DART incident rate

Number of injuries in column H + Number of entries in column I) Number of hours worked by all employeesx 200,000 hours = DART incidence rate... 

OSHA and BLS also compute the incident rate for cases classified as death, cases resulting in days away from work and cases involving restricted job duties or a job transfer. This is the DART incident rate. The acronym derives from letters from the three categories. 

A severity measure helps illustrate the impact of severe cases. The OSHA DART incident rate is one form of a severity measure. 

Combined operations recordable and lost workday/DART case incident rates... 

Indemnity Case Rate, which is a negative metric providing the rate of all workers compensation cases that involve lost time payments per 100 full time employees per year. It may be indicative of the company s basic prevention and reduction efforts in minimizing more serious lost time case incidence and severity. It relates closely to OSHA s DART or rate of injuries and illnesses resulting in days away from work, restricted work activity, and/or job transfer. According to Italian National Standards UNI 7249 (UNI 2007) further index rates are introduced, like incidence index of occurred accidents, defined as rate of occurred accidents per 1.000 workers, frequency index (rate of occurred accidents per 1.000.000 hours worked), severity index of accidents, which represents 1000 times total number of lost days per hours worked. 

You can compute the incidence rate for recordable cases involving days away from work, days of restricted work activity or job transfer (DART) using the following formula ... 

An acronym for Days Away, Restricted work activity, and/or job Transfer (DART) Case Incidence Rate and is defined by the Occupational Safety and Health Administration (OSHA) as the rate of recordable 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. Restricted cases are defined as any occupational injury or illness that results in the limitation of employees ability to do their job (i.e., no lifting, climbing, etc.) or being transferred to another job (restricted days). The annual DART rate is calculated according to the following formula ... 

To qualify for the Star designation, an entity must show that its 3-year illness and injury Total Case Incidence Rate (TCIR) and its 3-year Days Away from Work, Restricted Work Activity, and Job Transfer Rate (DART) fall below the entity s industry average. That suggests exclusivity and deserved recognition for those companies which have superior safety and health management systems and stellar performance. 

Site management must maintain copies of the TCIR (total case incident rate) and DART (three year day away, restricted, and/or transfer case incident) rate data for all applicable contractors based on hours worked at the site.. .. 

Combined Operations Recordabie and Lost Workday/DART Case incident Rates... 

Once you know your establishment s NAICS code, go to httpy/www.bls.gov/iLfioshsmn.htm. Find the Summary Table called Table 1 - Incidence rates - detailed industry level. Scroll through the BLS table and find the corresponding NAICS code in the left-hand colmnn. (NAICS data are presented in numeric order in the BLS Table). To compare your injury and dlness rates, use the number listed in the Total recordable cases column for your NAICS as the industry average incidence rate. Use the number listed in the total from the Cases with days away from work, job transfer, or restriction column as the industry average DART rate. Note At press time, the most current data available were for calendar year 2011 injuries and illnesses 2012 should be available soon. 

The same formula can be used to compute the incidence rate for the most serious injury and illness cases, defined here as cases that result in workers taking time off from their jobs or being transferred to another job or doing lighter (restricted) duties. ABC Company had 7 such cases. The DART rate for these 7 cases is computed as (7 X 200,000) / 400,000 = 3.5... 

In situation one, the organization to which the safety professional gives counsel has OSHA incident and lost-workday case rates (DART rates) three times that of its industry averages. Much needs to be done to bring operational risks down to acceptable levels. Leading indicators selected would be for the basics of an operational risk management system and a measurement system could be established with suitable and attainable goals. 

To calculate the severity rate (SR), use the same formula that you use to calcrdate the DART rate except that the total number of days away from work, days of restriction, and days of transfer are substituted into the nrunerator in place of the total nrunber of incidents.
