Which division is designated for toxic gases?

• A. Gas Division 2.1
• B. Gas Division 2.3
• C. Explosives Division 1.3
• D. Flammable Solids Division 4.1

Answer: (B)

Toxic gases are categorized separately within the gas class to highlight the inhalation and acute/chronic health hazards they pose, even if they aren’t flammable. The designation for toxic gases is Class 2, Division 2.3. This division specifically identifies gases that are poisonous or toxic, requiring protective measures to prevent exposure. Why this is the best choice: it directly matches the hazard type being tested—toxicity of the gas—regardless of flammability. The other options don’t fit because: 2.1 covers flammable gases (fire/explosion hazard), 1.3 falls under Explosives (not a gas), and 4.1 covers flammable solids (not a gas).
