Blog: How to Keep Cool While Working in Hot Weather
Working in hot weather can be challenging and uncomfortable. Imagine being forced to stay at home for the whole day with poor ventilation and no cooling equipment on a hot summer day. Isn't it a nightmare? If one has to work in a workplace similar to this one, it can only be worse. In addition to longer sunlight and cosier conditions in spring and summer, it indicates an increase in temperature, to which we should all pay close attention, particularly in the workplace. High temperatures or stuffiness at work can cause serious consequences if they are not attended to carefully. It is important to take the necessary precautions to keep cool and prevent heat-related illnesses.
Consequences Of Working In The Heat
As the sun stops hiding and the weather is getting better, it's a sign of something that we have been longing for - warm weather! However, the sun can be deterring on a summer afternoon. Apart from skin problems arising from exposure to sunlight, there are more concerning problems with working outdoors at high temperatures. Heat stress is more likely to happen when the air is humid and still and there is prolonged exposure to direct heat radiation. It increases exhaustion and could put additional pressure on the cardiovascular system, resulting in symptoms like an inability to concentrate, dizziness, a rapid pulse and clammy skin. If it gets worse, heat stroke may develop and could result in hot, dry skin and consequently death.
On the other hand, rising temperatures make it more likely that people will become fatigued, which raises the risk of accidents when working indoors as well. As the temperature goes up, people sweat even when they don't move. This makes them more stressed, less able to focus and more likely to make mistakes. In terms of manual work, high heat might contribute to dehydration and potential heat stress. Working in excessive heat, whether indoors or outdoors, can be uncomfortable and undoubtedly increase the risk of accidents and injuries. Not only does it have a huge impact on productivity, but it also jeopardises one's physical health.
What The Law Says
According to the law, employers are legally obligated to provide a safe and healthy work environment. The Workplace (Health, Safety and Welfare) Regulations state that employers must provide a reasonable indoor temperature for their workplace, taking into account the nature of the work and environmental conditions. The Approved Code of Practice on the regulation recommends a minimum indoor working temperature of 16°C, or 13°C if the work involves demanding physical activity.
The Construction (Design and Management) Regulations require reasonable indoor temperatures on construction sites, and outdoor sites must supply protection against adverse weather. Furthermore, the temperature of the site's rest areas must be regulated.
Our Solutions
There are a few different approaches to coping with the heat in the workplace. One affordable way to reduce direct heat and glare is to shade windows and keep blinds, shutters and curtains closed. Besides, it's worth considering insulation for buildings, as it can help keep heat out in the summer and retain heat in the winter. To help combat high temperatures, it's also helpful to offer free chilly drinks or a stable supply of water at work to keep employees hydrated and allow for extra breaks, preferably in cooler areas, if the work involves rigorous physical demands. Another measure that can be taken is relaxing formal dress codes or removing the requirement to wear heavy uniforms where possible.
On top of those, a once-and-for-all measure is to make sure that your workplace is equipped with good cooling effects and ventilation. To permanently address the issue, it is necessary to install air conditioning units in offices and site rest facilities. By installing air conditioning systems or providing cooling fans to ensure a comfortable working environment, especially during hot weather conditions, you can accomplish good ventilation by having a steady flow of refrigerated, filtered air. At National Heater Shops, we stock an extensive range of high-performance and cost-effective cooling equipment. Below are a few ideas for cooling solutions in the workplace.
1. Portable Air Conditioner
Portable air conditioning units are a convenient and easy way to cool any room without the need for complex or expensive installation. They can be easily transported from one room to another, making them ideal for business applications like shops, offices, workshops and even site rest facilities. By using these 'plug and play' air conditioning units, you can quickly create a comfortable work environment. Moreover, some models even have air purifying capabilities to improve the quality of the air you breathe. Available in a variety of sizes and with features such as thermostats, remote controls and WiFi connectivity, portable air conditioners are an excellent option for anyone looking for a hassle-free solution to workplace heat.

3. Evaporative Air Coolers
Evaporative coolers, also known as swamp coolers, supply cool, humid air and add moisture to the air in hot and dry areas to create a comfortable environment. The extra water absorbs heat from the surroundings and evaporates, which results in a reduction in temperature. The cooler air is then circulated via an internal fan. These machines are perfect for use in well-ventilated indoor and outdoor spaces such as cafes, restaurants and bar terraces, workshops, warehouses, events and site rest areas. Evaporative coolers are simple yet effective and affordable to run, making them an ideal choice for keeping staff and workers cool during hot weather and summer days.
