ILDFA

The Ignitable Liquid Drainage Floor Assembly (ILDFA) is an active fire protection system designed to respond to Class B fires inside infrastructure such as aircraft hangars, refineries, chemical plants, manufacturing facilities, etc.[1][2] ILDFA serves as an alternative to traditional foam-based fire suppression systems, addressing both fire safety risk and environmental concerns.[1][3][4][5]

Overview

ILDFAs use a dual approach, combining a water-based fire suppression system in conjunction with a hollow, perforated flooring system to drain and remove spilled flammable liquid.[6][7] This approach reduces the risk of pool fires inside infrastructure diverting leaked fuel away from potential ignition sources, enhancing safety.[6]

Adoption in NFPA 409 2022 Edition

The Ignitable Liquid Drainage Floor Assembly (ILDFA), has been included in the National Fire Protection Association (NFPA) 409 as the industry's standard for aircraft hangars fire protection in the 2022 edition.[4][1][8]

Additionally, the U.S. Navy, U.S. Air Force, and U.S. Army have begun implementing ILDFA technology at various bases such as Naval Air Station Point Mugu further demonstrating ILDFA's role in safely containing hazardous flammable liquid spills.[1][9][10][11][12]

Recognition

ILDFA has received recognition and acceptance from prominent organizations in the fire protection and aviation sectors, including the National Fire Protection Association (NFPA) 409, Factory Mutual Global, and the Department of Defense (DOD).[13]
