Page 5: Safety Instructions And Measures
Therefore, operators must ensure that the regulator is only used in operating conditions that meet the specifications used for sizing the regulator at the ordering stage. In case operators intend to use the regulator 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 instructions and measures Safety features The Type 33-7 Regulator is a safety excess pressure valve (SEV). When relieved of pressure, the regulator is closed by the force of the positioning springs. Personal protective equipment We recommend checking the hazards posed by the process medium being used (e.g. u GESTIS (CLP) hazardous substances database). Depending on the process medium and/ or the activity, the protective equipment required includes: − Protective clothing, safety gloves and eye protection in applications with hot, cold and/or corrosive media − Wear hearing protection when working near the valve − Hard hat − Safety harness when working at height...
- Page 7 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.

Safety instructions and measures 1.2 Notes on possible personal injury WARNING Risk of personal injury through incorrect operation, use or installation as a result of information on the regulator being illegible. Over time, markings, labels and nameplates on the regulator may become covered with dirt or become illegible in some other way. As a result, hazards may go unno- ticed and the necessary instructions not followed. - Page 10 WARNING Damage to health relating to the REACH regulation. If a SAMSON device contains a substance which is listed as being a substance of very high concern on the candidate list of the REACH regulation, this circumstance is indi- cated on the SAMSON delivery note.
