2.2 Responsibility of the operator

EN
The legibility of the marking must be observed during time in use but at least
during inspection periods of three years. If any harm of the legibility is found
please contact the manufacturer to renew the marking.
For the safety of the system, the operator is obliged to carry out an ignition source
and ignition hazard analysis. Refer to chapter 2.3 "Ignition hazards".
The responsibility for classification of zones lies with the plant manager and not
the manufacturer/supplier of the equipment.
