2. Safety
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.
2.2 Responsibility of the operator
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 analysis. The responsibility for classication of zones
lies with the plant operator and not the manufacturer/supplier of the
equipment.
These ignition sources must be taken into account for the instrument:
1. Hot surfaces
The surface of the instrument can heat up due to the temperature of
the process medium. This depends on the installation situation and
must be taken into account by the operator.
2. Mechanically generated sparks
Mechanically generated sparks are a potential ignition source. If the
materials used exceed a total mass percentage of 7.5 % magnesium,
titanium and zirconium, the operator must take appropriate protective
measures.
