2 Section 1 on major IAQ topics. Abbreviated sample forms are included throughout the text so that readers can see what types of informa- tion can be collected using the forms pro- vided in this document. Tab V contains the complete forms discussed in the text. These can be photocopied for use by you and your staff. As you read this document, you will find that some guidance points are repeated. This was intentional, as it allows you to use the sections on prevention, diagnosis, and mitigation as "stand-alone" guides. Tab I: Basics Section 2: Factors Affecting Indoor Air Quality Indoor air quality is not a simple, easily defined concept like a desk or a leaky faucet. It is a constantly changing interac- tion of a complex set of factors. Four of the most important elements involved in the development of indoor air quality problems are: a source of odors or contaminants; a problem with the design or operation of the HVAC system; a pathway between the source and the location of the complaint; and the building occupants. Read Section 2 for an introduction to the factors that influence indoor air quality. A basic understanding of these factors is critical to investigating and resolving IAQ problems. Section 3: Effective Communication An effective communication system helps facility managers, staff, contractors, and occupants to clarify their responsibilities and cooperate in identifying potential IAQ problems. Building occupants can be valuable allies in resolving indoor air qual- ity problems. On the other hand, even small problems can have disruptive and potentially costly consequences if occu- pants become frustrated and mistrustful. Effective communications are the key to cooperative problem-solving. Good communications can be promoted through a group that represents all of the interested parties in the building. Many organizations have health and safety com- mittees that can fill this role. Section 3 suggests ways to work productively with building occupants to prevent IAQ prob- lems and to maintain good communica- tions during IAQ investigations. Tab II: Preventing IAQ Problems Section 4: Developing an IAQ Profile An IAQ profile is a "picture" of building conditions from the perspective of indoor air quality. A review of construction and operating records, combined with an inspection of building conditions, helps to reveal potential indoor air problems and identify building areas that require special attention to prevent problems in the future. Baseline data collected for the IAQ profile can facilitate later investigations, should problems arise. Section 4 suggests a three- stage approach to developing an IAQ profile and describes the products of each stage. Section 5: Managing Buildings for Good IAQ Many indoor air problems can be pre- vented by following common sense recommendations, such as: maintain good sanitation, provide adequate ventilation, and isolate pollutant sources. Other preventive measures may require a careful review of job descriptions, contracts, supplies, and schedules. It is important to designate an IAQ manager to bear respon- sibility for coordinating the effort in your building. Section 5 discusses key elements to include in your IAQ management plan.
