8. The Basics
Accident or Incident?
In the past, the term "accident" was often used
when referring to an unplanned, unwanted
event.
To many, "accident" suggests an event that was
random, and could not have been prevented.
Since nearly all worksite fatalities, injuries, and
illnesses are preventable, OSHA suggests using
the term "incident" investigation.
Source: https://www.osha.gov/dcsp/products/topics/incidentinvestigation/index.htmlIntroduction to Incident Investigation

9. Incident?
Incident: An unplanned,
undesired event that hinders
completion of a task and may
cause injury, illness, or
property damage or some
combination of all three in
varying degrees from minor to
catastrophic.
Unplanned and undesired do
not mean unable to prevent.
Introduction to Incident Investigation

10. What Is An Accident?
Accident: Definition is often similar to
incident, but supports the mindset that it
could not have been prevented
Accident usually means
harm or damage to the
victim.
This can be an issue if you
feel there was no work
related injury

What is the difference between accident and incident?
Does your organization conduct accident investigations for the
same reason as OSHA?

Introduction to Incident Investigation

13. Opportunity
Investigating a
worksite incident— a
fatality, injury, illness,
or close call—
provides employers
and workers the
opportunity to identify
hazards in their
operations and
shortcomings in their
safety and health
programs. Introduction to Incident Investigation

16. Focus
Incident investigations that focus on
identifying and correcting root causes, not
on finding fault or blame, also improve
workplace morale and increase
productivity, by demonstrating an
employer’s commitment to a safe and
healthful workplace.
Introduction to Incident Investigation

17. Root Cause?
Event Date: 01/27/2009
On January 27, 2009, Gerald
Holland was walking across an
aircraft hanger to exit the
building for lunch.
Ice and sleet had been
blowing through gaps in the
hanger doors, creating
slippery conditions on the
adjacent floor.
Gerald slipped and fell,
striking his head on the
concrete floor. He was
hospitalized for severe head
trauma and later died.
Introduction to Incident Investigation

18. Team
Incident investigations are
often conducted by a
supervisor, but to be most
effective, these
investigations should include
managers and employees
working together, since each
bring different knowledge,
understanding and
perspectives to the
investigation.
Introduction to Incident Investigation

19. Neutrality
It is advisable to have the supervisor
responsible for only the incident
report and not the incident analysis
The immediate supervisor of the
injured may be part of the reason
why the incident happened.
The supervisor may, therefore, be
unwilling to identify deficiencies in
training, supervision, discipline, etc.,
for which he or she is responsible.
Introduction to Incident Investigation

20. Attitudes?
He replied "you come in here and point out what's out if compliance and
generally unsafe.
You leave and then management tells us we need to get er' done.
They won't approve any extra equipment for us to get er' done.
They know we have to do things that may not be exactly safe or by policy.
They sit and watch us and know what's going on and then praise us for getting
the job done.
You have got to understand what's really going on here...
They asked us to do the job, they watch us do the job, they praise us for
getting the job done, they give us annual increases for doing the job.
They don't spend money on new equipment or safety items.
Why would we think what we're doing is wrong?
After all, they pay us and the safety department doesn’t.”

22. Conducting
In conducting an incident
investigation, the team must look
beyond the immediate causes of an
incident.
It is far too easy, and often
misleading, to conclude that
carelessness or failure to follow a
procedure alone was the cause of an
incident.

documents/records that
would be reviewed

24. Problem
Those investigations necessarily
start at the bottom, with the
immediate event that caused the
injury.
And, starting at the bottom, the
biggest problem we face is
whether the investigation focuses
on “what went wrong?” or on
“who screwed up?”
If it’s the latter, it’s much harder to
get to root causes, and not just
because witnesses clam up.
The whole investigation gets
skewed. – MW

Introduction to Incident Investigation

26. Root Causes
To do so fails to discover the
underlying or root causes of the
incident, and therefore fails to
identify the systemic changes
and measures needed to prevent
future incidents.
When a shortcoming is
identified, it is important to ask
why it existed and why it was not
previously addressed
Introduction to Incident Investigation

27. OSHA Required?
1910.119(m)
The employer shall investigate each incident which resulted in, or
could reasonably have resulted in a catastrophic release of highly
hazardous chemical in the workplace.
An incident investigation shall be initiated as promptly as possible,
but not later than 48 hours following the incident.
An incident investigation team shall be established and consist of at
least one person knowledgeable in the process involved, including a
contract employee if the incident involved work of the contractor,
and other persons with appropriate knowledge and experience to
thoroughly investigate and analyze the incident.
Introduction to Incident Investigation

28. 1910.119(m)
A report shall be prepared at the conclusion of the investigation which
includes at a minimum:
Date of incident;
Date investigation began;
A description of the incident;
The factors that contributed to the incident; and,
Any recommendations resulting from the investigation.
The employer shall establish a system to promptly address and
resolve the incident report findings and recommendations.
Resolutions and corrective actions shall be documented.

Introduction to Incident Investigation

37. 2014
The only thing Heinrich's Pyramid
gets right (I think) is that
dangerous work practices and
deficient safety controls rarely
cause a fatality every time, so the
death that occurs is often the
result of an activity that has been
repeated, over and over.
But the notion that that same
activity will generate a bunch of
minor injuries and a smaller
group of more serious injuries is
simply wrong
- Michael Wood
Introduction to Incident Investigation

38. What Is An Near Miss?
Unplanned and
unwanted event which
disrupts the work
process OR has the
potential of resulting in
injury, harm, or damage
to persons or property.
Introduction to Incident Investigation

39. Near Miss
The only difference
between most near-miss
experiences and an injury
is timing or a few inches.
Searching for root
causes of near-miss
experiences and
following up with
corrective action will
certainly lead to lower
injury rates.
Introduction to Incident Investigation

40. Near Miss Problems
People don't like to do it.
It's usually inconvenient to fill
out a "near-miss investigation
form.
It's convenient and sometimes
less stressful to just forget the
near miss ever happened.
Who wants to report a
personal experience that
reflects at-risk behavior,
inattention and carelessness,
and maybe an irresponsible
attitude?

a serious injury occurs
before correcting
environmental and
behavioral conditions?

Purpose. Gaining as much
information as possible about
an incident is extremely
important.
Interviewing witnesses is both
a science and an art, and can
make the difference between
a failed or a successful
accident investigation.
Introduction to Incident Investigation

70. INTERVIEWING QUESTIONS
Who?
What?
Where?
Why?
When?
How?
Introduction to Incident Investigation

71. Talk to the Injured
Injured are treated different
from witnesses
Try to get them to write out
the incident in their own
handwriting if possible.
Or have two people witness.
Get their sequences of events.
Employees will be especially
uncooperative if they perceive
that investigations are being
used as a technique to find a
scapegoat.
Do not have the injured
employee fill out reports
beyond what is required by law
420 U.S. 251 (1975), upheld a National
Labor Relations Board (NLRB) decision
that employees have a right to union
representation at investigatory
interviews. These rights have become
known as the Weingarten Rights.

of committing when
communicating with others.
 Did they interrupt often or try
to finish the other person’s
sentences?
 Did they jump to conclusions?
 Were they overly parental and
answer with advice, even
when not requested?
 Did the person appear to make
up their mind before they had all
the information.
 Were they a note taker?
 Did they give any response
afterward?
 Were they impatient?
 Did they exhibit body language
when hearing things they didn’t
agree with?
 Did they change the subject to
something that relates to their
own experiences?
 Did they about the reply while
the other person is speaking than
what he or she is saying.Introduction to Incident Investigation

76. Interview All
Interview all witnesses as
soon as possible
Separate Witnesses
Take signed statements
Too many miss the universe
of people, because they went
home or are on vacation.
Introduction to Incident Investigation

77. Interview Witnesses
Choose a private place to talk
Ask open ended questions
Interview promptly after the
incident
Ask some questions you know

78. Selective Listening
Selective listening is the act of
hearing and interpreting only
parts of a message that seem
relevant to you, while ignoring or
devaluing the rest.
Often, selective listeners will form
arguments before they’ve heard
the full story, making them not
only poor listeners, but poor
speakers too!

90. Why Determine Root Cause?
Prevent problems from recurring
Reduce possible injury to personnel
Reduce rework and scrap
Increase competitiveness
Promote happy customers and stockholders
Ultimately, reduce cost and save money
Introduction to Incident Investigation

91. Look Beyond the Obvious
Invariably, the root cause of a
problem is not the initial reaction or
response.
It is not just restating the Finding
Introduction to Incident Investigation

92. Often the Stated Root Cause
is the Quick, but Incorrect Answer
For example, a normal response is:
Equipment Failure
Human Error
Initial response is usually the symptom, not the root cause
of the problem. This is why Root Cause Analysis is a very
useful and productive tool.
Introduction to Incident Investigation

93. Most Times Root Cause
Turns Out to be Much
More
Such as:
Process or program failure
System or organization failure
Poorly written work instructions
Lack of training
Introduction to Incident Investigation

94. What is Root Cause
Analysis?
Root Cause Analysis is an in-depth
process or technique for identifying
the most basic factor(s) underlying a
variation in performance (problem).
Focus is on systems and processes
Focus is not on individuals
Introduction to Incident Investigation

95. When Should Root Cause Analysis
be Performed?
Significant or consequential events
Repetitive human errors are occurring during a specific process
Repetitive equipment failures associated with a specific process
Performance is generally below desired standard
Introduction to Incident Investigation

96. How to Determine the Real Root
Cause?
Assign the task to a person (team if
necessary) knowledgeable of the
systems and processes involved
Define the problem
Collect and analyze facts and data
Develop theories and possible causes -
there may be multiple causes that are
interrelated
Systematically reduce the possible
theories and possible causes using the
facts
Introduction to Incident Investigation

97. How to Determine the Real Root
Cause? (continued)
Develop possible solutions
Define and implement an action plan
(e.g., improve communication, revise
processes or procedures or work
instructions, perform additional
training, etc.)
Monitor and assess results of the action
plan for appropriateness and
effectiveness
Repeat analysis if problem persists- if it
persists, did we get to the root cause?
Introduction to Incident Investigation

98. Useful Tools For
Determining Root Cause
are:
The “5 Whys”
Pareto Analysis (Vital Few, Trivial Many)
Brainstorming
Flow Charts / Process Mapping
Cause and Effect Diagram
Tree Diagram
Benchmarking (after Root Cause is found)
Some tools are more complex than others
Introduction to Incident Investigation

99. Example of Five Whys for Root Cause Analysis
Problem - Flat Tire
Why? Nails on garage floor
Why? Box of nails on shelf split open
Why? Box got wet
Why? Rain thru hole in garage roof

Actions
In this exercise you’ll
develop and
recommend immediate
actions to correct the
causes of an incident
Develop and write a
recommendation to improve one or
more policies, plans, programs,
processes, procedures, and practices
related to the accident scenario.

113. Preparing a Recommendation
5. What motivates the decision maker?
– Legal obligation
– Fiscal obligation
– Moral obligation
6. Determine cost/benefits of solving the
problem

118. Group Exercise:
Putting it All Together
This exercise will give you practice in
completing using a lot of the information
gained from this course. Be thorough and
use extra paper if needed.
Introduction to Incident Investigation

119. The report is an open document
until all actions are complete!
Follow Up!
Take corrective action
Conduct follow up evaluation
Conduct annual review of reports
Introduction to Incident Investigation

120. Corrective Action
Fix it.
“When they do write a
corrective action they
don't follow it and get it
corrected.”
That is why they continue
to have repeated
accidents.
Introduction to Incident Investigation

121. Example
Walking along a metal grate, a
worker slipped on the loose
grating and fell 31 feet.
Several people knew about
the grate being loose and
never reported it.
There were no mechanisms
to report it as damaged
property.
If it was reported as damaged
property, the accident would
have never happened.
Introduction to Incident Investigation

122. Get Help?
Consider a professional investigator
Seriousness or circumstances of the
accident create the potential for
litigation.
A very high level of knowledge and
experience is necessary to adequately
prepare for legal contingencies.
If legal action is possible, you don't
want an amateur investigation.
A poor investigation could cause more
harm than good.
Introduction to Incident Investigation

123. Litigation?
If litigation is
anticipated, an attorney
should be consulted and
an incident analysis
conducted only if
approved and directed
by the attorney
Attorney Client Privilege
All reports go to the
attorney.

130. Notre Dame Response
Open letter to all by Rev. John Jenkins
“We are conducting an investigation
and we must be careful not to pre-
judge its results, but I will say this:
Declan Sullivan was entrusted to our
care, and we failed to keep him safe.
We at Notre Dame — and ultimately
I, as President — are responsible.
Words cannot express our sorrow to
the Sullivan family and to all
involved.”
It was not our first impulse to go out
and hire a lawyer. That's not the way
we're wired," Barry Sullivan said.

134. Safety Lessons Learned
Physical & System Factors: Glassware cuts are more
common than might be expected and can be very serious.
Root Cause: Broken edge of beaker sliced finger.
Final Actions: Revisit review of glove wear to determine if
heavy gloves should be worn when washing glassware by
hand. Supv QC Lab will purchase, supply, train employees
to wear cut resistant gloves when washing glassware.
Review of chipped glassware inspection program – as
chips weaken glassware and increase the risk of injury.
Reminder to all before working with glassware, always
inspect it for flaws and all glass should be pulled from
service if defects are present.
Review “Safe Handling of Laboratory Glassware”
procedure.
