Heat & Cold Stress Prevention

A core interactive course on heat and cold stress: 11 scenarios recognizing early heat exhaustion, heat stroke, and cold injury in real conditions, validating 7 competencies. It gets crews acting at the warning stage instead of the emergency.

Manitoba workers face both extremes — hot, humid summers and some of the coldest winters in the country — and both can make you ill or kill you. This course teaches every worker to recognize the signs of heat illness (heat rash and cramps, heat exhaustion, and life-threatening heat stroke) and cold injury (cold stress, frostnip and frostbite, and life-threatening hypothermia) and how they progress; to apply the controls that prevent them (for heat: water, rest, shade, acclimatization, and work/rest cycles; for cold: layering, staying dry, warm-up breaks, wind protection, and protecting the extremities); to respond correctly to a thermal emergency, including when to call EMS; to use the hierarchy of controls and environmental monitoring (the Humidex for heat and the Wind Chill index for cold); and to use the buddy system and self-monitoring. The online theory establishes the Trained state; the employer records the site confirmations (heat response, cold dress, site controls, and a risk review) as the Observed state, signed off as Competent.

Equip every worker exposed to heat or cold to recognize the early signs, apply the controls (water-rest-shade and acclimatization for heat; layering, staying dry, and warm-up breaks for cold), respond to an emergency, and monitor the conditions — so heat illness and cold injury are prevented.

What you will learn

Course outline

  1. Why Temperature Is a Hazard — How heat and cold harm the body, the signs of each, and who is most at risk.
  2. Heat Stress — What drives heat illness and the controls that prevent it — water, rest, shade, acclimatization, and pacing.
  3. Cold Stress — What drives cold injury in a Manitoba winter and the controls — layering, staying dry, warm-up breaks, and wind protection.
  4. Controls, Monitoring & First Response — The hierarchy of controls for thermal stress, monitoring the Humidex/Wind Chill, and emergency first response.
  5. Reporting, the Program & Your Site — Reporting thermal symptoms and hazards, the workplace program, and the site-specific layer you must know.

Laws and standards covered

Certificate and renewal

Passing the final test issues a QR-verified certificate, valid for one year. Review training at least annually and seasonally (before summer heat and before winter cold), and whenever work, conditions, or PPE change. No exact mandatory theory-hour minimum is set in Manitoba law — industry/provider standard applies.
