Found the safety alert, and it involved a Buddy heater.
SAFETY ALERT!
Fire Safety in Camps
Last Wednesday (08/09), at around 3 AM, a Weatherport-type tent at a remote
BLM camp caught fire and burned down. A detailed report is not yet
available, but initial reports are that a propane-fueled radiant heater
ignited a sleeping bag, forcing the occupant to evacuate the tent in the
middle of the night. While he was fortunately not injured, this was
obviously a very serious close call. Suffering severe burns several (or
many) hours away from medical assistance would have been a truly horrible
experience.
Most portable propane heaters are not rated for indoor use (including
tents) because of carbon monoxide issues. However, there are a handful of
radiant propane heaters on the market that are approved for indoor use
because they have a built-in control that shuts the heater off when
inadequate levels of oxygen are detected. These are now being used by BLM
personnel around the state. There are two very important things to remember
about using these heaters:
Very close attention must be paid to maintaining adequate distances from
combustible materials. The Buddy Heater, for example, requires only 6"
of clearance for combustibles from the sides of the heater, but requires
a full 30" clearance above the top and 24" from the front. These areas
must be kept clear of all combustible materials at all times when the
heater is in operation.
"Rated" doesn't necessarily mean "failure proof." In fact, these radiant
style heaters are not approved for indoor use in Canada, because the
Canadian government simply isn't convinced that a sleeping person should
bet their lives on an inexpensive device to detect oxygen deficiencies.
Personally, I'm inclined to agree with the Canadian government, because
detecting oxygen deficiencies is a pretty rough substitute for
monitoring CO levels.
Bottom Line: Use only heaters rated for indoor use, scrupulously maintain
clearances around the heater, and make sure your tent has an opening near
the heater for fresh air to enter.
Remember- Safety is a habit you can live with.
