Q

accident investigation -

A

A structured process of uncovering the sequence of events that produced or had the potential to produce injury, death, or property damage to determine the causal factors and corrective actions.

Q

causal factors -

A

Events and circumstances that produced the accident.
Causal factors incorporate “root causes,” “basic causes,” “immediate causes,” lower level causes, upper level causes, and management causes. When discovering causal factors, it is important to analyze all causes at all levels.

Q

corrective actions -

A

The actions taken to prevent recurrence of the accident.

Corrective actions are the “fixes” to prevent future accidents. These fixes should be performed at the appropriate level.

Q

How Heinrich’s Domino theory works

A

The first domino starts the accident sequence.
An accident occurs by comparing the events leading up to it to a set of dominoes.
The first domino (event) sets the stage and starts the accident sequence. When it falls, it pushes the next, and that pushes the next, until the last domino (accident or injury) is toppled
there are 5 actions that comprise the sequence
*ancestry & social environment
*fault or person
*unsafe act
*unsafe condition

17
Q

Three phases of accident investigation

A

The investigative phase -
the analytical phase
the recommendation phase

18
Q

Three phases of accident investigation - and their definitions

A

investigative - gain knowledge, discover facts, interview, document
analytical - analyze knowledge?What happened?
Recommendation - Develop corrective actions - how can it be prevented

19
Q

Know what starts the analytical phase of accident investigation

A

Once the accident sequence is determined the analytical techniques are used to determine the causal factors and corrective actions

20
Q

Know what is problem with using the root cause concept

A

One problem with using the root cause concept is that the term “root cause” has many meanings among safety professionals.
conflicting definitions:these various definitions reduce the effectiveness of the term “root cause”

21
Q

Main focus of an accident investigation

A

Fixing a problem or problems is the main focus of accident investigation.

22
Q

Four components of an accident investigation program - 4 components

A

1formal written accident investigation policy
2 training in emergency response
3 training in accident investigation
4 an accident investigation kit

23
Q
  1. What 2 actions emergency response personnel should take first
A
  1. SECURE THE SCENE -

2. PROVIDE CARE TO THE INJURED

24
Q

10 items that should be included in an accident investigation kit

A 
tools
personal protective equipment
cameras
tape measures
gloves
lights
security tape
tweezers
evidence bags

*** chart p 46
INVESTIGATIVE TOOLS ADMINISTRATIVE/RECORDING TOOLS
barricade tape camera
cones graph paper
tape measure witness statement forms
flashlights/spotlights notepad and clipboard
evidence tags analytical technique forms
evidence bags copy of the accident investigation policy
tweezers
gloves (latex & work)
PPE
binoculars

25
Q
  1. Name 4 types of evidence
A

Physical Evidence
Paper Evidence
People Evidence
Photographic Evidence

Physical Evidence - Hardware and solid material related to the accident
Paper Evidence - Any type of written documentation related to the accident
People Evidence - The evidence that is gathered from people, usually in the form of statements or interviews
Photographic or picture evidence - media that can document the scene and transfer knowledge

26
Q
  1. Know which type of evidence is least likely to be damaged in an accident
A

“Paper evidence is the least likely of the “four P’s” to be damaged or contaminated”

27
Q
  1. Know when witnesses should be interviewed
A

witnesses should be interviewed as soon as possible after the accident, but for the injured individual medical care should take precedence over interviews

28
Q
  1. Know how long you should collect evidence
A

In most accident investigations evidence collection continues until the accident sequence is determined.

Evidence collection should continue until you have enough information to document the accident sequence, determine causal factors and develop corrective actions.

29
Q
  1. 3 categories that physical evidence is broken into
A

visual
testing
placement or puzzle evidence

  • visual evidence includes information that can be gathered by looking at the scene
  • testing evidence must be analyzed in a laboratory
  • placement or puzzle evidence that has broken into pieces(exploded) and must be reassembled to determine how accident occurred
30
Q
  1. Factors are important when taking photos of accident evidence
A

*take pictures as soon as possible
include a reference guide ie ruler
*keep a picture log -
coordinate angles and directions in picture log
start taking pictures at a distance
*take pictures of smoke (black petroleum, white organics)
*take enough photographs so that a person who has not seen accident site can understand accident sequence

p 54
a few good photographs are better than many ad photographs

take photos of scene before ou move anything
better - videotape are before, during and after moving an object
photograph anything that will be removed or will disappear eventually
p55
photo tips
*take big picture photos - shows environment/relationships/distances between people and equipment
*include a reference object in picture if purpose is to show relationships ie ruler or person
*keep a photo log to ID pictures and note their purpose (photo#,object or purpose of photo, location picture was taken from, direction of the shot and time picture was taken
*get up high if possible

31
Q

What analytical process is ?

A

“An accident investigation is the process of breaking down information into pieces until the investigator understands what happened; then he or she can analyze the pieces to determine ways to prevent the accident from recurring.
definition of analytical p describes the systematic thought process of breaking down information

32
Q

What is goal of causal analysis?

A

to find all of the causes including the systemic causes - not just the immediate or superficial causes.

33
Q

5 why technique is?

A

ASKING “WHY” five times to get to the root of a problem.

34
Q

What type of causal factors exist at the

worker or equipment level

A 
EQUIPMENT FAILURES
 INADEQUATE TRAINING
 INEXPERIENCE
 HUMAN ERROR
work performed, equipment operates
35
Q

What type of causal factors exist at the

supervisor level -

A 
INADEQUATE HANDLING OF:
  *JOB SAFETY ANALYSES
  *COMMUNICATION
   *SCHEDULING
 LACK OF PROPER SUPERVISION
supervisor level - describe how work is to be done
36
Q

What type of causal factors exist at the

management level -

A

BUDGET ISSUES
COMMUNICATION
POLICIES/PROCEDURES
management level - dictates policies and procedure

37
Q

What type of causal factors exist at the

corporate level -

A

PROBLEMS FOUND & CORRECTED AT THIS LEVEL PREVENTS ACCIDENTS

corporate level - dictates culture, philosophy and style of company

38
Q

Know what hazard is -

A

HAZARD - A hazard is something that has the potential to cause injury, and hazards are correctable.

39
Q

Know what failure is

A

FAILURE - A failure is something that goes wrong with personnel, equipment, or the environment.

A failure may or may not have the potential to cause injury (if it does it is also considered a hazard).

Failures are usually caused by faulty design, a defect, inadequate maintenance, limits that were exceeded or environmental effects.
