The Abington Township Fire Marshal’s Office announced today that an investigation of the SPS Technologies fire on February 17 has determined that the area of the compressed air system infrastructure was the area of origin.

However, the investigation “was unable to determine the specific failure in the system. In accordance with NFPA 921, when multiple hypotheses cannot be eliminated, a fire is to be deemed undetermined,” the notice said. “Accordingly, due to numerous potential hypotheses as to what failed within the compressed air system infrastructure remaining, the fire cause has been deemed Undetermined.”

The fire has been classified as “Accidental”, according to the Bureau of Alcohol, Tobacco, Firearms and Explosives classification system, based off of the results of the investigation.

The announcement comes a day after SPS Technologies representatives publicly presented their plans for a new aerospace facility at the Jenkintown site.

Abington fire marshal Chris Platz also noted that:

• There was what appears to be a failure of the compressed air system infrastructure within the building, resulting in numerous explosions and fires throughout.
• There is no indication of an intentionally set fire within the structure.
• There is no indication of any negligence/malicious intent on behalf of SPS Technologies that led to this fire.

“Thank you to all responding agencies and participants who contributed to the investigative efforts of the Abington Township Fire Marshal’s Office including SPS Technologies, whose full cooperation and assistance was imperative to a thorough investigation,” the notice said.
