Silvara APC1 Fluorine Free Foam Alternative to AFFF/AR
Silvara APC1 fluorine free foam for extinguishing hydrocarbon fuel, polar solvent fuel and solids fires. Silvara APC 1 FF firefighting foam is specially appropiated for indoor fires where the application of foam results in a reduction of oxygen by sweeping away the air to effectively suffocate the fire.
Silvara APC1 can be used for Class A fires (solids) and Class B fires (hydrocarbon fuels and polar solvent fuels) using low expansion devices at concentration of use of 3% with fresh, sea or brackish water and medium expansion at 6%. It can be used with aspirating discharge devices (nozzles, foam chambers,…) with results in higher expansion ratios and longer drainage time.
Silvara APC1 fluorine free fire fighting foam can be easily proportioned using most conventional proportioning equipment such as: balanced pressure pump and bladder tank proportioners, around the pump type and venturis proportioners, and handline nozzles with fixed induction/pickup tubes.
Biodegradability: The theoretical biodegradability is measured with two different tests: BOD (biochemical oxygen demand) over a five day period and COD (chemical oxygen demand). The biodegradability is the ratio of BOD to COD:BOD/COD. A concentrate is considered easily biodegradable when the ratio: BOD/COD is above 0.65. Silvara fire fighting foam products test well above this level and so are easily biodegradable.
