Kelly Air Force Base
The paint shop in Bldg. 329 used a conventional method of hand cleaning paint guns. Wastes were collected in buckets and disposed of as hazardous waste. Totally enclosed paint gun washers were implemented in place of hand cleaning the paint guns.
Paint guns are connected to wash lines and placed in the washer where MEK is circulated through the gun. MEK is re-used after paint waste is filtered out.
This project reduced MEK (an EPA 17 ITP chemical) use in the paint shop by more than 500 gallons per year.
