Novec1230 (3M) Fluorinated ketone FirePro Advanced Condensed
Aerosol
 
Classification &
Standard
Clean extinguishing agent
NFPA2001
ISO14520
Condensed Aerosols
NFPA 2010
ISO 15779
Space Occupied & Unoccupied Occupied (a) & Unoccupied
Safety to humans Highest Safety Margin
Remarks:

-Novec 1230 has LOAEL of >10% but at the same
time has a LC50 also at >10% (j)
- When Novec 1230 is inhaled and crosses the lung
air-water interface, can hydrolyse (react with water)
and produce Perfluoropropionic acid (k) (l) (g).
Perfluoropropionic acid is known as strong acid,
which attacks steel, forming iron salt (Ferric &
Ferrous). According to its MSDS, it may cause eye
and skin burns, severe & permanent damage to
digestive tract. Also it's known as tumor promoter (a
carcinogenesis process) and peroxisome proliferator
(liver damage). Peroxisome proliferation in liver has
been observed at LOAEL = 0.0997% (l)
- At high temperatures Novec 1230 decomposes to
produce COF2 (carbon monoxide di fluoride or
carbonyl fluoride) and HF (hydrogen fluoride). COF2
has a Chemical Abstracts Service (CAS) Reg NO. 353-
50-4, which is highly toxic to humans and causes
serious Lung Damage with a delayed effect (see
attached internet info). HF is a very strong acid with
possible hazardous effects for humans and
equipment (n)(o)
- High pressure cylinders (25, 42 bar) pose a hazard
to operating or maintenance personnel
Non toxic
(b) (c) (d)
FirePro Condensed Aerosol
consists of K
2CO3 in suspension in
N
2, CO2 and H2O.
K
2CO3 (Potassium Carbonate) is
the active extinguishing Agent.
Does not react with water. It is
soluble in water and the resulted
pH is slightly alkaline.
No effects on human health are
expected when humans are in
contact with low concentrations or
amounts of the substance.
The substance is neutralised in the
environment and therefore it is
not persistent. Furthermore it
does not accumulate in organisms.
(q)
Residues No (gas)
Remarks:
No solid residues but, due to thermal
decomposition, liquid residues of a HF solution
Residues are minute (1-5 microns),
easy to remove and non-corrosive
to electronics (e)
Heat Generation No heat generation
Remarks:
Sudden temperature drop caused by discharge may
cause thermal shock to sensitive equipment
FirePro Condensed aerosol utilizes
natural ceramic coolant. Stream
temperatures are determined (f)
10min hold time
(NFPA)
Guaranteed with every system
Remarks:
Design very dependent on enclosure integrity
significant leakage will cause system to fail. Also,
pressure vents must be provided as negative peak
pressure of -800 Pa may be created within the
enclosure at discharge
FirePro is a non-pressurised agent.
10 min. hold time is ensured in
non.-tight enclosures. No door-fan
test required (d)
Visibility May form fog for short time if room temperature
below dew point
Reduced visibility
Critical
Applications
Yes
Clean. Leaves no particles.
Approved for critical applications.
Typical applications:
Computer rooms, Data storage,
Switchgear, Servers,
Telecommunication, Electronics.
Specified by major power utilities.
Remarks:
Possible decomposition of Novec 1230 to produce
HF which is can be corrosive.
Yes
Particles in the size of 1-5 μm,
non-corrosive, no damage to
electronics (e), no restrictions
(NFPA 2010), typical applications:
control rooms, data storage,
switchgear, servers,
telecommunication, electronics,
specified by major power utilities
(h)
Risk of
Conductivity
No No
Tested for up to 75 kV and
installed in HV applications up to
132 kV (i)
Risk of Corrosion No(8)
Remarks: Hydrogen Fluoride (HF) which can be
potentially produced as a result of decomposition of
Novec 1230 is highly corrosive- acid (p).
No (e)
Tested on electronics by
accredited Institutes.
Chemical
Reactivity
High (reacts with water, alcohols, amines) (g) Low Chemical reactivity. FirePro
Condensed Aerosol consists of
K
2CO3 in suspension in N2, CO2 and
H
2O. K2CO3 is stable, non-reactive
and slightly alkaline
Storage Contact with water or solvents, either polar or
hydrocarbon, could render Novec 1230 fluid
ineffective (m)
FirePro generators are not
pressurised and they can be stored
under normal conditions without
deterioration of their
performance.
Chemical
Decomposition
- At high temperatures Novec 1230 decomposes to
produce COF2 (carbon monoxide di fluoride or
carbonyl fluoride) and HF (hydrogen fluoride). COF2
has a Chemical Abstracts Service (CAS) Reg NO. 353-
50-4, which is highly toxic to humans and causes
serious Lung Damage with a delayed effect (see
attached internet info). HF is a very strong acid with
possible hazardous effects for humans and
equipment (n)(o)
FirePro patented FPC compound
produces upon activation
atmosphere gases (N
2, CO2 and
H
2O) and K2CO3. The products of
the extinguishing action are the
same.
