Working at height is an inherently risky activity, and when combined with extreme weather conditions like a heatwave, it can quickly become dangerous. As temperatures soar, workers who regularly perform tasks at height face many additional challenges – so can you really work safely at height during a heatwave?
In this blog, we’ll explore the risks of working at height during a heatwave, what the law says about the issue, and what safety measures you can take to protect your workers and ensure safe working conditions.
What are the Risks of Working at Height in a Heatwave?
Working at height during a heatwave presents significant risks. The most immediate concern is the physical toll extreme heat can take on workers. Dehydration, heat exhaustion, and heatstroke are all possible outcomes, especially when workers are exerting themselves on scaffolding, ladders, or rooftops.
The risks are compounded when workers lose focus or become fatigued due to the heat. This can lead to poor decision-making and slower reactions, both of which can increase the likelihood of accidents and falls. In fact, heat-induced fatigue and dizziness can result in a worker losing their grip or stability, which poses a serious fall hazard.
That’s why completing our working at height online course here at NATAS is vital to properly assess these risks and make sure workers are trained to manage them effectively in extreme conditions.

What Does the Law Say About Working in Extreme Heat?
The Health and Safety Executive (HSE) sets clear guidelines for employers regarding working in extreme temperatures. These guidelines focus on the fact that employers must assess and control the risks associated with working in hot environments. Here’s a summary of what you need to know:
HSE guidelines:
The HSE recognises that extreme heat can impair workers’ ability to perform tasks safely, especially when working at height. It’s vital to monitor works for signs of heat-related illnesses and to ensure regular breaks in cooler environments.
Employer’s duty of care:
Employers must take action to ensure the safety of their workers. This could include adjusting work schedules, limiting the duration of tasks, or halting work entirely if the risks are too high.

Safety Measures to Take When Working at Height in a Heatwave:
Key safety measures to follow during a heatwave include:
Wear appropriate clothing and PPE:
Make sure workers are wearing lightweight, breathable clothing and safety gear to help regulate body temperature.
Stay hydrated:
Workers should have access to plenty of water throughout the day to stay hydrated and avoid heat-related illness.
Regular breaks:
Schedule frequent breaks in shaded or cool areas to give workers a chance to recover from the heat.
Monitor workers for heat stress:
Employers should keep an eye on workers for signs of heat exhaustion, like dizziness, heavy sweating, or confusion.
Avoid working during peak heat:
If possible, schedule tasks during cooler times of the day, like early morning or late afternoon, to minimise heat exposure.

How Can a Working at Height Course Help?
Training plays an important role in making sure workers understand the risks and know how to protect themselves when working at height, especially in extreme conditions like a heatwave. Here’s how our working at height course can help:
Risk assessment skills:
Workers will learn how to identify the specific risks of working at height during extreme weather, including heat-related hazards.
Control measures:
The course will teach workers the necessary control measures to implement when working in hot conditions, such as how to adjust work practices and use the right equipment.
Emergency procedures:
Our working at height online course delivers vital information on the procedures to follow in case of heat-related illnesses, ensuring workers know what to do if someone shows symptoms of heatstroke or exhaustion.
Understanding legal responsibilities:
The course ensures workers and employers are aware of their legal duties, including compliance with HSE regulations regarding working in extreme temperatures.
