Small center, about 40 routes. I work up by unload. Two of us are Designated Responders. 1/2 way through preload, everyone smelled propane on the belt closet to the propane fill-up station. My experience with propane, is if it's leaking, it's just gonna form an ice blob. The feeder unloaders never mentioned a smell, and there was no package anyone could point out, so I really believed that it was the station or a truck, neither of which are packages. Seemed more like a management issue to me. Belt sup did nothing, everyone kept crying. I told them to man up and shut the belt off and leave the area then. They kept working and crying. Another sup came up, I asked if they were servicing the station or something. Sup said "I don't know, I'll go see" which meant "I'm in a Xanax haze so I'm just gonna wander off." Finally one of the belt preloaders went to the office and the same sup just rolled her eyes at her. The preloader left the office and 2 FT on road sups were there, one of which is DR qualified. They went down, sniffed out the truck, and started it up and everything was fine. It was 95 here yesterday, 55 this morning, first cool day in 7 months. I know gasses do funny things when the weather changes. My question is, as a DR, should I have been everyone's mom, and the manager, and took total charge of the situation, only to get totally reamed later for doing that and killing production? Some of us had a little union meeting in the parking lot (minus the beer), and that's what I said. That they need to stand up for themselves, they should have shut the belt off and went outside. I don't want to be the bad guy all the time. I'm the only one who files grievances on my sort. On a side note, that same belt sup came and got me once, saying a driver must have stepped in some dog doo and the truck really stinks, and that's hazardous. All I did was look at her and perfect my 30 second blank stare til she went away.
