Hi Bill.. our club 'rules' now include a fire extinguiser being handy for gas powered applications... minimal grumping occured when this motion was made.. a guy had a flame-up with a gas engine; the need was obvious.
Most folks, when confronted with a new requirement (any requirement) generally start hopping on the 'constitutional rights' bandwagon and begin to exaggerate the implications and impact of the 'new' requirement, whatever it may be.
Our local electric club recently instituted a 'no unattended charging' requirement for li-poly setups.. lordy; you shoulda heard the howling on that one...
Bottom line, if it helps preserve the flying site and improve the saftey of operations for your club it should be discussed by the membership and voted into the club by-laws.. if the case can't be made and the membership shoots it down, then yah did your part to raise awareness at the least.. which might save a plane or two regardless.
Good luck!
