1.4 Danger from Process
It is possible that the sensors are installed in ducting containing process particulate that is a
hazard to health. This may take one or more of the following forms:
• Particulate which is inflammable or explosive
• Particulate which is toxic or in some other way a hazard to health
• Particulate contained within high temperature gas
Unless the process conditions are known to be entirely safe, suitable precautions such as the use
of breathing apparatus or duct purging/detoxifying must be employed before any entry is made
into the duct for installation or maintenance purposes. If in doubt, consult the local Safety Officer
and/or local Safety procedures.
