re: What exactly is a plant “operator”?

Kudos to you for keeping the plant running without a safety device!
Write a defeat protocol and have someone monitor the local gauge in the field at all times and report in at an interval that is deemed safe.
It keeps a boiler from tripping and keeps 4 process units from coming down. On those process units are several exchangers that are know leak issues when crossing temperature thresholds (you know, thermal expansion).
So, by stationing an operator to monitor the pressure transmitter you prevent the excursion of unknown amounts of hydrocarbons and one hydrogen fire.
Or yeah, shutdown half an entire site and cause millions of dollars in loss and risk lives because a pressure transmitter loop, that can be verified on 3 different gauges, decided to blow a barrier strip.

It is slightly disturbing that you apparently have a collection of men posing with their trucknuts.
Also impressive I guess.

This is where the frickups really happen. It's this "hold my beer" type of stuff that scares me.

It is impossible to eliminate risk. Automation allows you to reduce risk a lot more than you can with human controls alone. It also encourages operating closer to the edge.
Thinking that automation is infallible gets you into many a frickups as well.

In some instances this is very much the case.

You are scaring the frick out of me. And I'd fire your arse.

Only because you are ignorant of the process and what mitigation can be put in place to prevent catastrophe.

In most cases I am the thing standing between an my boss and/or an engineer wanting to put a piece of automation in bypass. Mainly because they are ignorant of the potential consequences.

By bypassing the purge air pressure indicator (a trip of the boilers) I was able to prevent one fire and a LOPC.
This purge air local gauge is located within arms reach of the ESD and can be monitored.
Also, a true lack of purge air would starve the fire and cause the infrared scanner to trip the heater.

Updated to say purge air pressure indicator and not the purge are itself

Any of you operator baws know of any companies that will be hiring in the beginning of next year? I have a ptech degree and recently started applying. I wasn't able to to get into the field right out of school due to personal stuff, so an internship is not an option for me. Any plants within a 50 mile radius of Baton Rouge is optimal but I'd relocate in a heartbeat.

Keep applying. A lot easier to get into the smaller places.
Honeywell is always hiring.
