3-2 | Heated Acid Gas Sample Probe (Large Diameter)

Safety Considerations

Before installing the HAG Probe and powering up its Heater, review

and follow all safety information in this chapter and under “Personnel

and Equipment Safety Information” following the Table of Contents.

This information describes procedures to follow to avoid personal

injury and/or damage to the equipment. All regulatory agency

and personnel safety procedures for your jurisdiction must be

followed.

Take all appropriate safety precautions to prepare for replacing the

existing Sample Valve with a HAG Probe.

This includes obtaining a “hot permit” plus meeting all other safety

requirements, as required by company and hazardous areas safety

policies.

Under normal operating conditions, lethal concentrations of H

S and

other toxic gases from the process duct may be present within the

sample system. The sample system is defined as all components in the

analyzer system through which sample gas passes.

A breathing apparatus must be worn when installing/removing

equipment from the sample gas extraction point. The sample stream is

under positive pressure, and injury or death from inhaling toxic gases

in the sample stream could result from attempting to install/remove

equipment without the use of a breathing apparatus.
