How to Protect Yourself and Those You Love In Case of Extreme Heat


SOURCE:  http://www.ready.gov/heat

Heat kills by pushing the human body beyond its limits. In extreme heat and high humidity, evaporation is slowed and the body must work extra hard to maintain a normal temperature.

Most heat disorders occur because the victim has been overexposed to heat or has over-exercised for his or her age and physical condition. Older adults, young children and those who are sick or overweight are more likely to succumb to extreme heat.

Conditions that can induce heat-related illnesses include stagnant atmospheric conditions and poor air quality. Consequently, people living in urban areas may be at greater risk from the effects of a prolonged heat wave than those living in rural areas. Also, asphalt and concrete store heat longer and gradually release heat at night, which can produce higher nighttime temperatures known as the "urban heat island effect."

A heat wave is an extended period of extreme heat, and is often accompanied by high humidity. These conditions can be dangerous and even life-threatening for humans who don't take the proper precautions.

Before Extreme Heat

  • To prepare for extreme heat, you should:
  • To begin preparing, you should build an emergency kit and make a family communications plan.
  • Install window air conditioners snugly; insulate if necessary.
  • Check air-conditioning ducts for proper insulation.
  • Install temporary window reflectors (for use between windows and drapes), such as aluminum foil-covered cardboard, to reflect heat back outside.
  • Weather-strip doors and sills to keep cool air in.
  • Cover windows that receive morning or afternoon sun with drapes, shades, awnings, or louvers. (Outdoor awnings or louvers can reduce the heat that enters a home by up to 80 percent.)
  • Keep storm windows up all year.
  • Listen to local weather forecasts and stay aware of upcoming temperature changes.
  • Know those in your neighborhood who are elderly, young, sick or overweight. They are more likely to become victims of excessive heat and may need help.
  • Be aware that people living in urban areas may be at greater risk from the effects of a prolonged heat wave than are people living in rural areas.
  • Get trained in first aid to learn how to treat heat-related emergencies.

During Extreme Heat

 

 What you should do if the weather is extremely hot:
  • Listen to NOAA Weather Radio for critical updates from the National Weather Service (NWS).
  • Never leave children or pets alone in closed vehicles.
  • Stay indoors as much as possible and limit exposure to the sun.
  • Stay on the lowest floor out of the sunshine if air conditioning is not available.
  • Postpone outdoor games and activities.
  • Consider spending the warmest part of the day in public buildings such as libraries, schools, movie theaters, shopping malls, and other community facilities. Circulating air can cool the body by increasing the perspiration rate of evaporation.
  • Eat well-balanced, light, and regular meals. Avoid using salt tablets unless directed to do so by a physician.
  • Drink plenty of water; even if you do not feel thirsty. Avoid drinks with caffeine. Persons who have epilepsy or heart, kidney, or liver disease; are on fluid-restricted diets; or have a problem with fluid retention should consult a doctor before increasing liquid intake.
  • Limit intake of alcoholic beverages.
  • Dress in loose-fitting, lightweight, and light-colored clothes that cover as much skin as possible. Avoid dark colors because they absorb the sun’s rays.
  • Protect face and head by wearing a wide-brimmed hat.
  • Avoid strenuous work during the warmest part of the day. Use a buddy system when working in extreme heat, and take frequent breaks.
  • Check on family, friends, and neighbors who do not have air conditioning and who spend much of their time alone.
  • Avoid extreme temperature changes.
  • Check on your animals frequently to ensure that they are not suffering from the heat. Go to a designated public shelter if your home loses power during periods of extreme heat. Text SHELTER + your ZIP code to 43362 (4FEMA) to find the nearest shelter in your area (example: shelter 12345).
First Aid for Heat-Induced Illnesses
Condition
Symptoms
First Aid
Sunburn
Skin redness and pain, possible swelling, blisters, fever, headaches
Take a shower using soap to remove oils that may block pores, preventing the body from cooling naturally.
Apply dry, sterile dressings to any blisters, and get medical attention.
Heat Cramps
Painful spasms, usually in leg and abdominal muscles; heavy sweating
Get the victim to a cooler location.
Lightly stretch and gently massage affected muscles to relieve spasms.
Give sips of up to a half glass of cool water every 15 minutes. (Do not give liquids with caffeine or alcohol.)
Discontinue liquids, if victim is nauseated.
Heat Exhaustion
Heavy sweating but skin may be cool, pale, or flushed. Weak pulse. Normal body temperature is possible, but temperature will likely rise. Fainting or dizziness, nausea, vomiting, exhaustion, and headaches are possible.
Get victim to lie down in a cool place.
Loosen or remove clothing.
Apply cool, wet clothes.
Fan or move victim to air-conditioned place.
Give sips of water if victim is conscious.
Be sure water is consumed slowly.
Give half glass of cool water every 15 minutes.
Discontinue water if victim is nauseated.
Seek immediate medical attention if vomiting occurs.
Heat Stroke
( a severe medical emergency)

High body temperature (105+); hot, red, dry skin; rapid, weak pulse; and rapid shallow breathing. Victim will probably not sweat unless victim was sweating from recent strenuous activity. Possible unconsciousness.
Call 9-1-1 or emergency medical services, or get the victim to a hospital immediately. Delay can be fatal.
Move victim to a cooler environment.
Removing clothing
Try a cool bath, sponging, or wet sheet to reduce body temperature.
Watch for breathing problems.
Use extreme caution.
Use fans and air conditioners.

Happy National Doughnut Day!

Happy National Doughnut Day!

Did you know that the first Friday in June is designated as National Doughnut Day?  National Doughnut Day actually stretches back all the way to 1938, when the Salvation Army initiated the holiday to commemorate the volunteers who passed out doughnuts to soldiers on the front lines in World War I. According to Wikipedia, it was started by the Salvation Army as a fundraiser and continues as such today.

Also from Wikipedia, "Soon after the US entrance into World War I in 1917, The Salvation Army sent a fact-finding mission to France. The mission concluded that the needs of US enlisted men could be met by canteens/social centers termed "huts" that could serve baked goods, provide writing supplies and stamps, and provide a clothes-mending service. Typically, six staff members per hut would include four female volunteers who could "mother" the boys. These huts were established by The Salvation Army in the United States near army training centers.

About 250 The Salvation Army volunteers went to France. Because of the difficulties of providing freshly baked goods from huts established in abandoned buildings near to the front lines, two Salvation Army volunteers (Ensign Margaret Sheldon and Adjutant Helen Purviance) came up with the idea of providing doughnuts."
