Which of the following is an example of Division 4.1 hazards?

• A. Gasoline, Kerosene, Diesel, Methane
• B. Salt, Sugar, Water, Sand
• C. Matches, Straw, TNT, Sulfur
• D. TNT, Gunpowder, Nitroglycerin, Nitrocellulose

Answer: (C)

Division 4.1 hazards are flammable solids—solids that can ignite readily and burn quickly, often through friction, heat, or impact. Matches are a classic example because they ignite when struck, and sulfur is another well-known flammable solid that can burn in air. Straw is also a readily ignitable solid. In the given options, the set that includes matches and sulfur shows true Division 4.1 materials. TNT is an explosive and belongs to a different hazard class, not Division 4.1, so it doesn’t define Division 4.1. The other options point to flammable liquids or inert solids rather than flammable solids. Therefore, this option is the best illustration of Division 4.1 hazards because it contains recognized flammable solids (matches and sulfur) among its items.
