One pound of Halon 1301 & FE-36 discharged for every 50 cubic feet
of enclosed volume will achieve a 5% concentration in the air. This is
sufficient to extinguish most fires with a substantial margin of safety.
Stroud Safety systems are designed to achieve the concentration
within ten seconds, where upon combustion cannot occur.
Any size of enclosed area will be protected as long as a 5%
concentration of Halon 1301 or FE-36 is present. Once the agent
is diluted with fresh air to below the 5% concentration, the system
begins to lose its effectiveness.
Halon 1301 & FE-36 has proven effective on the flammable
portions of Class A fires (wood, paper, etc.), Class B fires
(flammable liquids and gases) and Class C fires (electrical). It has
also been found effective on deep-seated Class A fires if sufficient
soaking time is allowed to dissipate the heat.
The DuPont Company concludes that Halon 1301 & FE-36, when
used in concentrations of up to 7% by volume for several minutes,
can be used in the presence of humans with a high degree of
safety. Research has proven that concentrations of up to 7%
by volume of Halon 1301 or Fe-36 produce no harmful lasting
physical effects on humans. However, in concentrations exceeding
7%, tests have shown that subjects experience feelings of lightheadedness
and reduced dexterity. Under normal conditions, the
agent does not have corrosive or other adverse effects on metal
or plastic components.
