Working Safely in the Heat: Essential Tips for Operatives

Working in hot conditions increases the risk of dehydration, heat exhaustion, sun-related illnesses, and fatigue. For operatives, understanding how to stay safe and healthy whenever working in the heat is vital to maintaining wellbeing and productivity.

Why Heat Safety Matters for Operatives

Heat stress can quickly affect both physical and mental performance. Early symptoms include dizziness, confusion, excessive sweating, and fatigue. Recognising these warning signs and responding promptly is essential to prevent serious health issues.

Hydration: The Key to Staying Safe in the Heat

Since water makes up around 75% of the human body, maintaining hydration is critical when working in heat. Operatives should:

  • Drink at least 2 litres of water every day and increase this amount depending on activity levels and temperature.

  • Avoid drinks that dehydrate, such as alcohol, coffee, tea, and caffeinated soft drinks.

  • Carry a reusable water bottle at all times, whether travelling or on site.

  • Use urine colour as a guide: dark, strong-smelling urine means more fluids are needed.

  • To help keep hydrated, set regular reminders on phones or computers to drink water throughout the day.

Protecting Skin from UV Damage

Skin damage is caused by UV rays, not temperature. This means skin can be harmed even when it feels cool or when the sky is cloudy. Key points include:

  • UV exposure causes permanent skin damage regardless of skin type or colour.

  • Fake tan lotions with SPF cannot be relied on for continuous protection.

  • Un-tinted glass reduces sunlight but does not completely block UV rays, so prolonged exposure near windows can still cause damage.

  • Always apply broad-spectrum sunscreen with an appropriate SPF and reapply regularly.

  • Wear protective clothing, hats, and sunglasses to reduce UV exposure.

Recognising and Responding to Heat-Related Fatigue

Being aware of heat-related fatigue is crucial. Watch for symptoms such as:

  • Dizziness or light-headedness

  • Confusion or difficulty concentrating

  • Excessive sweating or clammy skin

  • Nausea or headaches

If these symptoms occur:

  • Move to a cooler or shaded area immediately

  • Drink water or electrolyte fluids

  • Rest until symptoms improve

  • Seek medical help if symptoms worsen

Practical Tips for Staying Safe Whenever Working in Heat

  • Stay hydrated by drinking water regularly.

  • Wear light, breathable clothing that covers the skin.

  • Use sunscreen and sun protection consistently.

  • Take breaks in shaded or cool areas when possible.

  • Keep a reusable water bottle with you at all times.

  • Educate all team members on heat safety awareness and response.
