If loss of purge flow creates a significant risk, then the purge flow must
be monitored externally and a response to loss of purge flow must
be provided by the process equipment and interlocked if necessary.
If pyrophoric materials above the Lower Explosive Limit are sent to the pump
then nitrogen should be supplied at a rate to ensure that concentration is
diluted to be below the Lower Explosive Limit, in addition an interlock should
be provided to ensure that gas flow to the pump is stopped when nitrogen
is lost.
