Read： 1071 Time：12months ago Source：Transform the World with Simplicity

GBL(γ-Butyrolactone) is an important raw material for chemical production, which is widely used in medicine, pesticide, spice and other fields. However, GBL has certain toxicity and danger, so it is necessary to strictly abide by relevant regulations during storage and transportation to ensure safety. This paper will detail the safe storage and transportation specification of GBL.

1. the physical and chemical properties of GBL

GBL is a colorless transparent liquid with a special pungent odor. It is soluble in water, ethanol, ether and other organic solvents, but insoluble in petroleum ether. GBL has a boiling point of 205 ℃ and a flash point of 95 ℃, which is a flammable liquid. In addition, GBL is also corrosive and toxic, which is harmful to the human body.

2. GBL safety storage specification

1. Storage site requirements: GBL should be stored in a cool, dry, well-ventilated special warehouse, away from fire, heat and direct sunlight. Fire fighting equipment and leakage emergency treatment equipment shall be set in the warehouse.
2. Storage container requirements: GBL should be stored in special stainless steel or plastic containers, avoid the use of iron, aluminum and other metal containers to prevent corrosion. The container should be well sealed to prevent leakage.
3. Storage limit requirements: The storage capacity of GBL shall be strictly controlled and shall not exceed the specified limit. At the same time, it should be stored separately from oxidants, acids, alkalis and other items, and mixed storage is prohibited.
4. Safety management requirements: The warehouse shall be managed by a special person, and regular safety inspections and inspections shall be carried out, and abnormal situations shall be handled in time. Warehouse management personnel should be professionally trained to understand the nature of GBL and safe operating procedures.

3. GBL safety transport specification

1. Transport vehicle requirements: GBL should use a dedicated tank car or van for transport, the vehicle should have good sealing performance and fire, explosion, anti-static and other safety facilities.
2. Requirements for transportation personnel: transportation personnel should be professionally trained to understand the nature of GBL and safe operation procedures, and have the ability to respond to emergencies.
3. Transportation route requirements: the transportation route should choose safe roads and avoid passing through densely populated areas and sensitive areas. During transportation, the vehicle speed should be kept stable and operations such as sudden braking and sharp turns should be avoided.
4. Transport packaging requirements: GBL packaging should comply with relevant regulations, packaging containers should be firm, sealed to prevent leakage. In the process of transportation, the integrity of the packaging container should be checked regularly, and the damage should be dealt with in time.

4. GBL leakage emergency treatment specification

1. Leakage treatment: in case of GBL leakage, emergency treatment plan should be started immediately, and effective measures should be taken to prevent the leakage from spreading. The leakage can be covered and collected with adsorption materials such as sand and dry lime, and then sent to the designated place for safe disposal.
2. Personnel protection: when dealing with GBL leakage, personal protective equipment such as protective clothing, gloves and goggles should be worn to avoid direct contact with the leakage.
3. Environmental monitoring: In the process of leakage treatment, the surrounding environment should be monitored in real time to ensure that environmental indicators such as air quality and groundwater meet relevant standards.

In short, GBL, as an important raw material for chemical production, needs to strictly abide by relevant regulations during storage and transportation to ensure safety. By strengthening safety management, improving safety facilities, improving personnel quality and other measures, we can effectively reduce the risk of GBL leakage and safety accidents, and ensure the safety of people's lives and property.
