Clearly, getting too hot can make you sick or worse. This summer, your work crews’ ability to handle extremely hot weather will be dictated largely by acclimatization, ongoing hydration, ample shade, cooling PPE and frequent rest and recovery breaks.

As air temperatures go up, body temperatures also increase along with higher levels of perspiration. If your crews aren’t continually replacing the body fluids they lose through sweating, dehydration can take place.

Occupations that bring people into daily contact with the kind of suffocating heat most of us can escape, such as construction, vehicle repair, firefighting, factory work, present an even higher risk. Add individual worker factors such as age, weight, preexisting medical conditions and medicines that may produce negative side effects under extreme body temperatures, and you’ve got the potential for something pretty serious.

But here’s the cool thing: virtually 100% of heat-related on-the-job illnesses are preventable, from painful cases of heat rash to the far more dangerous heat exhaustion and heat stroke. But the right measure will take some understanding, planning and the commitment of your entire tea.

The best time to replace a car battery is before it dies. A lead acid car battery can last anywhere from 4 to 7 years. Know the warning signs of a weak battery, and how your driving conditions determine your battery's lifespan.
