![Page 6: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/6.jpg)
THE ACCIDENT
MINOR ACCIDENTS:
• Such as paper cuts to fingers or dropping a box of materials.
![Page 7: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/7.jpg)
THE ACCIDENT
• More serious accidents that cause injury or damage to equipment or property:
• Such as a forklift dropping a load or someone falling off a ladder
![Page 8: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/8.jpg)
THE ACCIDENT
• Accidents that occur over an extended time frame:– Such as hearing loss or an illness resulting from
exposure to chemicals
![Page 9: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/9.jpg)
THE ACCIDENTNEAR-MISS
• Also know as a “Near Hit”
• An accident that does not quite result in injury or damage (but could have).
• Remember, a near-miss is just as serious as an accident!
![Page 10: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/10.jpg)

OUTCOMES OF ACCIDENTS
• NEGATIVE ASPECTS– Injury & possible death – Disease– Damage to equipment & property– Litigation costs, possible citations– Lost productivity– Morale
![Page 15: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/15.jpg)
OUTCOMES OF ACCIDENTS
• POSITIVE ASPECTS– Accident investigation– Prevent recurrence– Change to safety programs– Change to procedures– Change to equipment design
![Page 16: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/16.jpg)
The Aim of the Investigation
• The key result should be to prevent a recurrence of the same accident.
• Fact finding:– What happened?– What was the root cause?– What should be done to prevent recurrence?
![Page 17: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/17.jpg)
The Aim of the InvestigationIS NOT TO:
• Exonerate individuals or management.
• Satisfy insurance requirements.
• Defend a position for legal argument.
• Or, to assign blame.
![Page 18: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/18.jpg)

The Investigation
A step-by-step process (almost)
![Page 22: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/22.jpg)
Investigation Strategy
• Gather information• Search for & establish facts• Isolate essential contributing factors• Find root causes• Determine corrective actions• Implement corrective actions
![Page 23: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/23.jpg)
Secure the Scene
• Eliminate the hazards:– Control chemicals– De-energize– De-pressurize– Light it up– Shore it up– Ventilate
![Page 24: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/24.jpg)
Provide Care to the Injured
• Ensure that medical care is provided to the injured people before proceeding with the investigation.
![Page 25: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/25.jpg)
Isolate the Scene
• Barricade the area of the accident, and keep everyone out!
• The only persons allowed inside the barricade should be Rescue/EMS, law enforcement, and investigators
• Protect the evidence until investigation is complete
![Page 26: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/26.jpg)
Ask “What Happened”
• Get a brief overview of the situation from witnesses and victims.
• Not a detailed report yet, just enough to understand the basics of what happened.
![Page 27: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/27.jpg)
Interview Victims & Witnesses
• Interview as soon as possible after the incident– Do not interrupt medical
care to interview• Interview each person
separately• Do not allow witnesses to
confer prior to interview
![Page 28: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/28.jpg)
The Interview• Put the person at ease.
– People may be reluctant to discuss the incident, particularly if they think someone will get in trouble
• Reassure them that this is a fact-finding process only.– Remind them that these facts
will be used to prevent a recurrence of the incident
![Page 29: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/29.jpg)
The Interview
• Take Notes!• Ask open-ended questions
– “What did you see?”– “What happened?”
• Do not make suggestions– If the person is stumbling over a word or
concept, do not help them out
![Page 30: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/30.jpg)
The Interview
• Use closed-ended questions later to gain more detail.– After the person has provided their explanation,
these type of questions can be used to clarify– “Where were you standing?”– “What time did it happen?”
![Page 31: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/31.jpg)
The Interview
• Don’t ask leading questions– Bad: “Why was the forklift operator driving
recklessly?”– Good: “How was the forklift operator driving?”
• If the witness begins to offer reasons, excuses, or explanations, politely decline that knowledge and remind them to stick with the facts
![Page 32: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/32.jpg)
The Interview
• Summarize what you have been told.– Correct misunderstandings of the events
between you and the witness• Ask the witness/victim for
recommendations to prevent recurrence– These people will often have the best solutions
to the problem
![Page 33: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/33.jpg)
The Interview
• Get a written, signed statement from the witness– It is best if the witness writes their own
statement; interview notes signed by the witness may be used if the witness refuses to write a statement
![Page 34: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/34.jpg)
Interview Exercise
• Read the scenario handout• Team up in pairs• One person plays the investigator• One person plays the witness
![Page 35: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/35.jpg)
Gather Evidence
• Examine the accident scene. Look for things that will help you understand what happened:– Dents, cracks, scrapes, splits, etc. in equipment– Tire tracks, footprints, etc.– Spills or leaks– Scattered or broken parts– Etc.
![Page 36: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/36.jpg)
Gather Evidence
• Diagram the scene– Use blank paper or graph
paper. Mark the location of all pertinent items; equipment, parts, spills, persons, etc.
– Note distances and sizes, pressures and temperatures
– Note direction (mark north on the map)
![Page 37: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/37.jpg)
Gather Evidence• Take photographs
– Photograph any items or scenes which may provide an understanding of what happened to anyone who was not there.
– Photograph any items which will not remain, or which will be cleaned up (spills, tire tracks, footprints, etc.)
– 35mm cameras, Polaroids, and video cameras are all acceptable.
• Digital cameras are not recommended - digital images can be easily altered
![Page 38: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/38.jpg)
Review Records• Check training records
– Was appropriate training provided?– When was training provided?
• Check equipment maintenance records– Is regular PM or service provided?– Is there a recurring type of failure?
• Check accident records– Have there been similar incidents or injuries
involving other employees?
![Page 39: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/39.jpg)
ISOLATE FACT FROM FICTION
• Use NORMS-based analysis of information– Not an interpretation– Observable– Reliable– Measurable– Specific
• If an item meets all five of above, it is a fact.
![Page 40: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/40.jpg)
NORMS OF OBJECTIVITYObjective Subjective
Not an Interpretation – Basedon a factual description.
Interpretations – based onpersonal interpretations/biases.
Observable – based on whatis seen or heard.
Non-observable – based onevents not directly observed.
Reliable – Two or more peopleindependently agree on whatthey observed.
Unreliable – Two or morepeople don’t agree on whatthey observed.
Measurable – a number isused to describe behavior orsituation.
Non-measurable – a numberisn’t used.
Specific – based on detaileddefinitions of what happened.
General – based on non-detailed descriptions.
![Page 41: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/41.jpg)
INVESTIGATION TRAPS• Put your emotions aside!
– Don’t let your feelings interfere - stick to the facts! (The Eyes Glazed Over)
• Do not pre-judge.– Find out the what really happened.– Do not let your beliefs cloud the facts.
• Never assume anything.• Do not make any judgements.

CONTRIBUTING FACTORS INVESTIGATION STRATEGY
• ISOLATE ESSENTIAL CONTRIBUTORY FACTORS
– INVESTIGATION TEAM
• ISOLATES THE KEY FACTOR(S) BY ASKING THE FOLLOWING QUESTION....
![Page 49: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/49.jpg)
CONTRIBUTING FACTORS INVESTIGATION STRATEGY
WOULD THE ACCIDENT HAVE
HAPPENED IF THIS PARTICULAR FACTOR WAS NOT PRESENT?
![Page 50: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/50.jpg)
DETERMINE CAUSES• Employee actions
• Safe behavior, at-risk behavior
• Environmental conditions• Lighting, heat/cold, moisture/humidity, dust, vapors, etc.
• Equipment condition• Defective/operational, guards, leaks, broken parts, etc.
• Procedures• Existing (or not), followed (or not), appropriate (or not)

FIND ROOT CAUSES
• When you have determined the contributing factors, dig deeper!– If employee error, what caused that
behavior?– If defective machine, why wasn’t it
fixed?– If poor lighting, why not corrected?– If no training, why not?
![Page 52: Acidentes - Investigação - Cursos](https://reader035.vdocuments.us/reader035/viewer/2022062310/5695d05e1a28ab9b029231a5/html5/thumbnails/52.jpg)
