During investigations evidence on possible fatigue should be sought. ); e) whether sufficient rest is actually obtained on rest days; f) changes in workload on site and environmental conditions during the work. Night workers are particularly at risk of fatigue because their day sleep is often lighter, shorter and more easily disturbed because of daytime noise and a natural reluctance to sleep during daylight.

Changes to working hours need to be risk assessed. This is possibly related to the probability of a high stress interacting with a critical flaw within a certain volume, i.e., when the volume is large there is a higher probability of failure.

Discuss controls with crew/team and with Supervisor. 1 Use Excel Goal seek to change crack size until fracture ratio = 100%. There are many different shift work-schedules and each schedule has different features.
