4.3.1 SAFETY REGULATIONS
4.3 USE IN AREAS SUBJECT TO EXPLOSION HAZARDS
Only the pneumatic double diaphragm pump in metal (aluminum and stainless steel) and
conductive Acetal can be used in explosion hazard zones. The following safety regulations
must be observed and followed.
Safe handling of WAGNER spray units
Mechanical sparks can form if the unit comes into contact with metal.
In an explosive atmosphere:
Do not knock or push the unit against steel or rusty iron.
Do not drop the unit.
Use only tools that are made of a permitted material.
Ignition temperature of the pumped material
Check that the ignition temperature of the pumped material is higher than the max.
allowable surface temperature.
Medium supporting atomizing
To atomize the material, use only weakly oxidizing gases, e.g. air.
Surface spraying, electrostatic
Do not spray system parts with electrostatic.
Cleaning
If there are deposits on the surfaces, the unit may form electrostatic charges. Flames or
sparks can form if there is a discharge.
Remove deposits from the surfaces to maintain conductivity.
Use only a damp cloth to clean the unit.
