Study Notes

The Tenerife Airport Disaster

The Tenerife Airport disaster on March 27, 1977, saw two Boeing 747 airplanes collide on the runway.
This incident led to 583 fatalities and remains the deadliest aviation accident in history.
The crash was caused by a combination of communication failures, misunderstandings between pilots and air traffic control, and a lack of clear procedures for handling congested runways.

Learning from the Tenerife Disaster

The disaster prompted significant changes in the aviation industry, highlighting the critical need for improved safety practices.

Crew Resource Management

The concept of Crew Resource Management (CRM) emerged following the Tenerife disaster.
CRM training focuses on improving teamwork, communication, and decision-making in the cockpit.

The Swiss-Cheese Model of Accident Causation

The Swiss-Cheese Model is used to understand how accidents occur in complex systems like aviation.
It highlights the idea that accidents happen because multiple layers of defenses, like Swiss cheese, fail to prevent an accident.
Each layer has holes representing potential failures, and when multiple holes align, an accident can occur.

Key Components of the Swiss-Cheese Model

Latent Conditions: These are underlying system flaws that may lie dormant, hidden from view.
These often result from organizational or managerial decisions such as poor safety culture or inadequate procedures.
Active Failures: These are errors or violations by front-line personnel directly contributing to an accident. These are often due to human behavior.
Defenses: These are the layers of the Swiss cheese system that prevent accidents.
- Technology: Ensuring all equipment is up to standard and designed with safety in mind.
- Training: Providing staff with the right knowledge and skills to prevent errors.
- Regulations: Strong regulatory oversight to ensure compliance and proper safety protocols are followed.

Active Failures: Errors and Violations

Errors: Unintentional mistakes made by workers trying to follow procedures but failing.
- Slips and Lapses: Unplanned actions or memory failures.
- Mistakes: Errors in planning or decision-making.
Violations: Deliberate deviations from regulations, procedures, or norms.
- Situational Violations: Committed in response to specific contexts (e.g., time pressure).
- Routine Violations: Become normalized within work groups as ways to overcome practical difficulties.

Workplace Conditions

Refer to the immediate working environment and its influence on front-line workers' efficiency and safety.
Factors like outdated procedures, language barriers, and lack of training can hinder safe operations.

Primary Interface: Liveware-Software (L-S) Interface

Addresses interactions between human operators and software systems (e.g., automated landing systems).
Software bugs, incomplete testing, and communication breakdowns can create dangerous situations.

Secondary Interface: Liveware-Liveware (L-L) Interface

Focuses on communication and coordination between personnel (e.g., pilots and air traffic control).
Lack of clear communication or understanding of procedures can increase the risk of accidents.

Safety Culture

A safety culture is the shared beliefs, values, and behaviors of an organization regarding safety.
A strong safety culture promotes open communication, encourages reporting of safety concerns, and encourages proactive hazard mitigation.

Components of a Safety Culture

Trust and Respect: Essential elements for fostering open dialogue and addressing safety issues.
Reporting and Learning: Encouraging personnel to report accidents and incidents without fear of punishment.
Commitment to Safety: Demonstrated by leadership and management through resource allocation and active participation in safety initiatives.

National Culture

Shapes the approach to safety management and regulatory oversight.
Cultural differences can influence how societies view individual responsibility, authority, and resource allocation.

Safety Culture Promotion and Assessment

Safety Culture Assessment: Valuable for evaluating the effectiveness of a safety culture.
Sector-Specific Organization Risk Profile (ORP) Assessments: Help address industry-specific safety risks.
Safety Awards and Promotional Schemes: Incentivize organizations to assess, improve, and actively promote their safety cultures.
