Safespill Ignitable Liquid Drainage Floor Assembly (ILDFA)
Principal: Safespill (USA)
Conventional hangar protection waits for a fuel fire, then floods the building with foam — damaging aircraft, creating a PFAS cleanup problem, and taking the facility out of service for days. Safespill takes the opposite approach: the floor itself removes the spilled fuel before it can ignite into a pool fire.
The system is a hollow extruded marine-grade aluminium floor with a perforated top surface. Spilled liquid drains instantly through the perforations into channels below, is carried to a trench system, and is routed to an oil-water separator or containment. If a spill does ignite, the assembly knocks the flame down rapidly. It uses only gravity, water and aluminium — no chemicals, no foam concentrate, no agent to store or replace.
Key Features
- Removes ignitable liquid before a pool fire can develop
- Chemical-free and PFAS-free — no AFFF, no high-expansion foam, no toxic runoff
- No risk of accidental foam discharge damaging aircraft or equipment
- Faster flame knockdown than foam-based alternatives
- Eliminates drip pans and the downtime associated with routine fuel spills
- No need to defuel aircraft before maintenance
- 50+ year design life with minimal maintenance and low lifecycle cost
- Modular trench design simplifies facility infrastructure
