Read： 441 Time：12months ago Source：Transform the World with Simplicity

O-phenylenediamine (OPD) is a common raw material for chemical production, which is widely used in medicine, pesticide, dye and other fields. However, due to its toxicity and flammability, strict compliance with relevant regulations is required during storage and transportation to ensure the safety of personnel and the environment. This article will introduce the safety storage and transportation specifications of o-phenylenediamine.

1. safety storage specifications

1. Storage facility requirements
o-phenylenediamine should be stored in a dry, cool, well-ventilated special warehouse, avoiding direct sunlight and high temperature. The warehouse floor should be flat, non-slip, and equipped with anti-leakage facilities. The storage area shall be provided with obvious safety warning signs and equipped with corresponding fire fighting equipment.
2. Storage container requirements
o-phenylenediamine should be stored in a special container. The container should be well sealed, not easy to be damaged, and can withstand a certain pressure. The container shall be marked with the name of o-phenylenediamine, hazard grade, production date and other information.
3. Storage management requirements
the storage of o-phenylenediamine should establish a strict management system, including storage, out of storage, collection, return and other records. Fireworks should be prohibited in the storage area, and regular safety inspections and maintenance should be carried out.

2. safety transport specification

1. Transport vehicle requirements
o-phenylenediamine should be transported by special transport vehicles, which should have the functions of anti-leakage, anti-fire, anti-static, etc. Transport vehicles should be marked with the name of o-phenylenediamine, risk level, transport units and other information.
2. Transport packaging requirements
o-phenylenediamine transport packaging should meet the relevant standards, packaging should be tight, firm, not easy to damage. The package shall be marked with the name of o-phenylenediamine, hazard level, production date and other information, and shall be accompanied by a safety label and shipping instructions.
3. Transportation management requirements
the transportation of o-phenylenediamine should establish a strict management system, including transportation plan, route planning, emergency measures, etc. During transportation, traffic rules should be observed, speed should be kept stable, and operations such as sudden braking and sharp turns should be avoided. Transport personnel shall have appropriate professional knowledge and emergency handling capacity.

3. emergency treatment measures

During the storage and transportation of o-phenylenediamine, in case of leakage, fire and other accidents, the following emergency treatment measures should be taken:

1. Leakage treatment: in case of o-phenylenediamine leakage, the leakage source should be cut off immediately, and special absorption materials should be used to clean up the leakage. During the cleaning process, sparks and static electricity should be avoided to prevent fire or explosion accidents.
2. Fire treatment: If a fire occurs, call the police immediately and use fire extinguishers, fire extinguishers and other fire fighting equipment to extinguish the fire. Keep a safe distance during fire fighting to avoid casualties.
3. First aid for personnel: if any personnel comes into contact with o-phenylenediamine or has poisoning symptoms, they should be moved to a safe area immediately and corresponding first aid measures should be taken. If the situation is serious, should be promptly sent to the hospital for treatment.

In short, o-phenylenediamine, as a toxic and flammable raw material for the production of chemicals, needs to strictly comply with relevant regulations during storage and transportation to ensure the safety of personnel and the environment. At the same time, a sound emergency response mechanism should be established to deal with possible unexpected situations.
