Safety instructions and measures

Personal protective equipment

We recommend checking the hazards posed by the process medium being used (e.g. 

u

 GESTIS (CLP) hazardous substance database).

 

Î

Provide protective equipment (e.g. safety gloves, eye protection) appropriate for the pro-
cess medium used.

 

Î

Wear hearing protection when working near the valve.

 

Î

Check with the plant operator for details on further protective equipment.

Revisions and other modifications

Revisions, conversions or other modifications of 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.

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 device by the process medium, the operating 
pressure or by moving parts by taking appropriate precautions. They must observe all haz

-

ard statements, warning and caution notes in these mounting and operating instructions, es-
pecially for installation, start-up and service work.

We also recommend checking the hazards posed by the process medium being used (e.g. 

u

 GESTIS (CLP) hazardous substance database).

 

Î

Observe safety measures for handling the device as well as fire prevention and explosion 

protection measures.

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.

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, the operating personnel must be familiar with the applicable 
health, safety and accident prevention regulations and comply with them.
