) 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. Where values are given in parentheses, they are for information and comparison only.

1.1 Scope of the B1800 compendium

This Compendium specifies requirements for compounds and for manufactured pipe and pipe fittings, the relevant test methods, and marking requirements, and applies to thermoplastic nonpressure piping including

a) drain, waste, and vent pipe and pipe fittings;

b) sewer and storm pipe and pipe fittings; and

c) accessories such as factory-assembled expansion joints, closet flanges, backwater valves, and cleanouts.

Notes:

This Compendium does not specify requirements for venting of combustion gases. In Canada, ULC S636 specifies testing and marking requirements for pipe, fittings, and accessories intended for venting of combustion gases. In the U.S., UL 1738 specifies testing and marking requirements for pipe, fittings, and accessories intended for venting of combustion gases.

This Standard Compendium does not specify requirements for piping for venting of soil gases, including venting of radon gas. CAN/CGSB 149.11 provides guidance on acceptable pipe and fitting standards and marking requirements.

1.2 Scope of this Standard

This Standard specifies definitions, general requirements for compounds and for manufactured pipe and pipe fittings, the relevant test methods, and marking requirements.

1.3 Intent of this Standard

This Standard is intended to be used in conjunction with one of the other Standards in the CSA B181 or CSA B182 series to form a complete Standard for a particular product.

1.4 Terminology

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 (non-mandatory) to define their application. 

1.1 General

This Standard specifies requirements for acrylonitrile-butadiene-styrene (ABS) drain, waste, and vent (DWV) pipe, pipe fittings (including push-fit fittings), and accessories such as factory-assembled expansion joints, closet flanges, and backwater valves.

Notes:

Recommended installation practices for ABS-DWV pipe are specified in Annex A. Use of these recommended practices can help to ensure proper installation and optimum service life.

The maximum pressure used to test DWV installations should be 100 kPa (see Clause A.5.2).

This Standard does not specify requirements for venting of combustion gases. In Canada, ULC S636 specifies testing and marking requirements for pipe, fittings, and accessories intended for venting of combustion gases. In the U.S., UL 1738 specifies testing and marking requirements for pipe, fittings, and accessories intended for venting of combustion gases.

This Standard does not specify requirements for piping for venting of soil gases, including venting of radon gas. CAN/CGSB 149.11 provides guidance on acceptable pipe and fitting standards and marking requirements.

1.1 General

This Standard specifies requirements for polyvinylchloride (PVC) and chlorinated polyvinylchloride (CPVC) drain, waste, and vent (DWV) pipe, pipe fittings (including push-fit fittings), and accessories such as factory-assembled expansion joints, closet flanges, backwater valves, and pipe fittings intended for use in fire-stops fittings*.

*The fire stop is for use in fire separations only. It can be Firestops are subject to code requirements not covered in this Standard.

Notes:

Recommended installation practices for PVC-DWV pipe are specified in Annex A. Following these practices will help ensure proper installation and optimum service life.

The maximum pressure used to test DWV installations should be 100 kPa (see Clause A.5.2).

This Standard does not specify requirements for venting of combustion gases.
