Arsine is classified as which hazard class?

• A. 2.3
• B. 2.1
• C. 2.2
• D. 3.1

Answer: (A)

Arsine is a toxic gas. Hazard Class 2 covers gases, and the divisions specify the type of gas: 2.1 is flammable gases, 2.2 is non-flammable, non-toxic gases, and 2.3 is toxic gases. Arsine is a gas at room temperature and is extremely toxic to humans if inhaled, with no distinctive flammability issues under normal conditions. It is not a liquid, so it doesn’t fit 3.1, which is for flammable liquids. Therefore, arsine falls under 2.3, toxic gases. This classification guides safety measures like leak detection, ventilation, respiratory protection, and avoidance of inhalation exposure.
