5 Ways to Stay Cool On-Site this Summer

As Summer finally begins to heat up, working on construction sites can become challenging. The increase in temperature can affect not only your comfort but also your safety and productivity on the job site. At THX, we understand the importance of staying cool and hydrated while on the job. That’s why we’ve put together 5 practical ways to beat the heat and stay cool on-site this summer.


Staying hydrated is essential when working in hot conditions. Make it a habit to drink plenty of water throughout the day, even before you feel thirsty. Dehydration can impact your concentration and physical performance, leading to potential mistakes and potential injury.

Aim to rehydrate every 15-20 minutes during intense physical activity and consider incorporating electrolyte-replenishing drinks to maintain your body’s balance of salts and minerals that are lost through sweat.

Tip: Set reminders on your phone or watch to take regular water breaks, especially during the busiest parts of the day.


Choosing the right clothing can significantly impact your comfort levels on-site. Opting for lightweight, breathable fabrics such as cotton or moisture-wicking materials help to evaporate sweat more efficiently, keeping you cool and dry.

Light-coloured clothing is also beneficial as it reflects the sunlight, reducing heat absorption. A bandana or neck gaiter can also help absorb sweat and keep you cool.

Tip: Invest in a good pair of sunglasses with UV protection to shield your eyes from harmful rays, reducing the risk of headaches and eye strain. It is important to note that individual construction companies may have specific policies regarding the type of sunglasses or protective eye-wear that workers can use. Make sure to check with your employer that your sunglasses comply with company policies.

3. take regular breaks in the shade

Even if you are dressed appropriately, working in direct sunlight for extended periods can be dangerous and exhausting. Ensure you take regular breaks in shaded or cool areas to rest and cool down. These breaks are not just luxury; they are a necessity to prevent heat-related illnesses.

If you lack natural shade in certain areas of your site, consider setting up temporary shelters such as pop-up canopies or portal tents. These can provide you and your workers with much- needed relief from the sun. 

Tip: Plan your breaks strategically, scheduling longer breaks during the peak heat hours of the day. If you can rotate team members for certain projects, make sure rotation gives everyone a break from the sun.


One of the most effective ways to stay cool on-site is by improving air circulation. Industrial fans and air conditioning units are perfect for keeping your site and workers cool and comfortable. Industrial fans can help create a breeze that evaporates sweat, while portable air conditioning units can cool down enclosed spaces such as site offices or break areas.

Hiring in cooling equipment is a cost-effective method to stay cool on-site, as buying industrial-grade fans can be a significant investment for only a few months in the summer. These are also flexible and scalable to your projects and current requirements.

Tip: Position fans and air conditioning units strategically to maximise airflow and cooling efficiency. Use barriers or curtains to section off areas for better temperature control.

At  THX, we offer a range of industrial fans and portable air conditioning units for hire with next day delivery, two hour time slots, and a 98.9% hire fleet reliability rate.

5. stay informed

Educating yourself and your team about the signs of heat-related illnesses is crucial. Heat exhaustion and heat stroke are series conditions that can escalate quickly if not addressed promptly. Knowing the symptoms and how to respond can prevents severe health issues.

Symptoms include: heavy sweating, weakness, dizziness, nausea, and headache.
If untreated, it can progress to heat stroke, characterised by a high body temperature, confusion, rapid pulse, and loss of consciousness.

Keeping your eye on the forecast and managing work schedules to avoid peak heat hours, such as starting earlier in the morning or scheduling more intensive tasks for cooler parts of the day, can significantly reduce the risk of heat-related illnesses.

The Healthy and Safety Executive (HSE) is the UK’s national regulator for workplace health and safety. Their website provides guidance and resources on a range of topics, including sun safety and PPE.

Tip: Conduct regular safety meetings focused on heat safety and ensure everyone on site is aware of the protocols.


Staying cool on site during the summer is not just about comfort; it’s a vital part of ensuring the safety and well-being of your team. By following these tips and taking proactive measures, you can maintain a productive and safe working environment even in the hottest conditions.
