1.3 General safety considerations
The process medium may be hot or otherwise hazardous. Use shields and protective
clothing adequate for the process medium - do not rely on avoiding contact with the
process medium.
Precautions when removing a standard sensor from the process line :
• Check first that the process line is depressurized. Open a vent valve to the atmos-
phere.
• For a prism wash system, close a hand valve for the wash medium and disable the
wash valve.
• Loosen the flange or the clamp cautiously, be prepared to tighten again.
• Ensure you are clear of any possible spillage and you have a clear emergency es-
cape path.
• After removal of the sensor, it may be necessary to mount a blind cover for security
reasons.
