What issue does using abrasive or grinding sanders without a HEPA attachment present?

Using abrasive or grinding sanders without a HEPA attachment significantly increases the likelihood of lead exposure. When lead-based paint or materials are sanded, small lead dust particles can become airborne. If these particles are not captured effectively, they can be inhaled or settle on surfaces, posing serious health risks, particularly to children and pregnant women.

HEPA (High-Efficiency Particulate Air) filters are designed to capture very small particles, including those that may contain lead dust. Without such an attachment, a standard sanding process can allow hazardous lead dust to escape into the environment, leading to contamination and increased health risks.

This choice underscores the critical importance of taking appropriate precautions and using specialized equipment to minimize lead exposure during renovation or repair activities. The other options do not accurately reflect the health risks associated with lead dust generated by improper sanding techniques.
