Analysis accident/incident

Most companies have an accident/incident analysis process that identifies the proximal failures that led to an incident, for example, a flawed design of the pressure relief valve in a tank. Typical follow-up would include replacement of that valve with an improved design. On top of fixing the immediate problem, companies should have procedures to evaluate and potentially replace all the uses of that pressure relief valve design in tanks throughout the plant or company. Even better would be to reevaluate pressure relief valve design for all uses in the plant, not just in tanks.

BBS cannot be viewed as the panacea or end-all solution for the prevention of accidents/ incidents, but only as one tool in the arsenal of tools, and it does not supplant a complete and organized overall approach in addressing occupational safety and health issues of today. All the components discussed in this book must be in place, such as training, safety and health program, accident/incident analysis, safety engineering, controls, interventions, etc. It is only then that BBS can become an integral part of the occupational safety and health initiative. 

This chapter has adopted a broad perspective on data collection and incident analysis methods. Both qualitative and quantitative aspects of data collection have been addressed, and data collection approaches have been described for use with large numbers of relatively low-cost incidents or infrequently occurring major accidents.

Incident causation is assumed to progress from the bottom to the top, which means that chances for early prevention of accidents decrease as you get closer to the top. The order of incident analysis is assumed to be top-down, but with different starting points in the iceberg depending On the type (or level) of data that trigger the detection in the first place. It is also assumed that modem investigation techniques will always try to get as far to the bottom of...

Thorough and effective analyses of workplace incidents are critical components of a comprehensive safety management system. Yet, many incident analysis processes (i.e., accident investigations) fall short. They frequently fail to identify and resolve the real root causes of injuries, process incidents and near misses. Because the true root causes of incidents are within the system, the system must change to prevent the incident from happening again. 

This assumption is one of the most pervasive in engineering and other fields. Hie problem is that it s not true. Safety and reliability are different properties. One does not imply nor require the other A system can be reliable but unsafe. It can also be safe but unreliable. In some cases, these two properties even conflict, that is, making the system safer may decrease reliability and enhancing reliability may decrease safety. The confusion on this point is exemplified by the primary focus on failure events in most accident and incident analysis. Some researchers in organizational aspects of safety also make this mistake by suggesting that high reliability organizations will be safe [107,175,177,205,206]. 

The causality model used in accident or incident analysis determines what we look for, how we go about looking for facts, and what we see as relevant. In our experience using STAMP-based accident analysis, we find that even if we use only the information presented in an existing accident report, we come up with a very different view of the accident and its causes. 

A safety professional is a person engaged in the prevention of accidents, incidents, and events that harm people, property, or the environment. They use qualitative and quantitative analysis of simple and complex products, systems, operations, and activities to identify hazards. They evalnate the hazards to identify what events can occur and the likelihood of occnrrence, severity of results, risk (a combination of probability and severity), and cost.

MORT Safety Assurance Systems by WilMam G. Johnson This text serves well both for incident causation model building and for incident investigation. The accident investigation chapter states that while accident investigation has always been a major element in safety, pre-accident hazard analysis is preferable (p. 347). 

In Japan, analysis of medical incidents is focused on over the past decade, due to an accident at Yokohama City University Hospital (Hashimoto, 2003). This means that incident analysis in this field is just getting started compared with other industries, such as nuclear power, chemical, and aviation industry. In other words, less knowledge on incident analysis has been accumulated in this field. 

Again, to eliminate accidents and injuries at your company, you need to figure out what is causing them. To determine the leading causes over time, you need to develop a recordkeeping and incident analysis system.

National Safety Council (NSC) For several decades, the National Safety Council (NSC) has compiled data on accidents, incidents, injuries, illnesses, and deaths. An annual publication provided detailed analysis of the data. For many years the publication title was Accident Facts. More recently, the title is Injury Facts. This publication breaks down data and analysis into three groups occupational, motor vehicle, and home and community. Also the publication now reports information on intentional injuries, such as assaults and self-harm. Data come from a variety of sources.
