Oxygen cylinders are not dangerous goods, and is liquid oxygen a hazardous chemical?

Oxygen. It is a dangerous good. Oxygen is a type of combustible dangerous goods, which is not necessarily flammable in itself, but usually due to the release of oxygen or oxidation reactions.

Substances that may cause or cause the combustion of other substances.

Regulations on the Safety Management of Hazardous Chemicals.

Article 3 The hazardous chemicals mentioned in these Regulations refer to highly toxic chemicals and other chemicals that are toxic, corrosive, combustion, combustion-supporting, etc., and are harmful to the human body, facilities and the environment.

Oxidation. Liquid classification, warning labels and cautionary instructions are available in GB20589. A gaseous liquid is a liquid that does not inherently combust, but the release of oxygen may cause or cause the combustion of other substances.

An oxidizing gas is any gas that causes or causes the combustion of other substances, generally by providing oxygen more than air.

Oxygen cylinder is a high-pressure vessel for storing and transporting oxygen, which is generally made of alloy structural steel hot stamping and pressing, and is cylindrical. It is used in hospitals, first aid stations, and nursing homes.

The shoulder of the cylinder is marked with a steel stamp of working pressure, test pressure, volume, weight, etc., and the surface is painted sky blue, and the word "oxygen" is written in black.

It is a dangerous substance belonging to the fifth category of hazardous chemicals, item 1: a substance that is not necessarily flammable in itself, but may cause or promote the combustion of other substances due to the release of oxygen or oxidation reactions.

Oxygen cylinders are not considered dangerous goods.

In the promulgated "List of Hazardous Chemicals", liquid oxygen belongs to the first category, and non-flammable gases in compressed gas and liquefied gas belong to non-flammable and non-toxic gases.

Because the boiling point of liquid oxygen is extremely low, which is -183, when the liquid oxygen "runs, rises, drips, and leaks" accidents, once the liquid oxygen is splashed on the person's **, it will cause a serious frostbite accident. Under normal pressure, when the concentration of oxygen exceeds 40%, it may cause oxygen poisoning, and when inhaling a mixture of gas with a concentration of 40%-60% oxygen, there will be retrosternal discomfort, light cough, and then chest tightness, retrosternal burning sensation and dyspnea, and cough will be aggravated; In severe cases, edema and even respiratory distress syndrome develop. When the inhaled oxygen concentration is more than 80%, facial muscle twitching, coma, respiratory failure and death occur.

Long-term exposure to an oxygen partial pressure of 60kPa-100kPa (equivalent to 40% of oxygen concentration) can cause eye damage and, in severe cases, blindness.

Summary. Kiss, new oxygen cylinders empty cylinders are not dangerous goods. However, as long as the empty oxygen cylinder has been inflated, it is dangerous goods, unless it is a gas cylinder that has just left the factory, otherwise it is punished as transporting dangerous goods.

Related Expansion: Empty oxygen cylinders are dangerous goods as long as they have been inflated, unless they are gas cylinders that have just left the factory, they will be punished as transporting dangerous goods if they are caught. It belongs to the fifth category of hazardous chemicals, item 1 oxidizing substance:

Substances that are not necessarily flammable in themselves, but are likely to cause or cause the combustion of other substances by releasing oxygen or by oxidizing reactions. Oxygen cylinders should be no less than 10m away from the source when placed or transported. Leave the heat source not less than 1m.

In summer, when working outdoors in the sun, it must be covered with canvas, etc., in case of **.

Oxidizing substances belonging to Category 5 Item 1 of Hazardous Chemicals: Substances that are not necessarily flammable in themselves, but may cause or cause other substances to burn their bonds due to the release of oxygen or the oxidation reaction caused by the sail.

Oxygen cylinders should be no less than 10m away from the source when placed or transported. Leave the heat source not less than 1m. In summer, when working outdoors in the sun, it must be covered with canvas, etc., in case of **.

Even if it is a new empty oxygen cylinder, you need to pay attention to safety during transportation.

Oxygen is classified as a dangerous good.

Oxygen in the "List of Hazardous Chemicals" hazard code is 22001, itself is not necessarily flammable, but usually due to the release of oxygen or oxidation reaction may cause or promote the combustion of other substances.

Oxygen is chemically more reactive. In addition to rare gases and small reactive metals such as gold, platinum, and silver, most of the elements can react with oxygen, and these reactions are called oxidation reactions, and the compounds produced by the reaction (two elements make up the world, and one element is oxygen) are called oxides.

Precautions for dangerous goods:

1. Pay attention to packaging: dangerous goods should be packed in a safe way according to their nature, transportation distance, and road conditions along the way before shipment. The packaging must be firm and tight, and the packaging should be clearly marked and easy to identify.

2. Pay attention to loading and unloading: the roads, lights, signs, and fire-fighting facilities at the dangerous goods loading and unloading site must meet the conditions for safe loading and unloading. When loading and unloading dangerous goods, the car should be parked in the open air, and the stevedores should pay attention to their own protection and wear the necessary protective equipment.

Strictly abide by the operating procedures, light loading, light unloading, it is strictly forbidden to fall, impact, roll, heavy pressure and inversion, afraid of wet goods should be covered with tarpaulin, the goods must be stacked neatly, bundled firmly. <>

Oxygen is featured in the Hazardous Chemicals.

The hazard regulation number in the list is 22001, which belongs to hazardous chemicals.

Oxygen is chemically more reactive. With the exception of rare gases and less reactive metal elements such as gold, platinum, and silver, most of the elements can react with oxygen, and these reactions are called oxidation reactions.

The compounds produced by the reaction (composed of two elements, one of which is oxygen.

It is called an oxide.

Oxygen is mainly used.

Smelting process: In the steelmaking process, high-purity oxygen is blown, and oxygen reacts with carbon and phosphorus, sulfur, silicon, etc., which not only reduces the carbon content of steel, but also helps to remove impurities such as phosphorus, sulfur and silicon.

Chemical industry: In the production of synthetic ammonia, oxygen is mainly used for the oxidation of raw gas to strengthen the process and increase fertilizer production. Another example is the high-temperature cracking of heavy oil and the gasification of pulverized coal.

Defense industry: liquid oxygen.

is the best accelerant for modern rockets in supersonic aircraft.

Liquid oxygen is also needed as an oxidant, and the combustible substance has strong resistance after being impregnated with liquid oxygen, which can be used to make liquid oxygen explosives.

Healthcare: Breathing: When used in hypoxic, hypoxic or anaerobic environments, such as diving operations, mountaineering, high-altitude flight, astronautics, medical rescue, etc.

Others: It acts as an accelerant with acetylene in itself.

Propane and other combustible gases are used together to achieve the role of welding and cutting metals, which is widely used in all walks of life, especially in machinery enterprises, and is also very convenient for cutting, which is the preferred cutting method.

Oxygen is a dangerous chemical, and I had to go through it safely, and this kind of preservation will cause some harm, so maybe maybe it must be preserved.

Objectively speaking, it is a hazardous chemical, which can be used in hospitals to treat diseases and save lives. Used in industrial machinery, if it causes a chemical reaction at high temperature, it becomes a hazardous chemical.

Oxygen is coarse based on hazardous chemicals. Oxygen is listed in the "List of Hazardous Chemicals" as 22001, which is not necessarily flammable in itself, but is usually a substance that may cause or promote the combustion of other substances due to the release of oxygen or oxidation reactions.

Oxygen is chemically more reactive. In addition to rare gases and small reactive metal elements such as gold, platinum, and silver, most of the elements can react with oxygen, and these reactions are called oxidation reactions, and the compounds produced by the reactions (composed of two elements, one of which is oxygen) are called oxides.

Belong. Oxygen is a hazardous chemical. Oxygen itself is not necessarily flammable, but it is a substance that may cause or cause the combustion of other substances by releasing oxygen or by oxidizing reactions.

Oxygen is chemically more reactive. With the exception of noble gases and less reactive metallic elements such as gold, platinum, and silver, most of the elements can react with oxygen, and these reactions are called oxidation reactions.

Sulfur dioxide. It is the main harmful gas of air pollution in China. It is mainly used in the burning of coal and oil, and is widely present in the atmosphere. It disrupts the normal growth of plants.

Fluoride. It mainly comes from the exhaust gas emitted by factories producing phosphate fertilizers, metallurgy, glass, enamel, plastics, bricks and tiles, as well as factories that use coal as the main energy source.

Nitride. It is a general term for various nitrogen oxide-containing derivatives. It is mainly used in automobile exhaust, boilers and gases emitted by some pharmaceutical factories.
