How to Store Epichlorohydrin Safely

How to safely store epichlorohydrin: comprehensive storage considerations

Epichlorohydrin (Epichlorohydrin, ECH) is an important chemical raw material, widely used in the production of epoxy resins, surfactants and other chemicals. Because of its high flammability and corrosive properties, safe storage of epichlorohydrin is a critical part of industrial operations. How to store epichlorohydrin safely? This article will analyze in detail from multiple angles.

1. Epichlorohydrin storage environment requirements

The environmental requirements for the storage of epichlorohydrin are very strict, and the storage site should be kept away from fire, high temperature, strong acid and strong alkali. Because epichlorohydrin is extremely flammable, the storage area must be kept dry and well ventilated. The temperature in the warehouse should be controlled within the normal temperature range, usually should not exceed 30°C. The humidity in the storage area should be kept as low as possible to prevent the moisture from reacting with epichlorohydrin and causing corrosion or danger.

The storage place should be away from any equipment that may cause fire or explosion, such as heating devices, electrical equipment, etc. It is recommended to use non-sparking tools and equipment for operation.

2. Storage container selection and requirements

Another important factor in how to safely store epichlorohydrin is the choice of storage container. Epichlorohydrin should be stored in corrosion-resistant, well-sealed containers. In general, metal containers are not suitable for storing such chemicals because epichlorohydrin may react with certain metals. Materials that do not react with chemicals, such as plastic or glass, are recommend used, especially polyethylene (PE) or polypropylene (PP) containers.

The storage container must be kept sealed to avoid vapor leakage, which not only helps to maintain the quality of the epichlorohydrin, but also prevents the escape of harmful gases, causing harm to the environment and operating personnel. The storage container shall be clearly marked with the name of the substance, the danger and the relevant safety operation procedures.

3. Epichlorohydrin storage safety protection measures

When storing epichlorohydrin, in addition to ensuring proper containers and environment, it is necessary to provide appropriate safety protection equipment. For example, storage areas must be equipped with fire fighting equipment, including fire extinguishers, fire sprinklers and emergency sprinklers. Suitable fire extinguishing equipment (such as dry powder fire extinguisher, carbon dioxide fire extinguisher) shall be selected according to the fire risk of epichlorohydrin.

In order to prevent accidental leakage or accidents, storage areas should also be equipped with emergency leakage treatment equipment, such as adsorption materials and leakage cleaning tools. In the event of a leak, emergency response procedures should be initiated immediately to ensure that the leak is dealt with quickly and to avoid spread.

4. Epichlorohydrin transportation and handling precautions

During the transportation and handling of epichlorohydrin, in addition to selecting suitable containers, it should also be ensured that vibration, impact and drastic temperature changes are prevented during transportation. The means of transport shall be equipped with fire and explosion-proof measures, and avoid transporting with inflammable and explosive articles. When handling epichlorohydrin, operators should wear necessary protective equipment such as protective clothing, gloves and goggles to prevent contact with skin or eyes.

5. Regular inspection and inventory management

How to safely store epichlorohydrin also involves regular inspection and inventory management. The stored epichlorohydrin shall be inspected periodically to ensure the integrity and tightness of the container and to check that the storage environment meets safety requirements. Regularly check the integrity of safety facilities such as fire extinguishers and leakage treatment equipment to ensure that they can respond quickly in the event of an accident.

Inventory management is also critical, and epichlorohydrin should be managed on a first-in, first-out basis to avoid expiration or deterioration due to long-term storage. All storage records shall be recorded in detail for traceability and management.

Conclusion

The safe storage of epichlorohydrin is not only related to the selection of storage containers and environmental control, but also involves perfect safety protection measures and emergency plans. Only through strict operating procedures and management measures can we ensure the safety of epichlorohydrin during storage, prevent accidents, and protect the safety of employees and the environment. It is hoped that the analysis of this paper can help the industry to better understand how to safely store epichlorohydrin and ensure the safe and smooth progress of the production process.
