Just another example how the modern education system fails our young people.

This poor fool never heard of sewer gas. The fool jumps in the sewer and is dead within minutes from a lack of oxygen or hydrogen sulfide, ammonia, methane, carbon dioxide, sulfur dioxide, and nitrogen oxides.

Regardless you never go in to a confined space with out testing the atmosphere first. Confined spaces kill a half dozen people or more in this country every year.

i always understood the dangers of Hydrogen Sulfide and agree with you.
Back in the early 50s Southern Bell lost two men at Lenox Ave. CO.(Miami Beach) manholes,. I also believe the Fire Dept. lost at least one man there also.
They enlarged the manhole and added another opening so we could use one for extra air blowers. We were required to run at least two blowers at all times.
All of which brings me to this question: How did “Andy” escape through 500 yards of sewer pipe in the movie “Shawshank Redemption” without dying?
