Page 5: Safety Instructions And Measures
Therefore, operators must ensure that the regulators are only used in operating conditions that meet the specifications used for sizing the devices at the ordering stage. In case operators intend to use the regulators in other applications or conditions than specified, contact SAMSON. SAMSON does not assume any liability for damage resulting from the failure to use the de- vice for its intended purpose or for damage caused by external forces or any other external factors. Î Refer to the technical data and nameplate for limits and fields of application as well as possible uses. - Page 6 Î Wear hearing protection when working near the regulator. 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.
- Page 7 Safety instructions and measures 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. Referenced standards and regulations The regulators comply with the requirements of the European Pressure Equipment Directive 2014/68/EU.
