6.1 Overview
6.1.1 For the labels of oxidizing gases, the hazard categories are listed in the order of designated pictograms, signal words and hazard statements. The hazard types or categories covered by the United Nations "Recommendations on the Transport of Dangerous Goods Model Regulations" (Seventeenth Revised Edition) (hereinafter referred to as the Model Regulations) should list the designated corresponding graphic signs for each category on the label. The allocation of label elements for oxidizing gases is shown in Appendix B. 6.1.2 For the classification standards and label elements for oxidizing gases, see Appendix C6.1.3 The information required on the label includes hazard pictograms, signal words, hazard statements, precautionary statements, product identifiers and supplier identification. Note: For other label elements that have not been standardized, such as additional instructions, they also need to be included on the label. The competent authority may also require additional information, and the supplier may also add supplementary information.
6.2 Hazard pictograms
Hazard pictograms should use black symbols with a white background and a red frame that is wide enough to make them eye-catching. The hazard pictograms specified in the Model Regulations are shown in Appendix B. 6.3 Signals
Signals are words used on labels to indicate the relative severity of a hazard and to alert readers to potential hazards. For oxidizing gases, the signal word "Danger" is used.
Hazard Statements
Hazard statements are phrases assigned to a hazard category that describe the hazardous nature of the hazard and, where appropriate, the degree of hazard of the hazard.
Oxidizing gas hazard statements refer to Appendix
6.5 Precautionary statements
Precautionary statements are words (and/or pictograms) describing recommended measures to minimize or prevent adverse effects resulting from exposure to the hazardous product or from improper storage or handling of the hazardous product. For this purpose, there are five categories of precautionary statements: general, prevention, emergency, storage and disposal. For oxidizing gas precautionary statements refer to Appendix D. 6.6 Product identifiers
6.6.1 The product identifier shall be used on the label and shall be consistent with the product identifier used on the full technical instructions for the chemical product. If a substance or mixture is listed in the Model Regulations, the correct UN shipping name shall also be used on the packaging. 6.6.2 The label shall include the chemical name of the substance. For mixtures or alloys: When acute toxicity, skin or respiratory sensitization or specific target organ toxicity appear on the label, the label shall include the chemical composition of all ingredients or alloying elements that may contribute to these hazards. The competent authority may require that the chemical names of all ingredients or alloying elements that may contribute to the hazards of the mixture or alloy be listed on the label. 6.7 Supplier identification
The name, address and telephone number of the manufacturer or supplier of the substance or mixture shall be provided on the label. 6.8 Label examplesbzxz.net

Decision logic and guidance

For the classification of oxidizing gases, the test or calculation method described in GB/T 27862 shall be used. The classification shall be carried out according to the decision logic in Figure A.1.

Decision logic for oxidizing gases
A.2 Guidance
An example of the classification of oxidizing gas mixtures by calculation according to GB/T 27862. The classification method described in GB/T27862 adopts the standard that if the oxidizing power of a gas mixture is greater than 23.5%, it is considered that the oxidizing power of the gas mixture is greater than that of air. The oxidizing power (OP) is calculated by formula (A, 1): Op
Wherein:
The molar concentration of the main oxidizing gas in the mixture: C
The oxygen equivalence coefficient of the oxidizing gas in the mixture; The equivalence coefficient of the inert gas and nitrogen: The molar concentration of the largest inert gas in the mixture; X100%

The total number of oxidizing gases in the mixture:
The total number of inert gases in the mixture.
Example of a mixture:
9%(O,)+16%(N,O)+75%(He)
Calculation steps:
Step 1: For non-flammable and non-oxidizing gases, determine the oxygen equivalence coefficient (C) of the oxidizing gas in the mixture and the equivalence coefficient (K,) of the inert gas in the mixture compared to nitrogen. C,(N,O) 0.6 (nitrous oxide)
C(02)=1 (oxygen)
K,(He)=0.9 (ammonia)
b) Step 2: Calculate the oxidizing capacity of the gas mixture. rc
OP=20.1%<23.5%
0.09X1+0.16X0.6
X100%=20.1%
0.09+0.16+0.75×0.9
Therefore, the mixture is not considered to be an oxidizing gas. The allocation of label elements is shown in Table B.1.
