the device of 60 °C.
Gases or vapors of explosion groups IIA or IIB.
The cleaning process (spraying of fluids) in the
presence of explosive mixtures with ignition-
sensitive substances in accordance with
Section 2.1 and Section 3.4
is not permitted.
Group IIC gases are NOT permitted during
cleaning.
