Transmission of SARS-CoV-2 has been the subject of considerable debate throughout the pandemic… (WHO, Apr 2024)
(4 RC) - The former Delfasco Forge facility is in Grand Prairie, Dallas County, Texas. The facility operated as a munitions manufacturing and forging facility from 1980 to 1998. Former facility operations used chlorinated solvents containing trichloroethylene (TCE) and other chemicals to degrease metal. These operations contaminated on-site soil and groundwater. The groundwater contamination has spread to the adjacent residential area where an estimated 157 occupied homes… (CDC ATSDR, Apr 2024)
(4 RC) - The WHO air quality guidelines set goals for protecting public health on a worldwide scale. They were established through a rigorous process of revision and evaluation of scientific evidence on the health effects of air pollutants and, like other WHO guidelines, are not legally binding recommendations … (WHO Global AQG, 2021)
(2 RC) - This paper covers the specific topics of: A. How cleaning reduces HVAC energy consumption. B. How energy consumption can be calculated with pre‐cleaning and post‐cleaning measurements. C. Mechanical and other issues within HVAC systems that contractors encounter while inspecting and/or cleaning that can be reported and corrected to maximize HVAC energy efficiency… (NADCA, Nov 2016)
(4 RC) - This database includes laws that address a wide range of pollutants, practices and building types. The purpose of the database is not to indicate how many IAQ laws exist, but rather to provide examples of various types of policy strategies that states have employed. The following are general guidelines used to develop the database… (ELI, 2022)
(4 RC) - EPA regularly receives partner questions and comments regarding various aspects of the Indoor airPLUS program requirements. This Policy Record format will be used to provide regular updates on the resolution of future issues, including changes to program requirements and clarifications or refinements to the specifications. The primary purpose of this document is to allow stakeholders equal access to the latest policy issues and resolutions. This document also serves as an official program update… (EPA, Dec 2021)
(.50 RC) - The Low-Emission Materials requirements address composite wood products, interior paints and finishes, and carpets and carpet adhesives used in the construction of Indoor airPLUS qualified homes. Products meeting the referenced standards are generally widely available in the market. This document is intended to help builders, designers, and Raters identify and locate compliant products… (EPA, Oct 2015)
(1 RC) - These specifications were developed by the U.S. Environmental Protection Agency to recognize new homes equipped with a comprehensive set of Indoor Air Quality features. They were developed with significant input from stakeholders, based on best available science and information about risks associated with IAQ problems, and balanced with practical issues of cost, builder production process compatibility, and verifiability… (EPA, Feb 2008)
This HHE conducted by the CDC and NIOSH explores the ventilation system at Blue Cross and Blue Shield of MI in Grand Rapids MI. Workers at the auto industry were experiencing flu like symptoms which they believed were due to inadequate air ducts.
(.50 RC) - The National Institute for Occupational Safety and Health (NIOSH) has conducted several Health Hazard Evaluations [NIOSH 2019] in workplaces with reported health concerns associated with construction and renovation in occupied buildings. During these evaluations, NIOSH investigators identified issues that could affect indoor environmental quality such as a lack of dust control, the use of high emission building materials…(NIOSH, Jan 2020)
(4 RC) - Possible exposure pathways associated with this site include inhalation of contaminated indoor air as well as dermal exposure to and incidental ingestion of contaminated soil, sediment, and surface water. The indoor air pathway was selected for evaluation first because of the potential for nearby residents to be exposed to volatile chemicals in their homes throughout the year… (ATSDR, Sept 2014)
(2 RC) - A soil gas data screening indicates that 1,4 dioxane is a concern for vapor intrusion in a WI building occupied by workers and children. As 1,4dioxane is highly soluble in water, it is possible that its presence in soil gas samples indicates the leading edge of the groundwater plume may be approaching the building. A complete indoor air investigation of the WI is necessary to evaluate the potential for current exposures… (ASTDR)
(1 RC) - Secondhand cannabis smoke, like secondhand tobacco smoke, creates unhealthy indoor air quality. Ventilation and engineering techniques cannot reduce this pollution to healthy levels, and complete smoke-free policies are the only way to provide healthy indoor environments.
