TIPS FOR WORKING IN SUMMER AND EXTREME HEAT

Southern Alberta summers can produce periods of extreme heat and dry conditions, with the potential for severe thunderstorms. It is important to be aware of the weather in advance to properly mitigate the effects of extreme heat and plan for the potential severe weather.

Signs of heat stress 

Starting symptoms

• Irritability 
• Headaches and confusion 
• Fainting, dizziness and fatigue 
• Muscle cramps and sweating 
• Dehydration 
• Heat rash

Worsening symptoms

• Sweating may stop
• Severe muscle cramps
• Changes to pulse rate
• Trouble breathing
• Hot and dry skin
• Exhaustion

Planning ahead

• Checking ahead of the weather can allow for re-organizing work tasks to cooler days or time of day
• Conduct or revise your hazard assessment to include heat hazards and controls, e.g. cooling station
• Revising the work plan for the tasks to factor in appropriate breaks from the heat
• Consider clothing choice — hats, breathable materials like cotton, avoid dark coloured clothes

Prevention and mitigation

Acclimatization to the temperature generally takes six to seven days but some individuals may need longer. A decrease in heat tolerance can occur even after a few days. It is advisable to not assume a full workload under very hot conditions on the first day of your return to work.

Hydration is very important during high temperatures as you will lose water through sweating. It is recommended to drink one cup of water every 15 to 20 minutes while working in high temperatures.

Cooling areas are another way to help lessen the effects of the heat. When possible, find rest areas in the shade when outdoors or have a cool location to go for breaks, such as an air conditioned room or building. Taking breaks out of the heat in these locations can help minimize the effects of the heat.

Severe weather

Summers in southern Alberta are known to create severe weather such as strong winds, thunderstorms, hail, lighting and potentially tornados. It is important to stay current with the weather and watch for updates and notices of possible severe weather.

• Get indoors when thunder roars or hail starts to fall
• During hailstorms, avoid windows, glass doors and skylights
• In high winds take care of debris, and secure loose objects
