Proper Disposal of Hot Ashes
Several times a year we respond to fires that are caused by improper
disposal of hot coals or ashes from fireplaces, grills, or mobile
fireplaces designed for use on decks or patios. The scenario is often
similar . . . "I thought the coals were cool", or even worse, "I didn't
even think about it . . ."
The fact is that coals and ashes from fires can remain hot enough to
start a fire for many hours or perhaps days after you think the fire is
out. The exact amount of time for complete extinguishment and cooling
depends on many factors such as how hot the fire was, what was burning,
how much unburned fuel remains, etc. To be safe, simply treat all ashes
and coals as hot, even when you think they had time enough to cool.
