The symptoms of cyanide poisoning are similar to those displayed by other conditions or exposure to any of a number of chemicals, so don't assume cyanide is the cause. Death from poisoning usually results from respiratory or heart failure. Also, skin and body fluids may give off an odor of almonds. How much cyanide is too much depends on the route of exposure, the dose, and duration of exposure?
Inhaled cyanide presents a greater risk than ingested cyanide. Skin contact is not as much of a concern unless the cyanide has been mixed with DMSO , except touching the compound could lead to accidentally swallowing some of it. Unconsciousness, followed by death, could occur within several seconds of inhaling a high dose of cyanide, but lower doses and ingested cyanide may allow a few hours to a couple of days for treatment.
Emergency medical attention is critical. Because it's a relatively common toxin in the environment, the body can detoxify a small amount of cyanide. For example, you can eat the seeds of an apple or withstand cyanide from cigarette smoke without dying.
When cyanide is used as a poison or a chemical weapon, treatment depends on the dose. A high dose of inhaled cyanide is lethal too quickly for any treatment to take effect. Initial first aid for inhaled cyanide requires getting the victim to fresh air. Ingested cyanide or lower doses of inhaled cyanide may be countered by administering antidotes that detoxify cyanide or bind to it. For example, natural vitamin B12, hydroxocobalamin, reacts with cyanide to form cyanocobalamin, which is excreted in urine.
Inhalation of amyl nitrite may aid breathing in victims of cyanide and also carbon monoxide poisoning , although few first aid kits contain these ampules anymore.
Depending on the conditions, complete recovery may be possible, although paralysis, liver damage, kidney damage, and hypothyroidism are possible. Bortey-Sam, Nesta, et al.

It interferes with the normal use of oxygen by nearly every organ of the body. Exposure to hydrogen cyanide AC can be rapidly fatal. It has whole-body systemic effects, particularly affecting those organ systems most sensitive to low oxygen levels: the central nervous system brain , the cardiovascular system heart and blood vessels , and the pulmonary system lungs.
Hydrogen cyanide AC is a chemical warfare agent military designation, AC. It is used commercially for fumigation, electroplating, mining, chemical synthesis, and the production of synthetic fibers, plastics, dyes, and pesticides.
It also has a bitter burning taste and is often used as a solution in water. Water: Hydrogen cyanide AC can be used to contaminate water. Food: Hydrogen cyanide AC can be used to contaminate food. Outdoor Air: Hydrogen cyanide AC can be released into outdoor air as a liquid spray aerosol or as a gas. Agricultural: If hydrogen cyanide AC is released into the air as a liquid spray aerosol , it has the potential to contaminate agricultural products.
If hydrogen cyanide AC is released as a gas, it is highly unlikely to contaminate agricultural products. Personal Protective Equipment. If you suspect you or a loved one is experiencing symptoms of severe cyanide poisoning, seek immediate emergency medical attention.
Your outlook will depend on the type of cyanide present, the dose, and how long you were exposed. Early diagnosis and treatment are key to reducing your risk of complications. Moderate levels of acute or chronic exposure may also be resolved with quick diagnosis and treatment.
In severe cases, symptoms are often sudden and life-threatening. Immediate emergency medical attention is necessary. Learn more about arsenic poisoning, including symptoms to look out for, the most common causes, and how to treat it.
