What is a limitation of using plastic bags for paint chip samples?

1. They are too large to transport

2. They generate static electricity

3. They are not durable

4. They are expensive

The correct answer is: They generate static electricity

Using plastic bags for paint chip samples has the limitation of generating static electricity. Static electricity can attract small paint chip particles or other debris to the sides of the bag, which could lead to contamination of the sample or loss of important material needed for analysis. This makes it difficult to obtain an accurate representation of the paint chip composition, which is critical in evaluating lead content. While other options mention size, durability, and cost, they are not as pertinent to the specific challenges faced when collecting and analyzing samples. Plastic bags are typically used because they are lightweight and easily stored; however, the issue of static is a significant factor that affects the integrity of the samples collected.
