Swedish forensic data 1992-2009 suggest hydrogen cyanide as an important cause of death in fire victims.
Between 60 and 80% of all deaths related to fire are attributed to toxic fumes. Carbon monoxide (CO) is commonly thought to be the major cause. However, hydrogen cyanide (HCN) is also formed. ⋯ Over 31% had cyanide levels above 0.5 µg/g, an indication of significant HCN exposure. The percentages may be underestimates, as cyanide is quickly eliminated in blood also after death. Our results support the notion that HCN contributes more to the cause of death among fire victims than previously thought.
