Inhalation & Ingestion Health Hazards

INHALATION	Inhaled HF initially affects nose, throat, Eyes. Mucous membrane irritation, cough, choking. Airway obstruction. Lung Injury may be delayed 12 -36 hrs.
INGESTION	Intentional ingestion of large volume. ( Abdominal Pain , Vomiting ) Potential absence of Gastrointestinal Symptoms with dilute ingestion. Systemic poisoning may occurs within 1- 4 hrs. 20 to 30 ppm – A reflex breathing difficulty Above 25 ppm – irritation, burns, ulcerous lesions, and localized destruction of the tissues (necrosis) of the eyes, skin, and mucous membranes.

Hydrogen Cyanide HCN Monitoring 

Hydrogen Cyanide is a colorless gas ( At higher temperatures ). Hydrocyanic acid is a colorless or pale blue liquid, with bitter almond odor and bitter burning taste. Hydrogen cyanide is highly volatile and produces lethal concentrations at room temperature and the HCN vapor is flammable and potentially explosive. Its used as 96% aqueous solution and is soluble in water.

Hydrogen cyanide is a predominant industrial chemical and primarily used in the manufacturing of plastics, synthetic fibers like nylon, paints and other chemicals, ore-extraction, electroplating, dying, printing, photography, metal cleaning etc. HCN and other cyanide compounds are also being used as a fumigant to control pests.

Hydrogen Cyanide	HCN	Rotten eggs	5.6	40	0.93 Slightly  Lighter than air	630mmHg	27.03	13.6eV	0.58 ppm

Common Sources of hydrogen cyanide

Hydrogen cyanide is released from a several natural processes such as, by bacteria, fungi, volcanic activity etc. Other sources includes industrial processes, from combustion or from accidents involving HCN transport. Combustion processes produce hydrogen cyanide gas in the form of gas. Other sources of HCN emission includes building fires, cigarettes, vehicles exhausts and fires involving nitrogen-containing materials such as polyurethane foams.
