Thousands of dangerous goods, according to their dangerous nature, transportation and public security fire department regulations are divided into 10 categories, namely, explosives, oxidants, compressed gases and liquefied gases, spontaneous combustion items, water burning items, flammable liquids, easy Burn solids, poisonous goods, corrosive articles, radioactive articles, etc. Some articles have more than two dangerous properties at the same time.
Toxic goods should be clearly marked with toxic signs. The main measure of anti-virus is tight packaging and airtightness. For example, potassium dichromate (red cesium potassium) and sodium dichromate <sodium erythrosene>, with red transparent crystal, toxic, application of solid barrel packaging, barrel mouth should be tight, the thickness of the iron plate can not be less than 1.2 mm . For products such as organic pesticides, asphalt sacks should be installed and the seams tightly sealed. If it is packaged in plastic bags or asphalt paper bags, the outside should be packed with sacks or cloth bags. The zinc phosphide used as a rodenticide is highly toxic. After the plastic bag is sealed tightly, it is packed in a wooden box. The box is insulated with two layers of kraft paper, moisture-proof paper or plastic film liner.
For corrosive goods, pay attention to chemical changes in the material of the goods and packaging containers. Metal-type packaging containers should be painted on the container walls to prevent corrosive products from corroding the containers. For example, the inner wall of an iron drum for packaging synthetic fatty acids is coated with an acid-resistant protective layer to prevent the iron barrel from being corroded by the commodity, and the quality of the product is also degenerated accordingly. Another example is hydrofluoric acid, which is an inorganic acid corrosion product, which is highly toxic and can corrode glass. It cannot be used as a packaging container for glass bottles. It should be packed in a metal bucket or a plastic bucket, but it is then loaded into a wooden box. Formic acid is volatile and its gas is corrosive. It should be installed in a good acid-resistant altar, glass bottle or plastic bucket, sealed tightly, and then put into a strong wooden box or metal drum.
The yellow phosphorus and other easily combustible goods should be packed in iron drums with a wall thickness of not less than 1 mm. The inner wall of the drum should be coated with an acid-resistant protective layer to hold the water in the barrel and allow the surface to be submerged in goods. The net weight per barrel does not exceed 50 kg. Another example is the water bow [from the burning of items such as calcium carbide, which breaks down when exposed to water and produces flammable acetylene gas, which is packaged in a sturdy iron drum and filled with nitrogen. If the barrel is not filled with nitrogen gas, the deflation piston should be installed.
For flammable and explosive goods, such as products with strong oxidizing properties, trace impurities or products that explode due to rapid decomposition due to heat. Anti-explosion packaging is an effective method is to use plastic barrels, and then plastic drums into iron drums or wooden boxes, each net weight does not exceed 50 kilograms, and should be automatically deflated safety valve, when the barrel reaches a certain gas pressure When it is automatically deflated.
