The results of the CSB incident data analysis are acknowledged as representing only a sampling of recent reactive incident data. This limitation precludes CSB from drawing statistical conclusions on incidence rates or inferring trends in the number or severity of incidents. However, despite these limitations, the data can be used to illustrate the profile and causes of reactive incidents. 

Trend analysis can be confused or invalidated by a sample that is too small. If the charting or analysis is limited only to major incidents, there will often be too few within a period to arrive at meaningful conclusions. For example, a facility with one thousand employees may experience only one or two serious incidents per year, and several years worth of data would be needed to make any meaningful statistical analysis. Minor incidents and near misses can be as useful in trend analysis and preventive prediction as major incidents. All process incidents should be reported, classified, and investigated as appropriate. The severity of an incident is frequently more a function of chance than actual fundamental system differences among accidents and near misses.

The information gathered on transportation incidents has long-term value in addition to the immediate lessons learned. For example, this information may be useful for monitoring performance over time. It can be used to build up a database on transportation incidents. Finally, and most importantly, such information can provide statistical data for transportation risk assessments and improvement efforts. Trend analysis of causes of transportation incidents is vital to a management system that addresses major problems and sets priorities for risk reduction. This element should be part of each supply chain partner s transportation risk management. These risk reduction strategies are discussed in detail in Chapter 7.

The main uses of accident and incident data such as the techniques for learning from the analysis of aggregated accident and incident data, using trend analysis, comparisons of accident and incident data, and epidemiological analyses. 

The most straightforward method of trend analysis is to plot the numbers of accidents or incidents against a suitable measure of time. However, it is also possible to plot on a graph not just the numbers of accidents and incidents but also some measure of severity. T5rpical examples of this sort of measure include days lost through sickness, litres of lost fuel, cost of damage repair, etc. Typical time measures include monthly, quarterly and annually. Figures 2.5.3 to 2.5.6 show examples of these sorts of plots.

As mentioned earlier, determining an accident trend analysis should be relatively easy. In principle, at least, it is easy, or it should be however, a variety of obstacles will probably be encountered when trying to determine the current status of safety culture. In the initial chapters, we discussed how an OSHA log can be a guide to potential problem areas. OSHA logs, accident reports, incident investigations, accident review boards, medical records, worker interviews, OSHA citations, and other information can provide a lot of information about safety culture development.

Category C (possible human carcinogen) was evidenced by a dose-related increase in the incidence of leiomyosarcomas in the urinary bladder, a significant dose-related trend for combined hepatocellular adenomas and carcinomas in males, and a significantly higher incidence of combined lung adenomas and carcinomas in females. For the purpose of risk characterization, the RfD approach should be used for quantification of human cancer risk. The chronic exposure analysis revealed <100% RfD, and it is assumed that the chronic dietary endpoint is protective for cancer dietary exposure [64]. 

In 1985, the United States Federal Register recommended that the analysis of tumor incidence data be carried out with a Cochran-Armitage (Armitage, 1955 Cochran, 1954) trend test. The test statistic of the Cochran-Armitage test is defined as this term ...
