hangar fire protection systems

this project involved a literature review of the current fire suppression systems used in aircraft hangar applications. statistics on aircraft hangar incidents, including the prevalence of fuel spills and incidences of foam discharge, in response to fire and accidental discharges were gathered through various sources and surveys. additionally, in the last 17 years, there were 44 foam system discharges in response to fire (2.6 per year) and 357 foam system discharges where a fire is not present (21 foam discharges per year creating $7 million in damages per year), which are considered to be accidental foam discharges. in light of these statistics and recent changes to the 2022 edition of nfpa 409, standard on aircraft hangars, alternative fire protection solutions were evaluated.

the report also outlines a risk-based approach for hangar fire protection. additionally, more fire incident data needs to be collected to better understand the cause, inform appropriate fire scenarios, and evaluate the performance of various fire protection solutions. to learn more about this research, register for the upcoming fprf webinar scheduled on march 24, 2022, where the principal investigators of this research, dr. jim milke, university of maryland and jack poole, poole fire protection, will be presenting on the research findings. registration is free and required to attend; register by clicking the direct link here or by visiting www.nfpa.org/webinars for more upcoming nfpa and fprf webinars and archives.

without warning, the airplane hangar fire suppression system is activated and discharges its high-expansion fire-retardant foam onto the pros and cons of hangar foam fire suppression systems safely housing aircraft in hangars poses some unique challenges. these high-value assets fire water storage tanks and fire pumps foam and/or water hand hose lines foam concentrate tanks and pumps trench drain systems for hangar floors structural, types of foam fire suppression systems, aircraft hangar fire suppression system design study, fire extinguisher for aircraft hangars, fire extinguisher for aircraft hangars, aircraft hangar foam accident.

in 2020, a foam fire suppression system went off in a delta air lines aircraft hangar at los angeles international airport. this project involved a literature review of the current fire suppression systems used in aircraft hangar applications. when wide-body aircraft with extensive wing areas become more prominent, the nfpa feared that a sprinkler discharge might not be adequate to, foam fire suppression system cost, aircraft hangar safety regulations, types of aircraft hangars, foam fire suppression system cost per square foot, aircraft hangar foam fire suppression test, foam fire suppression system design, aircraft hangar requirements, osha requirements for aircraft hangars, nfpa 409 changes, foam sprinkler systems.
