For background, NFPA 409 and the model building
codes define fire protection criteria for aircraft
hangars based on " Groups. " One of the determinations
for a Group II hangar is a door height of 28
feet or less. This height limit was put into the codes/
standards a long time ago to limit the quantity of
fuel that might be in an aircraft hangar by limiting
the size of the aircraft that could fit into a hangar.
The thought process was that an aircraft with a tail
height less than 28 feet holds significantly less fuel
than an aircraft with a tail height greater than 28
feet. Over the past 40 or so years, changes in aircraft
design, aerodynamics, fuel efficiency and fuel tank
size have possibly made this distinction, based on
tail height, obsolete.
For the next edition of NFPA 409, NATA will
advocate to change the door height maximum for
Group II hangars. Increasing the door height poses
no additional risk, as it does not allow a greater
volume of fuel to be present, but does provide additional
flexibility to aircraft manufacturers, FBOs
and hangar operators.
AMT: What final advice do you have for our
readers when it comes to their hangar's fire
safety and suppression?
* Ensure proper and complete ITM is being performed
on your system.
* Understand how your system operates and how to
properly shut it down in the case of an inadvertent
discharge, including how employees will safely
evacuate the building and how accountability
of employees will occur.
* Retain the services of a qualified design professional
to evaluate if foam is required for your
facility based on the current requirements in
NFPA 409, 2022 edition and industry guidance.
If it's not, have the design professional engage
in discussions with the AHJ to determine if the
foam can be removed.
* Retain the services of a qualified professional
engineer to evaluate your current system installation
and make recommendations to increase
reliability of the system and reduce the potential
for an inadvertent discharge.
