In an storage area (storage material will be plastic bottles for juice and milk) we have to provide sprinkler system. Although, the storage hazard is light but client is asking for sprinkler system. The ceiling height is 20 meters. We cannot provide false ceiling and also we cannot provide in rack sprinklers.
My question is what type of sprinklers would be best for this application ESFR, CMDA, CMSA or normal sprinklers with k factor 5.6. because NFPA 13 does not address 20 meter ceiling height problems.
I need expert advice or any solution for the problem.
