This guide is intended as a general guide to the correct use of foams. Specific decisions on when or if foam should be used will depend on the circumstances and conditions of each spill situation.

Polar solvent resistant AFFF can be applied to some water reactive chemicals with a medium expansion foam nozzle to extinguish a fire and to reduce toxic vapor release to the environment.

1. Scope

1.1 This guide restricts itself to addressing the application of foam to water immiscible liquid and some water reactive compounds with boiling points above 15°C for vapor control or fire suppression of land spill or contained spills on water.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For hazard statements, see Section 10.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
