Hazard Evaluation Process Chart

The MORT chart contains detailed information to aid in evaluating the hazard analysis process (HAP) and the design effort. In practice, however, the MORT tools and techniques that are most frequently used are in the areas of accident investigation, auditing, appraisal, and p>erformance monitoring. 

The preparation of a matrix and the subsequent evaluation of the hazards identified can lead to a qualitative judgment of process risk and to the identification of available pathways to reduce that risk. Software is available to assist in making and maintaining interactionlike matrices. One example is a database shell called CHEMPAT (AIChE, 1995). When CHEMPAT is customized by the user, a compatibility chart is produced based on user-supplied chemical information. 

Any situation, process, materiaL or condition that, on the basis of applicable data, can cause a fire or explosion or provide a ready fuel supply to augment the spread or intensity of a fire or explosion and that poses a threat to life, property, continued business operation, or the enviromnent. The relative degree of hazard can be evaluated and appropriate safeguards provided. According to the Bureau of Labor Statistics Census of Fatal Occupational Injuries Charts, 1992-2007, fires and explosions accounted for 3 percent of workplace fatalities in 2007.

Bow-Tie Analysis (BTA) a type of qualitative process hazard analysis.The methodology is an adaptation of three conventional system safety techniques Fault Tree Analysis, Causal Factors Charting, and Event Tree Analysis. Existing safeguards (barriers) are identified and evaluated for adequacy...
