by a flood and/or wind, 3) telephone lines, even underground wiring,
could be disabled - need an alternate means of canmunication, 4) phone
numbers - need phone numbers of individuals with expertise in cyanide
spills, 5) the means for evacuating residents is not clear, 6) gas
masks - people need training in usage, 7) emergency shelters - location
of these should be established/published, etc.
