Controlling Common Indoor Sources

Mouse over the picture above to see messages which are referenced in more detail below.

(Hotspot: Large area over top portion of the picture and covering the exhaust hoods that are visible.)

Remember...“Significant sources of contaminants such as a laboratory bench should be serviced by a hooded exhaust system.”
The hood should be as close to the source as possible. The exhaust hood captures contaminants and draws them efficiently into the exhaust air stream. Workers may also be protected by a Plexiglas shield.
