Safety Focus of the Month: Heat Stress & Hydration

Warmer weather is here — and for our crews working in the field, that means heat stress is a real hazard. As temperatures climb, your body works harder to stay cool. Heat stress can affect anyone, reducing focus, slowing reaction time, and increasing the risk of accidents. The earlier you recognize and respond to symptoms, the safer you’ll be.

Know the Warning Signs of Dehydration & Heat-Related Illness

Early Signs — Act Immediately:

• Thirst, dry mouth

• Headache

• Fatigue or weakness

• Muscle cramps

  
  

Serious Signs — Medical Emergency:

• Confusion or disorientation

• Fainting

• Hot, dry skin (no sweating)

• Rapid pulse or breathing

  
  

If someone shows serious symptoms:

• Call for help immediately

• Move them to a cool or shaded area

• Cool the body (wet cloths, fans, ice packs if available)

Hydration Basics

• Don’t wait until you’re thirsty — by then, you’re already dehydrated.

• Drink small amounts frequently (about 1 cup every 15–20 minutes in hot conditions).

• Increase intake during heavy work, high humidity, or direct sun exposure.

• Balance water with electrolytes during prolonged sweating.

• Avoid excess caffeine, sugary beverages, and alcohol — especially before or after shifts.

Prevention Strategies:

Acclimatization:

• New or returning workers should gradually increase heat exposure over 5–7 days.

• The body needs time to adapt — don’t rush it.

  
  

Work/Rest Cycles:

• Schedule the heaviest tasks during cooler parts of the day.

• Take regular breaks in shaded or air-conditioned areas.

  
  

Clothing Choices:

• Wear light-colored, loose-fitting, breathable fabrics.

• Use cooling towels or moisture-wicking gear when possible.

  
  

Buddy System:

• Look out for each other — heat illness can impair judgment before a person even realizes they’re affected.

• Speak up if a coworker seems off.
