When summer is here, beware of its energy-sapping heat. For construction workers in particular, heat is not only uncomfortable, but also dangerous.
Working during the summer months means many workers are at risk of heat-related illness – especially when exposed to direct sunlight and high temperatures, involved in heavy physical labour, or required to wear heavy protective clothing.
Learn about the dangers of heat stress, what it means for workers at risk, and how to combat the dangers by using the correct protective safety solutions.
Heat stress: risk factors & occupational hazards
Heat stress is a physical condition in which the body cannot get rid of excess heat. It causes the body’s core temperature to go up, increasing heart rate and making it difficult for a person to focus on a task. In severe instances, heat stress causes irritability, sickness, fainting, and even death.
In addition to health and safety concerns, heat- related illnesses lead to poor performance and lost productivity. According to NIOSH (US National Institute for Occupational Safety and Health), for every 1,000 workers, 2 are at risk for heat stress. That number goes up, too, depending on occupation. For example, those working in construction mining, and manufacturing are at even greater risk for occupational exposure to heat stress due to the combination of a hot environment and high physical demand.
But what are the symptoms of heat stress?
Heat stress comes in various forms:
Heat Stroke is the most serious heat-related illness. It occurs when the body becomes unable to control its temperature: the body’s temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down.
When heat stroke occurs, the body temperature can rise to 41°C or higher within 10 to 15 minutes. Heat stroke can cause death or permanent disability if emergency treatment is not given.
Symptoms of heat stroke may include:
Heat Exhaustion is often a precursor to heat stroke. It is often accompanied by elevated core body temperatures around 38°C–39°C.
Symptoms of heat exhaustion may include:
