Commercial, non-standard heaters,
including
unvented
kerosene
or
propane heaters, are
not approved
for
Army
use.
Never
heat
your
tent with them. They emit
carbon
monoxide gas
that could make you
sick or even kill you.
Some commercial models tend to
leak fuel around the valves. Others
are prone to tip over. In other words,
they’re
fre hazards
.
Remember, no commercial heaters
meet Army Feld standards. So stay
warm and safe: Choose the ±OSH.
For more information on the FOSH, go to the Defense Supply Center
