Firefighting Foam RFC-105
Synthetic foam concentrate with good wetting properties, specially formulated to obtain foams for fighting “class A” fires.
RFC-105 is a synthetic foam concentrate with good wetting properties; specially formulated to obtain foams for fighting “class
A” fires (forest, urban, structural, etc.) that can also be used effectively in combat for “Class B” fires (hydrocarbons).
It can be used with low, medium and high expansion foam equipment, with not aspirating equipment (water spray nozzles, sprinklers,
etc.) and CAFS (Compressed air systems). When used in “Class A” fires, foam adheres well to the material and the fluid drained from the foam, with good wetting properties, penetrates into the substrate preventing a possible reignition.
When used to fight class B fires can be applied with low and medium expansion nozzles. In low expansion, it is advisable to use gentle application. It is particularly interesting the use of RFC-105 with compressed air foam systems (CAFS) in class A and class B fires, where its high efficiency reduces the water consumption.
RFC-105 nominal proportioning rate is 0.5% in fresh or sea water. This rate can be varied between 0.2 and 1.0%, depending on the type of foam desired. High concentrations (1%) are recommended for high expansion foams and when slow drainage times are desired. Having such a low viscosity, the concentrate dissolves very quickly in water, nearly without agitation.
RFC-105 is highly biodegradable.
The foam concentrate shall be stored at temperatures between -10° and +50°C, preferably in their original containers, sealed. The product does not have expiry date.
Foams should not be used in contact with electrical equipment, neither with chemical products that can react with water. It is recommended to avoid the contact of the foam concentrate with the skin. In case of eye splashes wash with plenty of water. In case of ingestion do not induce vomit, drink water and take medical advice.
