An Accident is:
• a. An unexpected and undesirable event, especially one
resulting in damage or harm: car accidents on icy roads.
• b. An unforeseen incident: A series of happy accidents led
to his promotion.
• c. An instance of involuntary urination or defecation in
one's clothing.
• 2. Lack of intention; chance: ran into an old friend by

Hazard
• Existing or Potential
Condition That
Alone or Interacting
With Other Factors
Can Cause Harm
• A Spill on the Floor
• Broken Equipment
Risk
• A measure of the probability and
severity of a hazard to harm human
health, property, or the environment
• A measure of how likely harm is to
occur and an indication of how serious
the harm might be
Risk  0

Human Behavior
Common to
all accidents
Not limited to person
involved in accident
Human Factors
• Omissions &
Commissions
• Deviations from
SOP
– Lacking Authority
– Short Cuts
– Remove guards
Human Behavior is a function of :
Activators (what needs to be done)
Competencies (how it needs to be done)
Consequences
(what happens if it is/isn’t done)
ABC Model
Antecedents
(trigger behavior)
Behavior
(human performance)
Consequences
(either reinforce or punish behavior)
Only 4 Types of
Consequences:
•Positive Reinforcement (R+)
("Do this & you'll be rewarded")
•Negative Reinforcement (R-)
Behavior
("Do this or else you'll be penalized")
•Punishment (P)
("If you do this, you'll be penalized")
•Extinction (E)
("Ignore it and it'll go away")
Consequences Influence
Behaviors Based Upon
Individual Perceptions of:
• Significance
Magnitude
Impact
positive
or
negative
 Timing - immediate or future
 Consistency - certain or uncertain
Human Behavior
• Behaviors that have consequences that are:
• Soon
• Certain
• Positive
Have a stronger effect on people’s behavior
Some examples of Consequences:
Why is one sign often ignored, the
other one often followed?
Human Behavior
• Soon
• A consequence that follows soon after a
behavior has a stronger influence than
consequences that occur later
• Silence is considered to be consent
• Failure to correct unsafe behavior
influences employees to continue the
behavior
Human Behavior
• Certain
• A consequence that is certain to follow a
behavior has more influence than an
uncertain or unpredictable consequence
• Corrective Action must be:
– Prompt
– Consistent
– Persistent
Human Behavior
• Positive
• A positive consequence influences
behavior more powerfully than a
negative consequence
• Penalties and Punishment don’t work
• Speeding Ticket Analogy
Human Behavior
• Example: Smokers find it hard to stop
smoking because the consequences are:
A) Soon (immediate)
B) Certain (they happen every time)
C) Positive (a nicotine high)
The other consequences are:
A) Late (years later)
B) Uncertain (not all smokers get lung cancer)
C) Negative (lung cancer)
Deviations from SOP
• No Safe Procedure
• Employee Didn’t know Safe Procedure
• Employee knew, did not follow Safe
Procedure
• Procedure encouraged risk-taking
• Employee changed approved procedure
Human Behavior
• Thought Question:
What would you do as a worker if you
had to take 10-15 minutes to don the
correct P.P.E. to enter an area to turn off
a control valve which took 10 seconds?
Human Behavior
• Punishment or threatening workers is a
behavioral method used by some Safety
Management programs
• Punishment only works if:
– It is immediate
– Occurs every time there is an unsafe behavior
• This is very hard to do
Human Behavior
• The soon, certain, positive reinforcement
from unsafe behavior outweighs the
uncertain, late, negative reinforcement
from inconsistent punishment
• People tend to respond more positively to
praise and social approval than any other
factors
Human Behavior
• Some experts believe you can change worker’s
safety behavior by changing their “Attitude”
• Accident Report – “Safety Attitude”
• A person’s “Attitude” toward any subject is
linked with a set of other attitudes - Trying to
change them all would be nearly impossible
• A Behavior change leads to a new “Attitude”
because people reduce tension between
Behavior and their “Attitude”
Attitudes
however
Are inside a person’s head -therefore they
are not observable nor measurable
Attitudes can be changed by
changing behaviors
Human Behavior
• “Attention” Behavioral Safety approach
– Focuses on getting workers to pay
“Attention”
– Inability to control “Attention” is a
contributing factor in many injuries
• You can’t scare workers into a safety
focus with “Pay Attention” campaigns
Reasons for Lack of Attention
1. Technology encourages short attention
spans (TV remote, Computer Mouse)
2. Increased Job Stress caused by
uncertainty (mergers & downsizing)
3. Lean staffing and increased workloads
require quick attention shifts between
tasks
4. Fast pace of work – little time to learn
new tasks and do familiar ones safely
Reasons for Lack of Attention
5. Work repetition can lull workers into a loss of
attention
6. Low level of loyalty shown to employees by an
ever reorganizing employer may lead to:
a) Disinterested workers
b) Detached workers (no connection to employer)
c) Inattentive workers
Human Behavior
• Focusing on “Awareness” is a typical
educational approach to change safety
behavior
• Example: You provide employees with a
persuasive rationale for wearing safety
glasses and hearing protection in certain
work areas
Human Behavior
Developing Personal Safety Awareness
A) Before starting, consider how to do job safely
B) Understand required P.P.E. and how to use it
C) Determine correct tools and ensure they are in good
condition
D) Scan work area – know what is going on
E) As you work, check work position – reduce any strain
F) Any unsafe act or condition should be corrected
G) Remain aware of any changes in your workplace – people
coming, going, etc.
H) Talk to other workers about safety
I) Take safety home with you
Human Behavior
Some Thought Questions:
1. Do you want to work safely?
2. Do you want others to work safely?
3. Do you want to learn how to prevent
accidents/injuries?
4. How often do you think about safety as you
work?
5. How often do you look for actions that
could cause or prevent injuries?
Human Behavior
•
More Thought Questions:
a) Have you ever carried wood without wearing gloves?
b) Have you ever left something in a walkway that was a
tripping hazard?
c) Have you ever carried a stack of boxes that blocked your
view?
d) Have you ever used a tool /equipment you didn’t know how
to operate?
e) Have you ever left a desk or file drawer open while you
worked in an area?
f) Have you ever placed something on a stair “Just for a
minute”?
g) Have you ever done anything unsafe because “I’ve always
done it this way”?
Human Behavior
TIME!
“All this safety stuff takes time doesn’t it”?
“I’m too busy”!
“I can’t possibly do all this”!
“The boss wants the job done now”!
Human Behavior
• Does rushing through the job, working quickly
without considering safety, really save time?
• Remember – if an incident occurs, the job may
not get done on time and someone could be
injured – and that someone could be YOU!!

They should meet as often as necessary
This will depend on volume of production and
conditions such as
• Number of employees
• Size of workplace covered
• Nature of work undertaken on site
• Type of hazards and degree of risk
Meetings should not be cancelled
Safety Committees
The Goal of the committee is to facilitate a safe
workplace
Objectives that guide a committee towards the goal include:
Motivate, educate and train at all levels to ID, Reduce, &
Avoid Hazards
Incorporate safety into every aspect of the organization
Create a culture where each person is responsible for
safety of self and others
Encourage and utilize ideas from all sources
Four points to Remember:
•Communication: Must be a loop system
•Dedication:
From everyone
•Partnership:
Between Management
and Employees
•Participation:
An important part of
team working.

• Occupational fatalities
• Lost workday
• Result in light-duty or termination or require medical
treatment (other than first aid) or involve loss of
consciousness or restriction of work or motion
• This information in posted every year from
February 1 to April 30 in the OSHA 300A
Summary
Record Keeping and Updating
• First Aid - one-time treatment that could be
expected to be given by a person trained in
basic first-aid using supplies from a first-aid kit
and any follow-up visit or visits for the purpose
of observation of the extent of treatment
• NOTE: The new OSHA Recordkeeping Rule
lists the specific First Aid Treatments
Immediately Report:
– Any accident that involves: 1. Injury 2. Illness 3.
Equipment or property damage
– Any near-misses.
A near miss is an event that,
strictly by chance, does not result in actual or observable
injury, illness, death, or property damage. Examples:
slips, trips & falls, compressed gas cylinder falling,
overexposures to a chemical
– Any hazards such as:
Exposed electrical wires,
Damaged PPE, Improper material storage, Improper
chemical use, Horseplay, Damaged equipment, Missing
or loose machine guards
HAZARD ANALYSIS
Hazard Analysis
• Orderly process used to determine if a
hazard exists in the workplace
–
–
–
–
Uncover hazards overlooked in design
Locate hazards developed in-process
Determine essential steps of a job
Identify hazards that result from the
performance of the actual job
Step 1: Identify Hazards
HAZARD –
condition with
the potential to
cause personal
injury, death and
property damage
Hazard Identification
• Review Records
• Talk to Personnel
• Accident Investigations
• Follow Process Flow
• Write a Job Safety Analysis
• Use Inspection Checklists
STEP 2: Assess Hazards
• Probability - How likely is the hazard?
– Likely
– Not likely
• Severity - What will happen if
encountered?
– Death
– Serious Injury
– Damage to property
Levels of Risk Awareness
• Unaware: Doesn’t realize at-risk
• Post-Awareness: Realizes Risk After Task
Completion
• Engaged-Awareness: Recognizes Risk While
Performing Task(s) and corrects the situation
• Proactive-Awareness: Foresee Hazards and
Begins Task Only When Safe to Proceed
Who is at Risk?
• Workers
• Visitors
– Invited
• Customers
• Emergency services
• Delivery drivers
– Uninvited
• Trespassers
• Burglars
 Contractors
 Janitorial
 Maintenance
 Others
 Members of Public
 Passers-by
 Neighbors
STEP 3: Make Risk Decisions
What can we do to reduce the risk?
Does the benefit outweigh the risk?

Performing Safety Audits
Guide for Personal Audits
The guide has five steps
• Audit
• React
• Communicate
• Follow up
• Raise standards
Audit
• Get into one of the work areas on a
regular basis
• Develop your own system
• Do not combine a safety audit with other
visits
• Audit must be designed to evaluate safety
• Take notes
React
•
How you react is the strongest element in
improving the safety culture
•
Your reaction tells what is acceptable and not
acceptable
•
You must come away from each inspection with a
reaction:
1. Acceptable because...
2. Not acceptable because...
3. Deteriorated because...
4. Improved because…
Communicate
• In order for the contact to be productive, your
subordinate/co-worker must understand that:
 You inspected his or her area
 You are pleased (or displeased) with what you saw
because of…
 You expect him or her to react to your comments and to
improve
 You will audit the area again in a specified number of
days
Follow Up
• Critical for success of the safety program
• Allows you to demonstrate that it is
important
• Must communicate your assessment to the
employees
Raise Standards
• Will see improvement if the first four
steps are followed
• Keep raising your expectations and help
provide leadership
• Solve the obvious problems then fine tune
the safety and housekeeping efforts
Key Points: Becoming a Good Observer
• Effective observation includes:
Be selective
Know what to look for
Practice
Keep an open mind
Guard against habit and familiarity
Do not be satisfied with general impressions
Record observations systematically
Observation Techniques
To become a good observer, a person
must:
• Stop for 10 to 30 seconds before entering an
area to ascertain where employees are
working
• Be alert for unsafe practices
• Observe activity -- do not avoid the action
Observation Techniques
• Remember ABBI -- look Above, Below,
Behind, Inside
• Develop a questioning attitude
• Use all senses
• sight
• hearing
• smell
• touch
Inspections and Field
Observations
• Use a checklist
• Ask questions
• Take notes
• Respect lines of communication
• Draw conclusions
Unsafe Acts
• Conduct that unnecessarily increases the
likelihood of injury
• All safety rule and procedure violations
are unsafe acts
• All unsafe acts should be corrected
immediately
Unsafe Conditions
• An unsafe condition is a situation, not
directly caused by the action or inaction
of one or more employees, in an area that
may lead to an incident or injury if
uncorrected
• Unsafe conditions are normally beyond
the direct control of employees in the
area where the condition is observed
Audit Practices
• Concentrate on people and their actions
because actions of people account for more
than 96 percent of all injuries
 When to audit
 Where to audit
 How much to audit
 Auditing contractors
Management Commitment
Should Management Consider Safety as a Priority
in Conducting Business

ACCIDENT
INVESTIGATION
INTRODUCTION
• Thousands of accidents occur throughout the
United States every day
• Accident investigations determine how and why
these failures occur
• Conduct accident investigations with accident
prevention in mind - Investigations are NOT to
place blame
• Investigate all accidents regardless of the extent
of injury or damage
THE ACCIDENT
WHAT IS AN ACCIDENT?
THE ACCIDENT
An
unplanned and unwelcome event
that interrupts normal activity
Accidents are What Happens to
Somebody Else
BUT REMEMBER:
YOU
are somebody else
to somebody else
THE ACCIDENT
MINOR ACCIDENTS:
• Such as paper cuts to fingers or dropping
a box of materials
THE ACCIDENT
MORE SERIOUS ACCIDENTS
• Such as a forklift dropping a load or
someone falling off a ladder
THE ACCIDENT
• Accidents that occur over an extended
time frame:
– Such as hearing loss or an illness resulting
from exposure to chemicals
THE ACCIDENT
NEAR-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!
THE ACCIDENT
ACCIDENTS HAVE TWO THINGS IN
COMMON
THE ACCIDENT
They all have outcomes from the accident
THE ACCIDENT
They all have contributory factors that
cause the accident
OUTCOMES OF ACCIDENTS
• NEGATIVE Results
–
–
–
–
–
–
Injury & possible death
Disease
Damage to equipment & property
Litigation costs, possible citations
Lost productivity
Morale
OUTCOMES OF ACCIDENTS

Change to safety programs
Change to procedures
Change to equipment design
ACCIDENT INVESTIGATION
• Accidents are usually complex
• An accident may have 10 or more events
that can be causes
• A detailed analysis of an accident will
normally reveal three cause levels:
–
direct
–
indirect
–
root
Direct Cause
• An accident results only when a person
or object receives an amount of energy
or hazardous material that cannot be
absorbed safely - This energy or
hazardous material is the DIRECT
CAUSE of the accident
The direct cause is usually the result of one or
more unsafe acts or unsafe conditions or both
Indirect and Root Causes
• Unsafe acts and conditions are the indirect
causes or symptoms of accidents
• Indirect causes are usually traceable to:
–
–
poor management policies and decisions
personal or environmental factors
• Root causes are the actual policies and
decisions by management and the actual
personal and environmental factors of the
workplace
ACCIDENT INVESTIGATION
You Must:
• Conduct a preliminary investigation
for:
– serious injuries with immediate
symptoms
• Document the investigation findings
ACCIDENT INVESTIGATION
• Do Not move equipment involved in a work or
work related accident or incident if :
– A death
– A probable death
– 3 or more employees are sent to the hospital
(WISHA -2)
• Unless, Moving the equipment is necessary to:
– Remove any victims
– Prevent further incidents and injuries
ACCIDENT INVESTIGATION
• Within 8 hours of a work-related incident or
accident you must contact the nearest office of
the OSHA in person or by phone to report
– A death
– A probable death
– 3 or more employees are sent to the hospital
(WISHA -2)
• (OSHA) 1-800-321-6742
• WISHA 1-800-4BE-SAFE (423-7233)
ACCIDENT INVESTIGATION
• Assign witnesses and other employees to
assist OSHA personnel who arrive to
investigate the incident
Include:
– The immediate supervisor
– Employees who were witnesses to the incident
– Other employees the investigator feels are
necessary to complete the investigation
ACCIDENT INVESTIGATION
•Make sure your preliminary investigation
is conducted by the following people:
–
–
–
–
–
A person designated by the employer
The immediate supervisor
Witnesses
An employee representative
Other persons with experience and skills to
evaluate the facts
ACCIDENT INVESTIGATION
A preliminary investigation includes
noting information such as the following:
–Where did the accident or incident
occur?
–What time did it occur?
–What people were present?
–What was the employee doing at the
time?
–What happened during the accident or
incident?
ACCIDENT INVESTIGATION

within 30 days concerning any accident
involving a fatality or hospitalization of 3 or
more employees:
–
–
–
–
–
–
–
Name of the work place
Location of the incident
Time and date of the incident
Number of fatalities or hospitalized employees
Contact person

Why Not Rely On OSHA &
Police To Investigate?
• Focus On Culpability
• Minor Accidents Not
Investigated
• PREVENTION
• Protect Company
Interests
• OSHA Requirements
Investigating Accidents
How to find out what really happened
Why Investigate Accidents?
•
Find the cause
• Prevent similar accidents
• Protect company interests
At which level do we investigate?
Death
Lost Time
Injury
Reportable Injury
Minor Injuries
Near Misses
Action
of
Others
Maintenance
Motivation

Knowledge
Design
Conditions
Acts
Investigation Strategy
• Need For Investigation
• Control the Scene
• Gather Facts
• Analyze Data
• Establish Causes
• Write Report
• Take Corrective Action
Investigative Procedures
• The actual procedures used in a particular
investigation depend on the nature and results
of the accident
• All investigations start with a collection of data
and are followed by analysis of that data
• An investigation is not complete until all data
is analyzed and a final report is completed
The Aim of the Investigation
• The key result should be to
prevent a repeat of the same
accident
• Fact finding:
– What happened?
– What was the root cause?
– What should be done to prevent
repeat of the accident?
The Aim of the Investigation
IS NOT TO:
• Exonerate individuals or management
• Satisfy insurance requirements
• Defend a position for legal argument
• Or, to assign blame

Fact Finding
• Gather evidence from
many sources during an
investigation
• Get information from
witnesses and reports as
well as by observation
• Don’t try to analyze data
as evidence is gathered
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
Any other possible evidence
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)
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
Photographs
•
•
•
•
•
Unbiased Recording
Keep Log of Photos
Overall to Close-up
Color if possible
Supplement with Video
Gather Data
• Data includes:
–
–
–
–
–
Persons involved
Date, time, location
Activities at time of accident
Equipment involved
List of witnesses
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?
Documents
• Collect All Related Documents
–
–
–
–
–
–
–
Inspection Logs
Policy & Procedures Manual
JSA (Job Safety Analysis)
Equipment Operations Manuals
Insurance Records
Employee Records
Police Reports
Those who do not know the
past are destined to:
Repeat
Repeat
Repeat

Repeat
Repeat
It.
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
NORMS OF OBJECTIVITY
Objective
Not an Interpretation - Based on
a factual description.
Observable - Based on what is seen
or heard.
Reliable - Two or more people
independently agree on what they
observed.
Measurable - A number is used to
describe behavior or situation.
Specific - Based on detailed
definitions of what happened.
Subjective
Interpretations - Based on
personal
interpretations/biases.
Non-observable - Based on
events not directly observed.
Unreliable - Two or more
people don’t agree on what
they observed.
Non-Measurable - A
number isn’t used.
General - Based on nondetailed descriptions.
INVESTIGATION TRAPS
• Put your emotions aside!
– Don’t let your feelings interfere stick to the facts!
• 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
Record Evidence
• Keep All Notes in Bound Notebook
• Include Date - Time - Place – Vantage Point
• Keep Originals
• Rewrite in Report Form
Samples
• Collect Perishables
First
• Fluids
• Open Containers
• Filings
• Chemicals
• Air
Interviews
• Experienced personnel should conduct
interviews
• If possible the team assigned to this task
should include an individual with a legal
background
• After interviewing all witnesses, the team
should analyze each witness' statement
Interviews
• Analyze this information along with data
from the accident site
• Not all people react in the same manner
to a particular stimulus
• A witness who has had a traumatic
experience may not be able to recall the
details of the accident
• A witness who has a vested interest in the
results of the investigation may offer
biased testimony
Interviews
• Excellent Source of first hand knowledge
• May Present Pitfalls in form of:
–
–
–
–
Bias
Perspective
Embellishment
Omissions
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
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
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
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
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?”
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
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
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
Ask All Witnesses
•
•
•
•
•
•
Name, address, phone number
What did you see?
What did you hear?
Where were you standing/sitting?
What do you think caused the accident?
Was there anything different today?
Ask Supervisors
• What is normal procedure for activities
involved in the accident?
• What type of training persons involved in
accident have had?
• What, if anything was different today?
• What they think caused the accident?
• What could have prevented the accident?

material and other information collected
at the scene
• Determine a clear picture of what
happened
• Formally document sequence of events
CONTRIBUTING FACTORS
INVESTIGATION STRATEGY
• INVESTIGATION TEAM
•
EVALUATES ALL FACTORS CONCERNED
•
ISOLATES THE KEY FACTOR(S) BY
ASKING THE FOLLOWING QUESTION....
•
WOULD THE ACCIDENT HAVE HAPPENED
IF THIS PARTICULAR FACTOR WAS NOT
PRESENT?
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)
• Training
• Was employee trained - when, by whom,
documentation
Indirect Causes
• Unsafe conditions – what material
conditions, environmental conditions and
equipment conditions contributed to the
accident
• Unsafe Acts – what activities contributed
to the accident
Breakdown of Unsafe Conditions
• Inadequately guarded or
unguarded equipment
• Defective tools, equipment or
materials
• Fire and explosion hazard
• Unexpected movement hazard
• Projection hazards
Breakdown of Unsafe Conditions
• Housekeeping
• Hazardous environmental conditions
• Improper ventilation
• Improper illumination
• Unsafe dress or apparel
Breakdown of Unsafe Acts
• Operating without authority
• Operating or working at unsafe speeds
• Making safety devices inoperative
• Using unsafe equipment
• Neglecting to wear PPE
• Unsafe loading, placing, mixing, combining
• Taking unsafe position or posture
Basic Causes
• Management
Systems & Procedures
• Environment
• Equipment
• Human Behavior
Design & Equipment
Management
•
•
•
•
•
•
Was a hazard assessment conducted?
Were the hazards recognized?
Was control of the hazards addressed?
Were employees trained?
Did supervision detect/correct deviations?
Was Supervisor trained in job/accident
prevention?
• What were the production rates?
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?
Contribution of Safety
Controls such as:
• Engineering Controls - machine guards, safety
controls, isolation of hazardous areas,
monitoring devices, etc.
• Administrative Controls - procedures,
assessments, inspection, records to monitor and
ensure safe practices and environments are
maintained.
• Training Controls - initial new hire safety
orientation, job specific safety training and
periodic refresher training.
What controls failed?
• List the specific engineering,
administrative and training controls that
failed and how these failures contributed
to the accident
What controls worked?
• List any controls that prevented a
more serious accident or
minimized collateral damage or
injuries
Determine
• What was not normal before the
accident
• Where the abnormality occurred
• When it was first noted
• How it occurred
Report Causes
• Analysis of the Accident – HOW &
WHY
a. Direct causes (energy sources;
hazardous materials)
b. Indirect causes (unsafe acts and
conditions)
c. Basic causes (management policies;
personal or environmental factors)
Unable to Identify Root Causes
• Timeliness
• Poor development of information
• Reluctance to accept responsibility
• Narrow interpretations of
environmental causes
• Erroneous emphasis on a single cause
• Allowing solutions to determine causes
• Wrong person(s) investigating
PREPARE A REPORT
• Accident Reports should contain
the following:
– Description of incident and injuries
– Sequence of events
– Pertinent facts discovered during
investigation
– Conclusions of the investigator(s)
– Recommendations for correcting
problems
PREPARE A REPORT, (CONT.)
• Be objective!
– State facts
– Assign cause(s), not blame
– If referring to an individual’s actions, don’t
use names in the recommendation
• Good: All employees should…….
• Bad: George should……..
Recommendations
• Action to remedy
– Basic causes
– Indirect causes
– Direct causes
• Recommendations - as a result of the finding is
there a need to make changes to:
– Employee training?
– Work Stations Design?
– Policies or procedures?
Recommendations
• Consider
-Effectiveness
-Cost
-Feasibility
-Effect on Productivity
-Time to Implement
-Employee Acceptance
-Management Acceptance
Accepting Inadequate Reports
• There is no surer way to destroy a
program's effectiveness than to accept
substandard work
• This immediately sends a signal to
subordinates that accident investigation
is not a high priority and does not receive
significant attention from management
Common Problems
• Accidents not reported
• Unable to identify basic causes
• Accepting inadequate reports
• Neglecting to implement corrective
actions
Accidents Not Reported
• Nothing is learned from unreported
accidents
• Accident causes are left uncorrected
• Infections and injury aggravations result
• Neglecting to report tends to spread and
become a common practice
Why Workers Fail to Report
• Fear of discipline
• Concern for reputation
• Fear of medical treatment
• Desire to keep personal record clean
• Avoidance of red tape
• Concern about attitudes of others
• Poor understanding of importance
Combat Reporting Problems
• Indoctrinate new employees
• Encourage workers to report minor accidents
• Focus on accident prevention and loss control
• Be positive
• Discuss past accidents
• Take corrective action promptly
Neglecting to Implement
Corrective Action
• The whole purpose of the investigation
process is negated if management fails to
remedy the causes
• Here again, management sends a signal
to subordinates that it's not important,
and subordinates develop the attitude
that it's an exercise in futility and "why
bother?
Improving the Quality of
Accident Investigation
•
Insist on reporting of all injuries
•
Adopt a well-designed accident report form
•
Train all levels of management
•
Insist on the investigation of all accidents
•
Participate actively in serious accident
investigations
Improving the Quality of
Accident Investigation
• Review and comment
• Refuse to accept inadequate reports
• Establish controls to follow up on corrective
actions
• Be responsive to recommendations
• Hold responsible persons accountable
• Emphasize that accident investigations are
FACT-finding, not FAULT-finding
• Encourage investigators to challenge the system
Summary
• Most accident investigations follow
formal procedures
• An investigation is not concluded until
completion of a final report
• A successful accident investigation
determines what happened and how and
why the accident occurred
• Investigations are an effort to prevent a
similar or perhaps more disastrous
sequence of events
