Hazardous liquid packaging equipment manufacturers: how to store hazardous chemicals?

Manufacturers of hazardous liquid sub-packaging equipment: anti-volatile.

1. Oil seal: Ammonia, concentrated hydrochloric acid, concentrated nitric acid and other volatile inorganic liquids. Drop 10 to 20 drops of mineral oil on the liquid surface to prevent volatilization (vegetable oil is not allowed).

2. Water seal: CS with 5mL water can be stored for a long time. Manufacturers of hazardous chemical safety cabinets say adding water to mercury prevents mercury vapor from entering the air. Put some sulphur powder on the side. Once lost, dust with sulphur powder to eliminate residue from chemical reactions.

3. Wax seals for hazardous chemical safety cabinets: volatile liquids lighter or more soluble than water such as ether, ethanol and formic acid, volatile solids such as naphthalene and iodine. Close the cork and wax the bottle. In addition to sealing the original bromine bottle with wax, the original bottle should also be placed in a plastic cylinder with activated carbon, and the cylinder mouth should be sealed with wax.

Hazardous liquid sub-packaging equipment manufacturers: Dangerous chemical safety cabinet moisture-proof

1. Nao should be sealed with wax to prevent water absorption, decomposition or explosion. Sodium hydroxide is easy to absorb water and deliquescence, so it should be sealed with wax. Ammonium nitrate and sodium sulfate are easy to absorb water, but cannot be poured out, resulting in the rupture of the reagent bottle. They should also be tightly sealed.

2. Calcium carbide, anhydrous copper sulfate, phosphorus pentoxide and silica gel are easy to absorb water and deteriorate, red phosphorus is easy to oxidize, and then absorb water to generate metaphosphoric acid. All of the above should be stored in the dryer.

3. Although concentrated sulfuric acid needs to be sealed to prevent water absorption, because it is commonly used, it should be placed in a ground bottle, and the ground stopper should also be original. Don't switch.

4. The lower layer should be covered with ash, the middle layer should be covered with slaked lime, and the upper layer should be covered with double-layer asphalt paper, so that medicines can be stored.

1. Appropriately add some CH3 to the paste.

2. Put some volatile drugs such as formaldehyde and cresol soap into the safety cabinet of hazardous chemicals. In the medicine "Indications" cabinet. Concentrated hydrochloric acid and concentrated ammonia can be stored alternately in cabinets with severe rat infestation. to protect other drugs.

The storage places that constitute a major source of danger and involve explosives, toxic and harmful gases, and the storage places of Class A and B flammable liquids and liquefied gases, especially the tank farms where oil products or chemicals are stored separately, shall be protected from fire, explosion, and poison. Lightning protection, anti-static, moisture-proof, sun-proof, ventilation and other safety facilities and special layout of emergency equipment, equipment and personnel. Strictly manage the entry and exit registration of the reservoir area. Transport vehicles shall be refilled and registered in the approved quantity. Storage site management personnel, transport vehicle drivers, escort personnel, loading and unloading personnel, etc. Should be certified.
