🔍 Key Concepts

• IMDG Code class numbers vs. hazard names • Relationship between oxidizers, peroxides, and combustion • How corrosives, explosives, and radioactive materials are numbered in the IMDG classes

💭 Think About

• Think about which type of substance can intensify a fire without necessarily being flammable itself. • Recall which IMDG class number is used for explosives and compare that with class 5. • Ask yourself: in training materials, which class number is typically paired with the phrase “oxidizing”?

✅ Before You Answer

• Verify which IMDG class covers explosives and make sure it is not class 5. • Confirm whether corrosive substances are grouped under a different IMDG class number. • Check that radioactive material has its own distinct class number separate from oxidizers and peroxides.
