Summer is Here

In one of the Safety Talks last month we talked about the allergies that are associated with Spring and the hazards associates with some allergy medications. But now Spring is now behind us and we are headed full-speed into summer.

One of the most significant hazards that summer brings for roofers is heat stress. Although there may not have been very many truly hot and humid days yet this year, now is the time we need to talk about heat stress. Quite honestly, your body is probably not yet ready for the summer heat. Your body gradually adjusts to working in a warm environment through a process known as acclimatization. So until your body has been acclimatized you need to be especially mindful of (1) how to prevent heat stress injuries; (2) how to recognize heat stress; and (3) how to treat heat stress.

Preventative measures

• Wear light-colored, loose-fitting, breathable clothing such as cotton
• Take more breaks in extreme heat and humidity.
• Drink water frequently. Drink enough water that you never become thirsty.

• Avoid drinks with caffeine, alcohol, and large amounts of sugar.

Heat Exhaustion happens when the body is not getting enough salt and water and is a sign the body’s cooling system is not working properly. The victim will sweat heavily, their skin will be cool and moist, their pulse weak, and they will seem tired, confused, clumsy, irritable or upset, they may breathe rapidly–even pant–and their vision may be blurred. The victim may strongly argue that they are okay even with these obvious symptoms. If you suspect heat exhaustion, don’t let the victim talk you out of seeking immediate medical attention. The heat exhaustion will affect their ability to exercise good judgment. Until medical help arrives, try to cool the victim and offer sips of cool water as long as the victim is conscious. Immediate medical attention is required. Heat exhaustion can quickly lead to heat stroke.

Heat Stroke is the deadliest of all heat stress conditions. It occurs when the body’s cooling mechanism has shut down after extreme loss of salt and fluids. The body temperature will rise, the victim’s skin is hot, red, and dry, their pulse fast, and they may complain of headache or dizziness. They will probably be weak, confused, and upset. Later stages of heat stroke cause a loss of consciousness and may lead to convulsions. In the event of heat stroke, seek immediate medical attention. Until help arrives, try to cool the victim and offer sips of cool water if the victim is conscious.

Remember to keep a close eye on your coworkers. You will likely notice signs of heat stress that they do not recognize.
