Thank you for your question.
If I understand correctly, your concern is with regard to the clarification of the definition of danger and whether or not it continues to provide protections to employees with respect to impacts upon life or health that are longer-term.
The clarified definition does cover that. We're talking about imminent or serious impact to life or health. So if in a workplace employees are not provided with the proper training, the proper protective equipment, and the proper procedures to handle certain substances that could have a serious impact on life or health, whether it is immediate or longer-term, it is still covered within the clarified definition of danger.
Again, just to reiterate, there is no change to the right of an employee to refuse to work. If an employee has a reasonable belief that there is a danger to their life or health, they are able to refuse to work, and to continue to refuse to work, until there is a resolution.
