Risk of explosion due to electrostatic discharge
Electrostatic discharge poses a potential ignition source. Dangerous electrostatic charges can
occur, for example as a result of mechanical friction, flowing air that contains particles - or
persons that are not appropriately grounded, e.g. when carrying out maintenance or cleaning
work.
In an explosive atmosphere, there is a risk of an explosion. This can result in death, serious
injury or material damage.
● Avoid carrying out work specified above on non-metallic parts, e.g. foam rubber for noise
dampeners/attenuators.
● Please comply with ESD protective measures.
2.7 Processes that generate high levels of electrostatic charge
Processes that generate high levels of electrostatic charge
Processes that generate high levels of electrostatic charge, which are far higher than those
generated through manual rubbing, include the following:
● Operation of high-voltage electrodes and ionizers
● Presence of high-speed particles on surfaces, e.g. sprayed charges (electron and ion flows)
in electrostatic coating processes
● Pneumatically conveyed dusts and bulk goods
● Flowing or hydraulically conveyed liquids and drops
● Belts, brushes and foils etc. moved by machines
