[Chemical Knowledge]：Specification for storage and transportation of toluene diisocyanate

Toluene diisocyanate (TDI) is an important chemical raw material, widely used in polyurethane foam, coatings, elastomers, adhesives and other fields. However, TDI is toxic and irritant and poses potential hazards to human health and the environment. Therefore, during the storage and transportation of TDI, the relevant safety regulations must be strictly observed to ensure the safety of personnel and the environment.

This article will detail the safe storage and transportation specifications for toluene diisocyanate.

1. safety storage specification

1. Storage facility requirements
TDI should be stored in a dry, cool, well-ventilated special warehouse, away from fire, heat and direct sunlight. The warehouse floor should be flat, non-slip, and with anti-leakage measures. The storage facilities shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment.
2. Storage container requirements
TDI should be stored in a special container, and the container should have good sealing performance and corrosion resistance. Storage containers should be inspected and maintained regularly to ensure that they are in good condition.
3. Storage limit requirements The storage quantity of
TDI shall be determined according to the production scale and safety management level of the enterprise, and shall not exceed the prescribed storage limit. At the same time, a strict inventory management system should be established to ensure that the storage and use of TDI meet the requirements of relevant regulations and standards.
4. Storage personnel management
TDI storage facilities should be equipped with professional management and operation personnel, after relevant training and obtain the corresponding qualification certificate. Storage personnel should conduct regular physical examinations to ensure that their physical health is in line with job requirements.

2. Safety Transportation Specification

1. Transportation vehicle requirements
TDI should be transported by a special tank truck, and the vehicle should have good sealing performance and corrosion resistance. Transportation vehicles shall be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment, and shall be regularly maintained and maintained to ensure safety during transportation.
2. Transport personnel require that transport personnel
TDI should undergo relevant training and obtain corresponding qualification certificates, and have safety awareness and operation skills for the transportation of hazardous chemicals. Transport personnel should undergo regular physical examinations to ensure that their physical health meets the requirements of the job.
3. Transportation route planning
TDI transportation routes should be reasonably planned to avoid densely populated areas and sensitive environmental areas. Relevant road transport regulations and standards should be followed during transportation to ensure transportation safety.
4. Transport identification and packaging requirements
TDI transport packaging should have obvious hazard identification and warning signs, indicating the name of the substance, danger and emergency measures and other information. The packaging shall meet the requirements of relevant regulations and standards, and have sufficient strength and sealing performance.
Emergency Treatment Measures for
3.

During the storage and transportation of TDI, in case of leakage, fire and other accidents, the following emergency treatment measures shall be taken:

1. Immediately start the emergency plan and organize professionals to deal with it;
2. Cut off the power supply and fire source in the accident area to prevent the accident from expanding;
3. Use special equipment to recycle the leaked materials to avoid environmental pollution;
4. In case of fire, foam, dry powder and other fire-fighting equipment shall be used to put out the fire;
5. Report the accident to the superior competent department in time and cooperate with relevant departments to investigate and deal with it.

In conclusion, safe storage and transportation regulations for toluene diisocyanate are essential to ensure the safety of personnel and the environment. Enterprises should establish and improve the relevant management system and operating procedures, strengthen the safety training and education of employees, and ensure that the storage and transportation process of TDI meets the requirements of relevant regulations and standards. At the same time, we should strengthen the formulation and exercise of emergency plans, improve the ability to deal with emergencies, and ensure the safety of production and social stability of enterprises.
