What are the three major categories of substances for tanker trucks?

Class III hazardous materials include flammable liquids such as diesel, gasoline, paint, acetone, kerosene, ethanol, and sulfur dioxide. Operating a hazardous material transport vehicle requires holding a 'Hazardous Materials Professional Qualification Certificate'. The following are the requirements for transport vehicles: 1. Box trucks for transporting gases: Box trucks transporting bottled compressed gases and liquefied gases must be equipped with ventilation devices and securing devices. 2. Special vehicles for transporting flammable and explosive materials: Special vehicles for transporting flammable and explosive materials must all be fitted with conductive rubber grounding straps that meet regulatory standards. 3. Vehicles for transporting horizontally placed bottled compressed gases: Special vehicles transporting horizontally placed bottled compressed gases and liquefied gases must have internal compartment widths that meet the length dimensions of the cylinders; otherwise, the vehicle must be replaced to meet transport requirements. 4. Vehicles for transporting oxides: Oxidizers and organic peroxides must be transported using temperature-controlled box-type special vehicles.
After driving for so many years, I've seen tanker trucks mainly transporting three categories of substances: petroleum products, corrosive chemical liquids, and liquefied gases. Starting with petroleum, fuels like gasoline and diesel are on the road every day, heading to gas stations. As for chemicals, they include industrial acids, alkalis, and solvents, which are quite dangerous—if they leak, they can corrode equipment. Common gas types include liquefied petroleum gas or compressed gas cylinders, which require high-pressure handling during storage. I must remind everyone that transporting these substances requires strict controls, and checking the tank's sealing is crucial. When I go on long-distance trips, I always carry an emergency toolkit to deal with potential leaks. Remember, safety comes first—if something goes wrong, call professional help immediately and don't try to handle it yourself. Keeping up with regular vehicle maintenance can reduce risks, which benefits both drivers and the public.
