	Reducing Incidents during Daylight Saving Time - National Security Technologies, LLC (NSTec) 
Statement of Lessons Learned 
National Security Technologies, LLC (NSTec) used predictive analytics to quantify and evaluate 12 years of historical incident data specific to the week following Daylight Saving Time (DST) to predict the likelihood of incidents. The use of predictive analytics and development of target responses was found to be very successful in reducing incidents.

The root cause of injuries during the week after DST was found to be due to sleep deprivation.  This, combined with other causal factors, resulted in a prediction of 3.29 (rounded to 3) injuries for the week following DST 2016. 
Discussion of Activities 
To prevent injuries during the week following DST 2016, NSTech wrote specific informational articles targeting the root cause and casual factors for publication in the March Safety Topic newsletter followed by  specific call to action email notifications and an InSite Quick Poll to all employees.  Additional emails were targeted to employees at four NSTec locations.

Research of individual�s attention span, cognitive retention, and behavioral �nudges� showed that articles demonstrating long-term safety goals that had demonstrated a connection between the present and long-term goals of an individual resulted in positive results.  The end result of this project was NSTech�s first zero injuries related to job function, task or responsibility week occurred during the week following the start of DST 2016. 
During a normal 4-day workweek (Monday - Thursday) incidents following DST plateaued Tuesday and Wednesday. It was found that the relationship between sleep and increased mid-week injuries was a quantified assumption being the difference in sleep patterns from weekend to workweek and heightened by the effect of DST. 

Evidence of variation between sleep patterns of workweek and weekend is quantified by the reliance of an alarm clock during the normal work week for most individuals. As a result, sleep opportunity is reduced on work days.  Complacency is also a behavioral issue that can be triggered as the mind seeks to streamline current tasks and by physical conditions such as fatigue. Both repetition and fatigue-induced complacency can increase the opportunity for injuries. 
Recommended Actions 
As a result, ZERO incidents (a historic first for NSTec) related to job function, task or responsibility occurred during the week following the start of Daylight Saving Time 2016. 
JLab Preventive Measures 
Jefferson Lab is providing this Lesson Learned as a reminder that Daylight Savings Time and the return to Regular Time can lead to disruption in sleep patterns and changes in other activities.
