The industrial chimneys used to help keep the indoor air cool can sometimes cause a fire if they’re not properly maintained, according to the American Fire Prevention Association.
In its latest annual report, the fire safety group says that the fire risk is higher with chimney stacks, because they’re less secure.
Chimney stacks are located in the basement, and the fire hazard is increased in areas where the chimney stack is located.
The AP first reported on the chimneys in March, saying the fire danger increases if the stack is not secured to the basement.
In an April 3 email to residents, the city’s Fire Marshal’s Office said that in addition to the risk of fire, “the chimneys and other supporting structures can also contribute to the formation of fire hazards in areas of high activity, such as the basement and the crawl space.”
The email also warned that in cases of chimney failure, residents should check for smoke and flames from their homes.
