FORT WAYNE, Ind. (WANE)— As nights with below-zero wind chills are expected Wednesday and Thursday, the Fort Wayne Fire Department (FWFD) gave tips to heat your home safely. In the past five days, FWFD has responded to two large fires caused by a "faulty heating/air conditioning unit" and "possibly...by a space heater sitting too close to combustible items." Saturday's fire at Baldwin Creek Apartments on Fort Wayne's northeast side displaced dozens of people and condemned an entire building. Man dies days after escaping house fire in Yoder FWFD Assistant Chief of Community Risk Reduction Jonathan Flickinger said that combustible materials include most fabrics. He said space heaters get hotter than one may think, so make sure they're at least three feet away from couches, upholstery, curtains, drapes, blankets, etc. "Another thing to be considerate of is to make sure you're not using space heaters in the bathroom," Flickinger said. "You don't want to get water on the elements." Additionally, Flickinger said to place space heaters on a solid, flat surface. Even carpet can pose a risk. "You think about carpet," Flickinger said. "Well, that's got some combustible capabilities there. So, you want to make sure you're being extra cautious when you're around that type of flooring." According to Flickinger, what you're paying for a space heater doesn't matter as much as it's UL listing. He recommends buying space heaters with that seal on them. A UL listing is a safety and compliance certification mark that indicates a product has passed rigorous testing by Underwriters Laboratories (UL). He also suggested to look for a space heater with an automatic feature that allows the heater to shut itself off completely if it is tipped over. Another tip Flickinger gave is to plug a space heater directly into an outlet, not a surge protector or extension cord. "It's drawing a lot of power," Flickinger said. "And so it really needs to go straight into that outlet. That's what it's designed to do."
