How to pack the hottest dangerous goods

  • Detail

How to package dangerous goods there are thousands of kinds of dangerous goods. According to their dangerous nature, the transportation and public security fire department stipulates that they are divided into ten categories, namely, explosive substances, oxidants, compressed and liquefied gases, spontaneous combustion substances, substances that burn in water, flammable liquids, flammable solids, toxic substances, corrosive substances, radioactive substances, etc. some substances have more than two kinds of dangerous properties at the same time

the package of toxic goods should be clearly marked with toxic signs. The main measure of anti-virus is that the package is tight and airtight. For example, potassium dichromate (potassium jarosite) and sodium dichromate sodium jarosite =, which are red with transparent crystals and toxic, should be packed in a solid barrel, the barrel mouth should be tight, and the thickness of the iron plate used to make the barrel should not be less than 1.2 mm

commodities such as organic pesticides should be put into asphalt gunny bags with tight seams. If it is packed in plastic bags or asphalt paper bags, it should be packed in gunny bags or cloth bags. Zinc phosphide, which is used as a rodenticide, is highly toxic. It should be tightly sealed in plastic bags and then put into wooden boxes. The boxes are padded with two layers of kraft paper, moisture-proof paper or plastic film to isolate them from the outside world

for corrosive goods, we should pay attention to chemical changes in the materials of goods and packaging containers. Metal packaging containers should be painted on the container wall to prevent the corrosion of corrosive goods to the container. For example, the inner wall of the iron bucket that packs synthetic fatty acids should be coated with acid resistant protection. In order to replace the elimination method of pathological changes: replace the oil glass with suitable viscosity and treat the falling off of the visual film, people use a variety of substitutes, such as air, normal saline, aqueous humor of human eyes, silicone oil, sodium hyaluronate, collagen, heterogeneous glass, etc., to fill the glass, but the treatment effect is not satisfactory, so as to prevent the iron bucket from being corroded by commodities, As a result, the goods also deteriorate

for another example, hydrofluoric acid is an inorganic acid corrosive substance, which is highly toxic and can corrode glass. Glass bottles cannot be used as packaging containers, but should be put into metal barrels or plastic barrels, and then put into wooden cases. Formic acid is volatile and its gas is corrosive. It should be put into a good acid resistant jar, glass bottle or plastic bucket, sealed tightly, and then put into a solid wooden box or metal bucket

for the packaging of yellow phosphorus and other goods prone to spontaneous combustion, it is advisable to put them into an iron bucket with a wall thickness of not less than 1 mm. The inner wall of the bucket must be coated with an acid resistant protective layer. The bucket is filled with water, and the water surface is immersed in the goods. The bucket mouth is tightly closed, and the net weight of the barrel is not more than 50 kg. Another example is the water bow [inflammable items such as calcium carbide will decompose and produce flammable acetylene gas when encountering water. They should be packed in solid iron drums and filled with nitrogen. If the barrels are not filled with nitrogen, vent pistons should be installed.

for inflammable and explosive goods, such as those with strong oxidation, they will decompose rapidly when encountering trace impurities or products that cause explosion when heated. The effective method of explosion proof packaging is to use plastic drums for packaging, and then put the plastic drums Put it into an iron bucket or wooden box, each with a net weight of no more than 50 kg, and there should be a safety valve for automatic deflation. When the characteristics of the sample are compared in the bucket and through the superposition of curves to reach a certain gas pressure, it can automatically deflate
