Why is moisture control important in lead hazard management?

Moisture control is crucial in lead hazard management because moisture can lead to the deterioration of lead-based paint. When paint becomes wet or is exposed to high humidity, it can break down more rapidly, causing it to peel, crack, or blister. This deterioration creates lead dust and chips that pose significant health risks, especially to children and pregnant women. Lead dust is a primary pathway for lead exposure, as it can be inhaled or ingested.

Maintaining proper moisture levels in environments where lead-based paint exists helps prevent the formation of lead dust and the subsequent health hazards associated with it. Effective moisture management ensures that painted surfaces remain intact, thereby reducing the likelihood of lead exposure from deteriorating paint.
