Alberta Workplace Temperature Rights: OHS Act & Refusal‑to‑Work Process

Legal Framework in Alberta

Alberta has no legislated maximum/minimum temperature. However, the Occupational Health and Safety Act requires employers to provide a workplace free from recognized hazards—including thermal extremes.

When Temperature Becomes a Hazard

• Heat: core temp rise, heat exhaustion/stroke risk (outdoor, foundries, bakeries)
• Cold: hypothermia, frostbite, reduced dexterity (freezers, winter construction)

Worker Rights & Process

1. Report concern to supervisor/employer.
2. If unresolved, exercise right to refuse dangerous work (OHS Act, Section 31).
3. File complaint with Alberta OHS Contact Centre (1‑866‑415‑8690).
4. OHS investigates; may issue compliance orders.

Personal Protective Measures

• Hydration, rest breaks, shade/cooling stations (heat)
• Layered insulated clothing, heated shelters, warm fluids (cold)
• Recognize early symptoms: dizziness, confusion, shivering cessation → seek help immediately
