• The majority of the work environment is served by mechanical HVAC systems. These systems are designed to provide a comfortable temperature and humidity range throughout the year. They are also designed to bring in fresh outside air. Fresh air is drawn in and mixed with return air. An equal amount of air is exhausted to the outside. If the fresh outside air is not sufficient, carbon dioxide will accumulate in the building. Carbon dioxide is an indicator for indoor pollutants since it is directly related to the number of people in the building. If carbon dioxide levels are too high there is not enough ventilation air. Sources of indoor air pollution include biological organisms, outgasing from building materials and furnishings, outgasing from cleaning materials, ozone from copy machines, and pesticides. Control of indoor pollutants is two pronged. First, it is important to control and or eliminate the pollutants. Second, it is important to have enough fresh outside air to dilute the remaining pollutants. It is also important to have local exhaust from problem areas like copy machine rooms, areas where solvents are used, and bathrooms (EPA 1990, 1-2).
