Nice English.
How can I answer best your industry of chemical gas and fire question divide zoning?
Sorry. I couldn't resist.
Seriously speaking...
Fire and gas detection are two different things. Fire detection can be accomplished with smoke or heat detection. Linear heat detection may work well depending on your application. If ultra-quick responses are impertative, than infrared or ultraviolet based flame detection may be in order.
Gas detection is accomplished by using catalytic bead sensors either high in the room or low along the floor depending on if the gases you are trying to detect are lighter or heavier than air. Spacing of the detection should pay attention to the storage, but manufacturer's recommendations should be followed. One thing for sure, it's not every 130 sq. in. (that would be 1 detector every foot!) I don't think you need quite that many!

for a chemical industry I think you should install one detector over every 130 square inch
