Dangerous goods are not very far away from us, and we also come into contact with some parts in our daily lives. For example, we often hear voice announcements on buses saying, "Please do not carry flammable, explosive and other items.". The terms "flammable and explosive" here belong to the category of "nine dangerous goods".
So how to distinguish these dangerous goods when encountering them in daily life? How should we transport safely? I will organize in detail for everyone:
1. Explosives
These types of chemicals undergo intense chemical reactions under external heating, impact, and other effects, instantly generating a large amount of gas heat, causing the surrounding pressure to rise and explode. During transportation, it is important to ensure that the goods are stored in a dry and cool environment, and to secure them to prevent collisions.
2. Compressed gas and liquefied gas
These types of chemicals are similar to explosives, and when subjected to external forces, they can cause containers to explode and rupture, or gas cylinder valves to leak, leading to fire or poisoning. During transportation, the pressure vessels used to store products should be specially fixed, and the sealing of the container valves should also be checked regularly.
3. Flammable liquids
These types of chemicals are liquids, liquid mixtures, or solid substances that are prone to volatilization at room temperature, and the resulting steam and air mixed can cause explosions. Pay attention to sealing during transportation to prevent evaporation.
4. Flammable solids, self igniting chemicals, and flammable chemicals in contact with moisture.
When exposed to water or moisture, it will release a large amount of flammable gases and heat, and even burn or explode. Pay attention to storing such items in a dry and cool environment during transportation.
5. Oxidants and organic peroxides
These types of chemicals themselves may not necessarily be flammable, but they can cause combustible materials to burn or even explode. It should be securely fixed during transportation to prevent shaking.
6. There are drugs present
Mainly, contact with the body can cause pathological conditions and even endanger life. Be sure to seal the transportation to prevent any contact with the human body.
7. Radioactive chemicals
Invisibly, it can cause great harm to the human body, such as radium, uranium, etc. During transportation, the corresponding containers must be properly sealed.
8. Corrosive products
It can burn human tissues or cause damage to metals, etc. During transportation, glass cans are mostly used for packaging, and attention should be paid to the protection of the containers.
9. It mainly refers to magnetic objects that have properties such as anesthesia and toxicity, and can have an impact on flight. Before transportation, the goods should be demagnetized and sealed.
Personnel using "nine types of hazardous materials" must be familiar with the nature and protection knowledge of hazardous materials, operate with caution, and ensure safety.
