Which type of patient is most at risk for accidental exposure to cyanide?

Cyanide is a highly toxic chemical that can be released during fires, particularly when materials such as plastics or certain synthetic materials are burned. Firefighters, especially those battling structure fires, are at significant risk of cyanide exposure due to the smoke and combustion byproducts present in these environments. The inhalation of smoke can lead to the absorption of cyanide into the bloodstream, which may result in severe poisoning.

In contrast, while the other types of workers listed may be exposed to various harmful substances, their risk of cyanide exposure is generally lower compared to that of a firefighter. Auto mechanics and workers painting cars might encounter other toxic chemicals but are less likely to come in contact with cyanide specifically. Similarly, coal miners are more exposed to coal dust and other mining-related hazards than cyanide itself. Therefore, firefighters represent the group most at risk for accidental cyanide exposure due to the nature of their work in environments with potentially hazardous combustion byproducts.
