Fire extinguisher and lipo rules
Fire extinguisher rule
#) Because our aircraft rely on potentially flammable power sources and there is a chance for fire to cause personal injury, property damage, and "grass" fires, all pilots with aircraft at the field must have in their pit area, visible and easily reachable, a fire extinguisher in good working condition. Recommended are ABC-rated (red) types such as those made by Kidde. (At this time, yellow class D copper-based extinquishers to extinguish lipo fires are not readily available and not required). Final determination of suitability will be determined by the club Safety Officer or other club officer.
Lipo safe rule
##) Because Lipo and other lithium batteries are at highest risk of fire during charging and conventional fire extinguishers do not put out lithium fires, all lithium containing batteries must be contained in fire-proof / fire-resistant containers while being charged at the field. This applies whether the charging is done inside or outside a vehicle. Charging batteries must be completely contiained in the container except for the charging and balance wires exiting the container. Acceptable containers include "lipo safe bags" made of Nomex © or equivalent, covered metal boxes (ammo boxes, for example), or covered, heatproof ceramic containers. Final determination of suitability will be determined by the club Safety Officer or other club officer.
