CSA Z94.3-2020

Eye and face protectors

Preface This is the ninth edition of CSA Z94.3, Eye and face protectors. It supersedes the previous editions, published in 2015, 2007, 2002, 1999, 1992, 1988, 1982, and 1969. Major changes to this edition include the following: • ignition resistance requirements for plano eyewear have been clarified and refined (Clause 6.2); • the flammability requirements and testing were deleted (Clause 6.2); • revised automatic darkening welding filter requirements (Clause 6.5.4); • added guidance for aftermarket components or accessories(Clause 6.7); • revised the minimum frontal coverage for plano eyewear (Clause 6.8); • revised side protection requirements for plano eyewear (Clause 6.9); • added cover lenses and cover plates for Class 2 protectors (Clause 8.7); • revised speed of steel balls for impact resistance testing (Clause 12.2.1.3); • revised the procedure for angular dependence of luminous transmittance test for automatic welding filter lenses (Clause 12.15.3); • revised marking and user information for plano eyewear (Clause 13.1); • revised markings for prescription protective eyewear (Clause 15.6); • added design and testing requirements for photochromic and polarized lenses for eyewear providing sun protection (Clauses 16.2.5, 16.2.6, and 16.3.5); • increased the number of prescription lens configurations presumed compliant (Table 5); • added a figure with measurement locations to Figure 9; and • updated the references (Clause 2) and definitions (Clause 3). As introduced in the 2002 edition, the basic performance requirements apply to all protectors covered in this Standard, whereas the test procedures specified differ for prescription eyewear and nonprescription eyewear. As in previous editions, for non-prescription protectors, specified testing procedures are to be conducted using the whole assembled product (not individual components). In contrast, for Class 1 protectors having prescription lenses, performance criteria and test procedures are applied to lenses and frames separately. This Standard sets out requirements for the manufacture of these protectors (e.g., quality assurance). In addition, special allowance has been made in this edition for the role of ophthalmic professionals in adjusting and modifying spectacles to fit the individual wearer. When taken together, these requirements provide a basis for conformity assessment of protective spectacles with prescription lenses. CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of the Canadian Association of Administrators of Labour Law – Occupational Safety and Health (CAALL-OSH), including Provincial and Territorial Governments, as well as the Government of Canada. CSA Group is solely responsible for the content of this Standard, and CSA Group and the funding bodies disclaim any liability in connection with the use of the information contained herein. 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. Scope 1.1 This Standard applies to eye and face protectors used in all occupational and educational operations or processes involving hazards to the eyes or face. Typical hazards include flying objects and particles, splashing liquids, molten metal, and ultraviolet, visible, and infrared radiation, but do not include X-rays, gamma rays, high-energy particulate radiation, radioactive materials, or masers. Note: The guidelines for protection outlined in Table A.1 should be followed when similar potentially hazardous activities are conducted in the home, at leisure, and in recreational environments. For certain sports activities, other Standards should be consulted (e.g., CSA Z262.2). 1.2 This Standard sets minimum performance requirements in the tests described herein but does not cover factors of design such as comfort, service life, or appearance. Note: The conformance of protectors with these requirements does not imply equality of performance, nor should it be interpreted to mean that protectors are capable of affording greater protection than is specified in this Standard. 1.3 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.

CSA B51-2019

B51-14 - Boiler, pressure vessel, and pressure piping code

Preface This is the nineteenth edition of CSA B51, Boiler, pressure vessel, and pressure piping code. It supersedes the previous editions published in 2014, 2009, 2003, 1997, 1995, 1991, 1986, 1981, 1975, 1972, 1969, 1965, 1960, 1957, 1955, 1951, 1945, and 1939. In keeping with CSA Group’s goal of harmonizing its standards with those of other countries to the greatest extent possible, CSA’s Technical Committee on Boilers and Pressure Vessels and its Subcommittees have, in the course of developing this Standard, worked closely with the National Board of Boiler and Pressure Vessel Inspectors in the United States and with the American Society of Mechanical Engineers (ASME) committees responsible for producing the National Board Inspection Code and ASME’s Boiler and Pressure Vessel Code. There are three parts to this Standard: a) Part 1 contains requirements for boilers, pressure vessels, pressure piping, and fittings. It is intended mainly to fulfill two objectives: first, to promote safe design, construction, installation, operation, inspection, testing, and repair practices; and second, to facilitate adoption of uniform requirements by Canadian jurisdictions. b) Part 2 contains requirements for high-pressure cylinders for the on-board storage of natural gas, blends of natural gas and hydrogen (hydrogen blends), and hydrogen as fuels for automotive vehicles. It has been harmonized with International Organization for Standardization (ISO) Standard 11439:2013, Gas cylinders — High pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles. In addition, the CSA Subcommittee responsible for developing Part 2 has consulted with the American National Standards Institute (ANSI) committees responsible for developing CSA/ANSI NGV 2-2016, Compressed natural gas vehicle fuel containers, and CSA/ANSI HGV 2-2014, Compressed hydrogen gas vehicle fuel containers. The members of these two committees are dedicated to harmonizing their standards as far as circumstances allow. c) Part 3 contains requirements for compressed natural gas and hydrogen refuelling station pressure piping systems and ground storage vessels. These requirements have been allotted a separate part of the Standard to emphasize the differences between them and the requirements in Part 1, thereby facilitating their application. This Standard has undergone substantial technical and editorial revisions since the previous edition in 2014. Significant changes to Part 1 include the following: • addition of the following definitions in Clause 3: – "high-energy steam (HES) piping systems"; and – "mechanical joint"; • addition of Clause 4.3.5 on Canadian Registration Numbers (CRNs); • revision of Clause 4.6 on manufacturer’s data reports, including a revised Clause 4.6.1 and a new Clause 4.6.6; • revision of Clause 4.8.2 on fabrication inspection; • deletion of Clause 4.15.1 on general requirements for piping; • revision of Clause 5.1.1 on nameplate stamping; • addition of Clause 6.3.4.7 on boiler installation clearances; • addition of Clause 6.3.6 on boiler loadings; • revision of Clause 6.6 on thermal fluid heaters and piping; • addition of Clause 7.1.5 on the use of Part 5 of Section VIII, Division 2, of the ASME Code; • addition of Clause 7.8 on pressure vessels designed and constructed using cold-stretch technology; • revision of Clause 8 on piping and fittings, including the addition of Clauses 8.6 and 8.7; • addition of Clause 12.1.1 on general requirements for pressure relief devices; • revision of Clause 12.2.2 on the installation of pressure relief devices; • revision of Clause 12.5.3 on periodic visual inspection of pressure relief devices; • revision of Clause 12.7 on servicing of reclosing pressure relief devices, including the addition of Clauses 12.7.2.2 on ANSI/UL 132 pressure relief valves (PRVs) and 12.7.3.2 on testing after servicing is complete; • addition of Clause 12.11 on CSA B149 series propane service pressure relief valves (PRVs); • addition of Clause 13.4 on high-energy steam (HES) piping systems; • revision of Table 5 on maximum in-service testing and service intervals; • revision of Annex C on guidelines for safety valve, relief valve, and safety relief valve repair organizations; • revision of Annex D sample forms; • revision of Annex G on automotive propane vessel standards; • revision of Annex I on historical boilers; • revision of Annex J on requirements regarding the use of finite element analysis (FEA) to support a pressure equipment design submission, including Clause J.3 on special design equipment and Clause J.6.3 on turn angles; • addition of Annex K on requirements for pressure vessels designed and constructed using cold- stretch technology; and • addition of Annex L on condition assessments for high-energy steam (HES) piping systems. Significant changes to Part 2 include the following: • revision of Clause 6.3.2.3 on tensile tests for steel excluding than stainless steel; • revision of Clause 6.3.6 on plastic liners; • revision of Clause 7.3.1 on general requirements for manufacturing and production tests; • revision of Clause 7.4.1 on material tests; • deletion of Clause 8.6.8 on high-temperature creep test; • deletion of Clause 10.7.4 on boss torque test; • revision of Clause 14.13 on ambient temperature pressure-cycling test; • revision of Clause 14.14 on extreme-temperature pressure-cycling test; • revision of Clause 14.16 on penetration test; • revision of Clause 14.17 on flaw tolerance test; • deletion of Clause 14.18 on high-temperature creep test; • revision of renumbered Clause 14.18 on accelerated stress rupture test; • revision of Clause 14.19 on drop test; • revision of Clause 14.21.4 on pressure cycle and pressure hold; and • deletion of Clause 14.24 on boss torque test. The users of this Standard should note that it is a recommendatory document only and does not have the force of law except where it has been officially adopted by a Canadian jurisdiction. Users should also note that adoption does not necessarily mean that the Standard has been adopted unchanged. For example, a jurisdiction may decide to make an informative annex normative. In addition, owners and users of cylinders designed to the requirements of Part 2 should note that the safe operation of such cylinders requires, first, compliance with the service conditions specified by the manufacturer, and second, use of the cylinders only during the service life specified by the manufacturer. Each cylinder is marked with an expiry date, and owners and users are responsible for ensuring that a cylinder is not used after that date. The Technical Committee intends to meet periodically to review this Standard and, if necessary, to revise it to meet changing conditions and maintain uniformity of practice throughout Canada. The Technical Committee supports the use of the National Board Inspection Code. It is the responsibility of users of this Standard to be aware that applicable local regulations can take precedence over the requirements of that Code. 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. -------------------------------------------------------------------------------------------------------------------------------- B51-19, Part 1 - General requirements for boilers, pressure vessels, and pressure piping Scope 1.1 Except as indicated in Clause 1.2, Part 1 of this Standard applies to all boilers, pressure vessels, pressure piping, and fittings, as provided for by the Act (as defined in Clause 3) and identified in Part 1 of this Standard. Notes: 1) It is possible that the size limitations specified in provincial or territorial statutes or regulations will differ from those specified in Part 1 of this Standard. The applicable regulatory authority should be consulted. 2) The pressures specified in Part 1 of this Standard are gauge pressures above atmospheric pressure. 3) This Standard applies to all boilers, pressure vessels, pressure piping, and fittings installed subsequent to its adoption. 1.2 Requirements for compressed natural gas cylinders and refuelling station pressure piping systems and containers are covered in Parts 2 and 3 of this Standard. 1.3 This Standard does not apply to a) pressure-retaining components in hydraulic elevators; b) pressure-containment devices for gas-filled switchgear and controlgear; and c) pressure vessels for the transportation of dangerous goods regulated by Transport Canada. 1.4 Where a clause in Part 1 of this Standard is at variance with a code or standard referenced in Part 1 of this Standard, the requirements of Part 1 of this Standard govern. 1.5 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. 1.6 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. Nominal pipe sizes are expressed in non- dimensional terms. -------------------------------------------------------------------------------------------------------------------------------- B51-19, Part 2 - High-pressure cylinders for the on-board storage of natural gas and hydrogen as fuels for automotive vehicles Scope 1.1 Part 2 of this Standard specifies minimum requirements for serially produced lightweight refillable gas cylinders, both original equipment and conversions, having a water capacity exceeding 20 L (0.71 ft3) but not exceeding 1000 L (35.3 ft3). Part 2 of this Standard applies only to cylinders for the on-board storage of high-pressure compressed natural gas and/or compressed hydrogen as fuels for automotive vehicles to which the cylinders are to be fixed. Cylinders may be of any material (steel, aluminum, or non-metallic) and constructed in accordance with any design or method of manufacture suitable for the specified service conditions. 1.2 The cylinders covered by Part 2 of this Standard are designated as follows: a) Type 1 — metal; b) Type 2 — metal liner reinforced with resin-impregnated continuous filament (hoop-wrapped); c) Type 3 — metal liner reinforced with resin-impregnated continuous filament (fully wrapped); and d) Type 4 — non-metallic liner with resin-impregnated continuous filament (all-composite). 1.3 The service conditions to which the cylinders are subjected are specified in Clause 4. Part 2 of this Standard is based on a working pressure settled at 15 °C (59°F), with a maximum filling pressure of 1.25 times the working pressure. The service life of a cylinder is defined by the manufacturer and can vary with different applications. This Standard’s definition of service life is based on filling a cylinder 750 times a year. The maximum service life of Type 2, Type 3, and Type 4 cylinders is 20 years. For all cylinders, a "safe life" design principle is used. For metal and metal-lined cylinders, the cylinder life is based on the rate of fatigue crack growth. Ultrasonic or equivalent inspection of each cylinder or liner is necessary to ensure that there are no flaws that exceed the maximum allowable size determined by fracture mechanics. This approach optimizes the design and manufacture of lightweight cylinders for natural gas vehicle service. For all-composite cylinders with non-metallic non-load-bearing liners, safe life is ensured by appropriate design methods, design qualification testing, and manufacturing controls. 1.4 Part 2 of this Standard does not cover Type 1 or Type 2 welded metal cylinders or liners. 1.5 Where a clause in Part 2 of this Standard is at variance with codes or standards referenced in Part 2 of this Standard, the requirements of Part 2 of this Standard govern. 1.6 Type 1 steel cylinders may be requalified for further service in accordance with the procedure described in Annex B. 1.7 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. 1.8 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. -------------------------------------------------------------------------------------------------------------------------------- B51-19, Part 3 - Compressed natural gas and hydrogen refuelling station pressure piping systems and ground storage vessels Scope 1.1 1.1.1 The pressure piping systems covered in Part 3 of this Standard are systems used in compressed natural gas (CNG) and hydrogen refueling stations a) between the termination of the utility’s piping, usually at the meter, and the inlet to the compressor assembly if the design pressure exceeds 414 kPa (60 psi); and b) from the inlet to the compressor assembly through to the dispenser nozzle, except for the mechanical parts of the compressor and any subsystems designed for 414 kPa (60 psi) or less. 1.1.2 The ground storage vessels covered in Part 3 of this Standard are pressure vessels that are installed at CNG and hydrogen refueling stations and intended to store CNG or hydrogen at pressure for delivery to vehicle fuel tanks. 1.2 Where a clause in Part 3 of this Standard is at variance with codes or standards referenced in Part 3 of this Standard, the requirements of Part 3 of this Standard govern. 1.3 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.

CSA S16-14 (R2019)

Design of steel structures

Preface This is the eighth edition of CSA S16, Design of steel structures. It supersedes the previous limit states editions published in 2009, 2001, 1994, 1989, 1984, 1978, and 1974. These limit states design editions were preceded by seven working stress design editions published in 1969, 1965, 1961, 1954, 1940, 1930, and 1924. The 1969 working stress design edition was withdrawn in 1984, from which point the design of steel structures in Canada has been carried out using limit states design principles. This Standard is appropriate for the design of a broad range of structures. It sets out minimum requirements and is expected to be used only by engineers competent in the design of steel structures. The following is a list of some of the more important changes made in this edition: a) Clause 1.4 specifically prohibits the use of other standards for fabrication, erection and inspection. b) The definition of “snug-tightness” has been clarified. c) Information required on design documents has been augmented. d) ASTM grades A500/A500M, A1085 and A913/A913M have been added as permissible steel grades for design. e) The fire endurance design requirements have been restated to be in compliance with the NBCC. f) Requirements under impulse loading have been added. g) The initial misalignment of members at brace points has been clarified. h) A calculation for the net area of a slotted HSS member has been given. i) The minimum b/t for bearing stiffeners has been added. j) The clause permitting a joist manufacturer to determine the joist resistance by testing has been removed. k) Provisions for column stiffeners opposite a rigidly connected beam by bolting have been provided. l) Requirements for zinc-aluminum coated assemblies have been incorporated. m) The use of plate washers in lieu of hardened washers is permitted in oversize or slotted holes. n) The use of non-matching electrodes is permitted with reference to W59 for locations where this is permitted. o) Clause 24 that referred to joint surface conditions for field welding in the previous edition has been removed and is now covered in CSA W47.1. p) The factored resistance of anchor rods in bearing has been referred to CSA A23.3 to be consistent with other Canadian design standards. q) A clarification on fatigue calculations has been made to include bending moments due to joint eccentricities. r) An upper limit on the design force of single-storey buildings’ roof diaphragms has been provided. s) A minimum Charpy V-notch value has been specified for weld of primary members and connections. t) A maximum sulfur content for ASTM A913 used in seismic-resisting systems is specified. u) Additional criteria for joint connections have been added to ductile moment-resisting frames, limited ductility moment-resisting frames, and moderately ductile concentrically braced frames. v) The design of link beams for ductile eccentrically braced frames has been expanded. w) Detailing information for limited ductility plate walls has been given. x) Annex K Structural design for fire conditions has been updated. y) The clauses related to pin-connected members have been revised to clarify the net section and resistance requirements. A commentary on this Standard, prepared by the Canadian Institute of Steel Construction with contributions from many members of the Technical Committee, comprises Part 2 of the Institute’s Handbook of Steel Construction. This Standard is intended to be used with the provisions of the 2015 edition of the National Building Code of Canada (NBCC), specifically Clause 7, which references the NBCC for load factors, load combinations, and other loading provisions. Scope and application 1.1 General This Standard provides rules and requirements for the design, fabrication, and erection of steel structures. The design is based on limit states. The term "steel structures" refers to structural members and frames that consist primarily of structural steel components, including the detail parts, welds, bolts, or other fasteners required in fabrication and erection. This Standard also applies to structural steel components in structures framed in other materials. The clauses related to fabrication and erection serve to show that design is inextricably a part of the design-fabrication-erection sequence and cannot be considered in isolation. For matters concerning standard practice pertinent to the fabrication and erection of structural steel not covered in this Standard, see Annex A. 1.2 Requirements Requirements for steel structures such as bridges, antenna towers, offshore structures, and cold-formed steel structural members are given in other CSA Group Standards. 1.3 Application This Standard applies unconditionally to steel structures, except that supplementary rules or requirements might be necessary for a) unusual types of construction; b) mixed systems of construction; c) steel structures that i) have great height or spans; ii) are required to be movable or be readily dismantled; iii) are exposed to severe environmental conditions; iv) are exposed to severe loads such as those resulting from vehicle impact or explosion; v) are required to satisfy aesthetic, architectural, or other requirements of a non-structural nature; vi) employ materials or products not listed in Clause 5; or vii) have other special features that could affect the design, fabrication, or erection; d) tanks, stacks, other platework structures, poles, and piling; and e) crane-supporting structures. 1.4 Other standards The use of other standards for the design, fabrication, erection, and/or inspection of members or parts of steel structures is neither warranted nor acceptable except where specifically directed in this Standard. The design formulas provided in this Standard may be supplemented by a rational design based on theory, analysis, and engineering practice acceptable to the regulatory authority, provided that nominal margins (or factors) of safety are at least equal to those intended in the provisions of this Standard. The substitution of other standards or criteria for fabrication, erection, and/or inspection is expressly prohibited unless specifically directed in this Standard. 1.5 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.


CAN/CSA Z94.4-2018

Selection, use, and care of respirators

Preface   This is the fifth edition of CAN/CSA-Z94.4, Selection, use, and care of respirators. It supersedes the previous editions published in 2011, 2002, 1993, and 1982.   This Standard sets out requirements for the selection, use, and care of respirators and for the administration of an effective respiratory protection program in the workplace. Its purpose is to protect respirator users from any known or potential respiratory hazards. In 2017, CSA Group completed a research project that gathered evidence to verify the bioaerosol protection factors set out in this Standard as well as the control banding approach for selection of respiratory protection against infectious bioaerosols (Clause 7.3.4.3).   This Standard is based on respirator classification schemes and testing requirements set out by the National Institute for Occupational Health and Safety (NIOSH). Specific criteria for firefighting applications are based on standards published by the National Fire Protection Association (NFPA).   CSA Z180.1 is a companion Standard to CAN/CSA-Z94.4, providing specific requirements for compressed breathing air systems connected to supplied-air respirators. This Standard is also referenced by many other CSA Group occupational health and safety standards where respiratory protection is required (e.g., CSA W117.2 on welding safety, CSA Z1006 on work in confined spaces, CSA Z1010 on work in extreme conditions, CAN/CGSB/CSA-Z1610 on protection of first responders, and CSA Z1640 on PPE for entry into clandestine drug labs).   A number of significant changes have been introduced in this edition of the Standard:   a) Clarification has been made regarding the supervisor?s role in a respiratory protection program (Clause 5.3).   b) Clause 6 has been re-ordered to clarify how hazard assessment and risk assessment are to be used as the basis for selection of appropriate respirators (especially in situations where both air contaminants and bioaerosols are present).   c) Several clarifications have been provided regarding requirements for initial and subsequent periodic training (Clause 8.2.5).   d) Additional guidance has been provided on the handling of respirator interference concerns (Clause 9.2).   e) Clause 12, on health surveillance, has been modified to clarify the point that a health assessment is needed prior to fit testing and that there may be medical reasons for not subjecting an individual to a fit test.   f) The wearer?s comfort has been made a significant factor in selection of respirators and fit testing (see Clause 14.4 and expanded Annexes B and C).   g) Annex K, providing scenarios for bioaerosol exposure situations, has been significantly expanded.   h) A new Annex (N) has been added to provide guidance on measurement of bioaerosols and determining exposure limits.   i) A new Annex (O) has been added to provide information on the persistence of bacteria, fungi, viruses, and other pathogens on surfaces and in air.   j) A new Annex (Q) has been added to provide guidance on accommodation of individuals having special needs.   k) A new Annex (R) has been added to provide further guidance on the records required to be maintained for both qualitative and quantitative fit testing (Clause 14.4).   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.   Scope   1.1 This Standard sets out requirements for the selection, use, and care of respirators and for the administration of an effective respiratory protection program in the workplace.   1.2 This Standard is applicable to the selection, use, and care of respirators for non-emergency and emergency situations.   1.3 This Standard is not intended to address the selection of   a) respirators for aircraft oxygen systems;   b) supplied-air suits; or   c) respirators for protection against radiological contaminants.   This Standard applies to all other aspects of a respiratory protection program for these respirators.   1.4 This Standard is not intended to address   a) underwater breathing devices (see CSA Z275.2);   b) requirements for protection for first responders during CBRN (chemical, biological, radiological, and nuclear) events (see CAN/CGSB/CSA-Z1610); or   c) inhalators and resuscitators.   1.5 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.   1.6 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.
