Page 5: Safety Instructions And Measures
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. - Page 6 Safety instructions and measures Personal protective equipment SAMSON recommends wearing the following protective equipment depending on the pro- cess medium: Î Protective clothing, safety gloves and eye protection in applications with hot, cold and/or corrosive media Î Wear hearing protection when working near the valve. Follow the instructions given by the plant operator.
- 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.
