NOTE ON EXPLOSION PROTECTION
According to EN 1127-1:2011, 6.4.2, the max. surface temperature in the container must
not exceed 80% of the ignition temperature of the explosive gas/air mixture or 2/3 of the
ignition temperature of the dust/air mixture (determined in accordance with the latest
version of EN 50281-2-1).
In addition, the smoldering temperature of the dust (ignition temperature of the dust layer
(determined in accordance with the latest version of EN 50281-2-1) must be at least 75 K
above the max. surface temperature. The thickness of the dust layer may reach a
maximum of 5 mm.
Where dust layers of > 5 mm develop, the safety distance between the smoldering
temperature and the maximum surface temperature of the device must be increased.
In this context, the requirements in accordance with the latest version of EN 60079-14
must be observed.
For processes that follow cleaningthe possibly increased surface temperature of the device
must be taken into account.
If necessary, the device must be left to cool down for sufficiently long until a safe temperature is
reached.
Before the start of processes in which potentially explosive mixtures may develop, the device
and/or the ambient temperature in the
container must cool down to a safe temperature that no
longer poses an explosion hazard, see also the note on explosion protection above.
Possible hazards when spraying fluids must also be taken into account and considered in a
separate hazard assessment by the owner.
