hot ash
Still-burning fire remnants
Hot ash is the smoldering residue left after a fire—wood, coal, or cigarettes that retain enough heat to reignite or cause burns.
The term appears in fire safety warnings and disposal instructions: Never put hot ash in a plastic container.
Firefighters and campers treat hot ash as a serious hazard, since it can stay dangerously warm for days under a deceptive gray surface.
