Divinyldimethylsilane, a vital chemical compound, finds extensive applications in various industries, from silicone rubber production to organic synthesis. As a supplier of Divinyldimethylsilane, I understand the importance of adhering to transportation regulations to ensure the safe and legal movement of this substance. In this blog post, I will delve into the transportation regulations for Divinyldimethylsilane, providing valuable insights for both suppliers and customers.
Physical and Chemical Properties of Divinyldimethylsilane
Before discussing the transportation regulations, it is essential to understand the physical and chemical properties of Divinyldimethylsilane. This compound is a colorless, flammable liquid with a molecular formula of C6H12Si. It has a boiling point of approximately 103°C and a density of 0.763 g/cm³ at 25°C. Divinyldimethylsilane is highly reactive and can react violently with oxidizing agents, acids, and bases. It is also sensitive to moisture and can hydrolyze in the presence of water, releasing flammable hydrogen gas.
Classification of Divinyldimethylsilane for Transportation
According to the United Nations (UN) Globally Harmonized System of Classification and Labelling of Chemicals (GHS), Divinyldimethylsilane is classified as a flammable liquid (Category 2). This classification is based on its flash point, which is below 23°C. Flammable liquids are substances that can ignite easily and burn rapidly when exposed to an ignition source. As a result, special precautions must be taken during transportation to prevent fires and explosions.
Packaging Requirements
The packaging of Divinyldimethylsilane must meet specific requirements to ensure its safe transportation. The packaging materials must be compatible with the chemical and capable of withstanding the physical and chemical stresses of transportation. For Divinyldimethylsilane, approved packaging options include steel drums, aluminum containers, and plastic bottles. These containers must be tightly sealed to prevent leakage and labeled with the appropriate hazard symbols and warnings.
In addition to the primary packaging, secondary packaging may be required to provide an extra layer of protection. Secondary packaging can include cardboard boxes or wooden crates that are designed to hold the primary containers securely. The secondary packaging must also be labeled with the necessary information, such as the product name, quantity, and hazard warnings.
Labeling and Marking
Proper labeling and marking of Divinyldimethylsilane containers are crucial for ensuring the safety of those handling and transporting the substance. The labels must include the following information:
- Product Name: Clearly state the name of the product, which is Divinyldimethylsilane.
- Hazard Symbols: Display the appropriate hazard symbols, such as the flammable liquid symbol, to indicate the potential risks associated with the product.
- Signal Word: Use the signal word "Danger" to indicate the high level of hazard.
- Hazard Statements: Provide detailed hazard statements that describe the specific risks of the product, such as "Highly flammable liquid and vapor."
- Precautionary Statements: Include precautionary statements that outline the measures to be taken to prevent accidents and minimize the risks, such as "Keep away from heat, sparks, and open flames."
- Emergency Contact Information: Provide the contact information of the manufacturer or supplier in case of an emergency.
In addition to the labels, the containers must also be marked with the UN number for Divinyldimethylsilane, which is UN 1993. The UN number is a unique identifier that is used to classify and track hazardous substances during transportation.
Documentation
When transporting Divinyldimethylsilane, several documents are required to ensure compliance with transportation regulations. These documents include:
- Bill of Lading: A bill of lading is a legal document that serves as a contract between the shipper and the carrier. It includes information about the product, such as the name, quantity, and destination, as well as the terms and conditions of the transportation.
- Safety Data Sheet (SDS): A Safety Data Sheet provides detailed information about the physical and chemical properties of Divinyldimethylsilane, as well as its hazards, handling procedures, and emergency response measures. The SDS must be provided to the carrier and any other parties involved in the transportation.
- Dangerous Goods Declaration: A Dangerous Goods Declaration is a document that declares the presence of hazardous substances in the shipment. It includes information about the classification, packaging, and labeling of the goods, as well as the emergency contact information.
Transportation Modes
Divinyldimethylsilane can be transported by various modes of transportation, including road, rail, air, and sea. However, each mode of transportation has its own specific regulations and requirements.
Road Transportation
When transporting Divinyldimethylsilane by road, the carrier must comply with the regulations of the country or region in which the transportation is taking place. These regulations may include requirements for vehicle safety, driver training, and emergency response procedures. The vehicle used for transportation must be equipped with appropriate safety features, such as fire extinguishers and spill containment equipment.
Rail Transportation
Rail transportation of Divinyldimethylsilane is subject to the regulations of the railway company and the relevant national or international authorities. The railcars used for transportation must be designed and maintained to ensure the safe movement of the substance. The carrier must also follow specific loading and unloading procedures to prevent spills and accidents.
Air Transportation
Air transportation of Divinyldimethylsilane is strictly regulated due to the high risks associated with transporting flammable liquids in the air. The International Air Transport Association (IATA) has established detailed regulations for the transportation of dangerous goods by air. These regulations include requirements for packaging, labeling, documentation, and handling procedures. Only approved airlines and freight forwarders are allowed to transport Divinyldimethylsilane by air.
Sea Transportation
Sea transportation of Divinyldimethylsilane is governed by the International Maritime Dangerous Goods (IMDG) Code. The IMDG Code provides guidelines for the safe transportation of dangerous goods by sea, including requirements for packaging, labeling, stowage, and handling. The vessels used for transportation must be designed and equipped to handle hazardous substances safely.
Emergency Response
In the event of an accident or spill during the transportation of Divinyldimethylsilane, it is essential to have an emergency response plan in place. The emergency response plan should include procedures for evacuating the area, containing the spill, and extinguishing any fires. The personnel involved in the transportation should be trained in emergency response procedures and equipped with the necessary safety equipment, such as fire extinguishers, personal protective equipment (PPE), and spill containment materials.
