Read： 587 Time：19months ago Source：Transform the World with Simplicity

Selenium dichloride is an important raw material for chemical production, which is widely used in medicine, pesticide, pigment and other fields. However, due to its strong toxicity and corrosiveness, strict compliance with relevant safety regulations is required during storage and transportation. This article will detail the safety storage and transportation specifications for selenium dichloride.

1. the properties and hazards of selenium dichloride

Selenium dichloride is a colorless or pale yellow crystalline powder with a strong pungent odor. It is soluble in water, alcohol, ether and other organic solvents, but insoluble in petroleum ether. Selenium dichloride is easy to absorb moisture in the air, and decomposes to produce hydrogen selenide and hydrochloric acid, which is highly corrosive.

selenium dichloride has a strong irritation to the eyes, skin and respiratory system. Long-term exposure can lead to chronic poisoning and cause lesions of the nervous system, digestive system and cardiovascular system. Acute poisoning can appear headache, dizziness, nausea, vomiting and other symptoms, severe cases can lead to coma, death.

2. selenium dichloride storage specification

1. storage place should be dry, well ventilated, avoid direct sunlight.
2. The storage container shall be made of corrosion resistant materials, such as polyethylene and polypropylene.
3. Storage should be away from fire sources, heat sources, to avoid contact with reducing agents, alkali metals and other items.
4. In the storage process, safety inspection should be carried out regularly, and any abnormal situation should be handled in time.

3. selenium dichloride transport specification

1. should check the packaging is intact before transport, if there is damage should be dealt with in a timely manner.
2. During transportation, vibration, friction and impact should be prevented to avoid package damage.
3. Transportation vehicles shall be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment.
4. During transportation, avoid high temperature, open flame and electrostatic spark, and keep away from inflammable and explosive materials.

4. selenium dichloride leakage emergency treatment

1. In case of leakage, the leakage source should be cut off immediately, mixed with sand, dry lime or soda ash and recycled to the waste treatment site for disposal.
2. In case of large leakage, embankments or pits shall be constructed for containment, which shall be transferred to tankers or special collectors by pumps, and recycled or transported to waste treatment sites for disposal.
3. Emergency treatment personnel should wear protective equipment to avoid direct contact with leakage.

5. selenium dichloride safety operation specification

1. Operators must be specially trained and strictly abide by the operating procedures.
2. Wear protective equipment such as protective gloves and protective glasses during operation.
3. Dust should be avoided during operation. If dust is generated, it should be cleaned in time.
4. After the operation, the operation site shall be cleaned to ensure that there is no residue.

6. conclusion

selenium dichloride as an important raw material for chemical production, its safety and storage and transportation regulations are of great significance to ensure production safety and personnel health. Therefore, in the actual production process, the relevant safety regulations must be strictly observed to ensure the safe and reliable storage and transportation of selenium dichloride.
