Safety regulations for the installation site of devices
The risk zoning around the cleaning machine and the possible creation of an explosion protection
document is, in accordance with legal requirements, the operator´s obligation, because this division
is inter alia depending on the solvents used and various conditions such as the ventilation. However,
at this point the operator should be supported with general advice to comply with the obligation.
Helpful advice can also be read at DGUV rule 113-001, DGUV rule 109-010 and also DIN EN 12921-1
and -3.
For example, in many cases the classification of the zones looks like this:
Zone 1
=> The interior of the machine
Zone 2
=> In periphery of 1,0 – 1,5 m
Identify the different zones with appropriate warning and prohibition signs. Marks at the floor can be
helpful. In the area surrounding the unit, open flames and other ignition sources (e.g. welding or
grinding equipment places) are not allowed. Similarly, smoking is prohibited. Temporary work with
ignition must be approved in writing and appropriate additional safety precautions must be adhered
to (remove all combustible materials, classification of a fire station,...).
