Hydrogen cyanide (formerly known as prussic acid) is a chemical compound with the formula HCN and structural formula H−C≡N. It is a highly toxic and flammable liquid that boils slightly above room temperature, at 25.6 °C (78.1 °F).

Hydrogen cyanide poisoning is marked by abrupt onset of profound toxic effects that may include syncope, seizures, coma, gasping respirations, and cardiovascular collapse, causing death within minutes. Patients exposed to hydrogen cyanide can survive with supportive care and rapid administration of specific antidotes. Decontamination Area

Cyanide poisoning is poisoning that results from exposure to any of a number of forms of cyanide. [4] Early symptoms include headache, dizziness, fast heart rate, shortness of breath, and vomiting. [2] This phase may then be followed by seizures, slow heart rate, low blood pressure, loss of consciousness, and cardiac arrest. [2]

Hydrogen cyanide (HCN) is a colorless, rapidly acting, highly poisonous gas or liquid that has an odor of bitter almonds. Most HCN is used as an intermediate at the site of production. Major uses include the manufacture of nylons, plastics, and fumigants.

Formonitrile, Hydrocyanic acid, Prussic acid Colorless or pale-blue liquid or gas (above 78°F) with a bitter, almond-like odor. [Note: Often used as a 96% solution in water.]

2021年1月1日 · Hydrogen cyanide (HCN) is a colorless or pale blue (hydrocyanic acid) extremely volatile liquid that is a potential threat to life at room temperature. The odor of HCN has a faint resemblance to bitter almonds.

2023年9月12日 · In patients with acute poisoning from hydrogen cyanide (HCN) gas or soluble salts, the principal acute care concerns are hemodynamic instability and cerebral edema.

Hydrogen cyanide is very volatile, producing potentially lethal concentrations at room temperature. The vapor is flammable and potentially explosive. Hydrogen cyanide has a faint, bitter almond odor and a bitter, burning taste. It is soluble in water and is …

2024年8月14日 · Hydrogen cyanide is highly toxic, with rapid onset of symptoms noted following acute exposure. Symptoms may occur within seconds following inhalation and minutes following ingestion or dermal...
