Study Notes
Health, Safety & Environment (CDB 1012/CЕВ 1032)
- Course is about accident causations, definitions, theories, and the price to pay.
- Module 2.1 focuses on accident causations.
Lecture Contents & Outcomes
- Understanding accidents and incidents
- The reason for learning about accident causation theories
- Learning the underlying messages in different theories, their similarities, and differences
- Understanding the cost of accidents
What is an Accident?
- An unintended or unplanned event
- Characterized by unacceptable consequences, such as injury or damage
- Any unwanted event leading to harm to people, property, or processes
- Incident is an observable human activity creating an unwanted event with a negative impact
Example of a Workplace Accident
- A carpenter's apprentice was killed by a nail fired from a power tool.
- The tool operator didn't receive proper training.
- No personal protective equipment (PPE) was worn.
Why do we need to know how accidents happen?
- To prevent future accidents
- To understand immediate causes and underlying causes of accidents
- To focus on how to prevent similar incidents
Nature Of Accidents
- The event itself that needs to be prevented to prevent consequences
- "Near misses" (no actual damage) are also relevant
- The final loss (e.g., injury, death) resulting from an accident
- Consequences may not be immediately obvious
Accident Causation Theories
- Theory is the bridge between experiment and practice.
- Good accident theories identify problems for targeted prevention efforts
- Accidents are caused, not random
- Engineering techniques can be applied to prevent accidents
- Provide a classification system to categorize and analyze accidents
- Provide a logical framework for identifying hazards
- Ensure accident investigations are based on logical reasoning
Accident Causation Theories - Examples
- Heinrich's Domino Theory: Accidents result from a series of factors that trigger injury; the sequence begins with social environment and undesirable traits, followed by unsafe acts or conditions leading to an accident, concluding with injury
- Human Error Theory: Accidents are caused by a chain of events ultimately due to human failure; interactions between people, tools, technology, environment, jobs, and organization causes mismatches that lead to either accidents or solutions to prevent them
- Accident/Incident Theory: Extends Human Factors Theory, encompassing ergonomic traps (uncomfortable workstation) and decision-making errors (misjudging risk). Also assesses the management's role in accidents
- Systems Theory: Likelihood of an accident depends on interactions between the person, the machine, and the workplace environment; aspects like the change in working schedule, noise, new machinery can affect likelihood of accident
- Combination Theory: Actual causes are combinations of several theories; safety professionals must analyze the contributing factors in accidents and not rely on a single theory (one model does not fit all)
Cost of Accident
- Accidents have direct and indirect costs (the iceberg model)
- Direct costs are easier to quantify (e.g., insurance claims, medical expenses)
- Indirect costs are harder to quantify but often significantly greater than direct costs (e.g., time lost, training costs for new workers)
Summary
- Many theories provide insight into accident situations.
- Identifying the underlying messages and similarities/differences among theories is crucial.
