Which one of the following types of risk analysis uses historical data to assign specific values to
consequences and their probabilities to reach a numeric indication of the level of risk? -
ANSWER Quantitative analysis
From a system safety perspective, change analysis is an analysis - ANSWER That projects the
effects a given system change is likely to have on an existing system
A worker for Build-Rite Construction Company removed the pressure gauge and warning sticker
from an air compressor. The pressure gauge automatically shuts off the compressor when the
pressure gets too high. The sticker warned that an explosion could result if the pressure was too
high. Without the pressure gauge in place, the air compressor exploded. The explosion killed
one worker and severely injured another. If Build-Rite performs a root cause analysis (RCA) of
this fatal accident, which one of the following might be determined to be a root cause? -
ANSWER Inadequate training
Using fault tree analysis, an "and" gate is connecting the events in rectangles C, D, and E to the
event in rectangle A. If the probabilities of events in rectangles C, D, and E of the fault tree are
.10, .20, and .30, respectively, what is the probability that the event in rectangle A will occur? -
ANSWER .006 ----- (p(C) X p(D) X p(E); .10 X .20 X .30 = .006
A phase in the life of a system when the basic purpose and preliminary design of the system are
formulated is the - ANSWER Conceptual phase
Within a system safety context, the engineering phase of a system's life cycle is that phase in
which - ANSWER The system's design is constructed and prototypes are tested.
,One form of root cause analysis utilizes a fishbone diagram. Under this technique, a team of
investigators brainstorms the causes of a risk event, sorts them into categories, and traces them
to their origin. This type of analysis relies heavily on a - ANSWER "5 Whys" analysis.
The second step in the root cause analysis (RCA) process is charting the agents that directly
result in one event triggering another event. In RCA, these agents are called - ANSWER Causal
factors
Harris Company is analyzing its workers compensation loss exposure. Harris Company retains
most of the exposure and purchases excess insurance to cap its liability on any individual claim.
Because Harris Company has a large work force, it can predict its workers compensation cost
with some level of accuracy. For next year, the risk manager estimates that there is a 70%
chance that workers compensation costs will be $6 million or less, a 25% chance workers
compensation costs will be between $6 million and $8 million, and a 5% chance workers
compensation costs will exceed $8 million. The type of analysis the risk manager performed is
called - ANSWER Quantitative analysis
Vicki has been hired to investigate industrial accidents for a biotech company that produces a
number of drugs. In most cases, she will be asked to look at a particular system failure and trace
the events leading to the failure backwards. Which system safety analysis technique would be
most appropriate for this application? - ANSWER Fault tree analysis
An approach to accident causation, which looks at an organization as a whole to identify
potential sources of losses is - ANSWER System safety analysis
Air-Freight Company wants to use failure mode and effects analysis (FMEA) to analyze its
systems, subsystems, components, sub-assemblies, and parts. Level 1 is the overall system for
shipping freight. Level 2 is the system segments, with the prime items (air freight hubs,
schedulers, and logistics) designated as Level 3. Level 4 is the subsystems (local freight handlers,
package sorters, etc.). Level 5 is the hardware and parts (forklifts, conveyor belts, planes, and
delivery vans, etc.). In FMEA, these various systems and subsystems are called - ANSWER
Indenture levels
, After a metal pressing machine crushed an employee's arm, the risk manager of Metal Fab
Company called a meeting. Those present at the meeting included the company's safety
manager, the plant foreman, the part-time mechanic in charge of maintenance of the machine,
the co-worker who taught the injured worker to use the machine, and the plant manager who
purchased the machine two years ago. After completely describing the injury, the risk manager
led a discussion on what caused the injury. Each time the group agreed on a cause, the risk
manager asked what the reason for the cause was. After several rounds of this process, it was
determined that the machine crushed the employee's arm because of failure to perform regular
maintenance on the machine due to under-staffing. The type of root cause analysis conducted
by the risk manager is called - ANSWER 5 Whys
Tom works as a safety engineer at Cold Rolled Steep Corporation. During a system safety
analysis, he identified the important components of the production process and has ranked the
severity of losing each component into four failure categories. This is an attempt to establish
priorities of the hazards and controls. Which one of the following analyses is Tom using? -
ANSWER Criticality analysis
An organization has had a high percentage of repetitive stress injuries to workers in a particular
phase of their production process. The risk manager has been asked to analyze these injuries
from a system safety analysis perspective. Which one of the following techniques should the risk
manager use to investigate these accidents? - ANSWER Job safety analysis
The purpose of fault tree analysis is to - ANSWER Identify the various ways of interrupting the
sequence of events leading to system failure so that the failure itself can be prevented.
Risk manager Christine is analyzing the risks faced by her company, Clear Sky Technology. She
assigns a rating based on the significance of the consequences of the various risks. Her four
ratings are: Low, Medium-Low, Medium-High, and High. The ratings that Christine assigns are a -
ANSWER Qualitative assessment.
Which one of the following statements about root cause analysis (RCA) is true? - ANSWER A
root cause must produce effective recommendations for prevention of future accidents
