You can find the Occupational Health & Safety regulation details for Northwest Territories here.
Please look at 97(1-4) which currently reads:
“Eye and Face Protection 97. (1) If there is a risk of irritation or injury to the face or eyes of a worker from flying objects or particles, splashing liquids, molten metal or ultraviolet, visible or infrared radiation, an employer shall provide and require the worker to use an approved industrial eye protector or approved face protector to eliminate or reduce the risk. (2) An employer shall take all reasonable steps to ensure that a worker does not perform electric arc welding if another worker could be exposed to radiation from the arc, unless the other worker is using an approved industrial eye protector or is protected from the radiation by an approved screen. (3) A worker shall not perform electric arc welding if another worker could be exposed to radiation from the arc, unless the other worker is using an approved industrial eye protector or is protected from the radiation by an approved screen. (4) A worker who is required by these regulations to use an industrial eye protector or face protector shall not wear contact lenses.”
Under the definitions of the Safety Act it defines “Approved” as “approved by the Chief Safety Officer in a code of practice approved and issued under subsection 18(3) of the Act; (approuvé)”.
The specific codes of practice can be found on the Northwest Territories’ Workers Safety and Compensation Commission website.
The specific code of practice for Eye and Face Protection PPE is listed and can also be found here.
In short: CSA Z94.3-20 (the 2020 version) along with Z94.3.1-16 (the guidelines for selection, use and care of protective eyewear) are the standards that should be used for safety eyewear in Northwest Territories.
