First Responder FAQ
The First Responder fire extinguisher is a new and innovative tool designed to aid in the suppression of fires and for use as a personal protection device for fire fighters in emergency egress or entrance situations. It is physically and functionally similar to a smoke grenade — with the major difference that it delivers a highly effective aerosol fire suppression agent — Stat-X.
Typical application scenarios include:
The small size of the First Responder fire extinguisher makes it easily portable.
In the event of a fire, First Responder units are activated by removing the safety clip and pulling the ring pin. The unit can then be thrown near the fire, where it will actuate following a 5 second time delay.
Upon activation, the First Responder fire extinguisher produces an exceptionally effective, ultra-fine, potassium based aerosol that provides extremely fast knockdown and rapid suppression of fires.
On an agent weight basis, Stat-X fire suppression aerosol is significantly more effective than other agent alternatives. It does not reduce the oxygen levels. Fire suppression is achieved through interference between the ultra-fine aerosol particulate and the flame's free radicals — terminating propagation of the fire.
The agent will hang in suspension after delivery providing ongoing suppression capabilities.
Container. The unit housing shall be constructed of metal and incorporate insulating/cooling material. Discharge ports for agent release shall be located around the circumference of the housing. Housing shall accept a M228 initiator and shall be non-pressurized prior to system activation.
Initiator. The initiator shall comply with MIL specification DTL9235210 (modified for output charge) and shall be subject to 100% reliability testing by means of X-Ray.
Safety. Units shall incorporate dual safety devices — a crimped safety pin and safety clip requiring removal prior to pulling the safety pin by means of a ring attachment. The initiator shall incorporate a minimum 4 second delay timer prior to activation
Aerosol Agent. Aerosol generated shall be potassium based and manufacturer shall provide fifteen (15) minute time weighted average data from an independent United States laboratory demonstrating that the aerosol does not produce (at normal design concentrations) harmful levels of CO, CO2, and NOx based on NIOSH standards. Agent shall have no ozone depletion potential and no global warming potential. Agent shall be approved for commercial sale by the US EPA.
Dimensions Unit shall contain 500 grams of aerosol forming composition and shall be 5.625 inches tall (6.875 including initiator mechanism) with a diameter of 3.188 inches. Total unit weight shall be < 2.7 lbs. Origin. Units shall be manufactured in the U.S.A.

Coverage will be dependent on the specific characteristics of the situation encountered — class of fire, level of involvement, areas of potential leakage, etc. Tests have shown significant suppression effects up to an 8 ft high 10ft x 10ft room — around 20 cubic meters. More units would be required for a larger volume or spaces with excessive leakage. The aerosol flows and spreads rapidly throughout the volume, in a manner similar to a gas. However, since the aerosol is buoyant, more may be required in a high ceiling situation.
The First Responder fire extinguisher is most effective when thrown directly at or near the fire.
