Hazmat division 2.3 hazards are described as what?

• A. Cryogenic Hazards
• B. Inhalation Hazards
• C. Toxic Hazards
• D. Corrosive Hazards

Answer: (B)

Division 2.3 hazards describe toxic gases where the main danger comes from inhalation. These gases are part of the Class 2 group (gases), and the defining risk is that breathing them can cause serious health effects or death, so protection focuses on preventing inhalation exposure—using proper respirators, detecting leakage, and ensuring good ventilation. Examples you might encounter include chlorine or phosgene, which are harmful when inhaled.

Cryogenic hazards relate to extremely cold temperatures, not primarily to inhalation toxicity. A general “toxic hazards” label is broader and doesn’t specifically emphasize the inhalation route that defines division 2.3. Corrosive hazards involve damage to skin, eyes, or materials, and aren’t the specific inhalation-focused descriptor for this division.
