Safety instructions and measures
Responsibilities of the operator
Operators are responsible for proper use and compliance with the safety regulations. Opera-
tors are obliged to provide these mounting and operating instructions as well as the refer -
enced documents to the operating personnel and to instruct them in proper operation. Fur -
thermore, operators must ensure that operating personnel or third parties are not exposed to
any danger.
Operators are additionally responsible for ensuring that the limits for the product defined in
the technical data are observed. This also applies to the start-up and shutdown procedures.
Start-up and shutdown procedures fall within the scope of the operator's duties and, as such,
are not part of these mounting and operating instructions. SAMSON is unable to make any
statements about these procedures since the operative details (e.g. differential pressures and
temperatures) vary in each individual case and are only known to the operator.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
well as the referenced documents and observe the specified hazard statements, warnings
and caution notes. Furthermore, operating personnel must be familiar with the applicable
health, safety and accident prevention regulations and comply with them.
Referenced standards, directives and regulations
The control valves comply with the requirements of the European Pressure Equipment Direc-
tive 2014/68/EU and the Machinery Directive 2006/42/EC. Valves with a CE marking
have a declaration of conformity which includes information about the applied conformity
assessment procedure. The 'Certificates' section contains this declaration of conformity.
According to the ignition hazard assessment performed in accordance with Clause 5.2 of
ISO 80079-36, the non-electrical control valves do not have their own potential ignition
source even in the rare incident of an operating fault. As a result, they do not fall within the
scope of Directive 2014/34/EU .
Î
For connection to the equipotential bonding system, observe the requirements specified in
Clause 6.4 of EN 60079-14 (VDE 0165-1).
