Some of the terms may seem foreign to those that don't work in the energy industry so I'll preface this with a little definition section first.
Solar- pronounced many ways. Gas turbine manufacturer. In my world, Solar turbines are connected to gas compressors and generators.
H2S- Colorless, heavier than air, very poisonous gas. Has a rotten egg smell at low concentrations. Kills the sense of smell at higher concentrations. Kills you dead if the concentration is high enough and high enough is very low. Like PPM ranges.
SO2- Sulphur dioxide. Causes acid rain. Byproduct of burning H2S

These are actual conversations that I overheard or had in a control room that I have been working in for the last few weeks. The names haven't been changed because I didn't use names
Conversation #1
<sound of gas venting>
Operator #1: The solar went down
Operator #2: No sh_t? How could you tell

(I love witty sarcasm)
Operator #1: f--- you. What did it go down on?
Solar rep: Looking at his computer- It says fire detected
Everyone looks out the window in the general direction of the turbine. It's not visible from the control room.
Operator #1: walking toward the door, says: I'm going to go start it.
Me: to the Solar rep: Shouldn't we put the f--ng fire out first
There was no fire. A door had been left open and a welder's arc fooled the detection system into thinking there was a fire. The only way to know that is to go look.
Conversation #2
The boiler rep and I were in the control room looking over the control graphic that I had implemented on his boiler.
Boiler guy: Man... that's strong (talking about the distinctive odor of rotten eggs that H2S has)
Me: Yeah... too strong. The wind is coming from the east. Lets ease on out of here.
Me: as we walk out the door . Whoa... that's worse... Lets go north. I'll call an operator
Two operators and a supervisor, with beeping personal monitors (which means H2S is present at some level considered to be important enough to warn them with a beeping sound), walk toward a sump that is just east of the control room. For those that know something about H2S... the sump was due east of them and the wind was from the east. They walked directly to the sump...

They figured out what had caused the problem and solved it.
later that morning...
Me: Well... at least it doesn't stink in here anymore
Operator: as he walked in the door... damn... it still stinks in here.
Above 100ppm or with prolonged exposure to lower levels H2S kills your sense of smell
Me:

Did you guys get the problem fixed?
Operator: Yeah... <checks his monitor> It's not that bad in here. It will clear out eventually. You'll be ok
I felt a lot better after that. Not. It did finally clear. I can smell again. They have a compressor and pump that injects H2S into a well rather than burn it. Someone had left a valve open to the drain system from the compressor scrubbers. That was not a good thing to do. They used to have a sulphur plant but they shut it down. It had issues... The sulphur plant converts the H2S to liquid sulphur. It's not economical to run... just a necessary evil if you don't have re-injection capability.
Conversation #3
Me: Man... that's a lot of SO2 coming out of your flare.
Operator: Yeah. If the wind doesn't switch soon Mr. XXX (guy that lives west of the plant about a mile) is going to get pissed and call again.
Me: Can't say that I would blame him.
Operator: No... that stuff is pretty rank
SO2 is a lot more than just rank
