Summer heat waves have become more frequent and increasingly intense over the past 20 years. In a normal year, about 175 Americans are killed by extreme heat. Among natural disasters, only extreme cold, not hurricanes, tornadoes, floods, or earthquakes, takes a greater toll. Based on international protocols, Extreme Heat Survival focuses on what people can do before, during and after a heat wave to protect themselves and their property. Also included in each guide are smartphone QR codes that link to the websites of various emergency services agencies.
