CAN/CGSB-155.20-2017

This National Standard of Canada states the minimum requirements and test methods for performance of protective workwear worn for protection against unplanned exposure to hydrocarbon flash fire and optionally steam and hot fluids. This standard applies to newly manufactured (ie. unworn) protective workwear that individually, or as a component of an ensemble, covers the body from the neckline to the wrists and ankles and may cover the head and neck. The performance requirements of this standard are not representative of all hazards to which personnel can be exposed. Controlled laboratory tests shall not be interpreted as hazard simulations. Protective workwear meeting this standard is intended to provide a degree of protection to the wearer, reduce the severity of injury and not contribute to injury during an exposure to flash fire, steam or hot fluid. Protective workwear may not be sufficient to completely prevent burn injury. This standard applies to garments manufactured on or after the publication date of the standard. This standard provides minimum requirements and does not prevent or preclude performance in excess of the minimum level specified. This standard also contains an informative annex which provides guidance for the selection, use, maintenance, retirement, and understanding of the limitations of protective workwear (see Annex B). Additionally, the issue of fit of the protective workwear on the user is addressed. The use of protective workwear should be incorporated into an appropriate safety program that also utilizes appropriate hazard assessments and engineering and/or administrative controls in addition to appropriate safe work procedures. This standard does not apply to specialized protective clothing such as proximity suits, firefighters’ protective clothing and fire-entry clothing. It is not intended to establish requirements for protection from chemical, biological, radiological, nuclear, mechanical, or electrical 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 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.
