Health and security

Heat exhaustion for workers is a common risk when temperatures are too high. Symptoms include dizziness, headaches, shaking and thirst. An even more serious medical problem is heat stroke, which occurs when the body’s core temperature rises above 40.6 °C (105 °F).

This condition can lead to long-term organ damage and possibly death. Long-lasting heat can also cause a range of chronic health problems. Constant exposure to heat can be hard on the heart and kidneys, disrupt sleep and challenge our mental health.

During the work day, what can be done to help adapt to the heat? It is important for employers to prevent risks, meaning shifting working hours, reinforcing air conditioning, providing refreshment facilities or even increasing the number of breaks.

Workplace conditions are changing

In recent weeks, several countries have had to implement emergency protocols to deal with the high temperatures. Iran, with temperatures going up to 50 °C, declared two public holidays for public services and banks on Aug. 2 and 3. Back in June, the government had modified the working hours of public employees to allow them to start their day earlier, and in the process save energy.

In France, the “Code du Travail” (workplace code and ethic), does not determine a maximum workplace temperature, but it does require employers to make sure their workers are able to do their job under safe conditions, which applies to extreme heat.

In Spain and the United States, the media reported several deaths of people working outdoors despite the heatwave. Spanish media El Diaro reports that businesses have been fined up to 330,000 euros for risking their employees lives and health by failing to comply with safety regulations in the summer heat.

In Germany, Johannes Niessen, head of the Association of German Public Health Service Doctors, offered to extend the lunch break during the summer to allow for a “siesta,” reports German daily Süddeutsche Zeitung. The origins of this practice lie in the Spanish “siesta,” dating back to the time when rural workers took breaks during the hottest part of the day.

Sustainable solutions for the workplace

Apart from the obvious solutions like frequent water breaks and flexible working hours, there are other practices that can be implemented to help their workers deal with severe heat.

Employers should raise awareness about heat’s effect on health.

Cities could plant more trees in urban areas, which would prevent the accumulation of heat in concrete and significantly cool down buildings.

Employers should also raise awareness about heat’s effect on health, emphasizing the importance of hydration and train workers on detecting early symptoms of heatstroke.

For those where the job allows it, working from home is also an option to stay cool as employees can dress informally. But it should also be an option to come into the office when it is equipped with air conditioning.

The real problem

While nations reform laws or implement new regulations, we must not forget that this is only a symptom of climate change. According to a report released in May by the World Meteorological Organization (WMO), global temperatures are likely to soar to record levels in the next five years.

Summer often reveals the impact of climate change with extreme weather, floods, and fires around the globe. Seeing our daily lives impacted by high temperatures and being forced to change the way we operate when facing the heat, is a reminder of what is happening to our planet.
