Correct answer: E — No, health surveillance should continue for as long as exposure continues, as sensitisation can develop at any point during ongoing exposure

Isocyanate sensitisation can develop at any point during exposure, even after many years. HSE guidance is clear that surveillance must continue for the duration of exposure. Absence of symptoms to date does not predict future risk.
