This process brings together volunteers representing varied viewpoints and interests to achieve consensus and develop a standard. Although CSA Group administers the process and establishes rules to promote fairness in achieving consensus, it does not independently test, evaluate, or verify the content of standards.

Canadian Standards Association (operating as “CSA Group”), under whose auspices this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for- profit, nonstatutory, voluntary membership association engaged in standards development and certification activities.

CSA Group standards reflect a national consensus of producers and users — including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment.

Individuals, companies, and associations across Canada indicate their support for CSA Group’s standards development by

volunteering their time and skills to Committee work and supporting CSA Group’s objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSA Group’s total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSA Group’s standards development activities.

CSA Group offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, CSA Group regularly and continually audits and inspects products that bear the

CSA Group Mark.

In addition to its head office and laboratory complex in Toronto, CSA Group has regional branch offices in major centres across Canada and inspection and testing agencies in eight countries. Since 1919, CSA Group has developed the necessary expertise to meet its corporate mission: CSA Group is an independent service

organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification and related services to meet national and international needs.

Preface

This is the sixth edition of CSA Z180.1, Compressed breathing air and systems. It supersedes the previous editions published in 2013, 2000, 1985, 1978, and 1973.

Where appropriate, this Standard has been harmonized with other national and international standards dealing with compressed breathing air and systems, e.g., CSA Z275.2.

New to this edition is a compliance checklist (Annex F). This checklist is provided in order to assist users in compliance auditing. It highlights the critical requirements of the Standard that should be regularly checked as part of a respiratory protection program (as detailed in CAN/CSA-Z94.4).

This Standard was prepared by the Technical Committee on Compressed Breathing Air and Systems, under the jurisdiction of the Strategic Steering Committee on Occupational Health and Safety, and has been formally approved by the Technical Committee.

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Notes:

1. Use of the singular does not exclude the plural (and vice versa) when the sense allows.

2. Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.

3. This Standard was developed by consensus, which is defined by CSA Policy governing standardization — Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this Standard.

4. To submit a request for interpretation of this Standard, please send the following information to

   inquiries@csagroup.org and include “Request for interpretation” in the subject line:

   1. define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;

   2. provide an explanation of circumstances surrounding the actual field condition; and

   3. where possible, phrase the request in such a way that a specific “yes” or “no” answer will address the issue.

      Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are available on the Current Standard Activities page at standardsactivities.csa.ca.

5. This Standard is subject to review within five years from the date of publication. Suggestions for its improvement will be referred to the appropriate committee. To submit a proposal for change, please send the following information to inquiries@csagroup.org and include “Proposal for change” in the subject line:

   1. Standard designation (number);

   2. relevant clause, table, and/or figure number;

   3. wording of the proposed change; and

   4. rationale for the change.

CSA Z180.1:19

Compressed breathing air and systems

1 Scope

1.1

This Standard provides the minimum requirements, unless otherwise specified by the authority having jurisdiction, for the purity of compressed breathing air supplied to the service outlet and for breathing air systems required to produce, store, and distribute such air.

1.2

This Standard is limited to compressed breathing air and compressed breathing air systems used in the following applications:

1. supplied-air respirators;

2. supplied-air suits;

3. self-contained breathing apparatus (SCBA) (open circuit);

4. ambient air systems; and

5. other applications for which qualified persons deem it appropriate to reference the compressed breathing air purity requirements described in this Standard, e.g., vortex tubes used for heating and cooling supplied-air suits.

   Notes:

   1. Implementation of the requirements of this Standard within a respiratory protection program is addressed in CAN/CSA-Z94.4.

   2. The manufacturer, the applicable testing agency, and the authority having jurisdiction should be consulted for quality requirements for breathing gas in closed-circuit SCBA.

   3. For diving operations, refer to CSA Z275.2.

1.3

This Standard includes requirements applicable to the design, construction, commissioning, calibration, testing, operation, and maintenance of components for compressed breathing air systems.

1.4

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 (non-mandatory) to define their application.
