Hello, what kind of fire detectors you will

suggest me to install in two gas stores:

1. Inert gases store (Ar, N), liquid CO2 and O2;

area of the store - 200m2, high - 5,6 m.

2. Dangerous gas store (acetylene)

area of the store - 18m2, high - 4 m.

In dangerous gas store I will put Ex detector

obviously (regarding to class of the room).

What kind? smoke, thermal, flame....?

Thanks for answers.

I think i would be putting ir flame detection in the dangerous gas store as well as opticals with standard spacing. Inert gas would be fine with just opticals. You could store all the inert gas with the dangerous. If there was an explosion at least it would put itself out
