In the wake of the two fatal fires in past weekend, the FDNY wants to make sure New Yorkers have working smoke detectors. Even though 97% of residences have detectors, "more than one third of them are inoperable because the batteries have been removed or are not working." Many times tenants and home owners disable the alarms because they go off due to "cooking vapors or steam from the bathroom." The FDNY says some detectors have hush functions and has more tips here. The Daily News reports that residents in a Marine Park building were saved by smoke detectors and neighbors when a fast-moving fire started yesterday. The News also offered this stat: "There were no working smoke detectors in about 70% of deadly fires in the city."
