Industrial protective headwear - Performance, selection, care, and use

Preface This is the sixth edition of CSA Z94.1, Industrial protective headwear - Performance, selection, care, and use. It supersedes the previous editions published in 2005, 1992, 1977, and 1966 under the title Industrial Protective Headwear. It also supersedes the Preliminary Standard published in 1965 and replaces the protective headwear requirements specified in CSA Z94-1948, Code for Head and Eye Protection. This edition incorporates several changes: a) A "protected area" has been established through the specification of a test line on the headform used for impact and penetration tests (Clauses 6.3.1,, 10.2.5, 10.3.6, and Figure 2). b) Technical changes have been made to penetration test procedure and apparatus (Clause 7.4.6). c) The largest size of headform (size "O") is no longer specified for testing purposes (Clause 7.4.7). d) The UV resistance requirements and pre-conditioning procedure have been removed pending future research to validate the procedure against real-use conditions (exposure to sunlight). e) Clarification of symbols used on labels has been provided (Annex C). f) An explanation of the difference between accredited product certification and a manufacturer's self-declaration of compliance has been provided (Annex C). Wearing protective headwear that meets the requirements of this Standard will reduce the likelihood of injuries to the head. It should be noted, however, that there is a limit to the amount of protection provided by such headwear. It remains the responsibility of the users of this Standard to judge a headwear product's suitability for their particular purpose and to ensure the compatibility of their headwear with associated equipment, e.g., hearing protection devices. Users should consult applicable occupational safety regulations to determine whether they impose safety requirements in addition to or more stringent than those in this Standard. Scope 1.1 This Standard applies to protective headwear for industrial, construction, mining, utility, and forestry workers. It defines the areas of the head that are to be protected and includes basic performance requirements for dielectric strength, impact attenuation, penetration resistance, passive retention (stability), and shell flammability and liner ignition resistance. 1.2 This Standard includes requirements for and provides guidance on the selection, care, and use of protective headwear. 1.3 The tests specified in this Standard set minimum performance requirements for protective headwear but do not cover other design factors such as comfort, service life, or appearance. Note: Compliance with the requirements of this Standard does not imply equality of performance among different types of protective headwear, nor should it be interpreted to mean that a headwear product is capable of affording greater protection than is specified in this Standard. 1.4 This Standard does not apply to "bump caps", firefighting helmets, rescue helmets, crash helmets, sports and recreation helmets, or riot control helmets. 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.
