Does a urea warehouse with an area of over 1,500 square meters need to be equipped with automatic sprinklers?

Urea warehouses are generally built on a large scale. According to Note 4 in Table 3.3.2 of the \"Code for Fire Protection Design of Buildings\" GB50016-2014, when the fire resistance rating is grade II, the size of fire compartments can be 1.0 times larger than the values specified in the table. However, urea is classified as a Class C material in terms of fire hazard; per Article 8.3.2.7 of the same code, automatic sprinkler systems must be installed in any single-story or multi-story warehouse storing Class C materials whose floor area exceeds 1,500 m2 or total building area exceeds 3,000 m2. I would like to ask everyone: when designing a urea warehouse with a floor area of more than 1500 m2, is an automatic sprinkler system installed?
No one has replied for such a long time……
The new regulations have improved safety standards, and that’s true. For storage facilities for urea, whether in bulk or in bags, self-priming systems are not suitable; nor are fire suppression systems, as leaks can cause serious problems. In recent years, new projects have been constructed in accordance with the standards regarding the use of fire-resistant coatings on steel structures.
I’m not sure what fire classification is assigned to urea warehouses during design. As far as I know, the fire hazard category for urea warehouses is classified as Category C. According to Article 8.3.2.7 of the Building Code, single-story or multi-story warehouses storing Category C items with a floor area of more than 1,500 m2 or a total building area of more than 3,000 m2 must be equipped with an automatic fire extinguishing system, preferably a sprinkler system.
Installing automatic sprinklers in urea warehouses meets the fire safety requirements, but it would cause environmental problems, so it’s not very practical.
