Environmental Health and Safety (EHS) is committed to working together with facilities,
maintenance, custodial and building occupants to ensure that acceptable indoor air free of
recognized hazards is provided to building occupants. Factors which may contribute to
the quality of indoor air:

• Indoor contaminants such as bacteria and mold, dust, volatile organic compounds,
construction or maintenance activities, ozone from copiers, pesticides, cleaning
chemicals, tobacco smoke, sewer gas, and perfumes and other cosmetics.

• Outdoor contaminants such as exhaust from motor vehicles, fumes from
construction and renovation, outdoor mold and pollen levels, landscape
maintenance activities, and exhaust from adjacent buildings.

The build-up of contaminants is largely influenced by the design, maintenance and
operation of the building heating ventilation and cooling (HVAC) system. An evaluation
of the building HVAC system is an important element of the indoor air quality
investigation where inadequate ventilation is suspected to be causing health related
symptoms. A thorough inspection of the building HVAC system including a review of
the system design, inspection of outside air intakes, fans and distribution systems, review
of building maintenance schedules and controls may be conducted.

Building occupants can also take steps to improve air quality in their workplace. Here
are a few of the recommendations from USEPA:

• Do not block air vents or grilles.
• Comply with the office and building smoking policy.
• Water and maintain office plants properly.
• Dispose of garbage promptly and properly.
• Store food properly.
