Why should lead-painted materials be cut with a chisel rather than a torch?

Why should lead-painted materials be cut with a chisel rather than a torch?

• A. To eliminate the production of dangerous lead fumes caused by high heat
• B. To prevent chopping metal
• C. To reduce waste
• D. To minimize smoke

Answer: (A)

The key idea is protecting yourself from toxic lead fumes. Heating lead-based paint with a torch releases lead into the air as fumes, which are dangerous to inhale. Cutting with a chisel keeps the work cold and avoids heating the paint, so the lead isn’t vaporized. That makes the cold-cut method the safest option, since fumes pose the biggest health risk. The other reasons—reducing waste or minimizing smoke—are secondary and do not address the primary safety concern.
