Record-breaking temperatures put workers at risk of heat stress

With temperatures forecast to reach 36 degrees in Penticton, Summerland, Osoyoos and the surrounding region this week, WorkSafeBC is alerting employers and outdoor workers of the risk of developing symptoms of heat stress this summer.

If left untreated, heat stress can lead to injuries from heat exhaustion and heat stroke.

In 2016, there were 16 accepted claims for work-related injuries caused by heat exhaustion and heat stroke. The occupations with the highest number of heat stress-related claims last year included: truck and bus drivers, lifeguards, recreation sport and fitness leaders and motion-picture production assistants. In the OkanaganSimilkameen region, there were three accepted claims for heat stress-related injuries from 2007–16.

“Outdoor workers face many risks when the weather is hot,” said WorkSafeBC prevention field services director Dan Strand. “By law, employers are required to know if their workers are at risk by performing a heat-stress assessment and implementing a mitigation plan when necessary.”

Heat stress occurs when your internal temperature increases faster than the body can cool itself. Symptoms of heat exhaustion include excess sweating, dizziness, fainting and muscle cramps. Symptoms of heat stroke include cessation of sweating, an increased breathing rate, confusion, seizures and even cardiac arrest.

PREVENTION OF HEAT STRESS FOR EMPLOYERS: • Monitor heat conditions and require workers not to work alone

• Ensure there is adequate first-aid coverage and emergency procedures are in place

• Change work practices and policies to limit the risk

• Make physical modifications to facilities, equipment, processes to reduce exposure

• Determine appropriate work-rest cycles; when a worker feels ill it may be too late

• Rotate work activities or use additional workers to reduce exposure

• Establish cooling areas with shade and water

PREVENTION OF HEAT STRESS FOR WORKERS: • Drink plenty of water (one glass every 20 minutes)

• Wear light-coloured, loose-fitting clothing made of breathable fabric such as cotton

• Take rest breaks in a cool, well-ventilated area

• Do the hardest physical work during the coolest parts of the day, before 11 a.m. and after 3 p.m.

• Know your personal risk factors such as medications and any pre-existing conditions

• Check the signs and symptoms for yourself and co-workers
