Hello all:
This exact question came across my mind the other day while running my Atlantic with the smoke on. I use proto-smoke for my engines and MTH claims that the vapor is harmless to the body. Obviously intake of the liquid form would cause damage but is smoke fluid vapor really more hazardous to ourselves than manufacturer's claim? I have heard many stories about people getting "smoked out of the room" due to the engine's level of smoke output. I don't get bothered by the smoke fluid vapor at all but my parents take exception to it when it is on.
Also, does smoke fluid vapor affect people with asthma? I don't have asthma but if someone does their opinion on this matter would be appreciated.
I am not trying to say that smoke fluid vapor can cause black lung and other various forms of lung diseases but can excessive amounts of smoke fluid vapor in confined spaces with less ventilation cause problems?
I am curious to see what you think.
