Carbon Monoxide Poisoning?
I was posting this in another thread but it had an error before I could post.
Just thought I would check to see if anyone had this problem while running their truck / car / buggy / other.
At the races, bashing, or whatever.
Carbon monoxide is emitted by most combustion engines and especially by nitromethane burning as a monopropellant.
The chemical reaction is: 4 CH3NO2 → 4 CO + 4 H2O + 2 H2 + 2 N2
When nitromethane burns as a monopropellant, carbon monoxide is produced in lieu of carbon dioxide.
The symptoms are: flu-like symptoms, depression, chronic fatigue, chest pain, migraine or other headache, dizziness, confusion, convulsions, or unconsciousness.
Secondary symptoms include: pneumonia, pulmonary edema, hyperglycemia, muscle necrosis, acute renal failure, lesions, vision, hearing problems, respiratory arrest.
Long-term exposure symptoms include: disruption of higher intellectual functions or short-term memory, dementia, irritability, speech problems, blindness, or depression.
In short, have you ever been running your vehicle, started to feel one of the above symptoms, and had to stop because of it?
Or just noticed one of the above symptoms after the fact?
I've done threads about the dangers of racing before and most actual / outright injuries people pointed out were impact-related (ie.
Car crashes into someone).
But I started to wonder how many injuries are poisoning-related, and maybe don't stand out as much as outright injuries since the victim may deal with it themselves, not realise the actual cause, or the symptoms do not develop immediately but anywhere from several hours to a month after.
Any experiences like this?

If you always run your engines in well ventilated or outdoor spaces, it shouldn't be a problem.
When we are outside in urban areas we are always subject to some level of carbon monoxide, mainly from vehicles.
I highly doubt the relatively minute amounts created by a hobby sized engine would be of concern.
You are probably exposed to more carbon monoxide inside a parking garage than out at the track or flying field.

I only run electric RC but where i work now its a large warehouse for car storage and we have Carbon monoxide sensors all over the building as with the cars and vans coming and going it builds up and the sensors let us know whats what,ive had headaches from it before and leave the loading doors up til it clears,but playing with everyone elses nice cars makes the job worth while lol
My forktruck tends to put out alot of emissions too

Just asking for any experiences, that's all.
Gather data first, then draw conclusions, that's what I like to do in cases like this.
|
|
|
Agreed, I didn't mean for it to sound too contrarian
|

Only thing ever happened to me was the gasses burned my eyes.
|
|
|
Yeah that has happened to me as well, the smoke from nitro fuel really irritates the eyes - moreso than gasoline exhaust.

That's probably something else, carbon monoxide is a non-irritant.
And it can't be tasted, smelled, or seen (colorless).
I don't think the carbon monoxide alone can cause any kind of burning sensation.

If you want experience's I'll give you my one and only direct experience.
A couple of years ago the LHS owner got a race together in a indoor arena during the colder weather.
Well by the time the races were over I was getting a very severe headache I was getting dizzy and nauseous.
I had to leave the building at minimum 10 minutes per 1/2 hour cause I just could not stand it in there and I was a smoker at the time.

Interesting topic, all I can report with my nitro's is during close exposure to exhaust for about 30 sec to a min for tuning my truck, my nose would start to sting sharply from the smell.
Other than that I really enjoy the smell ,
Tom.

35 ppm (0.0035%) is a fairly low amount with headache and dizziness occur within six to eight hours of constant exposure .
Basically you would have to be in a sealed building with no ventilation or fresh air coming in running nitro rc cars will take a long time to even get to 35ppm .
I have yet to see an indoor track without some type of ventilation system to remove the gases .
Though it is most unlikely it can very easily happen if proper ventilation and/or fresh air is not brought into the building .

The stinging sensation and smell is probably caused by nitrogen dioxide, not carbon monoxide.
|
|
|
That is why i like nitro so much .

I've run engines down in my basement for years...going back to the early 70's with Cox .049's...
The old fuels we used to use had all castor for oil, and the smell was not all that unpleasant...in fact I kinda like the smell of castor, but the newer synthetic oils and the methanol (along with perhaps rust inhibitors, etc.
) IMO are what's really obnoxious.
The other day I was testing a Picco Maxx .26 running on the "purple cool aid" and the fumes drove me out after only a couple of minutes.
There's a thread similar to this in The Clubhouse...check it out.

Bottom line: Dont run your RCs for a long time inside your garage with the doors closed!

I get these after looking at my wallet after going to the LHS

Funny funny!
yeah you really cant mess around with this stuff- anybody ever read up on what methanol does when its absorbed through your skin?
Yeech!
|
|
1:1 cars are worse.
If you drive to the track with the windows open, I would guess that you are esxposed to more than the couple of hours at a track (in a well ventilated area).

When i drive my nitro trucks for a long period of time like 1 hour per day everyday, my lungs start to have a burning sensation after a week

Are you driving in a building with no or poor ventilation ?

No, i drive in a field but its a half kilometer walk to the field so i turn on my rc car and drive it to the field so as i follow it i guess i breath in loads of the smoke, and also when tuning the engine i accidently sometimes will breath in the smoke which is probably messing up my lungs

I've always run outdoors so no chance of that happening.
I've had my eyes burned a little from those nirtro fumes.
That also happens to be my handle here (Nitro Fumes).

Methanol ingestion?
Much worse when you drink it!
You will embalm yourself as your liver processes it into formaldahyde!

I haven't felt ay of those symptoms but I sometimes get irritated by the accumulation of exhaust in my face.
I don't usually feel anyting unless it's at RCX because the track is indoors.
The carbon monoxide fills up the convention hall causing my stomach to hurt after being there for 5min.

I like the smell it hasnt done any thing to me
