2 The CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this standard has been developed, is a government agency within Public Works and Government Services Canada. CGSB is engaged in the production of voluntary standards in a wide range of subject areas through the media of standards committees and the consensus process. The standards committees are composed of representatives of relevant interests including producers, consumers and other users, retailers, governments, educational institutions, technical, professional and trade societies, and research and testing organizations. Any given standard is developed on the consensus of views expressed by such representatives. CGSB has been accredited by the Standards Council of Canada as a national standards-development organization. The standards that it develops and offers as National Standards of Canada conform to the criteria and procedures established for this purpose by the Standards Council of Canada. In addition to standards it publishes as National Standards of Canada, CGSB produces standards to meet particular needs, in response to requests from a variety of sources in both the public and private sectors. Both CGSB standards and CGSB national standards are developed in conformance with the policies described in the CGSB Policy and Procedures Manual for the Development and Maintenance of Standards. CGSB standards are subject to review and revision to ensure that they keep abreast of technological progress. CGSB will initiate the review of this standard within five years of the date of publication. Suggestions for their improvement, which are always welcome, should be brought to the notice of the standards committees concerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards. An up-to-date listing of CGSB standards, including details on latest issues and amendments, and ordering instructions, is found in the CGSB Catalogue at our Web site Ñ along with more information about CGSB products and services. 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. The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. CGSB neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed. Attention is drawn to the possibility that some of the elements of this Canadian standard may be the subject of patent rights. CGSB shall not be held responsible for identifying any or all such patent rights. Users of this standard are expressly advised that determination of the validity of any such patent rights is entirely their own responsibility. Language In this Standard, ÒshallÓ states a mandatory requirement, ÒshouldÓ expresses a recommendation and ÒmayÓ is used to express an option or that which is permissible within the limits of this 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.

Further information on CGSB and its services and standards may be obtained from: The Manager Standards Division Canadian General Standards Board Gatineau, Canada K1A 1G6 The Standards Council of Canada (SCC) is the coordinating body of the Canadian standardization network, which is composed of people and organizations involved in the development, promotion and implementation of standards. Through the collaborative efforts of Canadian standardization network members, standardization is helping to advance the social and economic well-being of Canada and to safeguard the health and safety of Canadians. The networkõs efforts are overseen by SCC. The principal objectives of SCC are to foster and promote voluntary standardization as a means of advancing the national economy, supporting sustainable development, benefiting the health, safety and welfare of workers and the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international cooperation in relation to standardization. An important facet of the Canadian standards development system is the use of the following principles: consensus; equal access and effective participation by concerned interests; respect for diverse interests and identification of those who should be afforded access to provide the needed balance of interests; mechanism for dispute resolution; openness and transparency; open access by interested parties to the procedures guiding the standards development process; clarity with respect to the processes; and Canadian interest consideration as the initial basis for the development of standards. A National Standard of Canada (NSC) is a standard prepared or reviewed by an SCC-accredited SDO and approved by the SCC according to NSC approval requirements. Approval does not refer to the technical content of the standard, as this remains the responsibility of the SDO. An NSC reflects a consensus of a number of capable individuals whose collective interests provide, to the greatest practicable extent, a balance of representation of general interests, producers, regulators, users (including consumers) and others with relevant interests, as may be appropriate to the subject at hand. NSCs are intended to make a significant and timely contribution to the Canadian interest. Those who have a need to apply standards are encouraged to use NSCs. These standards are subject to periodic review. Users of NSCs are cautioned to obtain the latest edition from the SDO that publishes the standard.

7 Supersedes CAN/CGSB and part of CAN/CGSB Fireline workwear for wildland firefighters 1 Scope This National Standard of Canada applies to the minimum requirements for performance of fireline workwear used for the protection against the adverse effects to the firefighter s body during wildland firefighting, or prescribed fire operations. It also provides guidance for the selection, use, maintenance and retirement of such workwear and for understanding its limitations. This standard establishes performance requirements and test methods for evaluation of components used to construct workwear. Workwear meeting this standard is intended to provide a degree of protection against the adverse effects of fire to the firefighter s body during wildland firefighting. For the purposes of this standard, protective does not mean that a wearer will suffer no burns if exposed to fire while wearing workwear meeting this standard. Protective garments may serve to reduce the severity of burn injury as a result of exposure to a wildfire but may not completely prevent an injury. Garments that continue to burn after a fire incident are hazardous. CAN/CGSB was developed to minimize this hazard. This standard refers to workwear that will be worn as the outermost garment. This standard refers to single-layer or multi-layer protective garments that cover the body from the neckline to the wrists and ankles, and shall cover the neck when necessary. The use of workwear for protection against the adverse effects of fire to the firefighter s body during wildland firefighting should be incorporated into an appropriate safety program that also utilizes appropriate administrative and engineering controls in addition to proper safe work procedures. This standard does not apply to specialized protective clothing such as proximity suits, structural firefighters protective clothing, workwear for protection against hydrocarbon flash fire and fire-entry clothing. It is not intended to establish requirements for protection from chemical, radiological, electrical, nuclear or biological hazards. The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This standard does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. 2 Normative references The following normative documents contain provisions that, through reference in this text, constitute provisions of this National Standard of Canada.

NOTE Accessories may include: radio, harness, belt, backpack and fanny pack. 3.2 collar part of a garment that is attached to the body of the garment at the neckline and covers or partially covers the neck. 3.3 crest small cloth badge affixed to a garment as organization identification or an insignia. NOTE May also be referred to as a patch, flash, or emblem. 3.4 cuff finished edge of a sleeve, usually comprising at least a double layer of fabric sewn to the end of the sleeve material and closing around the wrist. 3.5 decontamination removal of contaminant(s) from the clothing, usually by laundering or dry cleaning. 3.6 drip to run or fall in drops or blobs. 3.7 ease the difference between garment and body dimensions. 3

10 NOTE In most materials, appropriate ease is necessary to allow good fit and to facilitate natural body movement and performance of any task while wearing a garment. 3.8 fabric any material woven, knitted, crocheted, knotted, braided, felted, bonded, laminated or otherwise produced from, or in combination with, a textile fibre. 3.9 fabric mass mass per unit area in g/m fibre fibre is considered the basic component or building block of a textile product; although most fibres are normally composed of even smaller units called polymers, the fibre is the smallest unit we can see without the aid of a microscope. NOTE Fibres are classified as manufactured or natural fibres. To produce textiles, fibres are usually spun into yarns which are then woven or knit into fabrics. Fibres can also be made directly into fabrics through processes such as felting. The structure and basic properties of component fibres have considerable influence on the performance of a textile material or product fire (noun) process of combustion characterized by the emission of heat accompanied by smoke and/or flame fireline workwear protective workwear such as, but not limited to, coveralls, trousers and shirts, designed to provide a degree of protection against the adverse effects of fire and radiant heat to the firefighter s body during wildland firefighting. Fireline workwear covers the body from the neck to the wrists and ankles and may or may not completely cover the neck. It does not include add-on accessories, such as, but not limited to belts, backpacks and external harnesses flame (noun) zone of combustion in the gaseous phase with emission of light flame (verb) to undergo combustion in the gaseous phase with emission of light flame-retardant treatment process or treatment whereby flame resistance characteristics are imparted to a fabric or other component flame resistance / flame resistant (FR). property of a material whereby flaming combustion is slowed, terminated or prevented. NOTE Flame resistance can be an inherent property of the basic fibre material, or can be imparted by a specific treatment or additive generic name name given to a class of fibres with similar chemical makeup, as defined in the Textile Labelling and Advertising Regulations, made under the Textile Labelling Act. 4

11 3.18 hardware non-fabric items used in protective workwear, including those made of metal or plastic material. NOTE Hardware includes, but is not limited to buttons, snaps and zippers heat transfer printing technique of printing fabrics by transferring a printed design from paper to fabric via heat and pressure, while having the characteristics of being flexible enough for stretching and durable enough for wearability inherently flame-resistant as applied to textiles, having flame resistance that derives from an essential characteristic of the polymer or other material from which the fibre is made interfacing textile inserted between the fabric and the lining of part of a garment to reinforce that part and give it more body. NOTE An example is the interfacing in a shirt collar knitted fabric structure produced by interlooping one or more sets of yarns or comparable material. NOTE Examples are jersey, rib, interlock label identifying or descriptive piece of fabric attached to the garment for the purpose of providing information (see 7) major A seams those seam assembly constructions where rupture exposes the wearer to immediate danger major B seams those seam assembly constructions where rupture could reduce the protection of the garment by exposing the next layer of the garment, undergarment, or other clothing manufactured fibres group of fibres that may be either synthesized from chemical compounds (synthetics) or regenerated from natural components. NOTE Examples of synthetic fibres by generic name are aramid, nylon, and polyester. Examples of regenerated fibres are viscose and other rayons melt physical process of changing from solid to liquid by the action of heat, resulting in irreversible change, as evidenced by flowing or dripping. 5

12 3.28 multilayer garment garment consisting of an outer shell fabric plus an inner lining fabric, a wind/moisture barrier and/or insulating material. A multilayer garment can be separated easily into its major constituent components natural fibres group of fibres in which the basic constituent materials are (1) animal (e.g., silk & wool), (2) mineral (e.g., glass), or (3) vegetable (e.g., cotton & flax) prescribed burn knowledgeable application of fire to a specific land area to accomplish predetermined forest management or other land use objectives prescribed fire any fire utilized for prescribed burning; usually ignited according to agency policy and management objectives primary closures all closures excluding those at the wrists, ankles, throat and underarms radiant heat resistance (RHR) cumulative amount of thermal exposure energy identified by the intersection of the measured time-dependent heat transfer response through the subject material to a time-dependent, empirical performance curve, expressed as a rating or value; kj/m 2. NOTE The higher the RHR value, the higher the level of protection provided reinforcement fabric or material enhancement applied to a specific area to make it more resistant to wear. NOTE Examples of specific areas include elbows, knees, seat, etc seam any method of permanently joining two or more pieces of textile material single-layer garment protective garment constructed from a single fabric (not including facing or interfacing). A single layer garment is one that cannot be easily separated into its major constituent components. NOTE Fabric material for a single layer garment is received in a finished state from the fabric supplier or finisher. Garments made from bonded fabrics, laminated fabrics, coated fabrics, double cloth, and quilted fabrics, for example, are considered single layer garments screen printing technique that uses a woven mesh to support an ink-blocking stencil. The attached stencil forms open areas of mesh that transfer ink or other printable materials which can be pressed through the mesh as a sharp-edged image onto a substrate. A roller or squeegee is moved across the screen stencil, forcing or pumping ink past the yarns of the woven mesh in the open areas. 6

13 3.38 thermal protection/thermal protective performance (TPP) measurement of the thermal energy input from a flame source to a fabric specimen that is required to result in a heat transfer through the specimen sufficient to cause second-degree (partial-thickness) burn in human tissue. NOTE The higher the TPP, the higher the level of protection provided visibility trim retroreflective, fluorescent, or combination retroreflective and fluorescent material attached permanently to the outer material for visibility enhancement. NOTE Retroreflective materials enhance night time visibility, and fluorescent materials improve day time visibility wildfire (wildland fire) unplanned or unwanted natural or human-caused fire, that is burning in forested areas, grass or other vegetation wildland firefighting activities of fire suppression and property conservation in vegetation that is not within structures, but that is involved in a fire situation woven fabric woven fabrics consist of interlaced yarns that normally are perpendicular to each other. Yarns running lengthwise are called warp yarns. Yarns running across the width of the fabric are called filling or weft yarns. Woven fabrics may vary in texture and appearance based on variations in the interlacement of yarns.

21 Annex A (informative) Selection and sizing of fireline workwear A.1 It is very important to train firefighters in the selection, use, care and maintenance of the workwear. The fireline workwear should provide a good functional fit for maximum protection, functionality and comfort on the job. Users should be aware that the fit of a garment can have a direct influence on how much thermal protection it can provide. A garment that is tight fitting poses a danger to the wildland firefighter from radiant heat and heat stress, while at the same time, diminishing the firefighter s ability to perform. A looser fit with controlled fullness (i.e., fitting more closely at waist, wrist and ankles) is likely to provide better thermal protection and be more comfortable. A.2 Selection of fireline workwear A.2.1 The selection of fireline workwear should be based on the evaluation of specific criteria applicable to the particular occupational situation. This evaluation should be determined by safe work procedures, industry standards and occupational health and safety regulations. The evaluation should include consideration of the following parameters: potential hazards the workers may be exposed to in the course of their duties; hazard classification of the work area (for example, the presence of other types of hazards, such as chemical); factors affecting durability or wear life (for example, UV degradation); physical demands of the work; climate; access to service such as laundering/dry cleaning, repair establishments; supplier services (for example, inventory of garments/fabric/fibre, quality assurance level, technical assistance, industry experience). A.2.2 The relative importance of each of the criteria should be determined before deciding on the optimum combination of fabric/garment properties and performance requirements for a specific job or a combination of duties. A.2.3 Additional selection criteria which may be useful in evaluation of workwear could include: visibility trim, comfort, characteristics of fabric labels, emblems and crests, fit, tearing strength, breaking strength of fabric, abrasion resistance, pilling, chemical resistance, dimensional change, colourfastness to sunlight, colourfastness to laundering or dry cleaning, moisture properties, and static electricity properties. A.3 Sizing of garments To provide proper fit for firefighters, the charts in Tables A1 to A4 can be followed by wildland fire agencies for ordering garments. Measurement procedures and the designation of body dimensions should correspond to ISO

For example, a Medium Regular Coverall is meant to fit a person with a chest size of cm; thus the garment must be a minimum of 125 cm around the chest to meet the minimum ease requirement of 15 cm. 19

26 Annex B (informative) Use of fireline workwear B.1 For maximum protection, the protective workwear should be worn properly. The collar should be worn closed, and sleeves and cuffs worn down, and secured. B.2 Protective neck, head, hand and foot coverings should be worn if the occupational hazard warrants their use. B.3 Certain synthetics or synthetic blend garments may not be appropriate for use under fireline workwear, as the transferred heat from a fire may cause them to melt. Any garment worn under the protective garment should have melt-resistant properties. 20

27 Annex C (informative) Maintenance of fireline workwear C.1 Fireline workwear must be kept clean. Adequate decontamination of fireline workwear, according to the manufacturer s recommendations, by laundering or dry cleaning is imperative in order to maintain flame resistance and thermal protection. Soiling may reduce the protective qualities and increase the risk of second- and third-degree burns. Garments that are contaminated with a significant amount of oily soil or a flammable substance should be decontaminated (or cleaned) to remove the substance. If garment cannot be cleaned, it should be removed from service. C.2 Protective garments require frequent cleaning to prevent the build-up of hard to remove stains that could reduce their flame resistance. Pre-treat oily stains by either rubbing liquid detergent or powdered detergent mixed with water into the stain or use a pre-wash product recommended for oily stains. Use a heavy duty liquid or powdered laundry detergent and the hottest water recommended on the garment label. It is harder to remove oily soil with cool wash water, but the recommended temperature should not be exceeded. C.3 Note any laundry precautions on the garment label which will lessen the effectiveness of the flame resistance, in particular: a. whether the use of chlorine bleach is advised or should be avoided; b. whether a heavy duty soap can be used or laundering must be limited to a heavy duty synthetic detergent. c. whether the use of fabric softener is advised or should be avoided. C.4 Some soaps and detergents can adversely affect the flame-resistant properties of the garment. The user should check with the manufacturer of the garment for appropriate cleaning instructions. Certain petroleum solvents should be avoided as they commonly leave a flammable grease deposit and reduce protective properties. C.5 Periodically, a selection of garments should be removed from use, inspected and tested to the performance requirements of this standard, so the user can make a decision on continued use or disposal. C.6 Visual inspection of garments should include, but is not limited to: a. holes, cut, tears, or torn seams; b. buttonholes - frayed or broken stitching; c. missing buttons; d. hook and loop fastener missing or that is defective, does not provide adequate closure and has broken stitching (wrist/neck/pocket area); e. broken stitches or fading on the crests; f. hardware defects (non-fabric items: fasteners, crests, buttons, etc.); g. zippers - broken or missing slider; h. belt loops - missing or broken; i. pockets - torn or frayed; j. ensuring no contaminants are present (staining). 21
