What You'll Learn
Reactive and proactive methods
Hazard identification is the process of identifying conditions, events, or circumstances that could induce an accident or contribute to one. In the context of airports, hazards can be tangible or intangible, with the former being easier to manage as they are physically visible, such as infectious diseases. Effective hazard identification in airports involves employing both reactive and proactive methods to ensure safety.
Reactive Methods
Reactive hazard identification methods involve recognizing hazards through trend monitoring and investigating safety occurrences. Incidents and accidents are clear indicators of system deficiencies, and subsequent investigations aim to identify the hazards that contributed to the event. Reactive methods are a form of simple risk management, where the response to an event occurs after it has transpired. While reactive approaches are essential for addressing unforeseen issues, they should not be the primary strategy for hazard identification.
Proactive Methods
Proactive hazard identification methods are extensively utilized in successful safety management systems. This approach involves analyzing a system's performance and functions to identify intrinsic threats and potential failures. Common proactive methods include safety surveys, operational safety audits, safety monitoring, and safety assessments. These tools help identify hazards before they lead to accidents, reducing the risk of harm to individuals, assets, and the environment.
The prognostic or predictive approach within proactive hazard identification aims to anticipate future hazards that may arise due to changes within or outside the aviation system. By identifying these potential hazards, mitigating actions can be implemented to eliminate, avoid, or reduce their impact. Proactive methods also include re-engineering processes and adjusting schedules to minimize the occurrence and severity of interactions with hazards.
Historic Approach
The Historic approach, advocated by the Future Aviation Safety Team (FAST), is based on investigating and analyzing past accidents and incidents. This approach employs proven investigative techniques to uncover opportunities for improvement and prevent similar accidents in the future.
Diagnostic Approach
The Diagnostic approach focuses on identifying accident precursors within the vast collection of information in aviation safety reporting systems. It aims to pinpoint specific factors that contribute to accidents within the larger context of aviation safety data.

Safety assessment processes
Hazard identification is a crucial aspect of ensuring safety in the aviation industry, including at airports. Safety assessment processes are comprehensive and involve multiple stages, methodologies, and stakeholders. Here is an overview of the key components of safety assessment processes in the context of hazard identification in airports:
Reactive, Proactive, and Predictive Approaches
Data Collection and Analysis
Data plays a vital role in safety assessments. Airports collect data through various sources, including mandatory and voluntary safety occurrence reporting schemes, automated data collection tools like flight data analysis (FDA), safety surveys, operational oversight safety audits, monitoring of normal operations and the environment, investigation results from accidents and incidents, and information exchange between operators and service providers. Analyzing this data helps identify patterns, trends, and potential hazards, enabling risk assessment and informed decision-making.
Hazard Identification Techniques
Common hazard identification techniques used by airports include brainstorming sessions, safety checklists, safety performance indicators (SPI), incident and inspection reports, structured What-if (SWIFT) analysis, and safety audits. Brainstorming sessions, led by facilitators, involve using tools like the 5M Model to describe the system and identify hazards. Checklists and safety performance indicators provide structured guidance to ensure comprehensive hazard identification across various airport operations. Incident and inspection reports document past occurrences, contributing to a historical understanding of hazards. SWIFT analysis involves exploring hypothetical scenarios to identify potential hazards. Safety audits provide an independent review of airport operations to identify risks and ensure compliance with safety regulations.
Safety Management Systems (SMS) and Reporting
Aviation service providers and airports utilize Safety Management Systems (SMS) to identify, assess, and manage hazards. Effective SMS implementation requires a formal hazard reporting system that is accessible and regularly used by employees at all levels. This includes user-friendly reporting tools, safety training, and documented procedures. Reported hazards are then acted upon in a timely manner, with corrective measures implemented to restore normal operations and reduce the likelihood of similar incidents in the future.

Diagnostic, prognostic, and predictive approaches
Hazard identification is a critical aspect of aviation safety, and it involves a range of approaches to ensure that potential dangers are recognised and addressed. Diagnostic, prognostic, and predictive strategies are essential components of hazard identification, each serving a distinct purpose in enhancing airport safety.
The "Diagnostic" approach is a crucial element of hazard identification, focusing on the analysis of extensive aviation safety reporting systems to identify accident precursors. This method involves scrutinising large datasets from various sources, including mandatory and voluntary safety occurrence reporting schemes, internal investigations, safety occurrence trend analysis, personnel feedback, flight data analysis, safety surveys, operational oversight safety audits, day-to-day operations monitoring, official accident investigations, and information exchange between operators. By examining these diverse sources of information, the diagnostic approach aims to identify patterns, trends, and indicators that may foreshadow accidents or incidents. This proactive strategy enables safety managers to address potential hazards before they escalate into full-blown accidents.
Prognostic and predictive approaches are closely linked and play a pivotal role in anticipating future hazards within the aviation industry. These forward-looking strategies aim to identify potential dangers that may arise due to changes within or outside the global aviation system. By adopting these approaches, safety professionals can proactively initiate mitigating actions to eliminate, avoid, or reduce the impact of future hazards. Prognostic hazard identification is particularly valuable in informing design processes, ensuring that future aircraft designs can mitigate or avoid identified risks. For instance, in 2021, the European Aviation Safety Agency (EASA) published an opinion on Operational Suitability Data, addressing the link between certification and operation, which helps inform prognostic hazard identification.
The prognostic approach is closely associated with Prognostics and Health Management (PHM) in aviation. PHM involves the proactive surveillance and evaluation of critical subsystems within aircraft systems. By utilising predictive modelling techniques and real-time data analysis, PHM aims to predict the remaining useful life of subsystems and proactively mitigate potential breakdowns. This predictive maintenance (PM) approach leverages real-time data to forecast machinery health and potential failures, triggering maintenance operations before malfunctions occur. PHM is essential for maintaining aircraft safety and dependability, minimising the consequences of breakdowns, and ensuring the integrity of aviation systems.
Additionally, the reactive and proactive methods of hazard identification also play a significant role in airport safety. Reactive hazard identification involves recognising hazards through trend monitoring and investigating safety occurrences, such as accidents and incidents. In contrast, proactive hazard identification focuses on analysing intrinsic threats and potential failures within systems, performance, and functions. Safety surveys, operational safety audits, safety monitoring, and safety assessments are commonly employed proactive methods. By utilising these complementary approaches, airports can effectively identify and address hazards, ensuring a safer environment for employees, passengers, and aircraft.

Safety reporting systems
Hazard identification is a crucial process in aviation safety, and various methods and systems are employed to identify, assess, and mitigate hazards that may impact the safety of airport operations. Safety reporting systems play a vital role in this process by facilitating the collection, analysis, and dissemination of safety-related data and information. These systems enable airports to maintain safe operations and comply with regulatory requirements.
The Transportation Research Board's (TRB) Airport Cooperative Research Program (ACRP) Synthesis 58 provides valuable insights into safety reporting methods and systems for airports. It assesses current practices, processes, and systems used to gather and analyse safety data, specifically focusing on airports certificated under Title 14 Code of Federal Regulations Part 139.
Additionally, safety reporting systems in airports may include safety occurrence reporting through mandatory and voluntary schemes, analysed data from automated data collection tools (e.g., flight data analysis), safety surveys, and operational oversight safety audits. Monitoring day-to-day operations, investigating accidents and incidents, and information exchange between operators and service providers are also integral components of these systems.
To effectively utilise safety reporting systems, airports employ reactive and proactive approaches to hazard identification. The proactive approach is extensively used in successful safety management systems, aiming to recognise and address hazards before they lead to occurrences. This proactive strategy complements the "Historic" approach, which involves investigating and analysing past incidents to identify opportunities for improvement and prevent similar future accidents. Furthermore, the "Diagnostic" approach identifies accident precursors within aviation safety reporting systems, while the "Prognostic" or "Predictive" approach focuses on anticipating future hazards and initiating mitigating actions.

On the other hand, the reactive approach includes incident investigation and safety occurrence reporting, allowing for a better understanding of risks after they have occurred.
Safety Assessment and Risk Classification
Safety assessments are vital for identifying, classifying, and assessing hazards. This process should be integrated into the design and certification stages to establish clear links with operations. Safety assessments can include mandatory and voluntary safety occurrence reporting, flight data analysis, safety surveys, operational oversight safety audits, monitoring of normal operations, investigation results from accidents and incidents, and information exchange between operators and service providers.
Risk Mitigation and Control Measures
Once hazards have been identified and assessed, risk mitigation strategies should be implemented. If the risk is unacceptable, control measures are employed to fortify defenses, avoid the risk, or remove it if economically feasible. These control measures, also known as risk controls, aim to reduce the potential impact or damage that a hazard may cause.
Predictive and Monitoring Techniques
With the increasing complexity of flight operations, a proactive, systematic, and structured approach to risk assessment is necessary. Predictive techniques help identify future hazards that may arise due to changes within or outside the aviation system, allowing for proactive mitigation.
