It is important to identify the presence of lead before undertaking renovations, as it can be found in old paints layers. When the paint is disturbed during work, lead can break into chips and generate dust that easily spreads in the air and on surfaces.
This contamination poses a significant risk to occupants, workers, and their families (workers can take lead home with their contaminated clothing). Testing for lead is essential to reduce contamination risks and protect the health of the people potentially exposed during renovations.
