Chemical transportation: six notes

the author 2. Paint and putty are not strong enough to be engaged in the transportation of petrochemical products for more than 20 years, and more than 200000 ton kilometers of chemicals such as cyclohexanone, toluene, styrene, epichlorohydrin are safely transported. We are well aware that petrochemical products are flammable, explosive and easy to pollute. Once they are caused by accident or leakage, it will be very dangerous, and the disposal and recycling is also extremely difficult. Therefore, the transportation of petrochemical products must not be taken lightly. The author summarizes six precautions

to be engaged in the transportation of dangerous goods, you must first become a half "expert" driver, learn some chemical knowledge, and understand the physical and chemical properties of the chemicals that are often carried. Before shipment, ask the business department about the physical and chemical properties of the goods and precautions, such as the mold temperature should be 50 (6) 0 ℃, the specific gravity, flash point, toxicity, expansion coefficient of the product, etc. For example, epichlorohydrin transported in barrels has a large expansion coefficient and is flammable. When filling, new barrels must be used, and the barrels must be full without space. In summer, install a shed pole and a canopy on the car, and keep it ventilated and protected from light, especially from direct sunlight; And apply to relevant departments for dangerous goods transportation certificates, hang small yellow flags, and write the words "dangerous goods" on them for people to identify. In addition, you should also bring a few bucket end sealing rings, one or two wet gunny bags, a small amount of sand, as well as special wrenches, dry powder fire extinguishers, etc. to meet the urgent need

the process of loading goods to the site for dangerous goods transportation is actually the process of testing the driver's heart, and we should be careful from the beginning. The loading of barreled dangerous goods seems simple, but in fact it is very exquisite. The loading should be uniform and balanced; All kinds of dangerous chemicals cannot be mixed, so as to avoid chemical reaction after leakage. One vehicle and one cargo should be achieved; There should be no gap between barrels, and the gap should be filled with waste cardboard or woven bags; The exhaust pipe shall be equipped with a flame arrester; The carriage is made of iron plate, and a layer of straw mat or reed mat should be paved to avoid sliding during driving; Then use ropes to bind the goods as a whole and fix them to ensure that the loading is firm

driving at medium speed, carefully driving and transporting dangerous goods, which is heavier than Mount Tai. Choose drivers who are mild tempered, skilled and non-smoking. Driving should be "courteous and three first", and take the initiative to avoid all kinds of vehicles. Avoid potholes, do not drive hero cars, angry cars, so that the vehicle moves forward smoothly. Try not to use the emergency brake during driving, so as to maintain the stability of the goods. It is worth reminding that no matter what kind of chemical products are transported, they should be covered with rain cloth to prevent cigarette butts from falling during the traffic intersection

the hidden danger of accidents in the transportation of dangerous goods starts from leakage. Due to the bumping and vibration of vehicles during the driving, it is often easy to cause package damage, and the damage is often concentrated in three "points":/p>

1. The barrel cover is not tightened or the sealing ring is ineffective

2. the weld of the iron barrel and the barrel reinforcement are damaged due to friction

3. Caused by displacement of barrel bottom during driving. First of all, there must be a willingness to change
