Staying Safe During Hot Weather: A Workplace Guide for Employers
As temperatures rise during the summer months, it's important for employers to consider how hot weather can affect the health, safety and wellbeing of their workforce.
Whether your employees work outdoors, in warehouses, on construction sites or in offices without air conditioning, excessive heat can lead to dehydration, fatigue, reduced concentration and, in severe cases, heat exhaustion or heatstroke.
By taking a few simple precautions, businesses can help create a safer and more comfortable working environment during periods of hot weather.
Why Hot Weather Is a Health & Safety Concern
Working in high temperatures can place additional strain on the body. Employees may become dehydrated more quickly, lose concentration and experience increased fatigue, which can raise the risk of workplace accidents.
Those working outdoors or carrying out physically demanding tasks are particularly vulnerable, but indoor workplaces can also become uncomfortably hot, especially where ventilation is poor.
Employers have a duty to assess workplace risks and take reasonable steps to protect employees from foreseeable hazards, including those caused by hot weather.
Tips for Employers
Encourage Regular Hydration
Ensure employees have easy access to cool drinking water throughout the day and encourage them to drink regularly, even if they don't feel thirsty. Providing refill stations or bottled water can help promote good hydration.
Adjust Working Hours Where Possible
If employees work outdoors, consider scheduling more physically demanding tasks during the cooler parts of the day, such as early morning, and reducing strenuous work during peak afternoon temperatures.
Provide Shade and Rest Breaks
Regular breaks in shaded or cool areas give employees an opportunity to recover and reduce the risk of heat-related illnesses.
Wear Suitable Clothing
Where appropriate, lightweight, breathable clothing can help employees stay cool while still meeting any necessary safety requirements. Outdoor workers should also wear sun protection, including hats and sunscreen where suitable.
Improve Ventilation
For indoor workplaces, open windows where possible, use fans or air conditioning and ensure good airflow throughout the building.
Monitor Employees
Managers should be aware of the signs of heat-related illness and encourage employees to report if they begin feeling unwell.
Recognising Heat Exhaustion
Heat exhaustion can develop when the body becomes too hot and loses excessive amounts of water and salt through sweating.
Common symptoms include:
Heavy sweating
Dizziness or feeling faint
Headache
Muscle cramps
Weakness or tiredness
Nausea
Cool, pale or clammy skin
If someone is showing signs of heat exhaustion:
Move them to a cool place.
Encourage them to drink water or a sports drink.
Loosen unnecessary clothing.
Cool their skin using damp cloths or cool water.
Stay with them until they begin to recover.
If symptoms worsen or do not improve within 30 minutes, seek medical advice.
Heatstroke Is a Medical Emergency
Heatstroke is far more serious and requires immediate medical attention.
Signs include:
Confusion or unusual behaviour
Loss of consciousness
Hot, dry skin (or excessive sweating)
A body temperature above 40°C
Rapid breathing
Call emergency services immediately if heatstroke is suspected.
Carry Out a Seasonal Risk Assessment
Summer conditions can introduce additional workplace hazards. Reviewing your risk assessments during periods of hot weather helps ensure suitable control measures are in place.
Consider factors such as:
Outdoor work activities
PPE requirements
Access to drinking water
Rest facilities
Vulnerable employees
Lone workers
Making small adjustments can significantly reduce risks and improve employee wellbeing.
