Job analysis

Careful observations of the course of iodo-de-diazoniation demonstrate that the detailed pathway of such reactions is still relatively complex. For instance, after adding a solution of KI to a solution of an arenediazonium salt, normally molecular iodine appears to be formed first, followed by a precipitate and evolution of N2. Carey and Millar (1960) isolated the salt ArNJIj- on adding iodide to the diazo-nium salt. Ion pairs (ArNjHlg-), suggested as primary products by Meyer et al. (1979), were identified for diazonium halides (Cl- and Br-) by Israel et al. (1983) as 1 1 complexes on the basis of JOB analyses of visible spectra (Benesi-Hildebrand method). Iodides were, however, not included in that investigation.

Screening criteria are developed from job analyses. Job analyses are systematic reviews of the requirements of a job (Donnelly, Gibson, and Ivancevich, 1995). Job analyses attempt to identify some of the following aspects of a job ... 

Determine the main factors that may be causing lower than expected levels of the quality characteristic. Main factors can be identified through data analysis (i.e., highest frequencies), job analyses, etc. 

Obviously, this approach requires rehance on personal-breathing-zone sampling or detailed job analyses for all classifications studied, and a comprehensive program of sampling sufficient to estabtish average airborne concentrations at aU work sites. 

Useful tools for this purpose include job analyses and descriptions, task analyses and procedures, work practices, performance observations, tests, and surveys.

Planning is defined as the process of analysing each job so as to determine the nature of the job and the results desired specify the logical sequence of the job and apply humanpower and estimates for each sequential step Hst predeterminable material, tools, and special equipment and estimate the total cost to meet the required results. 

Other information may also benefit the PHA. Standard operating procedures for processing equipment, safe work practices, maintenance or job safety analyses, emergency response plans could be appropriate review items for some PHAs depending upon the toll. 

Maintenance and production records, along with the used lean and rich glycol analyses, can be very helpful to the troubleshooter. A history of filter element, carbon, tower packing, and firetube changeouts can sometimes be very revealing. The frequency of pump repairs and chemical cleaning jobs is also beneficial. With this type of knowledge, the troubleshooter can quickly eliminate and prevent costly problems. 

Identify jobs and tasks that require hazard analyses. 

Integrate hazard analyses to identify worker hazards and to provide a basis for speeifieation of job and task hazard eontrols. (The upeoming seetion eovering hazard eharaeterization and exposure assessment will provide some suggestions on effeetive ways of eondueting hazard analyses using the HAZWOPER job, task, and hazard analysis approaeh [1].)... 

To determine which jobs you should analyze first, review your injury and illness reports such as the OSHA 200 log, your medical case histories, your first-aid cases, and workers compensation claims. First, you should conduct a JHA for jobs with the highest rates of disabling injuries and illnesses. Do not forget jobs in which you have had close calls or near hits. You should give these incidents a high priority. Analyses of new jobs and jobs in which changes have been made in processes and procedures should be the next priority. 

Not all required tasks and hazards can be predicted during the development of a HASP. The plan describes the ongoing hazard analysis and work control process, defines the means of identifying job- or task-based requirements and controls, and discusses ways to inform workers about requirements derived from ongoing job or task hazard analyses. 

Work planning and control processes include the use of job hazard analyses (JHAs), job safety analyses (JSAs), task analyses, safe work plans, safe work permits, or procedures. 

Prior to beginning any training activity, exact training needs should be identified. Training needs may vary based on hazards, potential exposures, work requirements, roles and responsibilities, job descriptions, and compliance requirements. Job hazard analyses and employee surveys... 

The contractor s SSAHP for Site C contained task- and operation-specific hazard analyses and safety and health procedures that covered general operations, but they were not specific enough for prescribing control methods and PPE for each job task. The plan identified some safety hazards for each operation but did not describe SOPs for protecting employees from these hazards. The SSAHP did, however, contain personnel and equipment decontamination procedures used at the site. 

The contractors SSAHPs at Sites B, F, and K had general confined space provisions but lacked site-specific confined space procedures. For example, SSAHPs for the Site K contractor and subcontractor had written confined space entry programs, but the programs did not establish site-specific rescue procedures or identify the confined space hazards present on the site. The job hazard analyses for both programs failed to address site maintenance tasks that could involve confined space entry and hot work hazards. The programs also failed to identify the specific person or position responsible for supervising confined space entry procedures and the location of permit-required confined spaces on site. Interviews with both contractors indicated confusion about rescue procedures. 

The SSAHP developed by the Site G contractor did not indicate that the contractors routinely conducted job- or task-specific hazard analyses. In addition, the SSAHP did not specify that PPE selection for jobs and tasks must be based on the analysis of the health hazards associated with each job. Eurthermore, the SSAHP contained no procedures for objectively determining the effectiveness of decontamination of personnel or equipment. The decontamination program required incineration of all materials that could not be readily decontaminated such materials were placed in labeled disposal containers. The program, however, did... 

On July 17, 1990, OSHA issued a proposed rule for the management of hazards assoeiated with proeesses using highly hazardous ehemieals. This rule, ealled the Proeess Safety Management Standard, was finalized on February 24, 1992. In an appendix to the proposed rule, OSHA diseussed several methods of proeess hazard analysis. That diseussion may be helpful for those doing job hazard analyses. Refer to Chapter 4 for these methods.

Information on the types of human interactions with hazardous systems that occur would be obtained from sources such as plant operating instructions, job safety analyses and similar sources. These interactions are referred to as critical tasks (CT). 

It is difficult to obtain accurate particle size analyses of primary expls because (1) consideration and acceptance of necessary safety precautions make the usually tedious job of particle size analysis even more tedious, and (2) many primary expls used in production contain particles which are non-spherical in shape and are in the subsieve size range. Dry screening Lead Azide, for instance, is hazardous and must be done remotely. Furthermore, static charges... 

Hence, the choice of method and the validation of the method selected become increasingly more critical for those analyses resulting in actions towards the bottom of the list than for those at the top. You now need to pause to consider what the consequences of poor analytical work could be in your own particular job. Do not forget to include longer-term implications as well as the immediate problems. Poor or wrong data also result in the loss of reputation - customers who never come back. 

To analyse these problems, the impact of fuel-cell technologies on the service sector was analysed in Germany in a project of the BERTA programme financed by the German Federal Ministry of Economics.3 The possible impacts were examined with regard to job profiles, qualifications and the job market, to prepare the branches involved most optimally. 

The main elements of the used input output model ISIS are described in the following. At the core of ISIS is a statistical input output model (IO model) used to examine the structural impacts of the various strategies. Other modules for employment effects, qualification structure and job conditions, regional effects and environmental effects were developed or added to analyse other dimensions of sustainability. The results of the scenario calculations from the IO model, i.e., production changes as a result of the different strategies, serve as inputs for the other modules.
