And Sunday in the Bronx, a fire in a high-rise apartment building after a space heater malfunctioned.

Eyewitness News reporter Kerri Corrado spoke with national experts about fire safety.

As the temperatures drop, many people are trying to find ways to heat their homes. Fire officials want you to be safe in doing so.

Fire prevention is now at the forefront following two deadly apartment fires. One on Sunday in the Bronx killed 17 people, and the other on Jan. 5 in Philadelphia’s Fairmount neighborhood, killed 12 people.

“We know these fires should not claim this many lives,” Shane Ray said.

Ray and Ron Siarnicki, both former fire chiefs, have been fighting to retrofit sprinklers in older high rises and multi-family homes that were never equipped with them in the first place.

They say there is no federal law to do so and that needs to change.

“The buildings in these fires do not have fire sprinklers. They were built before the codes and standards required fire sprinklers in them but our push is to retrofit these buildings because they are high-risk occupancies,” said Ray, president of the National Fire Sprinkler Association.

They say if sprinklers were present in the apartment buildings, they believe it would have made a difference.

“If the building was adequately protected with fire sprinklers these fires would have been kept small and allowed firefighters time to arrive, evacuate, and rescue the people,” Ray said.

As the investigations into both fires continue, firefighters are also offering tips to stay safe as people try to find ways to heat their homes and stay warm as the temperatures drop.

“You need to have an exit plan, you need to know what to do if the smoke alarm goes off, you need to know what to do if the food in the stove catches fire, and you need to look at the safety components related space heaters, alternative heating systems,” said Siarnicki, executive director of the National Fallen Firefighters Foundation.
