You have to wonder why weather forecasters need to state the obvious. They remind us to stay out of the sun, wear light clothing, drink plenty of fluids, and take frequent breaks if we "must be outdoors in this heat." When hot, humid 'air you can wear' hits you in the face the minute you step outside, it's a no-brainer; run back inside, sit in front of a fan and drink ice water. But you have no choice if your job requires you to be outdoors when it's 100 degrees. You become an expert on staying comfortable and safe because your life depends on it. Our forecaster friends warn us to pay attention to our health while concentrating on our outdoor work.
Not that it gets any more comfortable with experience. Our UCEMC linemen ride in buckets to get up-up-up to where the heat is unbearable. They wear fire-retardant (FR) protective, long-sleeved clothing, thick rubber gloves, sleeve coverings, and unventilated hard hats. This required personal protective equipment (PPE) causes them to drip with sweat as they work with electricity.
