Hot weather often brings problems for people that are unprepared or inexperienced in dealing with heat and outside activities. Persons with a history of high blood pressure, heart problems need to be especially vigilant. Certain prescription medications may also decrease your heat tolerance. Check with your doctor who prescribed the medications.
Heat cramps, heat exhaustion and heat stroke can ruin your day and yes kill you if you are unprepared.
We are all used to reading the thermometer but there is another number we need to be aware of when working events or call-outs in warm weather.
The Heat Index is a measure of the apparent temperature of the air by factoring in the effects of relative humidity.
For instance: an air temperature of 95 degrees with a relative humidity of 50% has a heat index of 107. That means it feels like and has the effect on your body of a 107 degree day. Heat indexes above 110 degrees are considered highly dangerous. The best way to deal with summer heat is to be prepared.
Carry at least two quarts of water with you. Do not rely on water at the event. Make sure you drink some water every 15-20 minutes. Do not drink soda or highly sugared drinks.
Eat a small snack midway through the event, but avoid protein rich foods -- they increase metabolism and overall body temp.
Wear light colored loose fitting cotton clothes. Polyester clothing is great, jeans are too hot. Wear a hat ( the traditional straw western Stetson is ideal.) Use sun block and sunglasses.
Slow down, plan your work, try to stay in the shade. Avoid standing on concrete or asphalt surfaces that hold in heat.
There are three types of heat emergencies that you need to be familiar with. Watch out for theses symptoms in yourself, and fellow members and the public during warm weather.
Heat Cramps:
Cramps or muscle spasms in the abdomen, arms or legs. Have the person stop activity and drink plain water at room temperature or a Gatorade type drink mixed half and half with water. Avoid ice cubes in the drink.
Heat Exhaustion:
Heavy sweating, paleness, muscle cramps, weakness, dizziness, headache, nausea or fainting. Cool the person down and get them drinking. They are done for the day. Seek medical attention if the person has a history of high Blood Pressure or cardiac problems.
Heat Stroke:
Extremely high body temperature. Red, hot, dry skin. The victim will no longer be sweating, rapid pulse, throbbing headache, dizziness, nausea, confusion and unconsciousness. Remove unnecessary clothing. Call 911 and cool the victim down with water or a hose. If ice is available put icepacks under the armpits, around the neck and in the groin area.
In conclusion experience has shown that being aware of the dangers of working in hot weather conditions reduces the risk of heat problems and provides a more enjoyable experience.
