It’s clear that working in skilled trades during Ontario’s hot summer months brings unique challenges. Whether you’re on a construction site, painting outdoors, or handling heavy equipment, it is essential to be aware of common summer hazards and understand how to prevent them. For workers in union jobs, safety is always a top priority, especially when temperatures rise.
Here’s a breakdown of the most common summer safety hazards, and practical steps you can take to stay safe on the job.
Summer hazards are a real risk for skilled tradespeople.
Summer Hazards to Watch for in the Heat
Summer conditions add a layer of complexity to skilled trades work. The combination of heat, moisture, insects, and equipment wear makes it essential to stay alert. Below are the top summer hazards affecting union jobs and how to avoid them.
1. Heat-Related Illnesses: Heat Exhaustion and Heat Stroke
Why it matters: Long hours in direct sunlight or poorly ventilated spaces increase your risk of heat exhaustion and, more seriously, heat stroke.
What to watch for:
- Dizziness or fainting
- Heavy sweating or no sweating at all
- Headaches
- Confusion or irritability
What to do:
- Take frequent breaks in shaded or air-conditioned areas.
- Hydrate regularly, and avoid caffeine and energy drinks.
- Wear breathable, light-coloured clothing.
- Use the buddy system to check on co-workers.
Quick tip: Employers should follow Ontario’s heat stress guidelines, especially during heat alerts.
2. Slippery Surfaces from Rain or Sweat
Why it matters: Summer storms and sweaty workspaces can create slipping hazards on scaffolding, ladders, and floors.
Prevention strategies:
- Wear slip-resistant footwear.
- Immediately clean up moisture on work surfaces.
- Use anti-slip mats in high-traffic areas.
- Schedule work that requires balance or lifting for early in the day when conditions are cooler.
3. Insect Bites and Stings
Why it matters: Insects like mosquitoes, ticks, and wasps can cause allergic reactions or transmit diseases like Lyme disease.
Prevention strategies:
- Apply insect repellent on exposed skin.
- Wear long sleeves and pants when possible.
- Be cautious near standing water or tall grass.
- Inspect your skin for bites or ticks during breaks and at the end of your shift.
4. Sunburn and Long-Term UV Exposure
Why it matters: Even on cloudy days, UV rays can damage your skin and increase the risk of skin cancer over time.
Sun safety tips:
- Apply SPF 30 or higher sunscreen every two hours.
- Wear wide-brimmed hats and UV-protective clothing.
- Use portable shade canopies when working outdoors.
Good to know: Some union jobs provide access to PPE and gear designed to reduce sun exposure. Make sure to ask your union rep.
5. Equipment Failures Due to Heat
Why it matters: High temperatures can cause machinery to overheat or malfunction, posing risks to the operator and others on site.
Safety practices:
- Inspect tools and machinery at the beginning of each shift.
- Store equipment in shaded or cooler areas.
- Watch for warning signs of overheating (e.g., strange smells, noises, or performance issues).
6. Fatigue and Dehydration
Why it matters: Long workdays, high humidity, and insufficient breaks lead to fatigue and increase the risk of accidents.
Best practices:
- Rotate physically demanding tasks.
- Plan high-intensity work for early morning or late afternoon.
- Drink water every 15–20 minutes.
- Encourage co-workers to speak up when they need a rest.
Heat, fatigue, sun, insects, and faulty equipment are preventable with proactive steps.
