Wet chemical extinguishing systems are most commonly used to provide fire protection for commercial cooking operations.
They are pre-engineered systems – meaning they are proprietary – which contain predetermined flow rates, nozzle pressures, and quantities of agent required, specific pipe sizes, maximum and minimum pipe lengths, and most importantly are limited to the protection of hazards for which they have been specifically listed. So how does one complete an acceptance test for a pre-engineered wet chemical system once it is installed?
