4.4 Specific conditions for safe use in accordance with ATEX/IECEx certification
Warning: Process generated electrostatic
The user must address the electrostatic hazards generated from the process of the equipment in accordance
with guidance document IEC/TS 60079-32-1:2013.
Warning: Electrostatically charged liquid
Liquids can become electrostatically charged when they move relative to contacting solids or the spraying of
liquids can also create a highly charged mist or spray. The liquid must be made electrically conductive by
additives or otherwise.
For further information see IEC/TS 60079-32-1:2013 Explosive atmospheres – Part 32-1: Electrostatic hazards,
guidance. With focus on clause 7.1.3, 7.1.4, 7.2.1, 7.2.4.
Warning: Appropriate cleaning fluid
The cleaning fluid should be appropriate for the application (e.g. so no chemical reaction can take place between
the cleaning fluid and the residue of process fluid/powder/compound which can generate heat or a hybrid mixture).
Chemical reactions in Zone 20 - Hybrid mixtures:
End-user must ensure that the cleaning fluid used does not create a hybrid mixture according to IEC
60079-10-1:2015 Annex I.1 in connection with powder / dust residues in the tank in zone 20.
This should ensure that the atmosphere does not change to a classification that lies outside the machine’s
certified scope. When the machine is used for cleaning tanks containing potentially flammable dust atmospheres,
and a potentially flammable fluid is used as the cleaning fluid then an assessment of the hybrid mixture shall be
undertaken by the user, prior to operation.
For further information see IEC 60079-10-1:2015 Explosive atmospheres – Part 10-1: Classification of areas –
Explosive gas atmospheres. With focus on clause 3.6.6 and Annex I – Hybrid mixtures.
Warning: Fluid pressure
The maximum permitted cleaning fluid pressure is 12 bar.
In addition to the above mentioned precautions relating to Directive 2014/34/EU, the Safety Precautions on page 12 must
be observed.
