A. Scenario.

  (1) A safety and health consultant visited a machine shop, NAICS 33271 and SICS 3599, and recorded the following OSHA 300 Log information:

  (2) This data is used throughout the examples that follow.

B. Calculations.

  (1) Annual Rate Formula Calculations (Year 2005).

    (a) DART.

      (i) DART = [[(COLUMN H) 2005 + (COLUMN I) 2005]  X [200,000 HOURS]] / [HOURS WORKED2005]

      (ii) DART = [[(0) +(1)] X [200,000 HOURS]] / [10,000 HOURS]

      (iii) DART = [[(1)] X [200,000 HOURS]] / [10,000 HOURS]

      (iv) DART = 20.00 = 20.0

    (b) TRC.

      (i) TRC = [[(COLUMN H) 2005 + (COLUMN I) 2005 + (COLUMN J) 2005] X [200,000 HOURS]] / [HOURS WORKED2005]

      (ii) TRC = [[(0) +(1) + (0)] X [200,000 HOURS]] / [10,000 HOURS]

      (iii) TRC = [[(1)] X [200,000 HOURS]] / [10,000 HOURS]

      (iv) TRC = 20.00 = 20.0

    (c) Conclusion. The employer's 2005 DART and TRC Rates of 20.0 are above the 2004 BLS DART and TRC data shown as follows:.

  (2) Three-Year Rate Formula Calculations (Years 2005, 2004, and 2003).

    (a) DART.

      (i) DART = [[(COLUMNS H + I) 2005 + (COLUMNS H + I) 2004 + (COLUMNS H + I) 2003] X [200,000 HOURS]] / [(HOURS WORKED) 2005 + (HOURS WORKED) 2004 + (HOURS WORKED) 2003]

      (ii) DART = [[(0 + 1) + (0 + 0) + (0 + 0)] X [200,000 HOURS]] / [[(10,000) + (14,000) + (12,000)] HOURS]

      (iii) DART = [[(1)] X [200,000 HOURS]] / [36,000 HOURS]

      (iv) DART = 5.56 = 5.6

    (b) TRC.

      (i) TRC = [[(COLUMNS H + I + J) 2005 + (COLUMNS H + I + J) 2004 + (COLUMNS H + I + J) 2003] X [200,000 HOURS]] / [(HOURS WORKED) 2005 + (HOURS WORKED) 2004 + (HOURS WORKED) 2003]

      (ii) TRC = [[(0 + 1 + 0) + (0 + 0 + 0) + (0 + 0 + 1)]  X [200,000 HOURS]] / [[(10,000) + (14,000) + (12,000)] HOURS]

      (iii) TRC = [[(2)] X [200,000 HOURS]] / [36,000 HOURS]

      (iv) TRC = 11.11 = 11.1

    (c) Conclusion. Using the 3-year calculation, the employer's DART and TRC Rates of 5.6 and 11.1, respectively, are above the most recently available BLS data shown as follows:

  (3) Determining eligibility to use the best 3 out of 4 years rate calculations.

    (a) Calculate hypothetical TRC:

      (i) TRC Hypothetical = [[(SUM OF (2) FOR COLUMNS H + I + J FOR 2005)] X [200,000 HOURS]] / [HOURS WORKED2005]

      (ii) TRC Hypothetical = [[(2)] X [200,000 HOURS]] / [10,000 HOURS]

      (iii) TRC Hypothetical = 40.00 = 40.0

    (b) Employer's hypothetical TRC Rate of 40.0 is equal to or higher than the BLS industry average for at least 1 of the past 3 years published; therefore, the employer would be eligible for the best 3 out of 4 years rate calculations.

  (4) Best 3 Out of 4 Years Rate Calculations (Years 2005, 2004, and 2002).

    (a) DART.

      (i) DART = [[(COLUMNS H + I) 2005 + (COLUMNS H + I) 2004 + (COLUMNS H + I) 2002] X [200,000 HOURS]] / [(HOURS WORKED) 2005 + (HOURS WORKED) 2004 + (HOURS WORKED) 2002]

      (ii) DART = [[(0 + 1) + (0 + 0) + (0 + 0)] X [200,000 HOURS]] / [[(10,000) + (14,000) + (16,000)] HOURS]

      (iii) DART = [[(1)] X [200,000 HOURS]] / [40,000 HOURS]

      (iv) DART = 5.00 = 5.0

    (b) TRC.

      (i) TRC = [[(COLUMNS H + I + J) 2005 + (COLUMNS H + I + J) 2004 + (COLUMNS H + I + J) 2002] X [200,000 HOURS]] / [(HOURS WORKED) 2005 + (HOURS WORKED) 2004 + (HOURS WORKED) 2002]

      (ii) TRC = [[(0 + 1 + 0) + (0 + 0 + 0) + (0 + 0 + 0)] X  [200,000 HOURS]] / [[(10,000) + (14,000) + (16,000)] HOURS]

      (iii) TRC = [[(1)] X [200,000 HOURS]] / [40,000 HOURS]

      (iv) TRC = 5.00 = 5.0

    (c) Conclusion. The employer's DART Rate of 5.0 is above the 2004 BLS DART Rate of 2.9. The employer's TRC Rate of 5.0 is below the 2004 BLS TRC Rate of 6.9. Because at least one of the employer's injury and illness rates is above the BLS data, this combination of years would not make the employer eligible for SHARP, as shown as follows:

  (5) Best 3 out of 4 years Rate Calculations (Years 2005, 2003, and 2002).

    (a) DART.

      (i) DART = [[(COLUMNS H + I) 2005 + (COLUMNS H + I) 2003 + (COLUMNS H + I) 2002] X [200,000 HOURS]] / [(HOURS WORKED) 2005 + (HOURS WORKED) 2003 + (HOURS WORKED) 2002]

      (ii) DART = [[(0 + 1) + (0 + 0) + (0 + 0)] X [200,000 HOURS]] / [[(10,000) + (12,000) + (16,000)] HOURS]

      (iii) DART = [[(1)] X [200,000 HOURS]] / [38,000 HOURS]

      (iv) DART = 5.26 = 5.3

    (b) TRC.

      (i) TRC = [[(COLUMNS H + I + J) 2005 + (COLUMNS H + I + J) 2003 + (COLUMNS H + I + J) 2002] X [200,000 HOURS]] / [(HOURS WORKED) 2005 + (HOURS WORKED) 2003 + (HOURS WORKED) 2002]

      (ii) TRC = [[(0 + 1 + 0) + (0 + 0 + 1) + (0 + 0 + 0)]  X [200,000 HOURS]] / [[(10,000) + (12,000) + (16,000)] HOURS]

      (iii) TRC = [[(2)] X [200,000 HOURS]] / [38,000 HOURS]

      (iv) TRC = 10.53 = 10.5

    (c) Conclusion. The employer's DART and TRC Rates of 5.3 and 10.5, respectively, are both above the most recently available BLS data. Therefore, this combination of years would not make the employer eligible for SHARP, as shown as follows:

  (6) Best 3 out of 4 Years Rate Calculations (Years 2004, 2003, and 2002).

    (a) DART.

      (i) DART = [[(COLUMNS H + I) 2004 + (COLUMNS H + I) 2003 + (COLUMNS H + I) 2002] X [200,000 HOURS]] / [(HOURS WORKED) 2004 + (HOURS WORKED) 2003 + (HOURS WORKED) 2002]

      (ii) DART = [[(0 + 0) + (0 + 0) + (0 + 0)] X [200,000 HOURS]] / [[(14,000) + (12,000) + (16,000)] HOURS]

      (iii) DART = [[(0)] X [200,000 HOURS]] / [42,000 HOURS]

      (iv) DART = 0.00 = 0.0

    (b) TRC.

      (i) TRC = [[(COLUMNS H + I + J) 2004 + (COLUMNS H + I + J) 2003 + (COLUMNS H + I + J) 2002] X [200,000 HOURS]] / [(HOURS WORKED) 2004 + (HOURS WORKED) 2003 + (HOURS WORKED) 2002]

      (ii) TRC = [[(0 + 0 + 0) + (0 + 0 + 1) + (0 + 0 + 0)]  X [200,000 HOURS]] / [[(14,000) + (12,000) + (16,000)] HOURS]

      (iii) TRC = [[(1)] X [200,000 HOURS]] / [42,000 HOURS]

      (iv) TRC = 4.76 = 4.8

    (c) Conclusion. The employer's DART and TRC Rates are both below the most recently published BLS data. This combination of years would make the employer eligible for SHARP, as follows:

  (7) For purposes of this section, 200,000 Hours = Base for 100 equivalent full-time employees (working 40 hours per week, 50 weeks per year).
