Heat Wave Safety

Excessive heat has caused more deaths than all other weather events, including floods. A heat wave is a prolonged period of excessive heat, generally 10 degrees or more above average, often combined with excessive humidity.

PREPARING FOR A HEAT WAVE

  • Listen to local weather forecasts and stay aware of upcoming temperature changes.
  • Be aware of both the temperature and the heat index. The heat index is the temperature the body feels when the effects of heat and humidity are combined. Exposure to direct sunlight can increase the heat index by as much as 15° F.
  • Discuss heat safety precautions with members of your household. Have a plan for wherever you spend time— home, work and school—and prepare for the possibility of power outages.
  • Check the contents of your emergency disaster kit (bug out bag) in case a power outage occurs.
  • 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.
  • If you do not have air conditioning, choose places you could go to for relief from the heat during the warmest part of the day (schools, libraries, theaters, malls).
  • 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.
  • Ensure that your animals’ needs for water and shade are met.

RESPONDING APPROPRIATELY DURING A HEAT WAVE

  • Listen to a NOAA (National Oceanic and Atmospheric Administration) Weather Radio for critical updates from the National Weather Service (NWS).
  • Never leave children or pets alone in enclosed vehicles.
  • Stay hydrated by drinking plenty of fluids even if you do not feel thirsty. Avoid drinks with caffeine or alcohol.
  • Eat small meals and eat more often.
  • Avoid extreme temperature changes.
  • Wear loose-fitting, lightweight, light-colored clothing. Avoid dark colors because they absorb the sun’s rays.
  • Slow down, stay indoors and avoid strenuous exercise during the hottest part of the day.
  • Postpone outdoor games and activities.
  • Use a buddy system when working in excessive heat.
  • Take frequent breaks if you must work outdoors.
  • Check on family, friends and neighbors who do not have air conditioning, who spend much of their time alone or who are more likely to be affected by the heat.
  • Check on your animals frequently to ensure that they are not suffering from the heat
