Developing an IAQ Profile 23 information about normal operating conditions or identify problem locations. If you begin to suspect that underventila- tion is a consistent problem, you may decide that it would be helpful to obtain more ventilation monitoring equipment. (See Appendix A for further discussion of carbon dioxide and other ventilation measurements.) Talk with staff and other occupants A walkthrough inspection provides an opportunity to introduce facility staff and other building occupants to the topic of indoor air quality and to understand current staff (and contractor) responsibilities in relation to housekeeping and maintenance activities. Advance notice of the inspec- tion will make it seem less intrusive and may encourage staff and other occupants to remember important information. Discussion of routine activities in the building will help to clarify elements that should be included in the IAQ manage- ment plan. Ask staff members about their job responsibilities, training and experi- ence. It will be helpful to meet with responsible staff and contractors to discuss: Facility operation and maintenance (e.g., HVAC, plumbing, electric, interior maintenance) ■ HVAC operating schedule (e.g., occu- pied/unoccupied cycles) ■ HVAC maintenance schedule (e.g., filter changes, drain pan maintenance) ■ use and storage of chemicals ■ schedule of shipping and receiving, handling of vehicles at loading dock ■ scheduling and other procedures for isolating odors, dust, and emissions from painting, roof repair, and other contami- nant-producing activities ■ budgeting (i.e., how do staff members influence budget decisions?) Housekeeping ■ cleaning schedule ■ trash storage and schedule of refuse removal ■ use and storage of chemicals Pest control ■ schedule and location of pesticide applications ■ use and storage of chemicals ■ pest control activities other than use of pesticides Look for IAQ problem indicators The walkthrough inspection can be used to identify areas with a high potential for IAQ problems. The following are general indicators of IAQ problems: ■ odors ■ dirty or unsanitary conditions (e.g., excessive dust) ■ visible fungal growth or moldy odors (often associated with problem of too much moisture) ■ sanitary conditions at equipment such as drain pans and cooling towers Maintenance is more likely to be performed on a routine basis when there is good access to HVAC equipment such as that shown in this photo.
