cubic meters (2,000 cubic feet);
    (3) A B-II portable fire extinguisher installed outside the space 
may be substituted for a fixed gas fire extinguishing system in a 
storeroom containing flammable liquids (including liquors of 80 proof or 
higher where liquor is packaged in individual containers of 9.5 liters 
(2.5 gallons) capacity or greater) or a paint locker, with a volume of 
not more that 5.7 cubic meters (200 cubic feet);
    (4) A space which is so open to the atmosphere that a fixed gas fire 
extinguishing system would be ineffective, as determined by the 
cognizant OCMI, is not required to have a fixed gas fire extinguishing 
system; and
    (5) Where the amount of carbon dioxide gas required in a fixed fire 
extinguishing system can be supplied by one portable extinguisher or a 
semiportable extinguisher, such an extinguisher may be used subject to 
the following:
    (i) The cylinder shall be installed in a fixed position outside the 
space protected;
    (ii) The applicator shall be installed in a fixed position so as to 
discharge into the space protected; and

the space protected.
    (c) The following spaces must be equipped with a fire detecting 
system of an approved type that is installed in accordance with

extinguishing system that is capable of automatic discharge upon heat 
detection is installed or when the space is manned:
    (1) A space containing propulsion machinery;
    (2) A space containing an internal combustion engine of more than 50 
hp;
    (3) A space containing an oil fired boiler;
    (4) A space containing machinery powered by gasoline or any other 
fuels having a flash point of 43.3[deg] C (110[deg] F) or lower; and
    (5) A space containing a fuel tank for gasoline or any other fuel 
having a flash point of 43.3[deg] C (110[deg] F) or lower.
