For jet fuels, the elimination of free water using filters and coalescers by purging during storage, and the limit of 5 ppm dissolved water are sufficient to avoid incidents potentially attributable to water contamination formation of micro-crystals of ice at low temperature, increased risk of corrosion, growth of micro-organisms. 

Select a transportation mode to minimize risks to the extent practicable. Drums, ISO tanks, tank trucks, rail tank cars, barges, and pipelines offer tradeoffs in inventory, container integrity, size of potential incidents, distance from supplier or customer, and the frequency of incidents. 

A new job or task with no accident history or information about its potential for incidents. Many incidents occur in a job or task where the employee is not accustomed to the job. 

After you record the steps of the job, review each step to determine the hazards that exist or that might occur. There are several ways to identify job hazards evaluate the ways human error might contribute to a hazard, record the types of potential incidents and the physical agents involved, and make sure that procedures are clearly written. 

Societal Risk - This represents a measure of the risk to a group of people, including tlie risk of incidents potentially affecting more tlian one person. Individual risk (see above) is generally not significantly affected by the number of people involved in an incident. The risk to a person at a particular location depends on tlie probability of occurrence of the luizardous event, and on the probability of an adverse imptict at that location should the event occur. 

Likelihood estimation, sometimes called frequency estimation, cluuactcrizes the probability of occurrence for each potential incident considered in tlie iiiuilysis. The major tools used for likelihood estimation are listed below. ... 

Cause-consequence analysis serx es to characterize tlie physical effects resulting from a specific incident and the impact of these physical effects on people, the environment, and property. Some consequence models or equations used to estimate tlie potential for damage or injury are as follows Source Models, Dispersion Models, Fire Explosion Models, and Effect Models. Likelihood estimation (frequency estimation), cliaractcrizcs the probability of occurrence for each potential incident considered in tlie analysis. The major tools used for likelihood estimation are as follows Historical Data, Failure sequence modeling techniques, and Expert Judgment. 

Describe the potential incidence of allergic and pseudoallergic drug reactions and why it is difficult to obtain accurate numbers. 

Those that reduce the scale of a potential incident such as measures for fire protection, and fixed fire fighting equipment. 

Figure 23-1 shows the hazards identification and risk assessment procedure. The procedure begins with a complete description of the process. This includes detailed PFD and P I diagrams, complete specifications on all equipment, maintenance records, operating procedures, and so forth. A hazard identification procedure is then selected (see Haz-ard Analysis subsection) to identify the hazards and their nature. This is followed by identification of all potential event sequences and potential incidents (scenarios) that can result in loss of control of energy or material. Next is an evaluation of both the consequences and the probability. The consequences are estimated by using source models (to describe the... 

Whether or not environmental stress contributes to the potential incidence or escalation of conflict depends heavily upon the perception of the actors. If environmental stress has an impact on physical or economic well-being, actors are more willing to escalate the potential for conflict. 

The potential incidence of conflict is high in the presence of political instability... 

The assessment of risk of the potential incidence or escalation of conflict is called integrated because of the broad scale of factors that are considered (political, economic, social, demographic and environmental. The integrated risk assessment manages the complexity in the relationship between the consequences of stress and inhibiting or facilitating factors in order to determine which factor has the most potential impact on the incidence or escalation of conflict.

The purpose of layout and spacing is to design a workplace that will minimize personnel injuries, overall property damage, and related business interruption resulting from potential toxic releases, fires, and explosions. Areas to address during layout and spacing include both those that will minimize the incident size and those that will minimize the incident impact. The magnitude of a potential incident may be reduced by ... 

From many companies perspectives, classification by severity is the most common classification system used to establish when to investigate an incident and who should be on a team. The main disadvantage with using severity alone to establish team membership is that it does not consider the potential loss from the occurrence, such as that with a high potential incident. In addition, the complexity of the system involved should also be used to determine team composition as more complex systems might require a larger team to understand the data. 

Regardless, the classification system should achieve a specific outcome and add value. To achieve this goal, companies should consider developing a classification scheme that helps establish the proper team composition based on the complexity, nature, and severity of the occurrence. Chapter 7 describes considerations for building a team based on classification of an incident. The chapter defines terms such as minor incidents, limited impact incidents, significant incidents, high-potential incidents (HIPO), and catastrophic incidents.

High potential incidents—An occurrence that, under different circumstances, might easily have resulted in a catastrophic loss. 

A high potential incident is an occurrence that under different circumstances might easily have resulted in a catastrophic loss. An example could involve the early discovery of an instrument malfunction (by a diligent operator) that might otherwise have resulted in a process upset and violent explosion. 

High potential incidents must be investigated by a complete team with the full rigor of a catastrophic incident as shown in the next section. 

The quantitative evaluation of expected risk from potential incident scenarios. It examines both consequences and frequencies, and how they combine into an overall measure of risk. The CPQRA process is always preceded by a qualitative systematic identification of process hazards. The CPQRA results may be used to make decisions, particularly when mitigation of risk is considered. 

Process-Related Incident— An incident with impact, or potential impact, on process, equipment, people, and the environment. The incident could he internal or external to the process. An occupational incident can result from a process related incident. 

Every incident and potential incident involving reactive chemicals will be investigated and reported, including causes and corrective actions.

Thus, the amount of gas being released during a reaction or decomposition is an important element for the assessment of the severity of a potential incident. 

Traditionally, risk is defined as the product of the severity of a potential incident by its probability of occurrence. Hence, risk assessment requires the evaluation of both the severity and the probability. Obviously, the results of such an analysis aid in designing measures for the reduction of the risk (Figure 3.1). The question that arises now is What do severity and probability mean in the case of thermal risks inherent to a particular chemical reaction or process ...
