c. EPA: Please describe the method(s) of activatio n for 1179. If there is a manual activation, what is the time period from activation to discharge? Is any visual or audible warning provided prior to the discharge of 1179? GSL : Upon detection of a fire Firebane ® 1179 is automatically activ ated. The activation to discharge time is less than 20 milliseconds . There is a manual activation lever with a safety pin; after removal of safety pin and activation of lever, there is about 20 milliseconds until discharge. There are no warn ings prior to discharge of 1179, other than the fireball seen milliseconds before discharge. Current gas systems found in military vehicles are harmful to the vehicle’s occupants, thus the reason behind a warning prior to discharge. Harm can be done by pressure, noise level, and temperature of the gas being discharged. Firebane ® 1179 is charged at a pressure 1⁄2 that of gas systems, the noise level is not harmful, and comes out as a liquid. 3. CBI Question EPA: In order to determine whether Firebane will fall under a single or multiple listings, could you clarify whether or not GSL will waive the composition's CBI status? GSL : At this time, the composition of Firebane ® 1179 is a trade secret a nd remains proprietary. Therefore, GSL elects not to waiv e the composition’s CBI status.
