QUINCY, Mass.The National Fire Protection Association (NFPA) is emphasizing “the critical fire risks associated with smoking in the presence of medical oxygen” and offering the public and the media resources on the topic.

The Bristol County District Attorney’s Office and the Massachusetts State Fire Marshal’s Office this week provided an update on the ongoing investigation into the fatal fire at Gabriel House, an assisted living facility in Fall River, Mass. Investigators confirmed the fire began in a second-floor resident room and remains classified as “undetermined” under NFPA 921 guidelines.

Investigators also emphasized that the presence of medical oxygen contributed significantly to the rapid spread and lethality of the fire, which claimed 10 lives.
