  • “Lost time injury” is the number of injuries in a year which result in minimum lost time of one working day.
  • “A lost day” occurs when, in the opinion of a physician, an employee cannot work. "Lost days" are counted as calendar days where counting begins on the first day following the injury and ends on the day when the person returns to full duty, receives a permanent job transfer or leaves employment.
  • Lost time injury rate represents the number of injuries per 100 employees per year. It is calculated as the total lost time injuries multiplied by 200,000 and then divided by total hours worked. The factor 200,000 is the annual hours worked by 100 employees, based on 40 hours per week for 50 weeks a year.
