Read： 435 Time：20months ago Source：Transform the World with Simplicity

In the field of chemical production raw materials, PLA (polylactic acid) is a biodegradable plastic, because of its environmental protection and sustainability, is widely used in packaging, fiber, 3D printing and other fields. However, PLA also has certain safety risks during storage and transportation, so it is necessary to comply with the corresponding regulations.

1. the safety
of PLA
As a biodegradable plastic, PLA itself is non-toxic and harmless, but under certain conditions such as high temperature and high pressure, it may decompose to produce acidic substances, which will have a certain impact on equipment and the environment. In addition, PLA may also produce some volatile gases during processing, which requires attention to ventilation and protective measures.

2. PLA storage specifications

1. Storage environment: PLA should be stored in a dry, cool, well-ventilated indoor environment, avoid direct sunlight and high temperature.

2. Storage container: A container with good sealing and corrosion resistance should be selected for storage to avoid quality changes due to contact between PLA and air, moisture, etc.

3. Storage period: PLA should have a certain storage period, and expired PLA should be inspected and tested to ensure its quality and safety in use.

3. PLA's transportation specifications

1. Transportation vehicles: Transportation vehicles that meet relevant regulations should be selected to ensure the stability and safety of the vehicles during transportation.

2. Transport packaging: PLA should be properly packaged to avoid damage, leakage and other safety accidents during transportation.

3. Transportation route: A reasonable transportation route should be selected to avoid transportation in bad weather or bad road conditions.

4. Safety Operation Specification

1. Operators should receive relevant safety training to understand the nature and safety operation procedures of PLA.

2. During the operation, conditions such as high temperature and high pressure should be avoided to prevent PLA from decomposing to produce acidic substances.

3. In the process of processing, ventilation and protective measures should be strengthened to avoid the generation of volatile gases causing harm to operators and the environment.

5. emergency plan

During the storage and transportation of PLA, in order to deal with possible safety accidents, corresponding emergency plans should be formulated. The emergency plan should include the following aspects:

1. Organization setup: make clear the organization and division of responsibilities of emergency response, and ensure that the emergency response can be started quickly in case of emergency.

2. Communication: Establish an effective communication mechanism to ensure timely transmission of information and coordination of resources in emergency situations.

3. emergency materials reserve: reserve necessary emergency materials and equipment in advance to ensure that they can be put into use in time in case of emergency.

4. Emergency handling measures: According to the types of safety accidents that may occur, formulate corresponding emergency handling measures to ensure that the development of the situation can be quickly controlled in an emergency.

In short, in the field of chemical production raw materials, in order to ensure the safe storage and transportation of PLA, the corresponding specifications and safe operation requirements should be observed, and a complete emergency plan should be formulated to ensure that it can respond quickly in emergency situations. Guarantee the safety of personnel and property.
