A Fatigue Checkcard for Mishap Investigations

Abstract

Investigators of workplace and transportation accidents and incidents seldom have the instruments or expertise required to determine whether or not human fatigue might have contributed to the mishap. The Fatigue Checkcard and its associated protocol were designed as a screening tool to fill this need. Briefly, using the Checkcard, the investigator may generate a score based upon seven simple observations: length of prior wakefulness, amount of prior sleep for the preceding 72 hours, time of mishap, number of night shifts in preceding 30 days, time zone change and days in zone, types of human errors associated with mishap, and estimated physical exertion across the work period of interest. If the score is above a criterion level shown on the card, then the investigator should contact a fatigue expert for additional help with the investigation.
