Fatiguefit Census
Find out how your organization manages fatigue today, and how fatigued your safety-sensitive people actually are, before you buy anything else.
Risk & Safety · Fatiguefit and Sleepfit
Fatigue is a hazard. After an incident, you’ll be asked how you controlled it.
US law expects employers to keep the workplace free of recognized hazards, and fatigue can be one of them. 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 defense.
A compliant schedule can still put a fatigued crew to work: what predicts impairment is the sleep people actually got, not the hours on the roster.
Hours-of-service rules set limits in rail, aviation and trucking, and since 2022 the Federal Railroad Administration has required railroads covered by its safety program rules to include a fatigue risk management program. Beyond those rules, the OSH Act’s General Duty Clause requires employers to protect workers from recognized hazards, and fatigue can be one.
After a serious incident, investigators and plaintiffs ask the same question: what did you know about fatigue, and what did you do about it? In 2014 a federal accident investigation recorded the absence of sleep-disorder screening as a contributing cause of a fatal train crash.
Nothing we provide discharges that obligation. What each product does is produce evidence that an element of your fatigue risk management program was carried out, to a standard you can show.
Where we sit
Controls at the levels you can evidence.
- 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 controlledHours-of-service rules and roster design, supported by bio-mathematical modeling of work patterns.
Where we sitNot coveredWe do not operate at this level. Nothing we provide reduces your hours-of-service obligation or substitutes for roster design.
- 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 controlledMeasuring the sleep actually obtained across a workforce, and acting on what it shows.
- Level 3
Behavioral symptoms at work
Fatigue is present in the shift and is showing in behavior, whether or not the person has recognized it.
How it is controlledStructured assessment at role and task level: sleepiness scales, symptom checklists and trained observation.
- 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 controlledFatigue-proofing: task design, cross-checking, error-tolerant procedures and timing critical work away from the circadian low.
Where we sitNot coveredWe do not operate at this level. It is engineered into your safety management system, and awareness training is not a substitute for it.
- Level 5
Fatigue-related incidents
It has already happened. The value now is in what the organization learns from it.
How it is controlledStructured investigation of whether fatigue contributed and through which pathway, feeding back into the levels above.

The products
Fatiguefit and Sleepfit
Sleepfit
Measurement of the sleep your workforce is actually getting, with validated screening that surfaces risk that never presents to a health service.
Fatiguefit4Duty
Structured assessment at the point of duty, combining the sleep a person actually got in the last 24 and 48 hours with how alert they feel now.
Awareness eLearning
Fatigue training for employees and managers: what makes the controls at Levels 2 and 3 usable by the people running them.
Was It Fatigue?
Structured post-incident analysis of whether fatigue contributed to an event, and through which pathway.
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.
