Correct answer: C — Remove from isocyanate exposure and arrange urgent specialist respiratory assessment

Isocyanates are potent respiratory sensitisers and can cause occupational asthma, sometimes with immediate allergic features. Continuing exposure while awaiting routine review can worsen long-term prognosis. Immediate exposure control, review of RPE and referral for occupational respiratory assessment are appropriate.
