FIRE SUPPRESSION SYSTEMS PATENTED Electrically Operated Units Features • Significantly more effective than alternative extinguishing agents • Environmentally friendly -Ozone depletion potential (ODP) = 0 - No global warming potential • Ease of installation – no pressure vessels, piping, or expensive installation manpower • Very low maintenance • Provides reliable, cost effective protection for a wide range of fire hazards • Listed for Class A, B, C fires by UL, ULC, CSIRO, ECB, and many others • Favorably reviewed by EPA for SNAP listing • Suitable for enclosed facilities and local applications • Safe for personnel - non-harmful to personnel at design application rates • Safe for valuable equipment -will not harm electronic equipment or magnetic media • Post fire cleanup is minimal - aerosol suspends in air for quick and easy venting after discharge • Compact – up to a 90% reduction in space and weight requirements Applications Due to their fast response time, low fire extinguishing concentration, and environmental safety, Stat-X fire suppression systems may be used in critical applications across a wide range of industries. Aerosol generators are currently protecting and are suitable for use in: - Telecommunications facilities - Flammable liquid storage areas - Process control rooms - Turbine and generator enclosures - PABX rooms - Marine engine rooms and machinery spaces - High value mobile equipment - Power plants - Cellular sites and relay towers - Small boats - Data processing facilities - General industrial hazards Operation /Description Upon detection of a fire, Stat-X generators can be activated either manually or automatically from a suitable listed releasing device. All auxiliary system components (release panel, detection, remote pull stations, etc.) are listed/approved by UL, ULC, FM, New York City MEA, and California State Fire Marshall. Upon activation, the generators produce an exceptionally effective, ultra-fine, potassium based aerosol. Unlike gaseous systems, Stat-X aerosol generators are very cost effective to install and maintain - as they do not require the pressure vessels, piping or expensive installation costs associated with other extinguishing systems. Space and weight requirements are minimal. On an agent weight basis, Stat-X aerosol is ten times more effective than gaseous agent alternatives. The Stat-X generator’s effectiveness is a function of its patented design, aerosol composition, and ultra-fine particle size. Fire suppression is rapidly achieved through interference between the ultra-fine aerosol particulate and the flame’s free radicals – terminating propagation of the fire. Stat-X aerosol generators are virtually maintenance free and have a service life of over 10 years. This, coupled to their very low installation cost, makes them an extremely cost effective fire protection solution.

The service life is determined by the duration of the test, temperature at which the test is conducted, and by the mathematical formula employed by the listing or standard setting body for determining service life. While Stat-X aerosol generators are Listed by UL for a ten (10) year life based on the calculation utilized by UL, they have, in fact, been tested for a period which yields a considerably longer service life when calculated under the formula used by other internationally recognized standards such as ISO and CEN. A description of the different methods follows below: UL Formula (UL 2775): t = A●e-k●T Where: t = Aging duration in days A = a Constant from table 55.1. T = Temperature in OC k = 0.1 * Ln(2) = 0.6393147…{natural logarithm of 2} e = the number ‘e’ {2.718282…} Table 55.1 Useful life, years Constant, A 40,895 59,325 77,755 96,175 Following are selected values based on the above equation.

The equation values are: t = 40895●e-k●TÆ40894·0.003906Æ159.7 days 159.7 days = 10 years Service life according to UL 2775 11503 K-Tel Drive • Minnetonka, MN 55343 Phone: 952.935.9745 • Fax: 952.935.9757 • www.statx.com Other Internationally Recognized Standards (ISO/CEN): The final draft CEN Standard prCEN/TR 15276-1 and final draft ISO Standard ISO/DIS 15779 both utilize a different formula, which is also utilized by ULC with ome modification of T2 (ULC Listing is 12 years). The calculation is as follows: s t2 − = 2ΔT/10 (1) t1 where t 1 = test time, in days t 2 = expected service life, in days Δ T = T1 –T2 T1 = test temperature, in degree Kelvin T2 = equivalent storage temperature, in degree Kelvin Using the CEN/ISO calculation method we get the following result for Stat-X of formula (1) at equivalent storage temperature T2 = 25°C based on the 160 day test previously conducted as part of the Listing process for UL and ULC. T1 = 80OC + 273.15 Æ 353.15K T2 = 25OC + 273.15 Æ 298.15K Then ΔT = 353.15-298.15 Æ 55 Service Life Days = 160●255/10 Æ 7240.78 7240.78 / 365.25 days/year = 19.82 years Service life according to the CEN/ISO Draft Standards. Summary Therefore, where UL or ULC Listing is not a requirement, we can provide the following guidelines for useful service life where a regular schedule of routine inspection and maintenance is conducted over the installed life: Normal Commercial Environments – 15 years Normal Industrial Environments – 12 years Aggressive Environments* – ≤ 10 years *Each aggressive environment must be addressed individually and time to replacement adjusted according to any special circumstances dictated by the environment or anticipated usage. ® ENVIRONMENTAL AND HEALTH ISSUES FOR Stat-X AEROSOL GENERATORS ENVIRONMENTAL ISSUES There are no environmental issues associated with the use of Stat-X aerosol generators. Both the Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) are zero. TOXICITY AND HEALTH ISSUES Aerosol generators do not present a health hazard in their benign state - as the constituent chemicals are pressed into a solid form that is extremely stable - even at elevated operating temperatures. There are no environmental or health hazards from the chemical in storage. Unlike gaseous agents, the aerosol does not decompose in the presence of fire nor does it extinguish by oxygen deprivation. Stat-X suppresses fire (primarily) by chemical interference with the “Fire Propagation” radicals (OH, H, and O) that are essential elements in the expansion of the fire. Stat-X interacts rapidly with these free radicals within the fire zone – thus interrupting the on-going fire reaction. The aerosol, itself, consists of solid and gas combustion products. The solid phase is composed of highly dispersed particles of salts and oxides of alkaline metals that present insignificant health hazards for humans at normal design concentrations. The gas phase may contain small amounts of carbon monoxide CO, carbon dioxide CO2, nitrogen oxides NOx, and ammonia NH3. Production of these gases is minimal in the case of Stat-X due to its patented construction, chemical formulation, and its manufacture in the United States using only technical and reagent grade chemicals. In tests conducted by a certified, accredited testing facility in the United States, Stat-X generators were shown to produce gas levels several orders of magnitude less than the standard allowed for automobile airbag systems for passenger vehicles (See Figure 1). Tests have shown no long-term negative effects from exposure to the aerosol. While the components of the aerosol are not considered toxic at normal concentration levels, ingestion of the ultra-fine particulate may cause short- term discomfort and unnecessary exposure should be avoided. Studies conducted to date, indicate that any potential toxicological issues with the aerosols in general are related to possible elevated levels of potentially harmful products that may be produced in the gas phase – such as, CO, NOx, etc. - and not due to the influence of the solid particulate.1,2 In the case of 1 E.A. Smith, E.C. Kimmel , et al, “Toxological Evaluation of Exposure to Two Formulations of a Pyrotechnically-Generated Aerosol: Range Finding and Multiple Dose”, HOTWC.96 2 “Search of Halon Alternatives in Fire Extinguishing” Safety Problems During Emergency Situations, Issue 1-M, 1992, pages 73-79. ® Stat-X, in particular, The effect is negligible due to the extremely low level of gas production (See Figure 1). In tests conducted by VNIIPO (Russian State Fire Protection Institute), the aerosol was considered to have the same acute toxicity as Halon 13013. The Toxicology Institute of the Public Health and Medical Department of the Russian Federation and tests conducted by the Institute of Biophysics (Department of Public Health and Medicine Russian Federation), as well as others, have shown that the aerosol does not present a health hazard due to limited accidental exposure at normal design concentrations. Exposure to the aerosol is generally of less concern than is exposure to the decomposition products of a fire. Accidental exposures under five minutes are normally considered safe. Certain safety restrictions, however, should always be observed. Exposure to the aerosol should be avoided as ingestion of the ultra- fine particulate may cause short-term discomfort. The discharge of the aerosol also has a relatively high obscuration factor. As a result, the following system installation requirements must be observed. SYSTEM INSTALLATION REQUIREMENTS Stat-X total flood systems shall only be applied in occupied areas in conjunction with a 30 second time delay and system isolate switch to insure egress of personnel prior to system discharge and manual only activation whenever personnel may be present in the protected volume. 3 *Andreev V.A., et al, “Replacement of Halon in Fire Extinguishing Systems”, Proceedings of the Halon Alternatives Technical Working Conference, 1993. ® Stat-X Aerosol Physical Properties Average Values @ 100 gram/m3 Concentration Gas Products: (ppm) Stat-X 15 minute TWA* Automobile- Airbag Emission Standard 20 minute TWA* NIOSH IDLH NO2 1.08 9.90 20.00 NO 0.97 50.10 100.00 NOX = NO + NO2 2.05 60.00 120.00 CO 84.20 445.00 1,200.00 CO2 756.00 40,000.00 40,000.00 NH3 58.30 151.50 300.00 Solid Particulate: Percent K2CO3 55.2% KHCO3 8.2% KNO2 7.9% Other Potassium Compounds 5.5% NH4HCO3 23.2% pH in solution = 8.6 Particle Size Distribution: Percent < 1m 3% < 2m 76% < 5m 97% > 5m 3% Operating and Storage Conditions: Humidity Up to 98% @+35C Temperature - 54C to + 54C Shelf Life 10 years + * TWA = Time Weighted Average Figure 1.0 11503 K-Tel Drive • Minnetonka, MN 55343 Phone: 952.935.9745 • Fax: 952.935.9757 • www.statx.com ® EQUIPMENT EXPOSURE ISSUES FOR Stat-X AEROSOL GENERATORS Stat-X aerosol has been tested on a wide range of materials including structural, aviation composites, and materials commonly used in electronics, and circuit boards. In all cases it has been shown that Stat-X has no deleterious effect on the operating capability of equipment.123 EXTINGUISHING MECHANISM “Fire propagation” radicals (OH, H, and O) are essential elements in the propagation of the fire. Stat-X suppresses the fire (primarily) by chemical interference with these free radicals within the fire zone – thus interrupting the on-going fire reaction. Potassium radicals (K) are the main active component of Stat-X aerosol. They are very active and react with these “propagation radicals” – much like the bromine radicals did in Halons. The chemical reaction may be represented as follows, for example: K + OH = KOH KOH + H = K + H2O K + OH, etc… In addition, the flame propagation radicals recombine on the surface area of the ultra-fine aerosol particulate to further interfere with flame propagation: O + H = OH H + OH = H2O AEROSOL CHARACTERISTICS Due to the ultra-fine particle size and the method of generation, the particulate is quite buoyant and suspends in the gas/air mixture within the protected enclosure. Because of this “buoyant” effect the aerosol does not begin to “settle” for an extended period and, therefore, is extremely easy to vent from the protected area. Only very minor amounts of particulate may be deposited on equipment and, generally, there is no need to do anything beyond extraction of the air within the protected volume through a fan or air handling system – followed by a blow down with compressed air.

Large gaps will exist between particles - leaving no potential for electrical conductivity issues to develop. As a precautionary measure, however, it is always good practice to inspect and clean the site thoroughly following a discharge. While the aerosol itself is quite “clean”, environmental factors are also a consideration. The unknown, and potentially harmful, by-products of an actual fire pose the biggest risk to sensitive electronic equipment. Because unknown products from the fire itself may be present, it is always recommended that equipment be blown down with air or vacuumed following a discharge to insure that no unwanted by- products from the fire itself are present. Unlike HFC’s, which can break down and produce deleterious compounds such as hydrofluoric acid when exposed to the high heat of a fire, Stat-X does not break down when exposed to a fire and quickly extinguishes by means of chemical interference with the flame’s free radicals. Stat-X has been approved by the United States Environmental Agency (EPA) and approved for use under the EPA’s Significant New Alternatives Program (SNAP).4 Stat-X AEROSOL COMPOSITION5 Stat-X aerosol consists of a gas (30%) and solid particulate (70%) mixture. Mean dimensions of aerosol particulate are in the range of 1-2 µm. The aerosol consists of the following, primarily, potassium compounds (% mass 90 seconds after discharge) and carrier gases: Compound: (particulate) % Original Mass Particulate captured within generator housing during discharge/cooling 30.00 K2CO3 22.08 KHCO3 3.280 KNO2 3.160 Other potassium compounds 2.200 NH4HCO3 9.280 Compound: (gas carrier) N2 21.93 H2O 6.550 CO2 1.361 CO 0.097 NH3 0.041 NO 0.001 NO2 0.002 HCN 0.006 Other Trace Total 100.00 4 Authorization letter from US EPA, 2004 5 100 ft3 tank testing of Stat-X Fire Suppressant Units, Talley Defense Systems, 1999 ® SUMMARY Stat-X aerosol has been tested on a wide range of sensitive materials including real world industrial applications. There have been no reports of any negative effects of the aerosol composition on electronic equipment or circuit boards. Properly installed Stat-X systems will not harm electronic equipment and there will be no detrimental affect to the effective life of equipment exposed to Stat-X aerosol. . 11503 K-Tel Drive • Minnetonka, MN 55343 Phone: 952.935.9745 • Fax: 952.935.9757 • www.statx.com
