Regarding the fire hazard classification of hydrogen peroxide
Thread Content
This post was last edited by Mu Zi 928 on 2015-11-9 at 11:09. I would like to ask everyone: should the fire hazard category of 27.5% hydrogen peroxide be classified as Class A or Class B? Which specification and which clause provides the explanation for this? If you’re satisfied, feel free to give a reward :lol
It would be good to have a regulatory basis for determining whether the fire hazard category of 27.5% hydrogen peroxide falls under Class A or Class B. It belongs to Category B; refer to the Code for Fire Protection Design of Buildings
It belongs to Category B; refer to the \"Code for Fire Protection Design of Buildings\""
Which provision of the building codes states that 27% hydrogen peroxide belongs to Category B?
The provisions on the fire hazard categories in building codes provide guidelines for making such judgments: primary oxidizers are classified as Category A, while secondary oxidizers are classified as Category B. In the old **Chemical Catalogue Version 02, peroxide had a hazard code of 51001; therefore, 27.5% hydrogen peroxide is classified as a first-class oxidizing agent, and it falls under Category A in terms of fire hazards.
There are differing opinions between the 6th and 7th floors; could we discuss this further? @enpalzhk_0103 @ckwcba
They’re all so amazing; truly masters.
The 2014 version of the building codes clearly states that the classification of fire hazards related to oxidizing substances is based on the \"Rules for the Transport of Dangerous Goods\"; then why is it considered that the new \"Implementation Guidelines for the Weiyuan Chemicals Catalog (2015 version)\」is the relevant standard? Those who come first will be distinguished from those who come later – does the building code have some kind of foresight ability? Moreover, in the **Chemical Classification Information Table** attached to the Guidelines, smoking *ao acid is classified as an oxidizing liquid, Category 1; however, it is classified as Class B for fire hazards under building codes. *Aosuan ammonium, on the other hand, is classified as an oxidizing solid, Category 3, but it is classified as Class A for fire hazards under building codes. It is obvious that the correlation between the two is not very strong.
You can consult the current Regulations on the Transport of Dangerous Goods and compare them with the **Chemical Classification Information Table**; this should help you find the answer. Who has the current Rules for the Transport of Dangerous Goods? Please share it Furthermore, in my opinion, there are some discrepancies between the domestic engineering design standards and regulations; it’s not just the building design fire protection codes and the **Chemical Classification Information Table**. For example, there are also differences in the specifications for oil depot design and the road protection regulations regarding the distance that should be maintained between storage facilities for flammable and explosive liquids and roads. As for how to proceed, I believe it is necessary to seek the opinions of regulatory authorities.
