Bill 222

Worker under heat stress

Why it is important?

Ontario’s Bill 222, referred to as the Heat Stress Act, is set to amend the OHSA. Currently, the bill is before the Ontario Legislature where it has received first reading and it will come into effect 12 months after it receives Royal Assent.

Heat Risk Assessment

This isn't a one-time event. Employers must conduct regular assessments to identify jobs, tasks, and work environments where workers are exposed to hazardous levels of heat. It should consider factors like:

• Temperature
• Work Intensity
• Personal Factors
• Acclimatization
• Protective Equipment

Implementing a Heat Stress Policy

A comprehensive document outlining the employer's approach to heat stress prevention and management.
• Procedures for identifying and assessing heat risks.
• Hierarchy of controls.
• Procedures for monitoring workers' health and well-being.
• Emergency response plan.
• Training requirements.
• Communication protocols.
• Record-keeping.

High sodium intake doesn't just affect long-term health—it can impact daily performance on your job sites. Excessive sodium consumption leads to:

  • Increased bloating and water retention, making workers feel sluggish and uncomfortable
  • Dehydration, as the body struggles to maintain proper fluid balance
  • Reduced mental clarity, affecting decision-making in high-risk environments

Mandatory Worker Training

All workers must receive training on heat stress. Supervisors require additional training on monitoring heat conditions, recognizing signs of heat illness in workers, and implementing emergency procedures.
