Beat the Heat: Preventing Heat Exhaustion on the Jobsite

When the temperatures rise, so do the risks — and we’re not just talking about sunburns and awkward pit stains. For those working in the trades, especially outdoors or in hot indoor environments, heat exhaustion is a serious health hazard that can sneak up faster than you can say, “where’s my water bottle?”

What Is Heat Exhaustion?

Heat exhaustion happens when your body overheats and can’t cool itself down fast enough. It’s often caused by prolonged exposure to high temperatures, especially when combined with physical activity and inadequate hydration. Symptoms include:

• Dizziness or fainting
  
• Heavy sweating
  
• Weakness or fatigue
  
• Nausea or vomiting
  
• Headaches
  
• Muscle cramps
  

Ignore these signs, and you risk progressing to heat stroke — a life-threatening condition that requires immediate medical attention.

PPE: Friend or Foe?

Here’s the catch: while PPE protects you from jobsite hazards, it can also trap heat if you’re not wearing the right kind. That’s why selecting hot-weather appropriate PPE is critical.

Look for PPE that’s:

• Breathable and moisture-wicking – Fabrics like lightweight FR blends or vented hi-vis gear allow airflow while keeping you protected.
  
• Light-colored and UV-resistant – These reduce heat absorption and provide sun protection.
  
• Designed for summer use – Yes, that’s a thing! Think vented hard hats, mesh safety vests, and cooling accessories.
  

At Brasco Safety, we carry a range of PPE built for Canadian summers — because the only thing more brutal than July humidity is doing your job in the wrong gear.

Hydration: The Real MVP

Even with the best PPE, your body needs water to function properly in the heat. Here’s how to keep hydration from becoming an afterthought:

• Drink water regularly – Don’t wait until you’re thirsty. That’s your body already waving a white flag.
  
• Avoid energy drinks and too much caffeine – Sorry, but they can make dehydration worse.
  
• Encourage a hydration culture – Supervisors should build in water breaks and ensure access to clean, cool drinking water.
  

Safety Isn’t Seasonal

Working through the heat is tough — but with the right gear and the right habits, it doesn’t have to be dangerous. At Brasco Safety, we believe staying safe doesn’t mean suffering through summer.
