20. 3-20 Lessons Learned: Fire Suppression Anticipate how zero-g will affect combustion & fire fighting Use off-the-shelf equipment when cost effective

21. 3-21 Activity 3-1 Considering Alternatives to Halon 1301

22. 3-22 Summary Detection –Cannot ignore zero-g –After implementation, engineering change is costly –Crew need to be able to see readouts –In the future, earlier sensing & shut down is needed to prevent equipment damage Suppression –Consider zero-g testing –Consider benefit of existing & new –Should be non-toxic
