Controlling Common Indoor Sources

(Hot Spot on area covering the pollution and the exhaust)

Remember...“Stationary sources of pollution should be exhausted directly to the outdoors . The source of pollution should be located close to the exhaust and arranged so that occupants and the exhaust are on opposite sides of the source.”
Ideally, for significant sources, the exhaust should be directly connected to the source, or have an exhaust hood immediately above where the contaminants exit the source, as with a kitchen range hood.
Copy machines produce both excess heat and air pollutants. Thus, an efficient exhaust system will draw both heat and contaminants out the exhaust and therefore save energy while improving indoor environmental conditions. Though seldom used, exhaust systems attached directly to the copier are available from manufacturers.
Where the ideal is not practical, make sure that people are not be located in the path of the air as it moves from the source toward the exhaust, and the path should be as short as possible. In this picture, the exhaust is behind the copy machine and draws contaminants away from the user.
