What are the operational requirements to be kept in mind for Foam equipment?

Quality of fire fighting foam produced by Foam equipment depends upon certain factors such as the quality of Foam concentrate, its proper induction in the water stream and mixing of foam solution with air (aeration). As foam equipment is designed for induction and aeration rates at a certain working pressure, it is important to ensure that the equipment is operated at or within the specified pressure range. Operation of the foam equipment at pressure that varies greatly from the working pressure can result in ineffective performance of the equipment (it may also be noted that working pressure normally refers to pressure at the inlet of the equipment, not the line or pump room pressure).

Foam equipment is also designed for use with a specific type of foam concentrate/s. Optimum performance of the equipment can be obtained only when used with recommended foam concentrates.
