Is lubricating oil a hazardous chemical?

According to the national GB6944-86 "Preparation and Name of Dangerous Goods", commonly used dangerous chemicals are divided into 7 categories according to their main hazardous characteristics: Category 1: Explosives; Category 2: Compressed gases and liquefied gases; Category 3 : Flammable liquids; Category 4: flammable solids, self-igniting items, and flammable items when wet; Category 5: oxidants and organic peroxides; Category 6: toxic substances; Category 7: corrosive substances. Among them, the first five categories are explosive dangerous goods, and many substances in the last two categories are also explosive dangerous goods.

So the characteristics of lubricating oil: first, it is not flammable; second, it is not corrosive; third, it is not volatile; fourth, it is not easy to package; fifth, it is not easy to store and transport. . Therefore, lubricants are not classified as dangerous goods and do not need to comply with regulations on the transportation and storage of dangerous goods. However, lubricants are also chemical products and must be stored and transported safely to avoid environmental pollution.

To determine whether lubricating oil is a flammable and explosive hazardous chemical, you must first understand the flash point of the product.

Flash point is an item that indicates the tendency of petroleum products to evaporate and their safety properties. Those with a flash point below 45°C are called flammable products; those with a flash point above 45°C are called flammable products. Lubricating oil products come in various forms and specifications, but the flash point of general lubricating oil is around 220°C, the flash point of poor quality is also above 170, and only a small amount of insulating oil has a flash point around 140°C. Therefore, the risk of fire from lubricating oil is relatively low. It is worth noting that base oil, as the main raw material of lubricating oil, although it does not meet the standards of lubricating oil in some aspects of performance, is the same as lubricating oil in terms of basic indicators such as flash point.

Therefore, judging from the flash point of lubricating oil, it does not have the characteristics of flammable products; secondly, it is not highly corrosive; thirdly, it is not volatile; fourthly, it is not easy to pack; fifthly, it is not difficult to pack. Storage and transportation. Therefore, lubricating oil is not classified as dangerous goods and does not need to comply with the regulations on the transportation and storage of dangerous goods. Although lubricating oil is not classified as flammable, it is combustible. The material of barreled lubricants is some kind of plastic. All lubricants and plastics will become combustion aids when exposed to open flames. Therefore, during the storage and transportation of lubricating oil, relevant fire safety regulations must be implemented, fireworks must be strictly prohibited, and complete fire-fighting equipment should be installed. When storing and transporting lubricating oil products, you need to pay attention to the following aspects:

1. They must be distinguished according to their name, nature and brand name. The containers used to hold products must be complete, clean, leak-proof, and inspected to meet the requirements before they can be used. 2. When the temperature is low in winter, when transporting base oil with high viscosity and easy condensation, steam heating coils or insulated trucks with heating equipment can be used for unloading. 3. Larger containers (such as oil tanks) must regularly inspect and test the oil and clean the accumulated residue and dirt at the bottom of the container. 4. When opening and closing the lid of the container, a special wrench must be used. Chisels and hammers are not allowed to avoid sparks and fires.
