In addition to carbon monoxide there will probably be substantial proportions of such vapors as hydrocyanic-acid gas and hydrogen sulfide, both infinitely more deadly; plus ammonia, which is about as lethal as the dreaded CO.
In New York a few years ago a woman dozed off with a cigarette in her hand while reading h erSunday newspaper. The cigarette fell into the papers on the floor, which took fire and wakens ed her. She dashed to the phone and called firemen. Then she tried to put out the blaze. When the firemen arrived the fire was out— and so was the woman. The burning papers generated enough gas to kill her. In Ohio a burning Christmas tree—quickly smothered with a rug—asphyxiated a baby sleeping upstairs in its crib although persons in the same room with the fire suffered no ill effects.

While burning gasoline seems ominous enough to most of us, fumes from burning wood can be more lethal. Also, the organ of smell plays tricks: the occupants of a room may be totally unaware of a gas odor which a person entering the room will immediately detect.
Both carbon monoxide and hydrogen sulfide, however, give warning before striking: a headache. In a smoky atmosphere the onset of even a slight headache means: Get out! In a nonsmoky but closed room it suggests ventilation and checking for gas.
The heaviest doses of carbon monoxide are usually found in the first stage of a fire—especially a slow starter—when the householder is mostlikely to be there. And two deep breaths of air containing only two per cent can kill in three minutes. i
Don’t monqey around with a going fire, particularly a smoky one, in a cellar, attic or clothes closet. Shut the door on it and call the firemen.
Don’t try to judge the danger of smoke by its color ordensity. “Thin” smoke can be very toxic, depending upon what’s burning.
