--- FLOW EXCEEDS RATING OF BLITZFORCE PORTABLE MONITOR
For Class B fires, lack of foam or interruption in the foam stream can cause a break in the foam
blanket and greatly increase the risk of injury or death. Follow procedures established by the AHJ
for the specific fuel and conditions.
Improper use of foam or using the wrong type of foam can result in illness, injury, or damage to the
environment. Follow foam manufacturer's instructions and fire service training as directed by the
AHJ.
