Night-shift safety-critical worker with new epilepsy diagnosis
A 34-year-old process operator at a chemical plant works a rotating 12-hour shift pattern including nights. He is responsible for monitoring alarms and manually overriding a safety interlock during batch transfers. He has had two witnessed generalised seizures in the last four months, both while sleep-deprived after night shifts. His neurologist has started him on lamotrigine, titrating upward, and says seizure control is 'likely but not yet established'. He wants to keep working and says he cannot afford to lose his job. The plant has no other vacancies at his grade and the employer asks you to declare him fit so he can return next week.
1. How do you assess his fitness for this specific role, and what do you tell the employer?
Read the worked answer
Fitness must be judged against the demands of the actual job, not a generic label.
- Key hazards: he holds a safety-critical role (alarm monitoring, overriding an interlock), works nights, and his seizures have been triggered by sleep deprivation. A seizure during a batch transfer could cause a process safety event as well as personal injury.
- Current status: seizure control is not yet established and he is mid-titration, so the risk is not stable and cannot be reliably predicted.
- Conclusion: he is not currently fit for unrestricted safety-critical shift work, particularly nights. This is a temporary judgement based on current control, not a permanent bar.
- What I tell the employer: the specific restrictions and their rationale (without disclosing unnecessary clinical detail), a review date, and the need to consider reasonable adjustments. I would not simply sign him fit because of financial pressure; that pressure is a reason to look harder for adjustments, not to lower the safety bar.
- Review: re-assess once he is established on treatment and seizure-free for a defined period agreed with the neurologist, and reassess the night-work component specifically.
2. What adjustments would you explore, and how do you handle the conflict between his wish to keep his job and the safety risk?
Read the worked answer
Adjustments should target the modifiable risk factors.
- Shift pattern: remove or reduce night work and rotating shifts, since sleep deprivation is his identified trigger. A fixed day pattern, if one exists at his grade, would substantially reduce risk.
- Task modification: temporarily move him away from safety-critical interlock overrides and alarm monitoring to supervised or non-safety-critical duties while control is established.
- Buddy/supervision: pair him with a colleague during higher-risk tasks as an interim measure.
- Environmental/first-aid: ensure colleagues know what to do if he has a seizure, and review lone-working arrangements.
- Communication and consent: discuss options with him, explain the reasoning, and involve him in decisions. Explain that the aim is to keep him in work safely, and that restrictions are time-limited and reviewable.
- If no adjustment is possible: be honest that the role as configured is not currently suitable, and discuss redeployment, temporary alternative duties, or referral for specialist occupational advice. Document the reasoning. Signing him fit to satisfy the employer or his financial worry would be the wrong call.
