Tips to Stay Safe in the Heat this Summer: Excessive heat is a danger to anyone, especially those with respiratory issues, people who work outdoors, children and the elderly. Make sure outdoor pets have safe shelter and cool water. Cars turn into ovens in a matter of minutes so be sure to check the back seat and never leave children or pets in the car. Wear light-weight, light-colored, loose-fitting clothing and stay hydrated! Avoid strenuous outdoor activities, enjoy air conditioning whenever possible and if you're working in the heat make sure to take breaks often and drink plenty of water.
Now is a good time to check your cars for loose tire tread or parts—anything that could easily spark a fire. In addition, make sure you have a go bag and working flashlights in case of an emergency or power outage. Also, prune and trim trees and shrubs to make a defensible space around your home.
