I would like to ask whether 30% hydrogen peroxide is classified as Category B or Category C
Thread Content
According to the building codes, it seems to meet the requirements for both Category B and Category C; by checking the list of hazardous chemicals, it can be classified as Category B. I would like to ask whether it can be classified as Category C instead
It must be done strictly; why lower it?
According to the classification standards for hazardous chemicals, Category B and Category C are two distinct classifications. Hazardous chemicals of Category B are relatively dangerous substances, while those of Category C are relatively safer. 30% hydrogen peroxide is an oxidizing substance, and in accordance with the recommended usage guidelines and safety procedures, it is generally classified as a Category B hazardous chemical. This is because oxidizing substances can, under certain conditions, cause fires, explosions, or the generation of toxic gases and other hazards. Although in some cases, depending on specific circumstances, certain oxidizing substances can be classified as Category C, under normal conditions, 30% hydrogen peroxide should be treated as a hazardous chemical of Category B. It is recommended that you handle and store this chemical properly in accordance with relevant regulations and standards. .
If it isn’t strict enough, it won’t pass censorship; but making changes to it is quite a hassle
It is completely understandable that companies wish to reduce risks and improve control over hazardous chemicals. However, hazardous chemicals are classified based on their potential hazards, and there are relevant regulations and standards to guide their safe use and management. When handling 30% hydrogen peroxide, to ensure the safety of employees and the environment, it is recommended to treat and store it as a Category B substance due to its high level of hazard. This helps to avoid potential security risks and accidents that might occur. Enterprises should comply with relevant laws and standards, and take appropriate protective measures to ensure the safety of employees and the environment. If you have any questions, it is recommended to consult relevant security experts or departments. .
The fire hazard level of the hydrogen peroxide production plant is Class A； The fire hazard level for storage facilities containing aqueous hydrogen peroxide solutions (with a hydrogen peroxide content of over 60%) is Class A ； The fire hazard classification for storage facilities containing aqueous hydrogen peroxide solutions (with a hydrogen peroxide content of not less than 20% but not more than 60%) is Category B ； The fire hazard classification for storage facilities containing aqueous hydrogen peroxide solutions (with a hydrogen peroxide content of 8% or more, but less than 20%) is Class C ； Aqueous hydrogen peroxide solutions (with a hydrogen peroxide content of less than 8%) are not considered hazardous chemicals, and the fire hazard classification for storage facilities is Class V. Reference can be made to the \"List of Names of Dangerous Goods\" GB 12268-2012, the \"Method for Classifying Packaging for the Transport of Dangerous Goods\" GB/T 15098-2008, the \"Specifications for the Classification and Labelling of Chemicals – Part 14: Oxidizing Liquids\" GB 30000.14-2013, and the \"General Technical Requirements for Packaging Used in the Transport of Dangerous Goods\" GB 12463-2009.
:handshake:handshake Thank you so much
May I ask if there are any relevant standards for the design of semi-underground storage pits for hydrogen peroxide?
Check the “Catalog of Hazardous Chemicals 2022”: Hydrogen peroxide solution with a concentration of ≥60%, an oxidizing liquid, Category 1. Oxygen, oxidizing gas, Category 1. Since hydrogen peroxide solutions with a concentration of ≥60% are classified as Category A, why is oxygen classified as Category B according to building codes?
