5 P’s of Cold Weather Safety

Protect …
People: Remember to dress in layers and wear a hat and gloves outdoors. It is important to stay out of the wind and stay dry. Ensure young children and the elderly keep warm; they are the most sensitive to cold weather.
Pets: If cold weather is in the forecast, be sure to bring outdoor pets inside, or give them a warm shelter to stay in.
Plants: Cover young and cold-sensitive plants to protect them from frost and dangerous low temperatures.
Pipes: Cover exposed pipes; allow outdoor faucets to drip slowly to prevent freezing and breaking.
Practice Fire Safety: Use safe heating sources indoors. Do not use fuel-burning devices such as grills or generators indoors; they release carbon monoxide, which is a deadly gas. Also, make sure to use space heaters according to their instructions and be attentive to open flames.
