of 500 °C (932 °F) are to be expected.
● Keep the extinguishing zone closed in the event of a fire, e.g. do not open any
of the switch or server cabinet doors.
● After a fire, the extinguishing zone is not to be opened by the safety officer until
the danger of re-ignition has subsided.

The release of the system involves sudden noises from the discharged agent
which may surprise persons to the extent that they suffer shock.
● Inform all persons staying close to the extinguishing zone about the existence
of the system and the possibility of its sudden release.
● Make persons familiar with the procedures required in the event of an alarm, a
fire or release of the system.
