Fire fighters and fighting fires is the most hazardous job a fire fighter faces. One of those hazards is the inhalation of combustion products that comes from the smoke of a fire. The inhalation of smoke and toxic chemicals from a house fire is usually the cause of most fire related deaths. As fire burns within a structure smoke begins to fill the building with toxic chemicals such as hydrogen cyanide and carbon monoxide. These toxic chemicals are produced as plastics, polyurethane foam, and synthetic polymers are burned and melted to create cyanide toxicity.
 

Consider all the items that the common household has within the dwelling. Most homes have cleaning supplies, furniture, electronics and major appliances and these are some of the items that when burned put off toxic and lethal fumes.
 

Cyanide is just one of many toxic fumes that is produced during a fire. Other fumes that are created from a burning house fire are methane, chlorine, acetic acid, and ammonia among many other deadly gases mixed with smoke and fire.
