Read： 1156 Time：19months ago Source：Transform the World with Simplicity

In the field of chemical production raw materials, sulfur dioxide is a common and important chemical substance. However, due to its unique chemical properties, sulfur dioxide has certain safety risks during storage and transportation. In order to ensure the safe storage and transportation of sulfur dioxide, a series of strict specifications and standards must be followed. This article will discuss in detail the safety storage and transportation regulations of sulfur dioxide.

1. the basic properties of sulfur dioxide

sulfur dioxide is a colorless, pungent odor of the gas, soluble in water, with strong reducibility. In the air, sulfur dioxide reacts with water and oxygen to form sulfuric acid, which in turn leads to environmental problems such as acid rain. Therefore, when storing and transporting sulfur dioxide, special care must be taken to prevent its leakage and reaction with substances in the environment.

2. sulfur dioxide safety storage specification

1. Storage facilities location: should choose higher terrain, good ventilation, away from fire and heat sources of the local construction of storage facilities. At the same time, the storage of sulfur dioxide in basements, semi-basements or confined spaces should be avoided.
2. Storage container selection: A container with good sealing performance and corrosion resistance should be selected to store sulfur dioxide, such as stainless steel or glass steel containers. Vessels shall be regularly overhauled and maintained in good condition.
3. Storage environment control: Ventilation equipment shall be installed in storage facilities to maintain air circulation. At the same time, the temperature and humidity in the facility should be controlled to avoid the reaction of sulfur dioxide with water and oxygen in the air.
4. Safety identification setting: obvious safety identification shall be set around the storage facilities, including warning signs such as flammable, toxic and corrosive. At the same time, safety operation procedures and emergency plans shall be set up inside the facility.

3. sulfur dioxide safety transportation specifications

1. Selection of transportation vehicles: transportation vehicles with professional qualifications and meeting relevant standards should be selected for the transportation of sulfur dioxide. The vehicle shall have good sealing performance and anti-leakage measures.
2. Transport personnel training: Transport personnel should receive professional safety training to understand the nature, hazards and emergency treatment measures of sulfur dioxide. In the process of transportation, we should be vigilant, find and deal with abnormal situations in time.
3. Transportation route planning: reasonable transportation routes should be selected to avoid passing through densely populated areas and environmentally sensitive areas. At the same time, you should understand the road conditions and weather conditions along the way to ensure transportation safety.
4. transport packaging specification: sulfur dioxide packaging should meet the relevant standards, packaging containers should be strong, sealed, can effectively prevent leakage. On the outside of the package should be marked with dangerous goods signs and transport precautions.

4. emergency treatment measures

in the storage and transportation of sulfur dioxide, such as leakage and other emergencies, should take the following emergency treatment measures:

1. Immediately start the emergency plan, organize personnel evacuation and report to the superior.
2. Use special equipment to recycle the leaked sulfur dioxide to avoid its diffusion into the environment.
3. If a person becomes unwell after exposure to sulfur dioxide, he or she should be immediately sent to hospital for treatment.

In short, in order to ensure the safe storage and transportation of sulfur dioxide in the field of chemical production raw materials, it is necessary to strictly abide by relevant norms and standards, strengthen management and training, and improve safety awareness. Only in this way can we effectively guarantee the safety of people's lives and property and the safety of the ecological environment.
