Which division corresponds to toxic gases?

Which division corresponds to toxic gases?

• A. Explosives Division 1.5
• B. Gas Division 2.3
• C. Gas Division 2.1
• D. Flammable Solids Division 4.1

Answer: (B)

Gases are categorized under Class 2, and within that class the divisions separate the specific hazards: flammable gases, non-flammable/non-toxic gases, and toxic gases. The division that covers toxic gases is the one that identifies gases hazardous to health, i.e., toxic gases. That makes it the correct match for a question asking which division corresponds to toxic gases. The other options point to different hazards: explosives belong to the explosives class, flammable solids are a solid hazard in a separate class, and one of the gas divisions is for flammable gases. So recognizing that toxic gases are classified under the division for toxic gas hazards explains why this choice is the right one.
