Safety flowchart

Sometimes it is easiest to prepare a general flowchart that identifies events which may occur at a facility during an incident. This flowchart can identify possible avenues the event may lead to and the protection measures available to mitigate and protect the facility. It will also highlight deficiencies. The use of a flowchart helps the understanding of events by personal unfamiliar with petroleum risk and safety measures. It portrays a step by step scenarios that is easy to follow or explain. Preparation of in-depth risk probability analysis can also use the flowchart as the basis of the event trees or failure modes and effects. Figure 3 provides a generic example of a typical hydrocarbon process facility Safety Flowchart. API Recommended Practice RP 14C provides an example of a Safety Flowchart for an offshore production facility. 

A safety review method by which What-If investigative questions (i.e., brainstorming or checklist approach) are asked by an experienced and knowledgeable team of the system or component under review where there are concerns about possible undesired events. Recommendations for the mitigation of identified hazards are provided. See also Brainstorming Hazard and Operability Stndy (HAZOP) Safety Flowchart.

Figure 5 is an example of a decision tree you may find useful when considering QRA for particular process safety applications. The decision tree illustrates a flowchart of questions you can ask yourself (or others) to decide how far through the process of risk analysis to go to satisfy a need for increased risk understanding. 

As the Figure 4.1 flowchart implies, managing chemical reactivity hazards starts with a management system. To prevent incidents, a facility must not only be well designed, but also properly operated and maintained. A commitment to safety from all levels of management is essential, to ensure that all safety aspects receive adequate priority. In practice, conflicts of interest may arise between safety and other goals such as production demands and... 

A flowchart (Figure 1) shows a decision-making flow for the determination and safety assessment of the hazard potential. 

This chapter develops characteristics of high quality recommendations necessary for achieving successful implementation. The first section is a presentation of the major concepts related to recommendations, such as attributes of good recommendations, management of change, and inherent safety. The second section expands on the attributes and presents a systematic discussion of the flowchart for recommendations.

Some people are also very concerned about the potential environmental effects of aquaculture operations. A USDA advisory committee on aquatic biotechnology and environmental safety recently drew up a set of performance standards and logic flowcharts for safely conducting research with genetically modified fish and shellfish (ABRAC). This effort was especially noteworthy because it enjoyed the collective support of the aquatic research community, private industry, environmental interest groups, and state natural resource officials. 

Regulation 11 in the Pipelines Safety Regulations (1996) requires that the operator shall ensure that no fluid is conveyed in a pipeline unless the safe operating limits of the pipeline have been established. In order to meet this requirement, inspections will be carried out and analyses undertaken in order to determine the maximum allowable operating pressure (MAOP) for the subsea pipeline. Typically, the process for such an assessment will be undertaken in a manner as described by Hopkins et al. (2001) and shown in a flowchart in Figure 1.4. This process shows the progressive... 

In short, the accident risk assessment provides a comprehensive, detailed evaluation of the overall accident risk associated with the operation and maintenance of a specific facility, including its systems, equipment, and hardware. It incorporates the results of integrated hazard analyses, recommended design changes, hazard reports, and procedural or administrative tools that will eliminate or reduce the risk of these hazards, operational flowcharts, safety-critical procedure lists, and other such information pertinent to overall assessment of accident risk. 

Software Preliminary Hazard Analysis This type of analysis is used to identify software program routines that are considered to be safety-critical, and thus is conducted prior to software program coding. To perform the analysis, the analyst should make reference to any available system specifications, interface documentation, functional flow diagrams, software flowcharts, storage and file allocation specifications, and any other program descriptive information. 

Figure E.l represents the simple flow of the system safety process and provides a graphic summary of the materials presented in this text. This flowchart shows the typical functions of the system safety life cycle.
