A paint-manufacturing plant uses a solvent with a biological monitoring guidance value. Air monitoring is within the workplace exposure limit, but skin contamination is observed during cleaning and workers report headaches after spills. What is the most appropriate health surveillance?

Correct answer: C — Use biological monitoring to assess total uptake and review controls

Biological monitoring can assess uptake from inhalation, skin absorption and ingestion, complementing air monitoring. Visible skin contamination and symptoms suggest exposure routes may not be adequately captured by air sampling alone. It should be used with consent, explanation and control review. Imaging and pulse oximetry are not appropriate surveillance tools for solvent uptake.
