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:
Year | Number of Employees |
Hours Worked |
Column H |
Column I |
Column J |
2005 | 5 | 10,000 | 0 | 1 | 0 |
2004 | 7 | 14,000 | 0 | 0 | 0 |
2003 | 6 | 12,000 | 0 | 0 | 1 |
2002 | 8 | 16,000 | 0 | 0 | 0 |
(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:.
YEARS | DART | TRC |
2005 Employer's Rates | 20.0 | 20.0 |
2004 BLS Data | 2.9 | 6.9 |
(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:
YEARS | DART | TRC |
2005, 2004, and 2003 Employer's Rates | 5.6 | 11.1 |
2004 BLS Data | 2.9 | 6.9 |
(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
2004 BLS TRC Rate = 6.9
2003 BLS TRC Rate = 7.5
2002 BLS TRC Rate = 7.5
(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:
YEARS | DART | TRC |
2005, 2004, and 2002 Employer's Rates | 5.0 | 5.0 |
2004 BLS Data | 2.9 | 6.9 |
(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:
YEARS | DART | TRC |
2005, 2003, and 2002 Employer's Rates | 5.3 | 10.5 |
2004 BLS Data | 2.9 | 6.9 |
(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:
YEARS | DART | TRC |
2004, 2003, and 2002 Employer's Rates | 0.0 | 4.8 |
2004 BLS Data | 2.9 | 6.9 |
(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).
