Canadian law says that every employee has the right to know about anything that is hazardous and anything that will effect their safety and health in their work place.
For example, every employer must inform their employees on what to do in case their is fire in the building.
It doesn't really matter if you work in a 1 level warehouse or in a 50 floors building.
Same thing applies to employees who work in a warehouse that use hazardous chemicals.
I personally used to work at a chemical place where they used to dip airplane parts so that they don't rust.
There were many chemicals and processes that those parts went through.
One of the things that my supervisor told me when I got started working there were all the health and safety rules that I needed to know about the place.
They made sure that every employee knew the health and safety rules there.
Many places, like the one I used to work in, must know everything when it comes to their own health and safety rules.
Like where you can wash you face or eyes should any of the chemicals jump in your face.
Who to inform when this happens to you.
I, as an employee, also had the right to know if I will get paid should I get hurt on the job site.
If the employer fails to inform the employees about these things, they can end up being fined for their inaction of letting all employees know safety issues and rights.
When an employer fails to inform its employees and something happens to one of them without them knowing their rights, the employer can be fined.
It is as simple as that.
Also, not investing money in the tools and resources that keep employees safe can cost them more money in the long run.
Companies and employers who do not follow these rules and break the law can not only expect huge fines, but they can also be sued by any or all of their effected employees.
So, employers must follow the law and inform their employees about health and safety policies.
