What is an example of an Indoor Contaminant Control measure during construction?

Sealing ducts is an important Indoor Contaminant Control measure during construction because it helps to prevent dust, debris, and other contaminants from entering the ductwork. This is crucial because during construction activities, various pollutants can be generated, and if these substances get into the ducts, they can be circulated throughout the building once it is occupied. Proper sealing ensures that the air quality inside the building remains as clean as possible during the construction phase, protecting both the workers on-site and future occupants.

While temporary walls, open windows for ventilation, and exposure to outdoor air can play roles in construction practices, they may not directly address the issue of preserving indoor air quality as effectively as sealing ducts does. Temporary walls can create physical barriers but do not eliminate the potential for contaminants to infiltrate the spaces. Open windows might improve ventilation, but they can also introduce outdoor pollutants into the building. Exposure to outdoor air does not necessarily control the contaminants generated indoors during construction. Thus, sealing ducts focuses specifically on maintaining a cleaner and safer indoor environment by mitigating the risk of contamination.
