5.11.4. Ground Mishaps.
5.11.4.1. On-Duty Ground Metric (Rate). This metric applies to both military and
civilian personnel and is used to identify the number of mishaps, fatalities or injuries
experienced by military and civilian personnel while on-duty per 100,000 personnel per
FY. To calculate daily, monthly or yearly on-duty rates, multiply the total number of
military and civilian mishap, fatalities or injuries by 100,000 personnel divided by the
military and civilian strength. NOTE: When calculating rates for periods of time less
than one year, the reduced exposure time must be accounted for as provided in the
monthly and daily examples below. NOTE: AFSC calculates daily and yearly statistics
based upon AFPC strength numbers.
5.11.4.2. Off-Duty Ground Metric (Rate). This metric applies only to military personnel
and is used to identify the number of mishaps, fatalities or injuries experienced by offduty
military personnel per 100,000 personnel per year. To calculate daily, monthly or
yearly off-duty rates, multiply the total number of military mishap, fatalities or injuries x
100,000 personnel divided by the military strength (see examples in paragraph 5.11.4.1
above except exclude civilian strength). NOTE: When calculating rates for periods of
time less than one year, the reduced exposure time must be accounted for as provided as
in the examples in paragraph 5.11.4.1 above. NOTE: AFSC calculates daily and yearly
statistics based upon AFPC strength numbers.
5.11.4.3. Private Motor Vehicle (PMV) Off-duty Fatality Metric (Rate). This metric
applies only to military personnel and is used to identify the number of off-duty PMV
mishaps, fatalities or injuries experienced by off-duty military personnel per 100,000
personnel (see examples in paragraph 5.11.4.1 above except exclude civilian strength).
NOTE: When calculating rates for periods of time less than one year, the reduced
exposure time must be accounted for as provided as in the examples in paragraph
5.11.4.1 above.
5.11.4.4. Total Case Incident Rate (TCIR). This metric applies only to civilian personnel
and is used to identify the total number of recordable (Class A, B, C, and D) civilian
injuries and illness cases per 100 full-time employees that a site has experienced per year.
Rationale: The 200,000 hours are based on 100 full-time workers working 40 hours per
week, 50 weeks each year (100 x 40 hours per week x 50 weeks). Total man hours
worked equals the personnel strength x 40 hours per week x 50 weeks per year plus
overtime hours worked. NOTE: When calculating rates for periods of time less than one
year, the reduced exposure time must be accounted for as provided in the examples in
paragraph 5.11.4.1 excluding military strength. NOTE: Actual hours to include overtime
should be used for computing civilian hours worked.
5.11.4.5. Days Away, Restricted, and/or Transfer (DART) Case Incidence Rate. This
metric applies only to civilian personnel and is used to identify the total number of
recordable civilian injuries and illness cases per 100 full-time employees resulting in days
away from work, restricted work activity, and/or job transfer that a site has experienced
in a given time frame. Rationale: The 200,000 hours are based on 100 full-time workers
working 40 hours per week, 50 weeks each year (100 x 40 hours per week x 50 weeks).
Total man hours worked equals the personnel strength x 40 hours per week x 50 weeks
per year plus overtime hours worked. NOTE: When calculating rates for periods of time
