- Abstract
- Use of a Halon 1301 fire suppression system was evaluated in regard to increasing escape time during a ground crash situation with an internal cabin fire. Smoke, temperature, carbon monoxide, oxygen and Halon 1301 levels were continuously monitored. A sampling system for collecting hydrogen fluoride (HF) was used. The use of a curtain to inhibit the spread of HF also was examined. The results indicated that in order to minimize the HF concentrations, the fire should be extinguished prior to the opening of cabin exits. The use of a curtain to partition the cabin greatly reduced the spread of HF from the fire zone to the protected section. Test results also indicated that a system maufunction causing Halon 1301 concentrations less than those needed to extinguish a fire could produce very high HF levels.
