Safety instructions and measures
Qualifications of operating personnel
The handwheel must be mounted, started up, serviced, and repaired by fully trained and
qualified personnel only; the accepted industry codes and practices are to be observed. Ac-
cording to these mounting and operating instructions, trained personnel refers to individuals
who are able to judge the work they are assigned to and recognize possible hazards due to
their specialized training, their knowledge and experience as well as their knowledge of the
applicable standards.
Personal protective equipment
We recommend wearing the following protective equipment:
−
Safety gloves due to the moving parts (actuator stem, threaded rod, plug stem, hand-
wheel)
Î
Check with the plant operator for details on further protective equipment.
Revisions and other modifications
Revisions, conversions or other modifications to the product are not authorized by SAMSON.
They are performed at the user's own risk and may lead to safety hazards, for example. Fur-
thermore, the product may no longer meet the requirements for its intended use.
Safety devices
The side-mounted handwheel is locked by a locking bolt, which locks the gear, to prevent ac-
cidental adjustment of the valve travel (see Fig. 7 and section 6.1).
Warning against residual hazards
To avoid personal injury or property damage, plant operators and operating personnel must
prevent hazards that could be caused in the handwheel by the signal pressure or moving
parts by taking appropriate precautions. They must observe all hazard statements, warning
and caution notes in these mounting and operating instructions, especially for installation,
start-up, and service work.
Responsibilities of the operator
The operator is responsible for proper operation and compliance with the safety regulations.
Operators are obliged to provide these mounting and operating instructions as well as the
referenced documents to the operating personnel and to instruct them in proper operation.
Furthermore, the operator must ensure that operating personnel or third persons are not ex-
posed to any danger.
