[Chemical Knowledge]：Specification for storage and transportation of glycerol

Read： 1021 Time：13months ago Source：Transform the World with Simplicity

Glycerol (Glycerol) is a common chemical raw material, widely used in food, medicine, cosmetics and other fields. Due to its hygroscopicity and flammability, certain safety regulations need to be observed during storage and transportation. This article will detail the safety storage and transportation specifications of glycerol.

1. the properties and hazards of glycerol

glycerol is a colorless, transparent, viscous liquid with a sweet taste and hygroscopicity. It is non-toxic to the human body, but excessive intake can cause diarrhea and dehydration. Glycerol has a high flash point and does not belong to flammable liquids, but it has a wide range of flammability and is exposed to open flames, high heat or oxidants, causing the risk of combustion and explosion.

2. glycerol storage specification

1. The storage place should choose a cool, ventilated and dry place, away from fire and heat sources.
2. The storage container should be made of stainless steel or plastic products with good sealing performance, and avoid the use of iron containers to avoid chemical reactions.
3. During storage, the tightness of the container and the quality of glycerol should be checked regularly to ensure that there is no leakage or deterioration.
4. The storage site shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment to deal with emergencies.

3. glycerol transport specification

1. before transport should check whether the packaging of glycerol intact, such as damage should be handled or replaced in a timely manner.
2. During transportation, it should be loaded and unloaded lightly to avoid severe vibration and collision and prevent package damage.
3. Glycerol should be stored and transported separately from oxidants, acids and edible chemicals, and mixed storage and transportation should not be allowed.
4. Transport vehicles shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment to deal with emergencies.

4. safety operation precautions

1. Operators should be professionally trained to understand the nature of glycerol and safe operation procedures.
2. Before operation, check the tightness of equipment and containers to ensure that there is no leakage.
3. During operation, sparks and static electricity should be avoided to avoid combustion and explosion.
4. If any abnormal situation is found, stop the operation immediately, take corresponding emergency measures, and report to the superior in time.

5. leakage emergency treatment

1. In case of glycerol leakage, the leakage source should be cut off immediately, and the residual liquid should be absorbed by sand, dry lime or soda ash.
2. When there is a large amount of leakage, a dam or a pit shall be constructed to accommodate it and be transferred to the tank car or special collector by pump.
3. Recycle or transport to the waste treatment site for disposal, avoid discharge into the sewer or random dumping.

6. fire protection measures

1. When glycerol is on fire, foam, dry powder, carbon dioxide and sand can be used to extinguish the fire, and water is invalid.
2. When extinguishing fire, the container should be moved from the fire site to the open area as much as possible, and the water spray should be used to keep the fire site container cool until the end of the fire extinguishing.
3. Containers in a fire scene that have discolored or sound from the safety pressure relief device must be evacuated immediately.

summary: As a common chemical production raw material, the safety and storage and transportation specifications of glycerol are of great significance to ensure production safety and personnel health. In the process of storage and transportation, relevant specifications and safety operation precautions should be strictly observed, and corresponding fire-fighting equipment and leakage emergency treatment equipment should be equipped to ensure safe production and transportation.
