Which statement best describes encapsulant?

Which statement best describes encapsulant?

• A. A barrier that uses a solid material only
• B. A barrier that forms between a lead-bearing substance and the environment using a liquid coating or an adhesive bonded covering
• C. A device used to measure lead
• D. A routine cleaning method

Answer: (B)

Encapsulation is a barrier method that seals lead-containing materials from the environment by applying a liquid coating that dries into a film or by using an adhesive-bonded covering. This description captures the essential idea: a coating or bonded layer creates a continuous seal over the lead-bearing surface, reducing dust and exposure. The other options don’t fit because they describe different concepts: a barrier made only of solid material doesn’t emphasize the liquid coating or bonded covering that forms the encapsulating film; a device used to measure lead is unrelated to encapsulation; and a routine cleaning method is about removing lead dust, not sealing it with a coating.
