Question 1 of 27070

In accordance with U.S. regulations which of the following is the proper label name for a class 4.3 substance?

🔍 Key Concepts

• Hazard classes for flammable solids and related substances under U.S. regulations (49 CFR hazmat table) • The three divisions of Class 4: 4.1, 4.2, 4.3 and what each one represents • How the proper label name relates to the specific hazard (e.g., reacts with air vs. reacts with water)

💭 Think About

• Ask yourself: which of these hazards is specifically associated with substances that can become dangerous when they contact water, rather than just air or heat? • Recall which division number (4.1, 4.2, or 4.3) is tied to spontaneous combustion versus those that burn easily as solids. • Match each answer choice to the type of reaction: simple flammability, flammable solid, spontaneous combustion, or reaction with water producing flammable gases.

✅ Before You Answer

• Confirm from your hazmat classification chart what Class 4.3 is defined as, in words. • Verify which exact wording appears on the hazard label for this division (not just the general class heading). • Make sure you are not mixing up Class 4.1 (flammable solids) or 4.2 (spontaneously combustible) with 4.3.
