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.
