2. Removal of contaminated materials

3. Regular cleaning

4. All of the above

The correct answer is: All of the above

The most effective approach to remediating lead hazards involves a combination of strategies, which is why selecting all methods as a comprehensive solution is key. Each method plays a unique role in addressing lead hazards. Encapsulation is a technique where lead-based paint or other lead-containing materials are covered with a sealant that prevents the lead dust from becoming airborne or otherwise accessible. This method is useful for situations where removal could cause more disturbance and potential risk. Removal of contaminated materials is another critical method, especially when dealing with items like lead-based paint, contaminated soil, or other lead-bearing debris. This approach eliminates the source of lead exposure entirely, thereby reducing risk effectively. Regular cleaning is essential as well; it helps manage and minimize lead dust exposure. Frequent cleaning using specific methods and products helps ensure that any lead dust that may have settled is effectively eliminated. By combining these approaches, the effectiveness of lead hazard remediation is significantly improved, ensuring a safer environment. Thus, considering all these methods together provides a thorough strategy to tackle lead hazards comprehensively.
