[Chemical Knowledge]：Specification for storage and transport of silicone DMC

Read： 1156 Time：20months ago Source：Transform the World with Simplicity

Silicone DMC has important application value in the field of chemical production raw materials, but its safe storage and transportation regulations are very important to ensure production safety and personnel health. This article will introduce in detail the physical property data, risk overview, first aid measures, fire protection measures, leakage emergency treatment, operation disposal and storage, contact control/personal protection, physical and chemical characteristics, stability and reactivity, toxicological data, ecological data, waste disposal and transportation information.

1. physical data

silicone DMC is a colorless and transparent liquid with a pungent odor. Its molecular formula is C5H12OSi and its molecular weight is 116.24. Silicone DMC is insoluble in water but miscible with a wide range of organic solvents.

2. risk overview

silicone DMC is a low toxic chemicals, but still has a certain degree of risk. Prolonged exposure or inhalation of silicone DMC may affect the nervous and respiratory systems of the human body. In addition, silicone DMC is also flammable and corrosive, so special care needs to be taken during storage and transportation.

3. first aid measures

such as personnel contact with silicone DMC, should immediately take off the contaminated clothing, rinse the skin with plenty of water. If the eyes come into contact with silicone DMC, immediately lift the eyelids and rinse with flowing water or normal saline. If there is inhalation, the patient should be moved to fresh air to keep the respiratory tract unobstructed.

4. fire protection measures

silicone DMC is flammable and should be kept away from open flames, high temperatures and oxidants. In case of fire, foam, dry powder, carbon dioxide and other fire extinguishers shall be used to extinguish the fire.
Emergency treatment of
5. leakage

If silicone DMC leakage occurs, the leakage source should be cut off quickly to prevent the leakage from entering the restricted space such as sewers and flood discharge ditches. Adsorption with inert absorbent materials such as sand, vermiculite, and then collected in a container for disposal.

6. operation, disposal and storage

should strictly abide by the operating procedures and wear protective equipment when handling and disposing of silicone DMC. The container for storing silicone DMC should be well sealed and stored in a cool and ventilated special warehouse, away from fire and heat sources.

7. contact control/personal protection

In the production process, the contact concentration and time of silicone DMC should be strictly controlled. Operators should wear protective gloves, protective glasses and gas masks and other personal protective equipment, regular physical examination.

8. physical and chemical properties

silicone DMC is a colorless transparent liquid with pungent odor. The relative density (water = 1) is 0.97 and the relative vapor density (air = 1) is 4.1. The boiling point is 99.5°C and the flash point is 21.7°C. Insoluble in water, miscible in most organic solvents.

9. stability and reactivity

silicone DMC is stable at room temperature, but decomposition reaction may occur under high temperature, light and acidic conditions. Contact with oxidant may cause combustion or explosion.

10. toxicological data

silicone DMC is low toxicity. Prolonged exposure or inhalation may cause neurological and respiratory effects. Animal experiments have shown that silicone DMC has a mild irritating effect on the eyes and skin.

XI. Ecological Data

Silicone DMC has certain toxicity to aquatic organisms and may cause long-term adverse effects on the aquatic environment. Discharge of silicone DMC into water bodies should be avoided.

12, waste disposal

waste silicone DMC should be in accordance with the relevant provisions of the state for disposal, shall not be arbitrarily discharged or dumped. It can be treated by incineration, and effective measures should be taken to control secondary pollution during incineration.

XIII. Transportation Information

The transportation of silicone DMC shall be carried out in accordance with the regulations on the transportation of dangerous goods. During transportation, the container shall be protected from direct sunlight and kept sealed. It is strictly prohibited to mix with oxidants, edible chemicals, etc. Transportation vehicles shall be equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment.
