When exposed to smoke, hydrogen cyanide may play a role in rendering firemen and bystanders incapable of performing self-rescue.
HCN is a toxin that spreads throughout the body; it is hazardous because it inhibits cytochrome oxidase, which stops cells from using oxygen. Loss of awareness, respiratory arrest, and finally death arise from inhibition of the last stage of electron transport in brain cells.
Higher HCN exposures cause cardiovascular collapse, tremors, cardiac arrhythmia (which may not manifest for two to three weeks after the fire exposure), coma, respiratory depression, and respiratory arrest. Inhaling minute concentrations of hydrogen cyanide can result in headaches, weakness, nausea, and vomiting. Larger doses might result in fainting, convulsions, gasping, fast pulse, irregular heartbeat, and even death. In general, the severity of the symptoms increases with the seriousness of the exposure.

The author's name is Upton Sinclair.
Upton Sinclair was an American journalist and novelist. <em>'The Jungle', </em>published in 1905, exposed the harsh reality of immigrants in the United States, particularly those who worked in the meat industry.
Sinclair describes the appealing conditions in meat packing plants in the USA as a way to advance socialism. The book concentrates around the life of a Lithuanian immigrant family who came to the USA to live the American dream. It portrays working class poverty, the lack of social supports, harsh living and working conditions in the factories.
"The Jungle" did not live up to its author's expectations as most readers were more concerned about the quality of meat being packed in the factories, health violations and unsanitary practices, than the plight of the workers. This public outcry led to the creation of the Federal Meat Inspection Act of 1906.
