What is the classification of Class 5 HazMats?

• A. Toxic Materials
• B. Oxidizers & Organic Peroxides
• C. Radioactive Materials
• D. Gases

Answer: (B)

Class 5 HazMat covers materials that drive or influence combustion by providing oxygen or by decomposing in a way that releases heat and oxygen. Oxidizers are substances that release oxygen to support or intensify a fire, making any accompanying fuel burn more vigorously and potentially causing a rapid spread. Organic peroxides are a specific subgroup within Class 5 that can decompose rapidly and violently, often releasing heat and gases and sometimes oxygen themselves, which creates serious explosion and fire risks. This combination is what sets Class 5 apart from other classes: toxic materials are Class 6, gases are Class 2, and radioactive materials are Class 7. Therefore, the classification of Class 5 HazMats is Oxidizers & Organic Peroxides.
