Heatwave Safety at Work – Protecting Ourselves and Each Other

The UK is currently experiencing exceptionally high temperatures, with parts of the country subject to rare Heat-Health Alerts and forecasts predicting temperatures well above seasonal averages. The UK Health Security Agency (UKHSA) has issued Red and Amber Heat-Health Alerts across large parts of England, highlighting the potential impact of extreme heat on health, wellbeing, and business operations.

While many people enjoy warmer weather, prolonged exposure to high temperatures can create serious health and safety risks in the workplace. Heat stress can affect concentration, increase fatigue, and raise the likelihood of accidents and illness.

Why Heat Safety Matters

Working in hot conditions can lead to:

• Dehydration
• Heat exhaustion
• Heatstroke (a medical emergency)
• Reduced concentration and decision-making
• Increased risk of workplace accidents
• Fatigue and reduced productivity

Outdoor workers, those undertaking physically demanding tasks, and employees working in poorly ventilated environments may be particularly at risk.

Practical Steps to Stay Safe

Stay Hydrated

• Drink water regularly throughout the day.
• Do not wait until you feel thirsty.
• Avoid excessive caffeine and energy drinks, which can contribute to dehydration.

Take Regular Breaks

• Use rest areas where possible.
• Schedule physically demanding tasks during cooler parts of the day.
• Take additional breaks if you begin to feel overheated.

Dress Appropriately

• Wear lightweight, breathable clothing where work activities permit.
• Use suitable sun protection when working outdoors, including hats and sunscreen.

Reduce Exposure to Direct Sunlight

• Seek shade whenever possible.
• Avoid prolonged periods in direct sunlight, particularly between 11am and 3pm when UV levels are highest.

Keep Work Areas Cool

• Open windows and doors where safe to do so.
• Use fans or other cooling equipment where available.
• Keep blinds or curtains closed on sun-facing windows.

Recognising the Signs of Heat-Related Illness

Heat Exhaustion

Symptoms may include:

• Dizziness
• Headache
• Excessive sweating
• Muscle cramps
• Nausea
• Weakness or tiredness

If someone develops these symptoms:

1. Move them to a cooler area.
2. Encourage them to drink water.
3. Loosen unnecessary clothing.
4. Monitor their condition and seek medical advice if symptoms persist.

Heatstroke: Call Emergency Services Immediately

Heatstroke is a medical emergency. Signs include:

• Confusion or altered behaviour
• Loss of consciousness
• Hot, dry skin
• Seizures
• Very high body temperature

Call 999 immediately if heatstroke is suspected.

Managers and Supervisors

Managers should continue to assess risks associated with hot weather and consider:

• Adjusting working hours where practical.
• Increasing access to drinking water.
• Providing additional rest breaks.
• Monitoring vulnerable employees.
• Reviewing outdoor work activities and manual handling tasks during peak temperatures.

Looking Out for Each Other

Heat affects everyone differently. Some colleagues may be more vulnerable due to age, pregnancy, underlying health conditions, or medication.

Please check in with your colleagues, particularly those working alone or outdoors, and speak to your manager if you have concerns about working conditions during the heatwave.

Remember!

The current heatwave serves as an important reminder that hot weather is a workplace health and safety issue. By taking sensible precautions, staying hydrated, and looking out for one another, we can help ensure everyone remains safe and well throughout this period of extreme temperatures.

Stay cool, stay hydrated, and stay safe.
