Which action is an interim control measure?

• A. Permanent sealing of the surface
• B. Dust removal
• C. Remove all paint permanently
• D. Hold a public meeting

Answer: (B)

Interim controls are temporary steps taken to reduce exposure to lead hazards while a permanent solution is planned or implemented. They focus on practical actions that lower lead dust and contamination now rather than performing a full remediation. Dust removal fits best because it immediately reduces the amount of lead dust in the environment, cutting inhalation and ingestion risks right away without committing to a permanent fix. The other options are either long-term/removal strategies (permanent sealing of a surface, removing all paint) or a non-technical activity (holding a public meeting) that doesn’t directly reduce exposure in the environment.
