What are the fireproof technical conditions of special vehicles for flammable and explosive materials?

It may be that people often see vehicles with riot signs when they are driving at high speeds. Xiao Bian always feels safe when I drive this type of vehicle. In fact, this is only my psychological problem, because the flammable and explosive special vehicles are very safe, have reached the corresponding fire protection technical conditions and requirements before transport, otherwise it will not be on the road transportation. The following will introduce to you the specific requirements.

The most common types of flammable and explosive vehicles are tankers and tankers.

Automobile tank trucks mainly transport bulk oil, and its construction is relatively simple. The tank is made of 3 mm thick steel plate. The oil port should be installed at the front of the tank, and there should be a guide pipe through to the bottom of the tank. The manhole should be located at the middle of the tank. The bottom of the tank should have a drain valve, and the oil discharge valve should be equipped with an escalator. Many tank trucks now have safety equipment that protects against heat, heat, and inert gases. In the case of particularly low flashes of fuel for transport, inert gas protection devices should be used. Tanks should also be equipped with anti-wave plates to reduce the impact of oil on the vehicle when the shock. The anti-wave plate must be perforated and galvanized, and two are installed to divide the tank into three compartments that can communicate with each other to eliminate electrostatic accumulation in the tank. In addition, the tanker must be equipped with more than two dry powder fire extinguishers for emergency needs.

Automobile tankers are more complex in construction than tankers. Tanks should be equipped with mounting devices such as safety valves and overflow valves. The safety valve shall be built-in full-open type, and the height of the installation shall be such that the height of the exposed outer tank shall not exceed 150 mm and shall be protected. Tankers should also be equipped with anti-wave partitions on the tank. When the unloading pump is installed on the tanker, the pump shaft is connected with the main shaft of the automobile engine through the transmission mechanism, and the pump is driven by the automobile engine. In the valve box there are pressure gauges, thermometers, and liquid and gas tubes and their valves. Emergency shut-off valves should be installed at the outlet of the liquid and gas pipes. In addition, on the frame of the rear part of the car tanker, a buffer device not connected to the tank shall be installed. The horizontal distance from the rear end of the tank shall not be less than 100 mm. The width of the rear bumper may be Slightly less than the width of the entire vehicle, but not less than the outside diameter of the tank. The anti-static grounding chain for tank trucks is connected at the upper end to tanks and pipes, and the lower end is free to hang down to contact with the ground. An explosion-proof electrical device shall be used on the tank car and at least two dry powder fire extinguishers shall be provided.

Most of the requirements for tank tanks are silver-gray, and there must be no fireworks on the sides of the tank. The color requirements for the remaining exposed parts of the tank are: safety valve—red; gas phase pipe—red; valve—silver gray; liquid phase pipe—silver gray; Checking the installation equipment on the tank car regularly, especially the pressure gauge, must be verified.

After reading the above introduction, I believe that everyone is not very scared about flammable and explosive materials. In fact, as long as these fireproof technical conditions are met, it is still very safe.
