EFFECTIVE ACCIDENT INVESTIGATION


What is an accident
An accident is the final event in an unplanned process that result in injury or illness to an employee and possibly property damage
Accident types
STRUCK BY
STRUCK AGAINST
 CONTACT BY
CONTACT WITH
CAUGHT ON
CAUGHT BETWEEN
FALL TO SURFACE
FALL TO BELOW
OVER EXERTION
BODILY REACTION
OVER EXPOSURE
CAUSE OF ACCIDENT
Old theory-worker error :says worker makes a choice to work  in an unsafe manner
New theory-system approach : says accidents occur due to multiple causes and due to defects in the systems
Characteristics of effective incident investigation program
Clearly assigned responsibility for accident investigation
All accident investigations will be formally trained on accident investigation techniques
The purpose is to find fact not fault
Dig deep to know hazardous conditions that caused accidents
 report will make the recommendations to correct the hazardous conditions and work practices
Corrective actions must be completed
An annual review of accident reports
Six steps for conducting accident investigation
Secure the accident scene
Conduct interview
Develop the sequence of events
Conduct cause analysis
Determine the solutions
Write the report
DOCUMENTING THE ACCIDENT SCENE
Make personal observations
Take photos of accident scene
Take video clips of the scene
sketch the accident scene
Interview records
Steve’s seven rights of interview process
Be sure you ask the
Right people the
Right question at the
Right time in the
Right place in the
Right way for the
Right reason to uncover the
Right facts
WHO NEEDS TO BE INTERVIEWED
The victim
Co workers
Direct supervisors
Manager
Training department
Personnel department
Maintenance department
Emergency responders
Medical personal
Coroner
Police
The victim’s spouse and family
Effective interviewing techniques
Keep the purpose of investigation in the mind
Approach the investigation with an open mind
Go to the scene
Express concern regarding the accident and desire to prevent a similar occurrence
Tell the interviewee that the information they give is important
Be friendly , understanding and open minded
Be calm and unhurried
Single event theory
An accident is thought to be the result of a single , one time easily identifiable , unusual , unexpected occurrence that result in injury or illness
The domino theory
This describes as a series of related occurences which lead to a final event that results in injury or illness
Multiple cause theory
Accidents are a result of  a series of random related and / or unrelated actions that somehow interact to cause the accident
Four categories of events
Actual events
Assumed events
Non events
Simultaneous events
Developing the sequence of events
Once the sequence of events is developed we will study each event to know:
Hazardous condition
Unsafe behaviors
System weaknesses
Components of an event
Actor:  the actor is an individual or object that directly influenced the flow of the sequence of events
Action is something that is done by the actor
Hazardous conditions
Materials
Machinery
Equipment
Tools
Chemicals
Environment
Workstations
Facilities
People
workload
Levels of cause analysis
Injury analysis
Event analysis
System analysis
Higher priority strategies that control hazards
Elimination
Substitution
Engineering controls

Lower priority strategies to control exposure and behavior
WARNINGS
ADMINISTRATIVE CONTROLS
PERSONAL PROTECTIVE EQUIPMENT
WRITING THE REPORT
Background
Description
Findings
Recommendations
