Painting lead bricks with epoxy paint protects surfaces from oxidation and flaking, and minimizes airborne dust during handling.

The ESH group created a team that was assigned to investigate lead brick contamination, develop paint and painting requirements, and evaluate different painting vendors. It was noted that painting the bricks reduces residual lead on outer brick surfaces. Some vendors had a coating that was thicker, less resistant to chipping, and the outer surface contamination was much lower. Having all lead coated or covered bricks in the new facility will prevent the potential spread of lead contamination and will reduce the possibility of ingestion or inhalation by all workers.
