Safety Glasses in the Canadian Workplace
The use of proper eyewear or face-wear for protection against workplace hazards is an important topic in Canadian occupational health and safety. To protect workers’ face and/or eyes against workplace elements, Canadian employers must have a standard of safety eyewear that is specific to their company or line of work. That standard may be the use of full face shields on the job-site to safety glasses that can fulfill a number of eyewear protection needs. The proper eyewear or face protection is determined by the type of workplace dangers that are present on your jobsite. Canadian employers must provide workers with the training and maintenance regarding safety eyewear; although many employers supply safety eyewear it is the workers responsibility to pay for the safety eyewear. With this in mind, how does a worker recognize safety glasses on the job site? What are the distinguishing characteristics?
Workers wearing prescription lenses must ensure that the glasses they choose meets the Canadian Standards Association (CSA) Standards. Also, workers wearing contact lenses must be aware of additional hazards and have prescription safety glasses when required.
The Canadian Standards Association (CSA) outlines the following:
Lenses: Safety glasses that are CSA-certified must have plastic polycarbonate lenses. Polycorbonate is defined as having a stronger material than regular plastic lenses. These type of lenses are impact-resistant and can be manufactured as regular and prescription types.
Frames: Safety glasses frames that are CSA-certified are noted as being stronger and more durable than the types of frames found in regular glasses. The frames are typically heat resistant as well. Importantly, a typical safety glasses frame will be designed in a manner that reduces the chance for the lens to be pushed into the wearer’s eye during moments of impact.
Safety Glass Lens Colour
If you’ve spent any amount of time on a jobsite, you’ll quickly notice that there are a number of safety glasses’ lens colours to choose from. From yellow to blue, lens colours are very specific to the type of job and work environment that you are involved in; therefore, what should you know about choosing the colour of safety glass lenses? The chart below outlines the colour differences in lenses.
Face Shields / Face Wear
Face shields are an extension of eye-protection where the entire face must be protected from a number of external dangers, including: impact, electrical, chemical splashes, heat, radiation, dust & debris.
The topic of eye wear on the job site is detailed in its scope. For a complete reference on the topic of eyewear safety from a Canadian perspective, please refer to the Canadian Centre for Occupational Health and Safety and the section dedicated to Safety Glasses and Face Protectors.
