Title: Safety Storage and Transportation Specification
of TDI in the Field of Chemical Production Raw Materials
1. Introduction

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 corrosive and may pose a hazard to humans and the environment. Therefore, in the field of chemical production raw materials, the safe storage and transportation of TDI is very important. This article will discuss the safety storage and transportation specifications of TDI to ensure the safety of production process and personnel.

2. the toxicity and harm of TDI

TDI is a toxic and harmful chemical substance, which has potential harm to human body and environment. Long-term exposure to TDI may cause irritation and damage to the respiratory system, skin and eyes, and even cause serious diseases such as allergic reactions and cancer. Therefore, during the production, storage and transportation of TDI, relevant safety regulations must be strictly observed to ensure the safety of personnel and the environment.

3. TDI safety storage specifications

1. Storage facilities 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 have fire prevention, explosion-proof, lightning protection and other safety measures.
2. Storage container requirements: TDI should be stored in a special stainless steel or plastic container, and ensure that the container is well sealed to prevent leakage. The container shall be marked with TDI name, concentration, production date and other information.
3. Storage management requirements: TDI storage should establish a strict management system, including warehousing registration, outbound records, inventory counting, etc. The storage area shall be provided with obvious safety warning signs, and equipped with corresponding fire-fighting equipment and emergency measures.

4. TDI safety transport specification

1. Transport vehicle requirements: TDI should use a dedicated tank car or van for transport, the vehicle should have fire prevention, explosion-proof, anti-leakage and other safety measures. The condition of the vehicle should be checked before transportation to ensure safety and reliability during transportation.
2. Transportation packaging requirements: The packaging of TDI should meet relevant standards, and the packaging container should be strong, sealed, and able to withstand vibration and impact during transportation. The package shall be marked with the name, concentration and danger of TDI.
3. Transportation management requirements: TDI transportation should comply with relevant laws, regulations and standards, and establish a sound transportation management system and operating procedures. During transportation, stable driving should be maintained to avoid severe vibration and collision to ensure transportation safety.

5. TDI safety storage and transportation precautions

1. In the TDI storage and transportation process, should be equipped with professional operators and management personnel to ensure that the safety measures are effectively implemented.
2. Regular safety inspections and assessments should be carried out to discover and resolve potential safety hazards in time to ensure that the storage and transportation of TDI is always in a safe and controllable state.
3. In response to emergencies, detailed emergency plans and measures shall be formulated to ensure personnel safety and environmental safety.

6. conclusion

TDI in the field of chemical production of raw materials in the field of safe storage and transportation is very important, need to strictly abide by the relevant safety norms and standards, to ensure the safety of personnel and the environment. By strengthening the construction and management of storage and transportation facilities, the training and management of operators, and the formulation and implementation of emergency plans, the safe storage and transportation of TDI can be effectively guaranteed.
