Firepass Corp. has developed a revolutionary fire prevention system called Firepass-P, which prevents ignition of Class A, B, and C fires by generating hypoxic air with oxygen levels between 15-16%. This system poses no respiratory side effects similar to those experienced at moderate altitudes and can be effectively used in sensitive environments such as data centers, archives, and museums. The technology not only enhances fire safety but also helps preserve valuable materials by controlling oxidation and humidity.

2. Phenomenon Discovered!
• Its has long been known that
fire can be prevented or
extinguished by removing
oxygen from the air
• It was not known that at
approximately 16% O2,
new ignition from all
common ignition sources can
be prevented
• It was not previously
understood that at 16% O2
under pressures close to sea
level there was NO side
effects to human respiration
• Tying these three aspects
together, FirePASS Corp.
came up with a radically new
fire protection system.

3. FirePASS-P Prevention System
• FirePASS-P is the first safe system in the
world that can totally prevent ignition of
Class A, B, and C fires.
• FirePASS-P system constantly generates
Hypoxic air containing 15-16%O2 for
continuous ventilation.
• At this oxygen concentration, nearly all
ignition scenarios are prevented.
• In terms of O2 available for respiration, it
is equivalent to being in a passenger plane
or being at a mountain resort without this
discomfort associated with low pressure.

• A schematic comparison of the density of oxygen and nitrogen
molecules in a hypoxic and hypobaric or natural environment at an
altitude of 9,000’ or 2.7 km. (All other atmospheric gases are
disregarded in order to simplify the following explanations).
• Blue circles represent oxygen molecules,
• Green circles represent nitrogen molecules.
21% O2 @ 2.7km 21% O2 @ sea level 15% O2 @ sea level
N2 to O2 ~4:1 N2 to O2 ~4:1 N2 to O2 ~6:1

• Although there is less percentage of O2 in
a FirePASS-P environment, the absolute
amount of oxygen in terms of oxygen
partial pressure is equivalent to moderate
altitude.

32. NFPA Safety Guidelines
According to National Fire Protection Association
(NFPA) Standard 2001, ''Clean Agent Fire
Extinguishing Systems'' p.28. Table A-1-6.1.3
"Physiological Effects for Inert Gas Agents“:
• 12-percent minimum oxygen corresponds to
No Observable Adverse Effect Level (NOAEL)
• 10-percent minimum oxygen shows Low
Observable Adverse Effect Level (LOAEL)

33. FirePASS-P [Safety]
• “Preliminary evidence suggests that working environments
with low oxygen concentrations to a minimum of 13% and
normal barometric pressure do not impose a health hazard,
provided that precautions are observed, comprised of
medical examinations and limitation of exposure”
– Angerer et al. 2002
• Institute and Outpatient Clinic for Occupational and
Environmental Medicine, Ludwig-Maximilians-
University,
• “…in our experiments the effects of hypoxia [on mental
performance] did not seem to be any greater than the
effect of change of environment, motivation, fatigue, or
similar factors.”
– Gustafsson et. al 1997
• Aviation, space and environmental medicine
– Test performed at @ 105mmHg O2 = 13.7 % O2

36. FirePASS for Computer Rooms
and Data Storage Facilities
• Extreme fire risk coupled
with priceless data
• No other solution can
prevent an electrical fire
• Easy set-up and
installation
• Quick turnaround
• Why be reactive when
you can be proactive!

37. FirePASS-P [Applications]
Archives, Museums Etc.
• Protect priceless
historic artifacts and
artwork
• Oxygen reduced
environments will
increase the lifespan of
all materials
• Deterioration is due to
oxidation that, like fire,
can be hindered by
hypoxic atmosphere

38. FirePASS-P [Applications]
Archives, Museums Etc.
• The FirePASS-P system is an environmental
control solution perfect for archives
• With the FirePASS-P system installed, major
decomposition factors can be controlled
– Oxygen
– Humidity
– Formation of H2SO4 (sulphuric acid)
– Formation of HNO2 + HNO3 (nitric acids)
