Q

What is the accident/ incident theory?

A

Extension of human factors
Overload of ergonomic traps leads to human error

19
Q

What is systems failure?

A

Demonstrates casual relationship between management decisions, behaviour and safety

20
Q

How can a system fail?

A

Workers not trained properly
Safety responsibility not defined
Safety procedures ignored

21
Q

What is the epidemiological theory?

A

Study of relationships between environmental factors and accidents/disease
Key components: predispositional characteristics and situational characteristics

22
Q

What are the event chain theories?

A

Domino, accident/incident, epidemiological, human factors

23
Q

What are the similarities between each event chain theories?

A

Occur in sequence
Ignores indirect relationships
Involve human error, component failure, and energy relate factors

24
Q

What are the limitations to event chain theories?

A

Neglect social and organizational factors
Not consider external factors with respect to human error
Ignores tendency of experienced workers to behave at a higher risk

25
Q

What is a system?

A

Group of regulatory interacting interrelated components that together form a unified whole

26
Q

What is the systems theory comprised of?

A

Person
Machine
Environment
Determined by the three components

27
Q

What are the three activities that take place between system and the task to be performed?

A

Collect information
Weight risks
Make a decision 

28
Q

What is the combination theory?

A

Explains the cause of an accident by combining parts of several different models

29
Q

What is behavioural theory?

A

Rooted in psychology
Known as behaviour based safety

30
Q

What are the seven key principles for behavioural theory?

A
  1. Intervention focus on employee behavior.
  2. Identify external factors to understand and improve employee behavior.
  3. Direct with activators(events) and motivate with incentives (rewards)
  4. Focus on positive consequences to motivate behavior.
  5. Apply scientific method to improve intervention.
  6. Use theory to integrate information.
  7. Design interventions with feelings and attitudes of affected individuals in mind. 
31
Q

What do we look at an accident investigations?

A

Investigate critical injuries, as well as lost time incidents
Incidents not resulting in injury or property damage is still investigated.
Fact-finding mission not fault finding mission

32
Q

What happens in the workplace when accident reporting happens?

A

When injured, employer must notify the MLITSD joint health and safety committee within 48 hours

  1. Provide first aid and medical care to injured person
  2. Report the accident to a designated person within organization
  3. Investigate the accident
  4. Identify the causes.
  5. Report the findings.
  6. Develop a plan for corrective action

  9. Make changes for continuous improvement.
34
Q

A

Personal beliefs and feelings, example, invincible
Decision to work on safely
Mismatch or overload —> fatigue, stressed
System failure —> insufficient training, inadequate tools
Traps —> poor design of workstation and processes
Unsafe conditions
Unsafe acts —> unauthorized tools, or equipment use

39
Q

What is the fifth step of accident investigation?

A

Report the findings of cause
Report recommendations for corrective action

40
Q

What is the six step of accident investigation?

A

Develop a plan for corrective action
Consider all recommendations
Identify which recommendations will be implemented
Develop implementation plan —> timeline for implementation

41
Q

What is the seventh step of accident investigation plan?

A

Implement the plan

42
Q

What is the eighth step for accident investigation?

A

Evaluate the effectiveness of the corrective action
Qualitative, and or quantitative —> look at number of people participating in training
Ensure no new hazards, risk arise from this new corrective action

43
Q

What is the ninth and last step for accident investigation?

A

Make changes for continuous improvement
Still work on a safe environment

44
Q

What are some mistakes for accident investigation?

A

Not investigating near misses
Taking ineffective, corrective action —> can still remain if it’s ineffective
