Page 5: Safety Instructions And Measures
The silencer is designed to operate under exactly defined conditions (e.g. operating pressure, process medium, temperature). Therefore, operators must ensure that the silencer is only used in operating conditions that meet the specifications used for sizing at the ordering stage. In case operators intend to use the silencer 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 − Safety harness when working at height − Safety footwear, ESD (electrostatic discharge) footwear, if necessary 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. Safety features The Type 3381 Silencer does not have any special safety features.
