THE ISSUE

Commercial airliner costs can exceed $200 million, while military aircraft can cost substantially more. This makes high-performance systems that detect heat or flames and actuate fire suppression systems essential for safeguarding aircraft assets as well as hangar structures and human life.

Solutions must address hangars’ unique challenges:

– Large detection expanse that contains sizable obstacles
– Large hangar doors that create variable conditions
– Radio-frequency interference (RFI) that can create false alarms

Today’s industry-leading standards for hangar fire protection come from the U.S. military and call for optical flame detectors such as the X3301 Multispectrum IR detector from Det-Tronics. Beyond equipment choices, a superior installation takes expertise with standards, codes and placement.

THE ANSWER

One size does not fit all. A hangar’s unique characteristics require special planning, design and implementation considerations:

1. Rejecting false alarms
2. Building in redundancy
3. Speeding detection and decision making
4. Integrating fire and gas detection and suppression

Guidelines on protecting aircraft hangars can be found in FM Global Property Loss Prevention Data Sheets 7-93 (April 2017), Unified Facilities Criteria (UFC) 4-211-01 (13 April 2017) & NFPA 409 and 410.
