Final answer:
Ministers can consider both workplace size and accident history when it comes to JHSC.
Step-by-step explanation:
When it comes to the Joint Health and Safety Committee (JHSC) under the Occupational Health and Safety Act (OHSA), Ministers can consider both workplace size and accident history. The JHSC is responsible for promoting and maintaining health and safety in the workplace, and it consists of both worker and management representatives. Considering workplace size helps determine the necessary resources and policies needed to ensure a safe and healthy environment, while accident history provides insights into the specific hazards and risks that should be addressed.
