Risk & Safety · Fatiguefit and Sleepfit

Fatigue is a hazard. After an incident, you’ll be asked how you controlled it.

Ireland’s Safety, Health and Welfare at Work Act 2005 expects you to manage fatigue like any other hazard: identify it, assess the risk, control it so far as is reasonably practicable, and be able to show you did. Fatiguefit and Sleepfit give you the assessment, sleep-disorder screening for safety-critical roles, the point-of-duty control, the training record and the investigation method, each producing evidence you can file.

The liability question

Hours rules are the floor, not the defence.

A compliant roster can still put a fatigued crew to work: what predicts impairment is the sleep people actually got, not the hours on the roster.

In most sectors the duty is risk-based rather than a simple cap on hours: you must be able to show how your rosters, monitoring and training actually manage fatigue, and prove it after the event.

Directors and managers can be prosecuted personally where an offence involves their consent, connivance or neglect, and fines on indictment run to millions of euro.

Nothing we provide discharges that obligation. What each product does is produce evidence that an element of your fatigue risk management programme was carried out, to a standard you can show.

Where we sit

Controls at the levels you can evidence.

  1. Level 1

    Sleep opportunity

    The roster does not allow enough time for adequate sleep. The failure is in the work pattern, before anyone has slept badly.

    How it is controlled

    Hours-of-service rules and roster design, supported by bio-mathematical modelling of work patterns.

    Where we sit

    Not coveredWe do not operate at this level. Nothing we provide reduces your hours-of-service obligation or substitutes for roster design.

  2. Level 2

    Sleep obtained

    The opportunity to sleep existed, but the sleep did not follow: an undiagnosed disorder, psychological distress, life stage, environment or habit.

    How it is controlled

    Measuring the sleep actually obtained across a workforce, and acting on what it shows.

  3. Level 3

    Behavioural symptoms at work

    Fatigue is present in the shift and is showing in behaviour, whether or not the person has recognised it.

    How it is controlled

    Structured assessment at role and task level: sleepiness scales, symptom checklists and trained observation.

  4. Level 4

    Fatigue-related errors

    Fatigue is present and has produced an error. The only question left is whether the system catches it before it reaches the operation.

    How it is controlled

    Fatigue-proofing: task design, cross-checking, error-tolerant procedures and timing critical work away from the circadian low.

    Where we sit

    Not coveredWe do not operate at this level. It is engineered into your safety management system, and awareness training is not a substitute for it.

  5. Level 5

    Fatigue-related incidents

    It has already happened. The value now is in what the organisation learns from it.

    How it is controlled

    Structured investigation of whether fatigue contributed and through which pathway, feeding back into the levels above.

The products

Fatiguefit and Sleepfit

See what sleep and fatigue mean for your workforce.

Tell us your industry and roughly how many people you employ. Your snapshot models how many are likely sleeping poorly and what it costs you. Then choose who you’d cover, and we’ll scope the right next step with you: a Fatiguefit Census where fatigue is a safety risk, or a proposal for a wellbeing program.
