Work carried out over the last several years has shown
that there can be a significant increase in the amount
of agent required to extinguish and to prevent
re-ignition of fires that are exposed to a continuous,
external, energy source. This has implications
regarding the NFPA 2001 Standard on Clean Agent Fire
Extinguishing Systems, which currently recommends that
in the event of a Class C fire (i.e., fire involving
electrical equipment) the power supply should be
discontinued before or during agent discharge. In
certain critical applications (e.g., remote
telecommunications switching stations) disconnecting
power, however, is neither an option nor desirable. the
current work is aimed at developing a standard test
device and method that will provide data necessary to
address this situation.
