Guide for residential indoor air quality investigations.

A Guide for Residential Indoor Air Quality Investigations presents a proposed series of steps that should be followed by trained specialists for identifying and determining the urgency, severity, cause and possible remedial actions needed when a possible indoor air quality problem is reported. It starts with questions that can be given over the phone to occupants and includes steps, questions, and observations for a field visit and a written report, if considered necessary. The Guide is a useful resource for those considering the causes of indoor air quality problems in residences, and can be used to improve an investigato?s understanding of some of the issues and procedures.
