The packaging requirements for dangerous goods shall comply with the provisions of national laws, administrative regulations and rules, as well as the requirements of national standards and industry standards. Ships transporting dangerous goods and the containers they carry shall be produced in accordance with the national ship inspection standards, and approved by the maritime administrative agency. The certified ship inspection agency can only be put into use after passing the inspection. What are the packaging requirements of Changshu dangerous goods?
1. The packaging of toxic commodities should be clearly marked with toxic signs.
The main measures of anti-virus are tight packaging, airtight. For example, potassium dichromate (potassium red alum) and sodium dichromate, sodium red vanadium = red with transparent crystals, toxic, and should be packed firmly with barrels. Commodities such as organic pesticides should be packed into asphalt sacks with tight seams. If it is packed in plastic bags or asphalt paper bags, the outside should be packed in sacks or cloth bags. Zinc phosphide, which is used as rodenticide, is highly toxic. It should be tightly sealed in a plastic bag and then packed in a wooden box. The box is lined with two layers of kraft paper, moisture-proof paper or plastic film to isolate it from the outside world.
2. For corrosive commodities, pay attention to chemical changes in the materials of commodities and packaging containers.
For metal packaging containers, paint should be applied to the walls of the containers to prevent corrosion of the containers by corrosive commodities. For example, the inner wall of the iron barrel for packaging synthetic fatty acid should be coated with an acid-resistant protective layer to prevent the iron barrel from being corroded by the commodity, so that the commodity will also deteriorate. Another example is hydrofluoric acid, which is an inorganic acid corrosive item, highly toxic, and can corrode glass. Glass bottles cannot be used as packaging containers. It should be packed into metal barrels or plastic barrels, and then packed into wooden boxes. Formic acid is volatile and its gas is corrosive, so it should be put in a good acid-resistant jar, glass bottle or plastic barrel, tightly sealed, and then put in a solid wooden box or metal barrel.
3. For the packaging of flammable commodities such as yellow phosphorus, it should be put into an iron barrel with a wall thickness of not less than 1 mm, the inner wall of the barrel should be coated with an acid-resistant protective layer, and the barrel should be filled with water, and the water surface should be immersed in the commodities. Tightly sealed, the net weight of each barrel does not exceed 50 kg. Another example is the items that burn through water, such as calcium carbide, which decomposes and produces flammable acetylene gas when exposed to water. It should be packed in a sturdy iron barrel and filled with nitrogen. If the barrel is not filled with nitrogen, a deflation piston should be installed.
4. For flammable and explosive products, such as products with strong oxidizing properties, products that are rapidly decomposed and exploded when encountering MSI impurities or heating. The effective method of explosion-proof packaging is to use plastic barrels, and then put the plastic barrels into iron barrels or wooden boxes. , it can automatically deflate.
