5.2
Organic peroxides and oxidizers fall under the Department of Transportation (DOT) Hazard Class 5. Organic peroxides are categorized as Division 5.2, while oxidizers are classified under Division 5.1. Both classes are recognized for their potential to cause fire and explosion hazards, necessitating careful handling and transportation.
Organic peroxides are classified under DOT Hazard Class 5.2 and oxidizers are classified under Hazard Class 5.1. Organic peroxides are substances that can release oxygen and initiate combustion, while oxidizers are substances that can react exothermically with other materials, often accelerating combustion.

Class 4 division 1 (more properly called Division 4.1) is for flammable solids.
There is no Class 3 Division 2; Class three has no subdivisions.
Fats are a class of organic compounds.
DOT Class 3 is for flammable liquids, but there is no subdivision of the class so there is no division 3 for this class.

Class 4 division 1 (more properly called Division 4.1) is for flammable solids.
Class 4 Division 1 (more properly called Division 4.1) is for flammable solids.
A material in Class 4 Division 3, more properly called Division 4.3, is a Dangerous When Wet material.
The most dangerous classes of dangerous goods are Class 1 (Explosives), Class 2 (Gases), Class 3 (Flammable Liquids), Class 4 (Flammable Solids), Class 5 (Oxidizing Substances and Organic Peroxides), Class 6 (Toxic and Infectious Substances), Class 7 (Radioactive Material), Class 8 (Corrosives), and Class 9 (Miscellaneous Dangerous Goods). Among these, Class 1 and Class 7 are often considered the most hazardous due to their potential for catastrophic incidents or long-term health risks. Proper handling, storage, and transportation protocols are essential to minimize the risks associated with these materials.
