Hazard analysis overview

The handbook additionally provides an extensive overview and comparison of commercially available computer systems and software for chemical emergency planning. This section provides technical guidance for hazard analysis and identification implementing regulatory requirements and descriptions of computer applications and systems applicable under SARA Title III. 

In the process of identifying chemical health hazards, tlie near term and long tenn fate of tlie hazard should be incorporated into tlie analysis. Near-term concerns relate primarily to tlie release of the chemical into the enviromnent. This leads to the general subject area of e.xposure assessment, including routes of e.xposure - a topic that is treated in e.xtensive detail in Cliapter 12. However, tlie fate of the chemical (hazard) following tlie point of human entry is another consideration when attempting to identify health hazards. An overview of tliis topic is presented here...

A number of hazard identification and analysis techniques (e.g., HAZOP), can be applied to identify, analyze, and reduce and/or mitigate the process hazards, which includes handling of reactive chemicals and energetic reactions. Chapter 4 provides an overview of these kinds of techniques as related to reactive chemicals mote detailed reviews of hazards analysis techniques are included in [2,3].

Fire hazard analysis (FHA) is the process to determine the size, severity, and duration of a scenario and its impact on personnel, equipment, operations, and the environment. Chapter 5 provided details of performing an FHA. The following paragraphs provide an overview of the FHA process. For example, one scenario could be a seal failure where the material being released is ignited and afire results. In assessing consequences, several questions must be considered ...

The Executive Summary provides an overview of why the hazards analysis was carried out, how it was performed and what the major findings of the analysis were. Unless there is a serious incident that requires a close reading of the report, the only section that most people will read is the Executive Summary, therefore, it should be written well.

By way of an overview introduction, the chapter will provide an overall summary of the RMP, discuss the hazard analysis requirements to include consequence analysis, describe the prevention program requirements and the emergency response requirements, and finally discuss the risk management plan. 

Job analysis for training purposes involves a careful study of job tasks. This is a further effort to define the specific content of training—determining what should be the contents of training in terms of what an employee must do to perform a task, job, or assignment in an effective way [4]. It requires an orderly, systematic collection of data (task analysis) about the job. We are familiar with this through our job Hazard Analysis procedures. Refer to Chapter 15 for an overview of Job Hazard Analysis. The following methods are also available for job analysis ... 

Many books and papers, including Process Risk and Reliability Management, explain the various types of hazards analysis techniques that are used. A very brief overview of some of the techniques that are used offshore is provided in this section.

All safety activities refer to an item . An item in terms of ISO 26262 is defined as a system or array of systems to implement a function at the vehicle level, to which ISO 26262 is applied . The Item Definition marks the scope of the Safety Considerations on an overview level and is the starting point of all furflier safety activities. It is, in particular, a necessary preparation for the Hazard Analysis and Risk Assessment (HARA), because in order to identify malfunctions that may lead to scenarios that bear the risk of an accident (called hazards), the interfaces of the investigated system to its environment must be known, as well as the specified behavior at these interfaces. Deviations from this specified behavior constitute the item s failures, a subset of these constituting the hazardous failures. As explained above, CMSs are well-suited to be regarded as an item according to the definition in ISO 26262. So the Item Definition usually depicts the entire CMS with camera(s), processing unit(s) and display(s). 

The remainder of the paper is structured as follows Section 2 gives an overview of relevant parts of the standards VDE 0832 and EN 50556, respectively. Section 3 presents a hazard analysis using HAZOP analysis. Section 4, in turn, introduces the embedded system platform architecture derived from the safety and domain specific requirements. In addition. Section 5 proves the architecture by going through a typical use-case. The main steps within the architecture are highlighted. Finally, Section 6 concludes by summarizing the key facts of the work carried out.
