What could be a health hazard during the renovation of an old residential home?

  1. Fiberglass insulation

  2. Formaldehyde in new construction materials

  3. Lead found in old paints and piping

  4. Newly installed vinyl flooring

  5. Aluminum electrical wiring

  6. Modern construction adhesives

The correct answer is: Lead found in old paints and piping

During the renovation of an old residential home, lead found in old paints and piping can pose a significant health hazard. Lead is a toxic substance that can be present in paints used in older homes and in older plumbing systems. Disturbing lead-based paint or pipes during renovation can release lead dust and particles into the air, which can be harmful if inhaled or ingested, especially to children and pregnant women. This is why it is crucial to take precautions, such as proper containment and removal protocols, when dealing with lead-based materials during renovations. Fiberglass insulation, formaldehyde in new construction materials, newly installed vinyl flooring, aluminum electrical wiring, and modern construction adhesives are not typically associated with the same level of health hazards as lead found in old paints and piping during the renovation of an old residential home.
