Marked improvement in worker safety

Los Alamos shows marked improvement in worker safety from 2017 to 2018 (as measured by days away from work for illness and injury).

Since June 2006, the Lab’s Total Recordable Cases (TRC) and Days Away Restricted Transfer (DART) rates showed a 76 and 89 percent decrease, respectively.

These rates are lower than nationwide and New Mexico averages.

Total Recordable Incident Rate (TRC) is a widely recognized measure of occupational safety and health  in the workplace that is calculated by combining the actual number of work-related injuries/illnesses and total work hours of all employees with a standard employee group (100 employees working 40 hours a week for 50 weeks a year).

Days Away Restricted Transfer Rate (DART) describes the number of recordable injuries and illnesses per 100 full-time employees that resulted in days away from work, restricted work activity and/or job transfer that a company has experienced in any given time frame.
