I would like to ask: for three storage tanks containing concentrated hydrochloric acid at a concentration of 30%, are there any regulations requiring the construction of fire dikes?

Such storage tanks need to be considered based on their specific function. If they are used for storage, then a dike is required; the volume of such a dike is generally determined based on the storage capacity of a single tank. If the tanks are located in a production area and serve only as buffers, then there is no requirement for a dike, but one is still needed to prevent contamination. Depending on the number of tanks, it should be considered a tank farm, and therefore a dike is definitely necessary

There are no requirements in the fire safety codes. However, since hydrochloric acid is a highly corrosive medium, an anti-corrosion dike D should be installed; the volume of such a dike should be calculated using the same methods as for fire dikes (it is not recommended to set a minimum height)

Regarding storage tanks for concentrated hydrochloric acid, the main safety considerations are generally related to dealing with acid corrosion and leaks, rather than fires. Since hydrochloric acid is not flammable, it is generally not necessary to construct fire dikes. However, if there are flammable or explosive materials or devices around the storage tank, in accordance with the general principles of chemical plant layout design, fire sources should be avoided as much as possible. Regarding the requirements for the volume of the dike, it must be capable of holding the maximum amount of leakage from the tank’s particles; generally, it is required that the volume of the dike be at least equal to the maximum capacity of the tank. It should be emphasized, however, that the above conclusions are all based on general chemical safety rules. The actual design and operation must strictly comply with the specific environmental protection and industrial safety regulations in your area. If you have specific situations or questions, it is recommended that you consult a professional safety engineer or relevant **organizations**. .

GB 50984-2014 Code for Layout Design of Petrochemical Plants

The regulations do not specify this, but what should you do if the inspection experts recommend it later on?

Refer to the draft of the Code for Design of Acid-Base Tank Areas.

At present, hydrochloric acid is regulated as a chemical that is easy to use for manufacturing//////poisons; the specific requirements are determined by the local public////security authorities. Dikes, **** systems, and similar measures are all necessary

A cofferdam must be built, not a fire dike

A dike needs to be built; otherwise, leaks can easily corrode the ground and other equipment
