APPLICATION TECHNIQUES FOR PYROCAP B-136™
Using Hose Line
CLASS A APPLICATION
In extinguishing Class A fires the fog setting should be adjusted to the situation.
Typically, a 30 degree setting is appropriate. For most applications, a 3 percent
concentration of PYROCAP B-136™ to water is recommended (3 parts B-136 to 97
parts water).
Firefighters should be aggressive in attacking these fires so that the material
may penetrate into deep seated fires such as tire fires and coal fires. (fig. 2)
Figure 2 – Class A (Tire Fire) Application
CLASS B APPLICATION
In extinguishing Class B fires, a 6 percent concentration of PYROCAP B-
136™ is recommended.
Plunge Method:
The stream should be plunged into the burning liquid at the base of the fire (see
fig 3). Since the turbulence in the burning fluid hastens the emulsifying action, a straight
stream to narrow fog is required. Care needs to be taken to assure that the stream not be
applied in such a manner to cause the agent-in-water to “dive” beneath the fuel. The
nozzle setting may vary depending on the throw distance, nozzle pressure, flow rate,
and angle of approach. Once the fire has been extinguished, the mixture of material and
water should once again be swept to ensure emulsification (fig4).
