This is the first edition of CSA Z1005, Incident investigation. This Standard replaces CAN/CSA-Z796, Accident information, published in 1998.
This Standard outlines incident investigation and prevention principles and requirements, the purpose of which is to determine causes and to prevent work-related incidents. As used in this Standard, the term incident refers to an occurrence, condition or situation arising in the course of work that resulted in, or could have resulted in, injury, illness, damage to health, or fatality. As used in this Standard, the term data refers to information collected during an incident investigation for reference or analysis.
CSA Z1005 adheres to management system principles, such as those set out in CSA Z1000, Occupational health and safety management. Use of Z1005 is not contingent on an organization having an occupational health and safety management system (OHSMS); however, it does specify a Plan-Do-Check-Act cycle to ensure that management system deficiencies are identified and addressed.
CSA Z1005 also complements CSA Z1002, Occupational health and safety – Hazard identification and elimination and risk assessment and control. When hazards are identified and eliminated, and when risk is assessed and controlled in accordance with the principles in CSA Z1002, then the number of work- related incidents can be reduced or prevented. CSA Z1005 encourages the use of these investigative principles as a prevention tool. Principles in this standard are designed to be used before, during, or after an event to effectively respond to – or ideally, proactively eliminate – that event, similar events, or other safety deficiencies identified during the investigation, taking investigative principles beyond the traditional approach. The principles of this Standard are intended to be scalable.
This Standard specifies requirements for an occupational health and safety (OHS) incident investigation and prevention program (IIPP).
This Standard can be applied by organizations of any size or type.
This Standard is intended to address investigations related to occupational health and safety.
This Standard does not specify requirements for criminal or regulatory enforcement investigations.
1) The investigation principles of this standard can be applied to non OHS investigations such as environmental incidents.
2) Some investigations will involve, or evolve into, a criminal or regulatory investigation. Organizations need to plan for this possibility.
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 it 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.
