5.2 General fire safety measures

The operator/owner is responsible for following the applicable regulations and direc-
tives for fire safety and to train the personnel for an emergency.
A fire extinguishing system does not relieve the operator/owner from the usual pre-
ventive or defensive measures in case of fires. This applies particularly to the area
around the machine.
Despite all technical protection measures, the possibility of flames coming out
cannot be entirely ruled out. Therefore, there is a residual risk for the personnel at
the machine.
No permanent workstation may be in the vicinity of potential flame exit points on
the machine (e.g., table for cleaning workpieces).
Personnel should avoid being in the vicinity of potential flame exit points as much as
possible.
The following always applies in event of a fire:
• If a warning signal (e.g. signal horn) sounds, leave the danger area immediately;
the personnel must be instructed accordingly for this purpose.
• Access to the area where the fire event took place may only be granted after this
has been approved by an authorized person (e.g. fire safety engineer, fire insur-
ance company, fire department).

The extinguishing effect of CO
centration required for combustion.
There must be a safety area of 10 m
chine, in which the extinguishing gas can disperse after flowing out of the machine.
This corresponds to 60 m 3
and 300 m 3 room volume for a 30 kg CO
Ambient CO concentrations greater than 5% constitute a health hazard.

This must be observed especially if the extinguishing gas is able to flow
into spaces at a lower level.
