Report Urges Stronger Heat Protections for B.C. Workers as Temperatures Rise
As another period of intense heat affects the Okanagan, a newly released report is raising concerns about how much heat workers should be expected to endure while performing their jobs.
Researchers from BC Policy Solutions argue that British Columbia’s workplace heat-exposure regulations have failed to keep pace with the growing frequency of extreme temperatures. The report states that the province’s heat-safety rules have not received substantial updates since 2005.
Heat-Related Illness Claims Increased After 2021
The report highlights a significant increase in heat-related workplace illness claims following the 2021 heat dome. Researchers say this rise demonstrates the need for stronger protections before more employees become sick or injured.
Outdoor workers, including roofers, regularly experience these risks. Simranpreet Singh, a senior roofer with Pinnacle Roofing, explained that employees can quickly become exhausted while working on rooftops.
Crews attempt to remain hydrated by drinking water, sports drinks and other beverages containing electrolytes.
Roofers Experience Dizziness and Mental Fog
Victor Neilson, a site supervisor with the roofing company, said dizziness is one of the most common warning signs of heat exhaustion.
Workers may also experience brain fog, weakness and a general feeling that something is wrong. According to Neilson, almost every member of his crew has already needed at least one day away from work this year after being exposed to extreme heat.
Report Recommends Automatic Heat-Safety Measures
Researchers are recommending clear temperature thresholds that would automatically require employers to introduce additional workplace protections.
These measures could include:
- Reliable access to cool drinking water
- Shaded recovery areas
- Paid rest breaks
- Heat-illness prevention training
- Acclimatization plans for new and returning employees
- Better access to washrooms
- Stronger enforcement of workplace regulations
The report also calls for greater protection for vulnerable employees. Broader proposals include hazard pay during periods of extreme heat and improved housing conditions for migrant workers.
WorkSafeBC Says Temperature Is Not the Only Factor
WorkSafeBC says worker safety cannot be determined by setting a single maximum temperature. Air circulation, ventilation, humidity and radiant heat can all influence the level of danger employees face.
Roofing crews often experience temperatures much higher than those recorded at ground level. Singh estimated that conditions on a roof can feel approximately 10 degrees hotter than the surrounding temperature, especially when there is little or no wind.
Roofing Crews Adapt Their Work Schedules
Until stronger regulations are introduced, roofing crews are relying on practical measures to reduce heat exposure.
Workers begin as early as possible, take regular breaks in shaded areas and place wet towels around their necks to cool their bodies. Even a light breeze can make rooftop conditions more manageable.
The report warns that British Columbia’s existing workplace heat regulations may no longer provide sufficient protection during increasingly frequent extreme-weather events.
Until updated rules are introduced, outdoor workers must remain alert to early symptoms such as dizziness, exhaustion and mental confusion. Recognizing these warning signs and taking immediate breaks could prevent serious heat-related illnesses.
