Most quality foam products will retain their effectiveness for years under ideal
conditions. But a number of "real world" factors can cause foam
concentrates tolose
their extinguishing efficiency.
One common problems is water entering a foam storage tank due to a leak or
system malfunction. If this should happen, your may unknowingly apply foam
during an emergency situation that is too diluted to effectively mitigate the
hazard.
Another problem is foam concentrate that has thickened during storage, due to
evaporation or contamination. This can cause the foam to proportion incorrectly
or even plug lines and equipment. And it is not uncommon to find tanks that
have been filled with incompatible foam products, which can cause the resulting
mixture to be unusable.
Because of these and countless other factors, it's important to test your foam
inventory annually, to make sure it will perform to the manufacturer's specs.
Dyne Technologies' annual foam testing/reminder service is an easy, convenient
way to help ensure that your facility is fully protected.
