Q

Three types of risk in engineering systems

A
  • Were acceptable at the time of design or in the work plan
  • Risks that come from abnormal conditions

18
Q

True of false: Proactive preventative approaches to safety during design process is more cost-effective

A

True.

19
Q

Define DFS

A

Design for safety is a process that utilizes the system safety process ot intentionally design-in safety. Anticipates and eliminates

20
Q

Define SSP

A

System safety program is a formal approach to eliminate hazards through engineering, design, education, management policy, and supervisory control of conditions and practices.

21
Q

What are the three layers in evaluating a system

A

the system
your lens
the information

22
Q

What is the goal of system safety

A

The protection of life, systems, equipment, and the environment

23
Q

What is the objective of system safety?

A

elimination of hazards that can result in death, injury, system loss, and damage to the environment. If not eliminate, reduce risk of mishap through design control measures

24
Q

How is reducing mishap risk achieved?

A

reducing the probability of the mishap and/or severity of the mishap

25
Q

Alternative system safety definition

A

the application of engineering and management principles, criteria, and techniques to achieve acceptable risk within the constraints of operational effectiveness and suitability, time, and cost throughout all phases of the system life cycle

26
Q

System Safety Engineering

A

An engineering discipline that employs specialized knowledge and skills in applying scientific and engineering principles, criteria, and techniques to identify hazards and then to eliminate the hazards or reduce the associated risks when the hazards cannot be eliminated.

27
Q

System Safety Management

A

All plans and actions taken to identify hazards; assess and mitigate associated risks; and track, control, accept, and document risks encountered in the design, development, test, acquitision, use and disposal of systems, subsystems, equipment, and infrastructure

28
Q

Basic concept of system safety

A

formal process of designing-in safety by designing-out hazards or reducing the mishap risk of hazards

29
Q

Core system safety process

A

safety plan, identify hazards, assess hazard risk, identify safety measures, reduce risk, verify risk reduction, review hazards and risk, track hazards

30
Q

What does the system safety progam plan specify?

A

all of the safety tasks that will be performed, including the specific hazards analyses, reports, etc

31
Q

What are the theories of accident causation?

A 
domino
human factors
accident/incident
epidemiological
systems
combination
behavioral
32
Q

What are the 5 facorsin the eequence of events leading up to an accident in domino theory?

A
  • Ancestry and social environment
  • Fault of person
  • unsafe act/mechanical or physical hazard
  • Accident
  • Injury
33
Q

What are Heinrich’s Corrective Actions?

A
  • Engineering
  • Education
  • Enforcement
34
Q

What is epidemiological theory?

A

The study of casual relationships between environmental factors and disease.

35
Q

What are the two main factors in epidemiological theory?

A

Predisposition

Situational

36
Q

What are individual differences in epidemiological theory?

A
  • Drugs
  • Depression
  • Obesity
37
Q

What is the basis of behavioral theory?

A

ABC: activators/antecedents precede behaviours that produce the consequences

38
Q

What is systems theory?

A

Changes in the patterns of interactions can increase or reduce the probability of an accident

39
Q

What activities are systems elements designed for to support workers that allow tasks to be accomplished without accident?

A
  • Collect system information
  • Assess risks
  • Decide on tasks/actions
40
Q

What is the basis of combination theory?

A

Causes of accident are due to parts of several theories/models

41
Q

What are some insights from theories?

A
  • multiple events lead to accidents
  • some factors can directly or indirectly cause accidents
  • Social and organizational factors matter as much as human/machine/environmental
  • Workers and systems adapt/evolve over time
