Hydrogen cyanide is liquid under standard conditions. Hydrogen cyanide easily disperses evenly in the air and can burn in the air. When the content of hydrogen cyanide in the air reaches 5.6% to 12.8%, it is explosive. Hydrocyanic acid is highly toxic. The clinical manifestations of acute hydrogen cyanide poisoning are obvious bitter almond smell in the exhaled breath of patients, and mild poisoning mainly manifests as chest tightness, palpitations, accelerated heart rate, headache, nausea, vomiting, and blurred vision. Severe poisoning is mainly manifested in a deep coma, shallow breathing, paroxysmal seizures, and even tonic spasticity. In World War II, Nazi Germany often used hydrogen cyanide as a killer gas for gas chambers.

a. Skin contact: Remove contaminated clothing immediately and rinse thoroughly with running water or 5% sodium thiosulfate solution for at least 20 minutes. Seek medical attention.
b. Eye contact: Raise the eyelids immediately and rinse thoroughly with plenty of flowing water or saline for at least 15 minutes. Seek medical attention.
c. Inhalation: Leave the scene quickly to fresh air. Keep your airways open. If breathing is difficult, give oxygen. When breathing is stopped, immediately perform artificial respiration (do not use mouth to mouth) and chest compressions. Give inhaled isoamyl nitrite and seek medical attention.
d. Ingestion: Drink plenty of warm water and induce vomiting. Wash the stomach with 1: 5000 potassium permanganate or 5% sodium thiosulfate solution. Seek medical attention.
