Which hazard class is represented by a placard reading nonflammable gas?

• A. Nonflammable gas
• B. Corrosives
• C. Flammable liquids/combustibles
• D. Toxic inhalation hazards

Answer: (A)

Hazard placards label the type of danger and, for gases, indicate whether the gas is flammable, nonflammable, or toxic. A placard that reads nonflammable gas identifies a gas that cannot burn, which places it in Class 2, specifically the nonflammable gas division. This is distinct from corrosives (Class 8), flammable liquids (Class 3), or toxic inhalation hazards (Class 6). So the reading on the placard directly points to the gas hazard in Class 2.
