大家係月野倉就係聞呢啲野啦.
Most of it, from 65%-75%, is methanol, which is wood alcohol. This is the element that will cause blindness if swallowed. Alcohol has a high viscosity, meaning it evaporates very rapidly and is responsible for MOST of the airborne vapors in nitro fuel. There is very little harm in inhaled methanol vapors unless in concentrated doses. Alcohol is ALSO the most flammable substance in nitro fuel.
Nitromethane is also very poisonous in its pure form, but its viscosity (evaporative rate) is very close to water. What this means is that in it's diluted form - 10-40% in fuels - the amount of airborne nitromethane is very low. Also pure nitromethane is NOT very flammable - you can drop a match in pure ntro and it will most likely go out. Hit it with a hammer, though, and you'll blow yourself into next week.
The rest are synthetic or natural oils for lubrication and there is little to no concentration of them in evaporation.
When burned in an engine, the most dangerous thing you smell or inhale is carbon monoxide, just like real cars. The carbons in the visible smoke are mostly from the oils burning.
So basically if you don't inhale, you could be president. Err, I mean, unless inhaled in concentrated form or for a prolonged time (as in, running it in the garage with all the doors closed,) there is very little harm from nitro fuel in raw or burnt form.
