What should I do if I am exposed to cyanide?
Seek medical care right away, even if you are not sure you were exposed.
- Do not make yourself vomit if you have swallowed cyanide. Cyanide in your vomit could contaminate others, or damage your airway.
- Remove and bag all items on your body, including clothes, contacts or glasses, and jewelry. Try not to touch affected items with bare hands, or try to touch only a small part of each item. Put affected items into a bag. Put the bagged items into another bag. Let emergency responders take care of the bags. Do not put affected contacts back in, even if they have been rinsed. Eyeglasses can be washed and worn again.
