Arsine Gas Detection and Monitoring

Arsine, also known as arsenic hydride or AsH3, is a colorless, flammable, super toxic gas with a mild garlic odor at higher doses; and is odorless at lower levels. This super toxic gas is formed when arsenic comes in contact with an acid.

Arsine vapor is heavier than air, making it more likely to settle in low-lying areas. It is one of the most dangerous gases and is commonly found during hydrocarbon extraction and treatment operations. This super toxic gas is also present in industrial gases, hydrocarbon feedstocks, fuels and natural gas.

include chemical waste facilities, battery production facilities, the semiconductor and metals refining industries, and various manufacturing facilities, such as battery and firearm manufacturing.

The most common route of exposure to arsine is the inhalation of the toxic gas after it is released into the air. After it enters the bloodstream, it damages the red blood cells and can lead to signs and symptoms of hemolytic anemia as a direct result of this damage. However, the extent of risk depends on exposure levels and lengths.

Those exposed to low levels of arsine may experience mild symptoms, including confusion, drowsiness, fatigue, headache, nausea, shortness of breath, weakness, yellow skin and eyes, and muscle cramps. Exposure to large doses may result in more serious health effects, such as convulsions, loss of consciousness, paralysis, and respiratory compromise.

The presence of arsine in refineries and gasification processes represents a critical control point for the health and safety of personnel and the environment. Therefore, the monitoring of this substance at hazardous locations is essential. Utilizing an electrochemical sensor, our 6000, 6900 and 6940 series products can quickly and accurately detect arsine within diverse industries and applications.
