Is there anything we should pay attention to when storing chemical raw materials?

First of all, we must understand the characteristics of chemical raw materials, such as whether they are flammable and explosive, and whether they will react with what items. These are things we should pay attention to. After knowing this, We must first separate things that may react with each other and cannot put them together. This is very important. Then we must place some things that are afraid of light in a cool place, and secondly put some things that are afraid of water in a dry place to prevent the products from deteriorating.

In addition, you must be very careful when using chemical raw materials. In fact, many unnecessary accidents are often caused by carelessness. In addition, we did not have any problems when we placed it, but if we did not put it back in time after use, it would also cause a lot of trouble, because many problems often arise from carelessness. From this aspect Say, we really need to pay attention to these. It is best to put some user manuals of related products and raw materials in these places and formulate some usage specifications. And make some warning slogans, which can continue to keep us vigilant and alert, so as to reduce unnecessary troubles.

Chemical product storage requirements

1. Storage warehouse environment and placement requirements

1. Chemicals must be stored in dedicated warehouses, dedicated sites or dedicated storage tanks. Hazardous chemicals that are stored in quantities that constitute major hazard sources must be stored in dedicated warehouses or storage tanks. Store separately inside.

2. According to the types and characteristics of hazardous chemicals, corresponding monitoring, ventilation, sun protection, temperature regulation, fire prevention, explosion protection, pressure relief, virus prevention, disinfection, neutralization, moisture-proof, and anti-chemical systems should be set up in the warehouse. Lightning, anti-static, anti-corrosion, anti-leakage, protective dikes and other safety facilities shall be maintained and maintained in accordance with national standards and relevant regulations to ensure safety requirements. The storage area should be equipped with ventilation and alarm devices, and ensure that they are in normal use under any circumstances.

3 Special chemical warehouses should comply with national standards for safety and fire protection, and clear signs should be set up. The storage facilities of special warehouses for hazardous chemicals should be regularly monitored.

4 Items with mutual taboos and different fire extinguishing methods cannot be stored together. They must be stored in separate rooms and warehouses, and the name, nature and fire extinguishing method of the stored substances must be clearly marked in a conspicuous place.

5 Inventory chemicals should be classified and stacked for storage. The area of ??each stack should not be greater than 100m2, the distance between stacks should not be less than 1m, the distance between stacks and walls should not be less than 0.5m, and the distance between stacks and columns should not be less than 0.3m , the main channel width is not less than 2m.

6 Warehouses that store oxidants, flammable liquids, flammable solids and highly toxic items should have floors that are easy to flush and non-combustible materials. Warehouse floors that are required to prevent sparks must be made of non-flammable materials. Sparks ground.

2. Compressed gas and liquefied gas storage

1 The warehouse should be cool and ventilated, away from heat sources and fires, prevent sunlight exposure, and heat is strictly prohibited. Explosion-proof lighting should be used for lighting in the warehouse. No combustible materials should be piled around the warehouse.

2 Attention should be paid to the acceptance of steel cylinders when they are put into storage: the packaging appearance should have no obvious trauma, the accessories should be complete, the sealing should be tight, and there should be no air leakage. The packaging use period should be within the specified period of the pressure test, and no extension is allowed after the expiration date. The pressure must be retested.

3 Cylinders with mutually incompatible contents should be stored in separate warehouses. For example, acetylene bottles and oxygen cylinders must not be mixed in the same warehouse. Flammable gases must not be stored together with other types of chemical dangerous goods. The stored cylinders should be placed upright and neatly, protected and fixed with cabinet racks or fences, and passages should be left.

3. Storage of flammable liquids

1 Flammable liquids should be stored in a cool and ventilated warehouse, away from fire, heat sources, oxidants and oxidizing acids. For flammable liquids with a flash point lower than 23°C, the warehouse temperature generally does not exceed 30°C, and cooling-type refrigeration measures must be adopted for low-boiling-point varieties. Large amounts of storage (such as benzene, alcohol, gasoline, etc.) should be stored in storage tanks. The machinery must be explosion-proof and have a grounding device to conduct static electricity. Storage tanks can be left in the open air, but cooling measures should be taken when the temperature is above 30°C.

2 Special warehouse dumps shall not be mixed with other hazardous chemicals.

Four. Storage of wet and flammable items

1 Store strictly in the open air, the warehouse must be dry, and no water leakage or rain or snow can enter. Pay attention to the smooth flow of sewers and ensure that no water enters during heavy rains or floods.

2 The warehouse must be kept away from fire and heat sources, and items that emit acid mist such as hydrochloric acid and nitric acid must not be stored nearby.

3 The packaging must be tight and must not be damaged. If damaged, measures should be taken immediately.

4 It is not allowed to be mixed, stored or transported with other hazardous chemicals, especially acids, oxidants, water-containing substances and moist substances. Items that conflict with fire-fighting methods are not allowed to be stored in the same warehouse or transported in the same vehicle.

5. Storage of oxidants and organic oxides

1 Oxidants should be stored in a clean, cool, ventilated and dry warehouse away from fire and heat sources to prevent sun exposure and lighting facilities should be explosion-proof.

2 The warehouse must not leak water, and should prevent the intrusion of acid mist. It is strictly prohibited to mix and store with acids, flammable substances, organic substances, reducing agents, self-igniting items, and flammable items when exposed to moisture.

3 Different types of oxidants should be transported in appropriate warehouse categories according to their properties and fire-fighting methods. For example, organic peroxides must not be stored and transported with inorganic peroxides; nitrites, chlorites, and hypochlorites must not be stored and transported with other oxidants; peroxides should Special warehouse storage, special vehicle transportation.

4 The warehouse should be thoroughly cleaned before and after storage and before and after loading and unloading of transport vehicles. It is strictly forbidden to mix organic matter, flammable substances and other impurities.

6. Storage of Drugs

1 Drugs must be stored in a warehouse. They must not be stored in the open air. They should be kept away from open flames and heat sources. The warehouse should be well ventilated.

2 It is strictly prohibited to mix storage and transportation of drugs with food or food additives.

3. Drugs must not be stored or transported together with other types of items (including non-dangerous goods), and should be strictly separated from acids and oxidants.

4 If drugs are stored, you should first check whether the packaging container is complete and sealed. Any damaged packaging will not be stored.

5 It should be noted that different fire-fighting methods should be adopted according to the nature of the drugs.

Seven. Storage of corrosive products

The types of corrosive products are relatively complex and should be stored in different warehouses according to their different properties. Storage containers must be used reasonably according to different corrosive properties.
