Which type of paint removal method is deemed unsafe and restricted?

Power washing within the containment is deemed unsafe and restricted primarily due to the risk of generating lead dust and debris, which can pose serious health hazards to workers and occupants. This method can create a mist of lead-contaminated water, spreading potential contamination beyond the immediate work area and into the surrounding environment. Furthermore, using power washing also risks damaging the substrate beneath the paint, which can lead to more extensive remediation requirements.

In contrast, methods like solvent application, mechanical scraping, and chemical stripping can be performed safely when proper precautions and containment measures are followed. These methods allow for more controlled removal of lead-based paint without the high risks associated with generating airborne particles or widespread contamination within the containment area. Thus, the emphasis on safety and regulatory guidelines makes the restricted use of power washing within containment clear in the context of lead abatement.
