| HOTEL-HIGH RISE-OFFICE BUILDING |
Each year more than 4,000 American die and more than 25,000 are injured in fires, many of which could be prevented. Property loss is in the billions of dollars, over two million fires were reported last year, over 100 fire fighters lost their lives in the line of duty We have all seen on television or read in newspapers about tragic fires and the destruction they cause to property and families, the skill, dedication, courage and commitment of firefighters is not always enough to prevent such catastrophe.This, as well as other similar tragedies, is a result of there being no adequate and reliable fire-prevention or fire fighting technology available for human occupied facilities.
Hotel, high rise apartments and office building
fires have potential for large loss of life. Although fatal fires
in these properties are less frequent than fatal fires in homes,
the potential for large loss of life is very real. Fires can happen
anywhere at anytime. A fire in a large building creates enormous
risk to everyone. To protect yourself, it is important to understand
the basic characteristics of fire. Fire spreads quickly, there is
no time to gather valuables or make phone calls. In just minutes,
a fire can become life threatening. In five minutes a building can
be engulfed in flames. Heat and smoke from fire can be more dangerous
than the flames. Inhaling the super hot air can sear your lungs.
Fire produces poisonous gases that make you disoriented and drowsy.
Instead of being awakened by a fire, you may fall into a deeper sleep.
Asphyxiation is the leading cause of deaths, exceeding burns by a
three to one ratio.
The breathable, yet fire-preventative atmosphere
of the Resources configuration in escape routes entirely eliminates
any possibilities of ignition or combustion of all common materials.
NITRO GUARD equipment maintains this atmosphere permanently by
constantly ventilating the escape route with fresh hypoxic (reduced
oxygen)
air which is 15% oxygen by volume.
CURRENT fire suppression systems only act when
a fire has already started. It is virtually impossible to provide
an exact concentration
of agent to extinguish fire, while still not be dangerous for
occupants of the area. Breathing in this atmosphere will cause a
significant
increase in the lung ventilation and heart rate. The amount of
CO2 generated by a fire can be as much as 14% by volume, depending
upon fire size and ventilation, so additionally supplied CO2
from using inert gas mixture can produce dangerous levels. Individuals
in normal health may tolerate this but, because of adrenaline
circulating
in the blood; there could be complications for the person on
certain heart medications. In the case of insufficient amounts of
inert
gas suppressant, the combustion will continue under lower oxygen
content, thus resulting in increased release of carbon monoxide
and other intoxicants.
In the presence of artificially increased CO2 people would hyperventilate,
which will cause acute carbon monoxide poisoning even quicker than
without the inert gas agent. Conversely in the case of excessive
inert gas discharge into the human occupied escape route, the oxygen
content would fall lower than 7%, resulting in acute severe hypoxia
which can be lethal itself, especially under the physical and psychological
stress related to the emergency.
These problems could be further complicated because
of the fact that gaseous agents (or particular N2,Argon and CO2 mixture)
is much
denser than air and can accumulate on lower levels where people are
generally trying to breathe to escape. Worst they are lying unconscious
and will be in greater danger of anoxia and suffocation. Increased
breathing and heart rate mean that toxic fire gases are drawn into
the body more intensively and once dissolved in the blood, reach
body tissues rapidly. Worldwide studies show that the majority of
fire fatalities are caused by CO (carbon Monoxide) inhalation.
Experts
agree that fires generate relatively higher proportions of CO when
combustion occurs under oxygen defiant (fuel rich) conditions.
Thus fires suppressed by uncontrolled oxygen reduction, as with
inert gas systems can produce even more CO than fires suppressed
with chemicals
or physical suppressants. Lethal concentrations of CO can go completely
unperceived until it is too late. All of these factors make inert
gas systems applicable only in very limited special types of human-occupied
facilities and the reason to use Resources NITRO GUARD fire prevention
systems EXCLUSIVELY.
