TASK FORCE TIPS • 800.348.2686 • www.tft.com

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. Make

sure that:

• Application rate is sufficient (see NFPA 11 or foam manufacturer's

recommendations).

• Enough concentrate is on hand to complete the task (see NFPA for

minimum duration time requirements).

• Foam logistics have been carefully planned. Allow for such things as:

• Storage of foam in a location not exposed to the hazard it protects.

• Personnel, equipment and technique to deliver adequate foam.

• Removal of empty foam containers.

• Keeping clear path to deliver foam as hoses, other equipment and

vehicles are deployed.

Improper use of foam can result in injury or damage to the environment. Follow

foam manufacturer's instructions and fire service training to avoid:

• Using wrong type of foam on a fire, i.e. Class A foam on a Class B fire.

• Mishandling of concentrates, some of which are flammable.

• Plunging foam into pools of burning liquid fuels.

• Causing environmental damage.

• Directing stream at personnel.

There are a wide variety of foam concentrates. Each user is responsible for

verifying that any foam concentrate chosen is suitable for the purpose

intended.
