angar fires are an all too real concern
and having the right suppression
systems in place should one
occur is critical. The National Fire
Protection Association (NFPA)
standard on aircraft hangars
(NFPA 409) gives guidance to what
suppression systems a hangar needs.
Last year, the 2022 edition of NFPA 409 was
published and with it revisions to the guidelines
around hangar suppression systems - namely foam
fire suppression.
To get the latest on aircraft fire suppression
needs and what the change to NFPA 409 means,
AMT spoke with Megan Eisenstein, managing
director, industry affairs & innovation, NATA,
and Doug Fisher, principal fire protection engineer,
Fisher Engineering, Inc. Eisenstein sits on the
NFPA's Technical Committee on Airport Facilities,
with Fisher as the NATA's designated alternate.
AMT: To lay the foundation, what are some of
the leading causes of hangar fires?
According to a 2019 University of Maryland report
on the review of foam fire suppression system discharges
in aircraft hangars, there were 174 incident
reports of foam system discharges between 2004
and 2019. The 174 incidents include 37 incidents
where the foam systems discharged in response to a
fire and 137 incidents where there was an accidental
foam discharge, i.e., no fire was present. None of the
37 incidents involved a fuel spill from an aircraft.
The leading causes of incidents with foam discharge
in response to fire were:
* Fuel spill
* Electrical
* Started in office or living quarters
* Boiler
* Compressor
* GPU short
* Hot glue gun left plugged in
