Recalled sprinkler heads were found at four Fall River sites following Gabriel House fire. Officials say there could be more.

"Recalled fire sprinklers may still exist at properties in Fall River and beyond, the city's fire department warned Monday, just months after the deadly Gabriel House assisted living facility fire. The Fall River Fire Department said four residential properties have recently replaced their sprinkler heads after routine inspections found some that had been recalled 24 years ago. The department warned in a news release that more of the recalled sprinklers could still be found in Fall River and other parts of Massachusetts."

""Our mission is to protect the lives and safety of our residents," Fall River Fire Chief Jeffrey Bacon said in a statement. "We are pleased that the affected property owners acted immediately and achieved full compliance. But this issue is not yet behind us. We need the continued diligence of sprinkler contractors and building owners to help identify and correct similar problems wherever they may exist.""

Recalled Central Sprinkler Company sprinkler heads manufactured between the mid-1970s and 2001 were identified during routine inspections at four residential properties in Fall River, including a group home, boarding houses and a shelter. The recalled heads were part of a 2001 U.S. Consumer Product Safety Commission voluntary recall citing potential rubber O-ring seal failures that could prevent activation in a fire. Property owners replaced the recalled heads after notification and said they had been unaware of the recall. Fall River Fire Chief Jeffrey Bacon urged continued diligence from sprinkler contractors and building owners to identify and correct similar problems. Findings follow a July five-alarm blaze at Gabriel House that killed ten people and injured dozens.
