HSE Fatigue and Risk Index (FRI) Calculator

This tool is no longer available on the HSE website but they say you can "continue to use it provided you have the necessary expertise to use the tool and understand the outputs and limitations"

Here is a link to a copy of the Calculator BUT PLEASE READ AND BE MINDFUL OF THE FOLLOWING EXTRACT FROM NETWORK RAIL'S STANDARD

FRI CALCULATOR

The FRI should not be used on its own to consider a roster or selection of rosters.

The tool does not take into account a number of factors that may impact how

appropriate a particular roster is, and these include:

a) quality and length of sleep between shifts;

b) whether rest breaks are taken as detailed within the tool’s default settings;

c) personal preference (are people morning/evening/night people?);

d) ability to adjust to night working;

e) whether sufficient rest is actually obtained on rest days;

f) changes in workload on site and environmental conditions during the work

activity;

g) domestic and/or personal circumstances or situations;

h) whether individuals are actually turning up well-rested and fit for duty.

These should be considered at a local level when reviewing the roster and

judgement made about the impact they might have. Education on individual

responsibility, health and wellbeing lifestyle choices on managing fatigue outside of

work is advisable.
