Incidence rates represent the number of injuries and illnesses per 10,000 full-time workers and were calculated as:
(N / EH) X 20,000,000 where,
N
= number of injuries and illnesses,
EH
= total hours worked by all employees during the calendar year,
20,000,000
= base for 10,000 full-time equivalent workers (working 40 hours per week, 50 weeks per year).
2
Median days away from work is the measure used to summarize the varying lengths of absences from work among the cases with days
away from work. Half the cases involved more days and half involved less days than a specified median. Median days away from work
are represented in actual values.
3
Relative standard errors are a measure of the sampling error of an estimate. Sampling errors occur because
observations are made on a sample, not on the entire population. Estimates based on the different possible samples
of the same size and sample design could differ. Relative standard errors less than 0.05 are not shown.
4
Days away from work cases include those which result in days away from work with or without job transfer or restriction.
5
Includes cases where the nature of injury is: sprains, strains, tears; back pain, hurt back; soreness, pain, hurt,
except back; carpal tunnel syndrome; hernia; or musculoskeletal system and connective tissue diseases and
disorders and when the event or exposure leading to the injury or illness is: bodily reaction/bending, climbing,
crawling, reaching, twisting; overexertion; or repetition. Cases of Raynaud's phenomenon, tarsal tunnel
syndrome, and herniated spinal discs are not included. Although these cases may be considered MSD's, the survey
classifies these cases in categories that also include non-MSD cases.
NOTE: Dashes indicate data that do not meet publication guidelines or data for incidence rates less than .05 per 10,000
full-time workers. The scientifically selected probability sample used was one of many possible samples, each of which
could have produced different estimates. A measure of sampling variability for each estimate is available upon request.
