That gas builds up in sewers. They should have tested the air in the hole. Gas mask won’t work. The gas displaces O2. Forced air or ventilation are the only way to enter safely. They were not trained properly or didn’t think and wanted to save a co-worker, this happens more often than people think. We used retrieval harness rope and a tripod to get our people back but we tested the hole first. RIP it’s a shame.
A Texas exec did a plea deal for a 5-month stretch over a similar mishap. The surviving kids will likely get millions. Poor consolation for losing both parents, but them’s the breaks.
Just saw this on Japanese news. Apparently tests on sulfide were 15 X the legal limit, although only two of the workers reportedly died of inhalation ? Not sure that is possible or the beginning stages of an investigation.
I can still visualize this cartoonish image of Hillary falling through an open manhole. Her huge ass stops her from dropping all the way down but then you hear the sound of it as she pops through. Look out below!
I encounter H2S from time to time as part of my job and am required to wear a monitor to alert me if it is present - it (H2S) is one of, if not THE, most deadly poison gases known to man. Only consolation I could offer these families is that they died very fast, in slightly elevated concentrations you progress from loss of sense of smell to just dead in thr space of a breath or two and never know it.
Hydrogen sulfide control in sewer systems: A critical review of recent progress
Why am I still thinking of a certain scene out of the movie Volcano, though...
4 workers who died after falling in manhole had no protective gear
No PPE?! In Japan?!
Now I'm really wondering if there's something else going on.
Reminds me of a good joke:
A Democrat is walking home in a heavy Democrat neighborhood when he comes across a man jumping up and down on a man-hole cover yelling, “27, 27, 27 ...”.
The Democrat asked the man jumping what he was doing.
The man jumping said it was fun, but you have to try it to really appreciate it.
The Democrat wasn’t in a hurry, so he gave it a try, and started jumping up and down on the man-hole cover yelling, “27, 27, 27 ...”.
Just then, the other man pulled the cover off the manhole and the Democrat fell in. The other man then put the cover back over the manhole, stepped back on the cover and started starting jumping up and down yelling, “28, 28, 28 ...”
