REGDOC-2.2.1, Human Factors
This regulatory document is part of the CNSC’s human performance management series of regulatory documents, which also covers personnel training, personnel certification and fitness for duty. The full list of regulatory document series is included at the end of this document and can also be found on the CNSC’s website.
Regulatory document REGDOC-2.2.1, Human Factors, describes how human factors are taken into consideration in the CNSC’s regulatory activities.
This document supersedes guidance document P-119, Policy on Human Factors, published in July 2000.
Note: In 2013, the CNSC adopted a revised regulatory framework structure with a new system for naming and numbering regulatory documents. This document has been published as part of the CNSC’s initiative to bring regulatory documents that were published before the current framework was adopted into the new system. The requirements and guidance in this document have not changed.
For information on the implementation of regulatory documents in the licensing basis, and on the graded approach, see REGDOC-3.5.3, Regulatory Fundamentals.
The words "shall" and "must" are used to express requirements to be satisfied by the licensee or licence applicant. "Should" is used to express guidance or that which is advised. "May" is used to express an option or that which is advised or permissible within the limits of this regulatory document. "Can" is used to express possibility or capability.
Nothing contained in this document is to be construed as relieving any licensee from any other pertinent requirements. It is the licensee’s responsibility to identify and comply with all applicable regulations and licence conditions.

2. Definition and Examples of Human Factors
For purposes of this regulatory document, the term "human factors" means factors that influence human performance as it relates to the safety of a nuclear facility or activity over all phases, including design, construction, commissioning, operation, maintenance and decommissioning.
Some examples of human factors are: organizational and management structures, policies and programs; the allocation of functions to humans and machines; the design of user interfaces; staffing provisions; job-design features; work schedules; the design of written procedures; training, and the physical work environment.
3. The CNSC’s Approach to Human Factors
The CNSC recognizes that human factors can affect the performance of the facilities and activities that it regulates:
- When reviewing applications for CNSC licences in accordance with any applicable laws, procedures and guidelines, the CNSC takes into account human factors that could impact the CNSC’s mandate for protection of the environment, the health and safety of persons, the maintenance of national security and the implementation of international obligations to which Canada has agreed.
- The CNSC evaluates the measures proposed by licence applicants, and the measures implemented by licensees to address human factors, to determine whether the measures provide for protection of the environment, the health and safety of persons, the maintenance of national security and the implementation of international obligations to which Canada has agreed.
- The CNSC provides, where needed, licence applicants and licensees with written guidance on how to address human factors that could affect the safety of CNSC-regulated facilities and activities.
- The CNSC cooperates with other organizations and jurisdictions to foster consistent national and international standards with respect to human factors.
