Cleanup: In-Cabin Fire Extinguisher Mishap

I've been keeping my in-cabin

$138 Amerex B500 , 5lb ABC Dry Chemical Class A B C Fire Extinguisher (2)

Amerex B500 fire extinguisher (chemical powder) in the pocket in the driver's side suicide door of my access cab, along with a medical kit. Unfortunately, the pin preventing the fire extinguisher for being used apparently wiggled out, which I discovered when my sleeping bag fell onto the handle and depressed it for about ten seconds earlier this evening. Since the extinguisher nozzle was pointed down, almost all of the powder ended up in the pocket, inside the door, and in the rear portion of the plastic-covered electronics wiring channel along the door. I've so far cleaned everything down to the best of my ability with a damp rag (including pulling the the wiring channel cover off and cleaning around it - it looks like the powder got caught on the lip and never entered the area actually containing the wires) and shook out the door to the point where I think most of the powder is out. I plan on taking the door apart and double-checking the wiring channel tomorrow under better lighting conditions. Aside from vacuuming it out and cleaning with a damp rag, is there anything I should be particularly concerned about or should do for cleanup of the powder? Thank you.

 

Had little bigger mishap when rented a paint booth and lot boy pressed the fire alarm instead of compressor start . Reversed truck into paint booth and heard alarm .Then saw dark cloud coming down .Got back in drove out but powder already got in truck .Blew out interior with air then wiped down interior .
Seems like you pretty much got it all . Lucky for you most got caught in door pocket . Maybe if you got compressor just blow out interior .

 

I had a similar issue and set one off in the bed. Stuff hosed right off.

 

I’ve done this before as well. Been cleaning it up for the last 8 years. Just did a sound deadening project and had the interior stripped out 100%. I might have finally rid myself of the last couple of ounces.

 

ABC (Monoammonium phosphate) dry chemical is corrosive to certain metals and electronics. It is not recommended for use around aircraft for that reason.

Clean up procedures from one manufacturer.

Wish I woulda held on to a couple of old Halon extinguishers for just this reason.
