Hi. For methanol tank with diameter of 4 meter and Height 11 meter. Is that no need provide foam pourer system since NPFA 11 stated tank less than 18 meter can use foam monitor? Then what happen when this tank on fire? If using foam monitor only is that need to provide nitrogen blanketing or flame arrestor as well? Or itís better to provide provide foam pourer system inside the tank? Please advise.


Thanks

Thanks
