some fire engines have been known to stop running
because the atmospheric oxygen was depleted by the
fire and the motor had none for the carburator to
mix with the fuel. firefighters have become trapped
without the possibility of escape due to this.

around here the homeowners are cautioned to clear all
vegetation 100 feet from the house--they used to say
30 feet...but regs. have changed. this includes ladder
fuels--ones that would allow a fire to climb from the
ground to the crown (tree tops) unfortunately we have
60,000 acres of trees burned last year, and still there
is fire danger from standing dead timber--cooked by the
sun for a year, and may topple from wind.
