Cold Weather Tips
There are some steps you can take to keep your vehicle running and your house warm:
When it comes to your home, experts advise:
The Chicago Fire Department does not recommend using space heaters; however, if used, be sure they are UL certified and at least 3 feet from anything that can ignite. The use of a space heater in children's rooms should be monitored closely as children sometimes move them close to or into the bed with tragic results, officials said. If extension cords are used, they should be rated at 15 amps minimum and never put cords under carpet. With the added demand on furnaces and boilers, CFD also reminds residents they are required by ordinance to have working carbon monoxide detectors to protect against carbon monoxide leaks from a heating system that could be fatal over time, and to keep smoke detectors in working order.

Cold weather tips for pets
As for your furry friends, before you bring your cats, dogs or other pets inside for the night, PAWS Chicago warns owners of outside dangers they may have encountered, including exposure to antifreeze.
"It may have spilled when you're pouring into your car, your neighbor may have been pouring it into their car and spilled some on the ground," said Ajmie Gay with PAWS Chicago. "Dogs are notorious for just licking the sidewalk or just ingesting the snow that might have been around but antifreeze or the salts."
PAWS Chicago said if you buy salts, it's best to stick with pet-safe salts. Anything else can be toxic to your pet.
"The salt actually causes chemical burns," Gay added. "So you may not see it at first, but the longer it sits on their paws you may actually see like ulcerations on their paws because it builds up, and then if they're licking their paws, they're going to have those burns inside their mouth."
