3.2 Special operating conditions for safe use in potentially explosive atmospheres
Maintenance work to be carried out, from chap. 9 (such as refilling the equipment with the filling medium) by
unauthorized personnel may result in damage and lead to loss of approval.
To avoid possible spark generation due to static charge, the device should always be cleaned with a damp cloth.
The legibility of the nameplates must be checked at regular intervals. It must remain legible throughout the entire
period of use of the device. If a reliable reading is no longer given, please contact the manufacturer.
Impacts on the device must be avoided at all costs. Impacts or shocks can produce sparks.
It is the responsibility of the operator to evaluate attached process components or accessories together with the
delivered device by means of an ignition hazard analysis. The operator must recognize the ignition hazards and
prevent them by using appropriate protective measures.
The operator must comply with the points from chapter 2.3"Responsibility of the operator".
