Preface

This is the fifth edition of CSA W117.2, Safety in welding, cutting, and allied processes. It supersedes the previous editions published in 2001, 1994, 1987, and 1974. Its subject is the health and safety of welders and welding operators. The safe design of welding equipment is covered in other Standards that are referenced in this document.

1.4 Terminology

In CSA Standards, "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; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability. 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.
