Fumes(particulates/aerosols)
-Produced when metals are heawed (>2000 องศา) to the point they become a vapor or gas.
-The hot gas cools once airborne, then condenses to form small particles.
-Diameter : 0.1-100 ไมโครเมตร
-Processes : welding, cutting torch,sometimes buffing/grindind.
-CO is not a fume : airborne phase is a gas.
-Gasoline is not a fume : airborne phase is a vapor.
