Common sense engineers, do you know why the tested with that?

Oxygen level as you go deeper into the excavation

Correct..

I work in safety. In confined spaces we test 4 gases: oxygen, flammable gases, carbon dioxide, and hydrogen sulphide. What he’s doing is unreliable—it only checks oxygen and misses toxic and flammable gas levels. A flame burning does not guarantee safety.

Testing for oxygen presence down there but that's not a good enough test. Most gaseous sulphides are denser than air and settle in depressions.

Oxygen levels or to see if there is flammable gas present, like methane.

So what happens if the fire goes off?

Scaring away if any monsters are down there.

This isn’t rocket science: oxygen levels test if something burns, it’s worth me going down there.

Checking for CO2, don't want those workers to suffocate, heavier gases pool in lower places, which is why exploring mines and caves in winter can be deadly if you don't know what you're doing.

I think he is testing for oxygen levels - its also used by artisinal gold miners, after blasting on re-entry or exploring old shafts, they use a candle, if it goes off it implies no sufficient oxygen. In the absence of proper equipment its does reasonably okay.

Oxygen levels check

Testing for oxygen levels

This test is for oxygen level and presence of explosive gases which is basic in case there is no proper gas meter

Isn't it for oxygen levels in the confined space?

Gotta be something to do with oxygen levels. Fire only burns with oxygen present

To check if it’s same fire in hell

He was taking out the fog with heat

1. Oxygen levels 2. Gas leakages

That excavation qualifies to be a confined space since it’s beyond 1.3M by depth. So initial and continuous gas testing, adequate supervision, well trained workers, effective communication and a proper rescue plan has to be in place as per the job hazard analysis to ensure safety

To check oxygen level. If the fire goes off immediately means it is dangerous for anyone to go down.

idk im retarded

Oxygen levels

What about toxic gases like methane, butane, hydrogen sulfide, carbon monoxide etc?

Oxygen

I'm not an engineer but I have come across the concept of natural gasses pockets such as ethane and methane which are highly flammable. And could be dangerous when they go unnoticed during an excavation

If you understood chemistry very well hutakosa kuelewa

What if the doesn’t goes off because they found crude oil there ?

@grok explain

Air sufficiency

I just know its oxygen related, my low knowledge tells me combustion needs oxygen to happen

Fire needs oxygen

Just use a gas detector. This will not give an actual range of the oxygen levels within the excavated confined space.

To see if its not a portal to hell 😀
