It is not inconceivable for someone to use a space heater where tile cement is being put down or lacquers are being applied. Other sources include cleaning agents, adhesives, and some aerosol products. Any product using a solvent other than water is a potential source of fire or an explosion. There are other fire hazards, such as curtains, paper, carpets or anything in the home that is combustible. Carbon monoxide poisoning deserves the most attention.
Carbon monoxide is referred to as the silent killer.
People overcome by carbon monoxide usually have no warning. Some may notice a slight tightness in the chest, but this may not be a major factor since the brain is being dulled by the absence of oxygen-rich blood and the warning is easily ignored or misunderstood. The typical signs and reactions of acute carbon monoxide poisoning are headache, dizziness, drowsiness, nausea, vomiting, collapse, coma and death. Loss of consciousness occurs at about 50 percent carboxyhemoglobin level. The precise moment depends on the duration of the exposure, ambient temperature, and the health and metabolism of the individual.
