Topical Report on a Field Monitoring Study of Homes with Unvented Gas Space Heaters. Volume 2. Protocol for Sample Selection and Measurements

摘要

The report describes the protocol used for an indoor air quality monitoring study of homes with unvented gas space heaters (UVGSHs). The objectives of the field monitoring study are to determine the concentration ranges of carbon monoxide (CO) and nitrogen dioxide (NO2) in such residences and to determine patterns of UVGSH usage in these homes. The protocol addresses the following items: Methods of selecting residences to be surveyed and monitored; Monitoring strategy including three types of monitoring packages; Procedures for deploying monitoring instruments in residences and documentation; Procedures for instrument calibrations and sample analyses; Methods for handling and transforming field data and samples; Quality assurance and quality control provisions. Approximately 176 homes in northern Texas and southern Oklahoma will be monitored. Three types of monitoring packages will be used: 'A' is the most comprehensive monitoring package to be used in 10 percent of homes, 'B' is the intermediate-level monitoring package to be deployed in 20 percent of homes, and 'C' is simplest monitoring package, which will be used in all of the homes. Two sites will be monitored in each home and monitoring will be conducted over 4 to 6 days during January through March 1985.
