1.10 HAZARD IDENTIFICATION

Posted by The Berozgaar on July 03, 2017 No comments
If hazards are identified, chances of occurrence of accident can be minimized. What is hazard – It is a workplace condition which exists or can be caused in combination with other variables, which has the potential for accidents, serious injuries, disease, and/or property damage. With hazard identification, the safety programmes and records can be improved. Examination of accident and injury records often points the way to where the efforts should be focused.

Hazard identification analysis is a very careful study of all the components of a work system in order to detect problems, to understand the relationship between the system and the problem in order to eliminate the problem and its potential consequences.

There are several methods for hazard identification, each having its own contribution for specific tasks and hazard analysis. Most commonly used methods are:

        1.   Preliminary hazard analysis. It serves as a guide for more in-depth analysis as more information becomes available. It focuses on what is already known about the product, process, or change to be made. It consists of formulating a list of hazards and asking simple questions in the form of what-if...?

                2.  Failure mode and effects analysis. It is adopted for safety analysis from reliability analysis of complex system. System is broken down into all its components and systematic evaluation of how components might fail, and what the effects of these failures might be, is done. This analysis requires a criticality rating for each failure mode depending on the degree of hazard posed by the failure. This method has demerit of not examining the linkage of components and the potential of human errors.

                               3.    Hazard and operability review (HAZOP). Adopted widely by chemical plants to identify operation problems, HAZOP uses brainstorming techniques, encouraging involvement and innovation, and generates ideas for solutions.

                             4.     Fault tree analysis. A deductive reasoning technique which assumes an undesirable event and proceeds in a logical manner to examine events or combinations of events which must precede the occurrence of the top event. It provides a graphic model that displays the various combinations of equipment faults and/or failures that can cause the top event. Such analysis is possible with complete and comprehensive understanding of the system/plant operation and various equipment failure modes.

                   Safety Programmes
               The three phases of safety programmes are
                     1.            Safety awareness. Educational on job instructional training, behavior, ergonomics, job safety analysis techniques.
                 2.            Safety implementation. By all concerned.
                 3.            Safety programme preservation. To maintain enthusiasm and energy levels which do not deteriorate with time.
