Excessive Heat Warning: Drivers Urged to Know the Signs of Dehydration, Heat Exhaustion and Heat Stroke

ST. LOUIS, July 21, 2011 – As the summer heat sizzles across the St. Louis area and excessive heat warnings are extended, more and more workers are spending several hours per day in extreme temperatures while performing their jobs. Workers who drive trucks and other service vehicles are particularly vulnerable to the symptoms of dehydration, heat exhaustion and heat stroke. Many trucks, including delivery trucks, construction vehicles and even Waste Management garbage, recycle and yard waste trucks may have air conditioning, but it is less effective when the doors are constantly open and the heat index is near record levels.

“If you are feeling the effects of the heat, it could mean you are already suffering from a heat-related illness like dehydration or heat exhaustion,” said Kent Harrell, Waste Management Area Vice President. “It’s critical that all workers know the warning signs of heat-related illnesses. You should also be on the lookout for symptoms in colleagues, friends and family.”

Most large trucks, vans, even SUVs conduct intense heat, especially when they are in direct sunlight for the majority of the day. We advise all drivers to know and heed the warning signs of heat-related illnesses and to drink plenty of fluids, especially water. The best way to hydrate is with water or a sports drink to replenish electrolytes.

Here are some warning signs of heat-related illnesses:

Dehydration:

Thirst

Weakness

Nausea

Muscle Cramps

Dizzy, Light-headed

Irritability

Heat Exhaustion:

Heavy Sweating

Intense Thirst

Cool Skin

Fatigue/Weakness

Loss of Coordination

Heat Stroke:

Absence of Sweating

Hot/Red/Dry Skin

Trouble Breathing

Headache

Dizziness/Confusion

Weakness/Nausea/Vomiting

It is important to act quickly when it comes to heat-related illnesses. For dehydration and heat exhaustion, you should move to a cool area and drink cool water. Elevate your legs and massage any cramps in your limbs. Provide additional cooling like a fan or ice. If you suspect heat stroke in a family member or coworker, apply water/ice to the skin to cool the victim and call 911 immediately.
