Selecting the Job to be Analyzed

The first component requires that a job be selected for analysis. Each supervisor in each department will require a complete listing of jobs. It is important to prepare a listing of position titles, hazardous jobs, jobs that have resulted in close calls, jobs that are nonroutine and jobs that have resulted in disabling or severe injuries. A typical warehouse may compile of list of between 75 and 150 jobs. 

In selecting the job to be analyzed, consideration must be given to the following. 

All jobs that have a history of producing many injuries are excellent choices for a JHA. It is a safe assumption that a job that has produced a large share of injuries in the past will continue to produce injuries unless changes are made to the job. The greater the number of injuries associated with a job, the greater the need to be a part of JHA. 

Jobs that have produced disabling injuries are also excellent candidates for JHA. Obviously, these jobs should take priority over those that have produced less serious or first aid injuries. Disabling injuries are very costly as well as devastating to the injured worker and his/her family. 

Some jobs have a history of producing few injuries but have the potential of being severe when they do occur. The injury could be crippling or fatal. These jobs cannot be excluded from JHA because they seldom produce injury.

A JSA can be performed using three basic steps, but a careful selection of the job to be analyzed is an important preliminary step. 

To use the JSA/JHA program effectively, a method must be established to select and prioritize the jobs to be analyzed. The jobs mnst be ranked in the order of greatest accident potential. Jobs with the highest risks shonld be analyzed first. Workers and supervisors may or may not be involved with the ranking process, but if asked to rank or prioritize jobs to be analyzed, the following criteria shonld be used ... 

The first step of a JHA is to select a job to be analyzed. The sequence in which jobs are analyzed should be established when starting a JHA program. Potential jobs for analysis should have sequential steps and a work goal when these steps are performed. 

Implementing a safety performance system starts with defining the job-performance objectives for the position to be analyzed. This will require a thorough and accurate analysis of the job. The most common task analysis method for analyzing jobs requires a decomposition of job tasks into simpler subtasks, component tasks, or steps (Kaufman, Thiagarajan, and Sivasailam 1997, 189). The safety field is familiar with this process, as it is a common approach to conducting safety-related analyses such as job safety analyses or procedure analyses. Selection of the job tasks to analyze... 

In selecting jobs to be analyzed and establishing the order of analysis, top supervision is guided by the following factors ... 

Selecting jobs to be analyzed is done on a priority basis. Select jobs based on the following guidelines. 

For almost all particle size analyses only a small fraction of the material to be investigated is used. From the total amount, which may be as large as several hundred cubic meters or tons, a representative sample is taken, which must be split, i.e. reduced in volume, until an amount is obtained which, in its entirety, is suitable for use in the analyzer selected for the job. Depending on the method for analysis this amount may weigh only a few milligrams. The surface or particle size distribution is determined on this sample and it is assumed that the characteristics of the total amount of material exactly correspond with these results. 

The above guidelines are prepared in a priority listing. It makes sense to select a high-risk job for evaluation rather than one that has a history of producing few injuries. A supervisor should consider, What s the worst thing that can occur in my department what operation could produce the most serious injury The selection of these high-risk jobs is the correct place to start. Eventually, all of the jobs in the warehouse will be analyzed and those of lowpriority/low risk will be completed. 

Measurement uncertainty is a critical parameter for nearly every kind of analytical system. Parameters in the second column of table 8.3 are not unimportant and must be established, but they are not likely to become limiting factors in the development of the method. In table 8.3, where selectivity is in parentheses, this is not to say that the method should not be demonstrably capable of analyzing the target analyte, but that it should be clear very quickly whether or not the method is doing its job. 

A designated person should be selected to coordinate the overall JHA process and act as the clearinghouse for documents used in analyzing jobs. The person selected should have a combination of the following traits ...
