Gas cylinder color marking list

The list of gas cylinder color symbols is as follows:

Acetylene, chemical formula: C2H2, the bottle color is white, the word Acetylene must not be near the fire, the word color is big red.

Hydrogen, chemical formula: H2, bottle color is light green, the word is hydrogen, the word is big red.

Oxygen, chemical formula: O2, bottle color is light blue or phthalo blue, the word color is oxygen black.

Nitrogen, chemical formula: N2, bottle color is black, word color is light yellow.

Air, chemical formula: none, bottle color is black, word color is white.

Carbon dioxide, chemical formula: CO2, bottle color is aluminum white, lettering is liquefied carbon dioxide, lettering is black.

The role of gas cylinders classified by color

1, identify the type of gas: different types of gases have different chemical properties and dangerous. Through the gas cylinder coated with different colors, and in the gas cylinder marked with the name of the gas and other signs, you can intuitively distinguish the type of gas, to avoid misuse. For example, oxygen cylinders are blue, acetylene cylinders are white, carbon dioxide cylinders are aluminum white and so on.

2, improve safety: through the gas cylinder by color classification, can let the user more easily identify the type of gas and dangerous. For some dangerous gases, such as hydrogen, oxygen, etc., users need to pay extra attention during storage and use. Color classification can remind users to pay attention to safe use and improve safety.

3, easy to manage: different types of gases have different regulations and requirements for storage, transportation and use. By classifying gas cylinders by color, different types of gases can be easily identified, which is convenient for management personnel to manage and supervise. This helps to ensure the safety of gas storage and transportation, as well as the legality and standardization of use.

4, reduce the risk: gas cylinders classified by color can reduce the risk of misuse of gas leading to safety accidents. For some gases with high risk, such as hydrogen and oxygen, if misused or improperly managed, they may cause fire, explosion and other serious accidents. Through color classification, misuse of gases can be effectively avoided and safety risks can be reduced.
