Change analysis is most useful when?
It is most useful for accidents that happen while routine tasks are being performed.
How can change analysis be used?
Change analysis can be used reactively or proactively.
The three types of accident free situations that can be used in change analysis are?
The same procedure as it is usually performed
A description of the job as it is supposed to be performed
A description of the job as it should be performed
What is the most important purpose of a safety program?
The most important purpose of a safety program is to identify hazards and establish barriers that will keep hazards from coming in contact with workers.
Which barrier analysis is used for preventative analysis.
Energy Trace & Barrier Analysis (ETBA)
Barrier & Control Analysis (BCA)
The three categories of barriers are?
Barriers that failed.
Barriers that were not used.
Barriers that did not exist.
What are considered hard barriers?
Hard barriers are engineered. Machine guards, PPE ect.
What are considered soft barriers?
Soft barriers are Administrative. Policies, procedures ect.
Engineered barriers that failed are usually what?
Usually design problems that can be corrected by engineers or the maintenance department.
Administrative barriers that fail must be corrected by whom?
Management
The two basic types of trees used in accident investigation are?
Fault trees
Analytic trees
Which of the two trees are used for trouble shooting?
Fault trees
Know when an “and gate” and an “or gate” are to be used.
And= Output fault occurs if all the input faults occur.
Or= Output fault occurs if atleast one of the input faults occurs
What is the best known analytical tree technique?
(MORT) Management Oversight & Risk Tree
Which of the two types of trees is more pro-active
Analytical Trees
Cause and Effect analysis is best performed “HOW”
As a chart similar to the events and causal factors analysis or tree analysis.
The three approaches to cause and effect analysis are?
Apollo Cause and Effect
Ishikawa Fishbone
5 Whys
Of the three analysis, which is software based?
The Apollo Method
What is one of the main problems with cause and effect analysis.
Stopping to soon.
Which technique is used to analyze emergency response actions?
Time Loss Analysis
What is “Human Factor” analysis?
To identify Human/Machine/Environmental interaction and to determine whether the interaction had an effect on the accident.
What is “Failure Mode” and “Effects Analysis”?
They are proactive safety tools used to help safety professionals analyze how failures can effect systems
What is design criteria analysis?
This is one component of change analysis. One tries to discover the ideal way to perform a task. During design criteria analysis, the investigator identifies the codes, design requirements, procedures and policies that should be followed when performing a task and describes how to comply with all of these standards.
The three step process in implementing corrective actions is?
Develop the Corrective Actions
Track the Corrective Actions
Follow up
