Lost work INDEX

Figure 1. The predicted consequences of one week of detraining and the time of retraining required to recover the full Increase In cytochrome c content (an index of mitochondrial content) In the working muscle. Note that In one week of Inactivity (approx. 1 half-life), nearly 50% of the training effect is lost. Similarly, each week of retraining recovers approx. 50% of the way toward the full training effect. Since the process exhibits first-order kinetics. It takes longer to recover fully.

In contrast to the present treatment there are two types of earlier theories of refraction of light. Yvon32 has developed a statistical-mechanical theory of the refractive index. This theory is set up in such a way that an explicit expression is obtained for the index of refraction. It does not, however, contain an analysis of the optical phenomena (such as the extinction of the incident field) which are involved. These last aspects are considered very carefully in the other, electrodynamic, type of theory, which Hoek,8 following work done by a number of authors, has presented with great rigor. The disadvantage of this second method is that macroscopic quantities are not obtained by statistical-mechanical methods, but by averaging the microscopic quantities oVer physically infinitesimal volume elements. The result is that almost all the effect of density fluctuations is lost. Both of the theories mentioned assume furthermore thp molecular polarizability to be a constant independent of intermolecular distances. 

It is also possible to determine the severity of company injuries. Two methods are typically used. In the first, the total number of days lost due to injuries is compiled from the OSHA 300 daily log and divided by the total number of injuries recorded on the OSHA 300 daily log. This gives an average number of days lost per injury. In the second, the total number of days lost is multiphed by 200,000 and then divided by the number of hours worked by the company employees. This gives a severity index per 100 person hours of work. These measures can also be compa to an industry average. 

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. 

Another performance indicator used by the Department of Energy is the DOE Cost Index. The cost index applies a weighting factor to the frequency of injury and illness cases. The more severe the outcome of the case, the greater the weighting factor. The coefficients are weighting factors, which take into account factors such as dollar costs analyses and cost-benefit analyses. The index is approximately equal to cents lost per hour worked. The DOE Cost Index is computed as follows (Training Resources and Data Exchange [TRADE] 1995, 1-60-61) ... 

This index value indicates that for every hour worked, the organization lost 3.33 due to occupational injuries, deaths, and lost workdays. This index value can be compared to other organizations, and from year to year. With some idea as to what an acceptable index value is, it can be used to benchmark safety performance. 

DOE Cost Index applies a weighting factor to the frequency of injury and illness cases. As a result, the index is approximately equal to cents lost per hour worked. 

The index is approximately equal to the cents lost per hour worked. 

International Labour Office for many years. This was accomplished in Ontario by using the injury index (see Fig. 4). This index can be made available for all construction firms in Ontario from the official Workmen s Compensation Board of Ontario figures, eight to twenty months late. The Association, working with construction companies who volunteer their manhour and lost time injury records, provides the index on a monthly basis (past 12 month record) within six weeks of the month in question. This work for over 1000 participating units is provided by computer. The index reflects the relationship of the company s injury record with that of other companies doing similar work. There are 12 categories or rates.
