This is the second edition of CSA Standard CAN/CSA-Z321, Signs and Symbols for the Workplace. It supersedes the first edition, titled Signs and Symbols for the Occupational Environment, published in 1977.
This Standard applies to signs intended for use in the workplace for the purpose of communicating a regulatory, warning or informational message with the emphasis on safety and/or health. It describes requirements for the design of signs and includes recommendations for their selection and placement.
This Standard also includes requirements for signs that are not specifically safety- and/or health-oriented but are often part of the workplace.
The use of these signs does not replace the need for other proper accident-prevention measures.
This Standard does not apply to signs used to identify
(a) the actual or potential presence of ionizing radiation;
(b) objects, devices, materials, or combinations of materials that emit ionizing radiation;
(c) product labelling;
(d) hazardous materials (as defined by the Workplace Hazardous Materials Information System);
(e) dangerous goods being transported; and
(f) emergency exits (as defined by the Building Code).
For guidance pertaining to the use of signs and symbols in the barrier-free design of buildings, readers should refer to CSA Standard B651.
