Examples of Vapor intrusion in a sentence

  • Vapor intrusion can occur in a broad range of land use settings, including residential, commercial, and industrial, and affect buildings with virtually any foundation type (e.g., basement, crawl space(s), or slab on grade).

  • Vapor intrusion can occur in buildings with any foundation type (e.g., basement, crawl space, slab-on-grade).

  • Vapor intrusion is the general term given to migration of hazardous vapors from any subsurface contaminant source, such as contaminated soil or groundwater or contaminated conduit(s), into an overlying building or unoccupied structure via any opening or conduit.

  • Vapor intrusion occurs when chemicals volatilize and migrate from impacted soil and/or groundwater up into a building’s interior space.

  • In optical techniques the wavelength is in the visible or IR spectrum and a source of illumination is used to ’light up’ the target.

  • These potential exposure scenarios include the following: ■ Ingestion, dermal contact, and inhalation (residential receptors and occupational workers); ■ Vapor intrusion to indoor air (residential and occupational receptors); ■ Volatilization to outdoor air (residential and occupational receptors); and ■ Direct contact (excavation worker).

  • Vapor intrusion is a potential human exposure pathway ─ a way that people may come into contact with hazardous vapors while performing day-to-day indoor activities.

  • Reinforcement Steel and Concrete Forms: Vapor intrusion barrier shall be installed before placement of reinforcing steel.

  • Vapor intrusion pathways through utility penetrations and structural openings in floors and walls.

  • Vapor intrusion is defined as the migration of volatile contaminants from the subsurface into overlying buildings.
