Scope 1.1 InclusionsThis Standard specifies the requirements to address occupational health and safety (OHS) incident investigation and prevention program (IIPP). This Standard can be applied to inform investigations by organizations in any type of industry of any size. 1.2 ExemptionsThis Standard does not specify requirements for criminal or regulatory enforcement investigations. Notes: 1) The investigation principles of this Standard can be applied to non-OHS investigations, such as environmental incidents. 2) Some investigations can involve, or evolve into, a criminal or regulatory investigation. Organizations need to plan for this possibility. 1.3 TerminologyIn 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.
