Explosion hazard due to
formation of explosive
atmosphere in the
presence of hot
surfaces during air
supply
Serious injury or death
from burns and / or explo-
sion pressure.
Observe the safety instructions in the operating
manual and follow the instructions for correct air
supply (breaking the vacuum).
The “Manual ventilation” plug (7) must not be
removed while the drying process is still running.
If the drying process has not been completed,
the interior of the chamber must have cooled
down sufficiently before air supply and opening
the door.
Normal operation with
high concentration of
inert gas
Danger of suffocation.
Death by suffocation.
On the chamber side, gassing with inert gas is
automatically interrupted when the ambient
pressure is reached.
Observe the warnings in the Operating Manual
and follow the instructions for installation, tech-
nical ventilation measures, and decommission-
ing.
Respect the relevant regulations for handling
inert gas.
Explosion hazard due to
mechanical spark for-
mation in an explosive
atmosphere by inserting
or removing the slide-in
modules in the presen-
ce of an explosive at-
mosphere
Serious injury or death
from burns and / or explo-
sion pressure.
Observe the warnings in the Operating Manual
and follow the instructions for inserting or remo-
ving the expansion racks.
Explosion hazard due to
mechanical formation in
an explosive atmosphe-
re due to rust
Serious injury or death
from burns and / or explo-
sion pressure.
Observe the warnings in the operating instruc-
tions and follow the instructions for checking the
chamber and expansion racks for corrosion.
Do not use corroded components. Never allow
rust to permeate into the chamber.
1.11 Residual Risks
The unavoidable design features of a chamber, as well as its proper field of application, can also pose
risks for the user, even during correct operation. These residual risks include hazards which, despite the
inherently safe design, existing technical protective equipment, safety precautions and supplementary
protective measures, cannot be ruled out.
Messages on the chamber and in the Operating Manual warn of residual risks. The consequences of
these residual risks and the measures required to prevent them are listed in the Operating Manual. More-
over, the operator must take measures to minimize hazards from unavoidable residual risks. This inclu-
des, in particular the Operator measures described in chap. 2. Residual hazards are to be taken into ac-
count by the operator in their risk assessment.This includes, in particular, issuing operating instructions.
The following list summarizes the hazards against which this Operating Manual and the Service Manual
warn, and specifies protective measures at the appropriate spots (list is not exhaustive):
• Flames, explosion
