Hazard studies history

It has been found that well executed Studies 1 and 2 result in a plant design that is right first time , and reduce the stress and amount of work needed at the HAZOP (Hazard Study 3) stage (see the A brief history of Hazard Studies box-out). [Pg.313]

A brief overview of the history of Hazard Studies, as experienced by one major UK chemical company, may be of help in setting this chapter in context. [Pg.313]

In order to evaluate the spectrum compatibility, the acceleration response spectra of the selected acceleration time histories scaled to average PGA for the area were calculated and compared with the lowest and highest NEHRP spectra obtained from the earthquake hazard study conducted for the area as shown in Figure 3. [Pg.383]

Control of Plant and Process Modifications Many accidents have occurred because plant or process modifications had unforeseen and unsafe side effects (Sanders, Management of Change in Chemical Plants Learning from Ca.se Histories, Butterworth-Heinemann, 1993). No such modifications shoiild therefore be made until they have been authorized by a professionally quahfied person who has made a systematic attempt to identify and assess the consequences of the proposal, by hazard and operability study or a similar technique. When the modification is complete, the person who authorized it... [Pg.2270]

This is important information that describes the site and provides workers, visitors, and other personnel with pertinent site information. In addition to studying job specifications, contracts, and talking with project management, the author(s) should develop a detailed operating history of the site. The history is useful when determining potential site hazards. The type of information that can typically be located includes ... [Pg.76]

Case Studies in Environmental Medicine Taking an Exposure History—The importance of taking an exposure history and how to conduct one are described, and an example of a thorough exposure history is provided. Other case studies of interest include Reproductive and Developmental Hazards Skin Lesions and Environmental Exposures Cholinesterase-Inhibiting Pesticide Toxicity and numerous chemical-specific case studies. [Pg.7]

The study of case histories is important in the area of safety. To paraphrase G. Santayana, one learns from history or is doomed to repeat it. This is especially true for safety anyone working in the chemical industry can learn from case histories and avoid hazardous situations or ignore history and be involved in potentially life-threatening accidents. [Pg.535]

One result of studies on these persons with varying radiation histories has been the development of criteria on the maximum permissible concentrations of radioactivity in air and in water ingested by the population. The criteria factors that determine the hazards of the various radionuclides include ... [Pg.109]

Finally, this effort is not meant to replace those technical studies which have dealt with the analysis and prioritization of known hazardous waste sites where a great deal of specific information is available on site history, contents, and hydrogeology. The present study should reduce the need for expensive drilling and testing programs and provide a means for their rational. implementation. [Pg.57]
