agent discharge.
If the developed pressures present a threat to the structural strength of the enclosure, venting shall
be provided to prevent excessive pressures.
8.3 Condensed Aerosol System Agent Supply
8.3.1 Quantity

Primary FirePro Xtinguish condensed aerosol Agent Supply.
The primary condensed aerosol agent supply shall be determined by calculating the required
mass of the solid aerosol forming compound needed to meet the design application density.

Reserve FirePro Xtinguish condensed aerosol Agent Supply.
Where required, a reserve condensed aerosol agent supply shall consist of as many multiples
of the primary agent supply as the authority having jurisdiction considers necessary.
8.4 Design Application Density
8.4.1 Determining Design Application Density
The
FirePro Xtinguish
condensed aerosol extinguishing application density shall be used in
determining the minimum design application density for a particular fuel. For combinations of fuels,
the extinguishment value for the fuel requiring the greatest condensed aerosol design application
density shall be used, unless specific tests are made on the actual mixture.
8.4.2 Fuel Types:

Class B Fuels:
The
extinguishing application density
of
FirePro Xtinguish
condensed aerosol for
Class B
fuels
has been determined by test as per UL 2775.
The
minimum design application density for a Class B fuel hazard
is the extinguishing
application density multiplied by a safety factor of 1.3.

Class A Fuels:
The
extinguishing application density
of
FirePro Xtinguish
condensed aerosol for
Class A
fuels
has been determined by test as per UL 2775.
The
minimum design application density for a Class A Fuels
fire hazard is the extinguishing
application density multiplied by a safety factor of 1.3.

Class C Fuel:
The
minimum design application density
of
FirePro Xtinguish
condensed aerosol for
Class
C hazards
shall be at least that for the Class of fire hazard being protected ‘’’’

Fuel combination:
For combinations of Class A and B fuels the design application density shall be the value for the
fuel requiring the greatest design application density.
