Level transmitter on HP separator

Lessons Identified

During the re-installation of this Level transmitter a check had not been made to ensure that the enclosed tube was sufficiently secure. Given that others have been found it would appear that not all instrument techs are aware of the correct procedure for fitting. Documentation was onboard for this type of transmitter which detailed hazards and fitting procedure, however this was not incorporated with the permit to work, nor were the hazards incorporated within the risk assessment.

Incident Recommendations

Review competency requirements for Instrument Technicians working on devices of this type with threaded connections.
