Extreme Heat
What is a Heat Hazard?
Doing too much on a hot day, spending too much time in the sun or staying too long in an overheated place can cause heat-related illnesses. Know the symptoms of heat disorders and overexposure to the sun, and be ready to give first aid treatment.
Before
- Contact your local emergency management office or American Red Cross chapter for information on extreme heat.
- Install window air conditioners snugly.
- Insulate spaces around air conditioners for a tighter fit.
- Close any floor heat registers nearby.
- Use a circulating or box fan to spread the cool air.
- Keep heat outside and cool air inside.
- Install temporary reflectors, such as aluminum foil covered cardboard, to reflect any heat back outside.
- Keep the cool air inside by weather-stripping doors and windowsills.
- Consider keeping storm windows up all year. Storm windows can keep the heat of a house in the summer the same way they keep the cold out in the winter.
- Check air-conditioning ducts for proper insulation.
Heat Disorders
