Q.
What are the goals of the Worker Exposures to Chemical Agents in the Workplace
campaign:
A.
Ensure compliance with R.R.O. 1990, Regulation 833: Control of Exposure to Biological or
Chemical Agents in all workplaces where this regulation applies.
More specifically, MLITSD hygienists will ensure that workers are not exposed to hazardous
substances exceeding the occupational exposure limits.
Assess worker exposures by identifying the hazards, observing work practices, evaluating
effectiveness of controls.
Existing exposure data will be reviewed and/or a requirement for air sampling may be issued.
Contribute to the development of an exposure surveillance system.
Q.
What are the goals for WHMIS Training Based on the Amended Hazardous Products
Regulations campaign:
A.
Ensure compliance with R.R.O. 1990, Regulation 860, Workplace Hazardous Materials
Information System (WHMIS) in all workplaces where this regulation applies.
More specifically, MLITSD hygienists will determine if retraining on WHMIS will be required
depending on whether the hazardous products in the workplace have labels and safety data
sheets (SDS) that are compliant with the amended Hazardous Products Regulations (HPR).
Q.
What sectors are included?
A.
These campaigns apply to all workplaces in any sector where workers may be exposed to chemical
agents and/or where hazardous products are present.
Q.
I am a small business. Am I included in this campaign?
A.
Yes. The campaigns aim to provide awareness to workers who may be exposed to hazardous
substances, regardless of the size of the business.
Q.
I am an agriculture operation. Are we included?
A.
Ontario Regulation 414/05 for Farming Operations specify where the Occupational Health and
Safety Act and its regulations apply. Although Ontario Regulations 833 and 860 do not apply
to farming, certain aspects of an agriculture operation may be considered part of an industrial
establishment in which case O. Regs 833 and 860 will apply and so will the hygiene campaigns.
An example could be a cannabis operation where parts of the facility will be considered farming
while other parts will be considered industrial. All regulations that apply to industrial establishments,
including Regs 833 and 860, will be enforced in the industrial sections of the facility.
