Accident potential

Accepts information concerning facility accident potential or history Events that could result in damage anticipated damage and consequences and historical accident records. 

To be effective, the creation of a task or modification of a task through the introduction of new processes or equipment should automatically require you to develop a new or revised JHA. Jobs with many steps are usually good candidates. As stated before, you should assign each job selected a priority based on the accident potential and the severity of associated potential injuries. 

After the What-lf questions for a process step have been developed, the previously obtained Checklist is applied. Tlie team selects each Checklist item for accident potential and adds them to the What-lf list for evaluation. The checklist is reviewed for each area or step in the process. 

The following is a list by major heading of processes in the Chemical Industry. While accidents can occur in any activity, the scope of the chemical process industry is so wide that processes are selected for description based on judged hazard. These are identified by the number of the section in which they are described. Process not identified by a three digit number are excluded on the basis of low perceived accident potential. 

Hazards inherent in tlic job itself contribute to the overall accident potential of... 

Is there a routine mechanism such as Joh Safety Analysis (JSA) in which tasks such as this are systematically reviewed for potential hazards JSA is a procedure that systematically identifies (1) job steps, (2) specific hazards associated with each job step, and (3) safe job procedures associated with each step to minimize accident potential. 

To start, one must decide whether the substance itself is benign or whether it poses a hazard in the form of toxicity, accident potential, ecosystem destruction, or other form. Hazard can be evaluated in terms for which there is extensive data on properties ranging from dose response to flammability to ozone-depleting potential. In the absence of empirical data, there is a wide range of structure-activity relationship models which can give reasonable approximations for the properties in question.

However, the operations of loading, unloading, storing and sampling have more accident potential than the movement of cargo in closed tanks once they are loaded. 

High crown secondary roads and narrow bridges are only a couple of more accident potentials faced by the drivers. Speed limits are not always observed, and trucks overtaking a passenger car create additional hazards, especially in inclement weather. 

Minimizing waste of a solvent in a given process may inadvertently increase the accident potential. Even though such an action may be beneficial from the perspective of pollution and release to the environment, it may also heighten the potential for a chemical accident or a fire, for example due to product dryness. A process must balance pollution prevention against accident prevention. 

Tlie design, use, and production of chemicals that are less toxic than their current alternatives and inherently safer with regard to accident potential. 

PROCESS DESCRIPTION. A separate element of the PSM Rule (paragraph [d] Process Safety Information) requires documentation of process details. These details need not be repeated in the process description. However, this section of the report should provide a brief working description of the process, perhaps with a block diagram. It should also describe the location of the process and the potential for exposure of workers. The discussion should consider workers working directly on the process and those that are "co-located" but not directly involved in the process. This section should also discuss the relationship between the location or "siting" of the process and the accident potential. 

Because injuries are rare events, they do not always reflect the sum total of daily performance of company employees and managers. Thus, while they are an accurate measure of overall company safety performance, they are an insensitive measure at the individual and departmental levels. Some experts feel that more basic information has to be collected to provide the basis for directing health and safety efforts. One proposed measure is to use first-aid reports from industrial clinics. These provide information on more frequent events than the injuries required to be reported by the OSHAct. It is thought that these occurrences can provide insights into patterns of hazards and/or behaviors that may lead to the more serious injuries and that their greater number provides a larger statistical base for determining accident potential. 

The right-hand column of Table 3.1 provides a new employee risk estimate for each type of new employee (although it makes no allowance for age). The risk estimate uses a simple extreme to low scale, but should serve to illustrate that not all new employees are the same in terms of how their past experience, as defined by their new employee category, will influence their safety risk in a new job. Furthermore, note that no type of new employee is fully protected from safety risks by their past experience (past employment history). It is also important to note that experience is only one factor which influences new employee safety risk. Thus, while a new employee may be classified as a moderate-to-low risk in terms of Table 3.1, there may be other factors associated with their entry into a new job which increase their accident potential. Section 3.7.2 in this chapter discusses the assessment of job applicant experience at the time of recmitment and how this can be used to help ensure new employee safety. 

This method cooperate the rope exchange vehicle can realize the function of sending new rope and drawing old rope automatically. Implements all operations accomplished at wellhead, quick and convenient, the operator and accident potential less than before, achieve high safety and efficiency.

The persons are selected on a stratified random sampling basis, with stratifications designated according to the type of exposure, quantity of exposure, degree of hazard present, and other criteria considered important to the representativeness of the sample. The objective is to discover causal factors that are critical, that is, that have contributed to an accident or potential accident situation. The unsafe acts and unsafe conditions identified by this method then serve as the basis for the identification of accident potential problem areas and the ultimate development of countermeasures designed to control accidents at the no-loss stage [p. 304],... 

Another is sue is the focus on inj urie s vs. maj or accident potential - a too strict focus on injuries could reduce exploration of major accident potential.

The overall objective for this paper in relation to the RIO project is to explore the effects on the major accident potential related to new conditions for situational awareness. The more specific scope is to explore whether the findings from a study o f a speci fic asset and its lO practice and organization (Skarholt Ntesje, 2008) actually validate a more general analysis of the implications of lO in terms of potential for major accidents (Grotan et al., 2008). 

In chapter 6, an a posteriori estimate of the accident potential is outlined by using the case desrciption to challenge the a priori estimates, one by one. 

Here, we evaluate whether and how the case description above affect the a priori estimates of Grotan et al. (2008) concerning positive/negative effects from 10 on the accident potential. A central premise for this estimate at an overall level, is the distinction between work process (what to do) and work form (how to do it - together). 

By implication, the evaluation constitutes an a posteriori estimate of the accident potential. However, due to the narrower scope of the evaluation case, results should not be considered as more true in any...
