🔍 Key Concepts

• Relationship between hazard classes and proper shipping names/labels in 49 CFR (Hazardous Materials Regulations) • Differences between flammable solids, flammable liquids, and gases in hazard communication • Meaning of the term "dangerous when wet" and how it is classified

💭 Think About

• Ask yourself: Which option describes a material that is primarily solid and capable of easy ignition or intense burning under normal transport conditions? • Think about which choice refers to a physical state of matter (solid, liquid, gas) versus a special behavior when contacting water. • Consider which hazard phrase is typically associated with materials that emit flammable gas when they come into contact with water.

✅ Before You Answer

• Match Class 4.1 with the correct primary hazard description (not secondary hazards). • Eliminate any answers that clearly correspond to other hazard classes (e.g., gases or liquids). • Verify that the label name you choose correctly reflects a solid material’s main hazard, not its reaction with water or its being a gas.
