we would like to design sprinkler system for Bio gas storage, if following NFPA13, what is the density should I use?
Please refer to products photo attached
The products can be considered Class III or even Class IV commodities. Density will depend on what storage design approach is used (CMDA, CMSA or ESFR). You should confirm with the owner's insurance company or the local AHJ the type of commodity classification and then hire a experienced contractor or fire protection designer.
