    We have a contractor that complains about everything. His newest complaint is that he is having carbon monoxide poisoning from our boom truck even though he is outside and atleast 10 feet from where the exhaust comes out of the vehicle. I definitely want to fix the problem if he really is getting carbon monoxide poisoning. The exhaust on our Mack EM6 truck is released from the bottom of the truck and the boom operating seat seat is on the top of the truck. If the exhaust was released from the top of the vehicle, would that cure the problem?... or make it worse? This is a picture of our truck.

    He is probably not getting "carbon monoxide poisoning" unless he is sitting with his head right next to the exhaust pipe. CO is slightly heavier than air but dissipates quickly in open space. Having said that, diesel exhaust is loaded with carcinogens and is really not healthy stuff to breathe. Rerouting your exhaust to vertical would reduce exposure to people working on the ground, but it looks like the boom operator's seat is right next to where a vertical exhaust would end up. Is this contractor the guy who operates the boom, or just someone you work with? Either way, if you solve this problem he will find something else to complain about. If it were me, I'd try to replace the contractor, not the truck's exhaust.

    He is not getting poisoned he is probably getting a little light headed from the exhaust because your truck is running a little rich. The engine probably has a few miles on her and the injectors slobber and burns some oil.

    So you have a weed burner exhaust on it well that makes the fumes a little stronger for anybody standing on the ground. Then you can't put a stack on the truck or the guy on the crane gets gassed.

    Not much you can do the operator/truck driver is more important than the people standing around the truck.

    Give the guy one of those old army style gas masks :laugh:

    Tell him you have looked into the problem and are implementing a new procedure to ensure his good health.
    Buy 25' of the steel flex exhaust hose and have him attach it to the exhaust each time he uses the truck. Make sure to point it in a safe direction downwind and of course where it can't catch fire to anything.

    Sounds like this guy might be trying to set you and/or his boss up for at best a workers comp claim, and at worst, a lawsuit.

    Read the info about CO poisoning symptoms here:

    And more importantly, about exposure levels and duration here:

    It might be worth your while to look into possibly renting a hand held unit such as:

    You'd have to contact the company regarding rental and/or purchasing info.

    You can rent a single sensor CO monitor with a range of 0 tp 2000 PPM for about 20 bucks. They are very easy to use, and you'll have a reading of basic levels in just a short while.

    What are his symptoms? I've had mild cases twice and can tell you if he's full of it. And it wasn't from a truck exhaust, it was from brush fires and breathing in heavy amounts of smoke for too many hours.:cry:
