Exhaust Fume / CO2 Removal

[MESDA6]

My agency is using a retired Horton Ambulance (Ford E350) as a mobile command vehicle and occasionally as a rehab vehicle. One of the issues I'm finding is that while parked on a scene, most of the doors are open more than they are closed, which ultimately brings an excess of diesel exhaust into the compartment. The exhaust pipe is on the curb side which is the near the side door used to access the command area. When a back door or outside compartment is also open, the fumes are circulated through the unit.


I know there are exhaust removal systems powered by a fan for use in stations and ambulance bays, but am not finding a suitable hose to extend the exhaust outlet away from the unit when parked. All of the hoses I am finding state that they must be used with a fan due to the temperature rating of the hose. Anyone know of a suitable hose or exhaust removal system for field use? Typically the unit is parked long term at an incident, so running a temporary hose to extend the exhaust away from the unit shouldn't be a problem. If I can't find a suitable hose, i'm thinking of building some type of portable fixture using an appropriate exhaust connector and double walled chimney pipe to get the exhasqust above the roof line while parked at a scene.


Anyone else had to devise a sloution for this?

Just make a "smoke stack" like on semi trucks that extends above the roofline to whatever height you want and use an exhaust clamp to hold it on when in use, and loosen the clamp to take it off for stowage . Too simple?

This is the idea that popped into my head...

Considered that but may have been over-thinking how it would need to be mounted. The other concern was it being in the way of a compartment door.


Since the original post I found some crushproof flexible hose that looks like it will meet the high temperature requirements. It is specifically rated for desel vehicles being serviced and idling for extended periods. That would be easiest since I can run it out the side, behind the unit or up to the roofline and route it as needed depending on where we are setup. When finished, it will roll up and stow in an exterior compartment.


Thanks for the replies.
