In the field of chemical production raw materials, the safety of white phosphorus storage and transportation specifications

1. Introduction

White phosphorus is a very important chemical production raw material, because of its unique chemical properties, is widely used in various fields. However, white phosphorus is also a highly dangerous substance, which can spontaneously ignite in the air and is toxic, causing serious harm to human health and the environment. Therefore, in the field of chemical production raw materials, the safe storage and transportation of white phosphorus must be strictly observed to ensure personnel safety and environmental protection.

2. the nature and harm
of white phosphorus
white phosphorus is a colorless and transparent crystal with high reactivity. In the air, white phosphorus will react with oxygen, generating a lot of heat, resulting in spontaneous combustion. In addition, white phosphorus is also toxic. Long-term exposure or inhalation of white phosphorus vapor can cause symptoms of poisoning, including headache, dizziness, nausea, vomiting, abdominal pain, diarrhea, etc. In severe cases, it can lead to coma and death.

3. white phosphorus safety storage specification

1. Storage facilities: white phosphorus should be stored in a cool, dry, well-ventilated special warehouse, away from fire, heat and direct sunlight. The warehouse floor should be laid with anti-static materials, and set up fire and explosion-proof facilities.
2. Storage container: White phosphorus should be stored in a well-sealed container, and the container should have anti-static, anti-leakage, anti-fire and other safety properties. The storage container shall be regularly inspected and maintained to ensure that it is in good condition.
3. Storage management: A sound white phosphorus storage management system should be established, with a clear storage capacity and storage period, and a designated person responsible for management. Obvious safety warning signs shall be set up in the storage area, and corresponding fire fighting equipment and first aid medicine shall be provided.

4. white phosphorus safety transport specification

1. transport vehicles: white phosphorus should use special dangerous goods transport vehicles, vehicles should comply with the relevant national standards, with fire, explosion, anti-static and other safety performance.
2. Transport packaging: The transport packaging of white phosphorus should meet national standards, have sufficient strength and sealing performance, and be able to prevent white phosphorus leakage and spontaneous combustion. Dangerous goods signs and transportation precautions shall be marked outside the package.
3. Transportation routes: Safe transportation routes should be selected to avoid passing through densely populated areas and sensitive environmental areas. During transportation, the vehicle speed should be kept stable to avoid sudden braking and bumps.
4. Transport personnel: Transport personnel should be professionally trained, familiar with the nature and hazards of white phosphorus, and master transportation safety knowledge and emergency handling skills.

5. emergency treatment measures

in the storage and transportation of white phosphorus, such as leakage, spontaneous combustion and other emergencies, should take the following emergency treatment measures:

1. Immediately start the emergency plan, organize personnel to evacuate the dangerous area, and report to the relevant departments.
2. Use dry powder, foam and other fire fighting equipment for fire fighting, and prohibit the use of water for fire fighting.
3. Use special equipment to recycle the leaked white phosphorus to avoid environmental pollution.
4. Give first aid to the injured and send them to hospital for treatment.

6. conclusion

white phosphorus is an important raw material for chemical production, and its safe storage and transportation are very important. Relevant national regulations and standards should be followed, a sound management system and operating specifications should be established, and personnel training and education should be strengthened to ensure the safety of storage and transportation of white phosphorus. At the same time, regular safety inspections and maintenance should be carried out to discover and eliminate potential safety hazards in time to ensure personnel safety and environmental protection.
