You can work in a room with heavy equipment machinery running all day and night and never get sick or die. Some ventilation is needed of course... but that's like any room... any sealed room will kill u off if ur in there long enough.
I'm sorry, but this conversation is getting to the point of being dangerous to people.
If you run any equipment that burns fossil fuel inside any room of any size anywhere on this planet, it the C02 and Carbon Monoxide will build until it kills or causes harm to every living thing in the building.
If you want to do an experiment, you can get a blood oxygen tester and put it on your finger while you're in this room full of running equipment and watch while your blood oxygen drops to dangerous levels.
Kidney, liver and heart functions will decrease proportionally and cause possible permanent damage to themselves. Cell damage can also result.
Kade, it sounds like someone has filled your ears with a bunch of nonsense man. You can verify everything I've said by calling your local health department and asking. OSHA has very strict limits on running equipment like you've mentioned, indoors UNLESS proper ventilation has been set up. This is because of the inherent danger of doing so.
If you're working in a building with running equipment that has not been vented outside, then whatever business is doing this to you is also killing you nice and slow. Call OSHA on them. That crap will stop right after OSHA shuts them down and fines the hell out of them for damaging your body. You in turn can sue the hell out of them.
There is absolutely NO difference between the poisons given off by different fossil fuel burning machines.
It's dangerous as hell and should NEVER be done indoors for any reason unless proper ventilation is set up. Even then, many people die each year from inhalation of these fumes.
Please, nothing personal about this discussion, but all of your reading this thread need to check with your local health department before you try running anything inside your house or even on a porch. It SHOULD NOT BE DONE FOR ANY REASON, EVER.
