Process
Are all accidents preventable??◦ “Event without Causes?”◦ “Unplanned & Uncontrolled?”
Loss?
Definition of an Accident◦ Unwanted or undesired event which results in
physical harm and/or property damage (Vincoli)◦ An accident is a specific, unexpected, unusual and
unintended external action which occurs in a particular time and place, with no apparent and deliberate cause but with marked effects
What does the theory state? What are the pro’s, cons, current perceptions about the theory?◦ Domino Theory◦ Safety Pyramid◦ Unsafe Acts versus Unsafe Conditions◦ Multiple Causation Theories◦ Pure Chance Theory◦ Energy Transfer Theories
How can these accident causation theories aid an accident investigation?◦ Domino Theory- Heinrich (1931)
◦ Safety Pyramid- Heinrich, see also Bird
◦ Unsafe Acts versus Unsafe Conditions (Petersen, mgt problem w/ each hazard)
◦ Multiple Causation Theories (grouped into behavioral and environmental)
◦ Pure Chance Theory (what happens if people believe this?)
◦ Energy Transfer Theories every change of energy there is a source, a path and a receiver
◦ Is there any ONE theory which should be used?
Let’s discuss this!
*difference between a program and a procedure?
Written Clear Concise instructions What to do When to do it
Inside the organization?◦ Who?
Outside investigators?◦ Who?
(See Vincoli pg 57-62)
What are the rolls of those people?
Which accidents should be investigated?
Report the accident occurrence to a designated person within the organization
Provide first aid and medical care to injured person(s) and prevent further injuries or damage
Investigate the accident Identify the causes Report the findings Develop a plan for corrective action Implement the plan Evaluate the effectiveness of the corrective action Make changes for continuous improvement
Disclaimer-huge subject! Just touching tonight
Is it a “cause” or a “symptom?”
