One of the “joys” of working in a large, old, poorly maintained and shrinking chemical plant is the constant barrage of dangerous chemical smells. I used to walk from the parking lot to the entrance under a pipe bridge that carried a bunch of pipes, one of which was labelled “Ketone”. There was often a strong smell of aromatic hydrocarbons under that bridge.
Today, just after I’d posted my previous posting, three company firemen were standing in front of my cube, wearing breathing tanks on their backs (but thankfully not using them). One of my co-workers came by and said he’d reported a nasty smell and something dripping onto his desk from the ceiling above, and they’d come out.
