How are the area and height of the cofferdam for Class A storage tanks determined?
Thread Content
There is a hydrogen peroxide storage tank in the tank area; the other tanks are located 10 meters away from it. I was thinking of constructing a separate cofferdam, but I’m not sure what criteria should be used to determine the size and height of this cofferdam I would be grateful for the guidance from the experts!
Following the accident in Tianjin, the State Administration of Work Safety has required all chemical plants to use individual dikes for each hazardous storage tank (according to NFPA, a value of 3 or higher is sufficient for this requirement), with the minimum area of such dikes being determined by the volume of the storage tank.
Excuse me, expert :) – what is NFPA?
The fire safety codes in the United States are issued by their Fire Association
The single-tank single-dike design was introduced long ago, not because of the Tianjin accident.
Check the concentration of hydrogen peroxide. 35% or higher is considered Class A
Oh, I see. Where is this regulation specified? Could you please send it to me? Email address: pbh19860218@163.com. Thank you. I also have another question: Is it allowed to install a 30-cubic-meter storage tank for 30% hydrogen peroxide inside Class A tank areas? Thank you
{:3_63:} It was our chief engineer who said that. I checked the explanatory notes accompanying Code for Building Design 50016, but it also does not specify the boundary for this content level. You might want to refer to the MSDS. http://www.ichemistry.cn/msds/556.htm。 Additionally, 30% of the storage tanks in Class A tank areas can be used for storing hydrogen peroxide; it is important to check for any materials that may react with hydrogen peroxide.
