This is one of the most popular fire suppression systems adopted for high value equipment / goods, such as historical artifacts & sensitive electronic equipment. Since the most popular type of Clean Agent Suppression is Total Flooding System and this type of system’s key performance is highly dependent on the enclosure integrity (i.e. holding period after discharge), such that the examine and test of room integrity leakage in terms of quantitative results shall be obtained and recorded.

This presentation will introduce the recent development and control of different suppression agents, key parameters for total flooding system design and share cases that fail to pass the room integrity test and suggested solutions to fulfill the holding period.
