Question 2: What are dangerous goods and what are their dangerous characteristics? Dangerous goods refer to goods with spontaneous combustion, flammability, explosion, corrosion, poison and radioactivity, which can be implemented with reference to the transport rules of dangerous goods promulgated by the Ministry of Communications. The concept of dangerous goods refers to goods with spontaneous combustion, flammability, explosiveness, corrosiveness, toxicity and radioactivity.
Question 3: What goods are dangerous goods? According to the Classification and Commodity Name Number of Dangerous Goods (GB 6944), all goods that are explosive, flammable, toxic, corrosive and radioactive, and need special protection during transportation, loading, unloading, storage and storage are dangerous goods. Dangerous goods are divided into nine categories:
1 explosives (explosives)
Category 2 compressed gas and liquefied gas.
Class 3 flammable liquid (flammable liquid II ids)
Category 4: flammable solids, spontaneous combustion substances and flammable substances when wet (flammable solids are easily scooped up by a spoonful, and flammable gas substances are released when wet).
Category 5 oxidants and organic peroxides.
Category 6 Poisons and Infectious Substances.
Class 7 radioactive substances (radioactive substances)
Grade 8 corrosive agent.
All kinds of dangerous substances (Category 9)
Various types can be divided into several items.
In addition, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the National Standardization Administration of China issued a new version of the List of Dangerous Goods (GB 12268-2005) in 2005.
Question 4: How to use sunscreen? Hello, I'm glad to help you.
Neutrogena Clear Sunscreen has two choices: SPF30 and SP55, which contain Neutrogena patented ingredients and broad-spectrum sunscreen technology. Compared with other brands of sunscreen products, the sunscreen time is longer and the sunscreen effect is more stable, because after a long period of use, even the products with higher SPF have weakened their ability to protect against ultraviolet A waves. Neutrogena sunscreen has broad-spectrum sunscreen technology, so this problem is avoided. Refreshing and not greasy, you can try it at the counter before deciding. It is waterproof, sweat-proof and friction-proof. During SPF's sun protection time, absolutely avoid sunburn-I think this is something that other brands absolutely dare not promise. I learned to drive in July and have been using this sunscreen product. I drive around every day. The sun is so big that I really don't get a tan. You can really try. It was introduced to me by a friend. Sold out of stock in Hong Kong and won awards in many famous American fashion magazines.

Question 7: What does a class of dangerous goods contain? Classification of dangerous goods and product name number (GB6944-2005)
1 explosive
This kind of articles refers to the articles that can undergo violent chemical reaction under the external action (such as heating and impact), produce a lot of gas and heat instantly, make the surrounding pressure rise sharply and explode, and cause damage to the surrounding environment. It also includes fireworks that do not have the overall explosion risk, but have the risk of burning, throwing and small explosion, or only produce one or more functions such as heat, light, sound and smoke.
This kind of goods are divided into five categories according to their danger.
Item 1 Substances and articles with collective explosion risk.
Item 2: Substances and articles that are in danger of ejection but not in danger of collective explosion.
Item 3: Substances and articles with fire hazard, slight explosion hazard or slight ejection hazard, or both, but generally without explosion hazard.
Item 4: Substances and articles without major hazards. The goods in this item are less dangerous. If they are ignited or ignited, their dangerous effects are mostly confined to the inside of the package, but there is no great danger to the outside of the package.
The goods in item 5, extremely insensitive explosive substances, are relatively stable in nature and will not explode in the fire test.

The second category is gas, which is category II 1, category II 2 and category II 3 respectively;
The third category is flammable liquids;
The fourth category: floating combustible solids, substances liable to spontaneous combustion, and substances that give off combustible gas when meeting water, which are 1, 2, 3 respectively;
The fifth category is oxidizing substances and organic peroxides, which are five categories 1 and two categories;
