4.8.2.1 Normal Operations
The hours of service limits for normal operations for 10-hour shifts are as follows:

• Dunng outages, individuals tend to work fixed shifts. 36 hours between work sets provides for 2 consecutive sleep opportunities, thereby allowing workers to remain on their established circadian cycle, rather than encouraging night shift workers to revert to night sleep on their off days, which likely would occur with longer time between work sets.
