Department/Area: [DEPARTMENT/AREA]

Review Date: [REVIEW DATE]

1. Assessment Scope

This risk assessment covers aircraft operations across flight operations, ground handling, maintenance activities, crew and passenger safety, emergency response readiness, and supporting safety management system (SMS) activities. It includes routine and non-routine tasks associated with aircraft movement, fueling, loading and unloading, servicing, inspection, maintenance, and response to operational disruptions or incidents. The assessment applies to employees, contractors, flight crew, cabin crew, maintenance personnel, ramp personnel, dispatchers, and other persons who may be exposed to aviation-related hazards within controlled operational areas. It excludes detailed engineering certification of aircraft design, airworthiness approval processes, and airport infrastructure design, except where those factors directly affect operational safety controls. It also excludes off-site activities not connected to aircraft operations unless they create a direct operational interface, such as transport of hazardous materials to the aircraft or emergency response coordination.

2. Risk Assessment Methodology

This assessment uses a structured job hazard analysis approach supported by a 5x5 risk evaluation method and the hierarchy of controls. Hazards are identified by reviewing operational tasks, exposure pathways, and credible failure scenarios across flight, ramp, maintenance, and passenger interfaces. Each hazard is rated for likelihood and severity before controls are applied, then reassessed for residual risk after controls are implemented. Control selection follows the hierarchy of controls, prioritizing elimination and engineering controls before administrative controls and PPE. PPE is treated as a supplementary control and is not used as the primary risk reduction measure where other controls are practicable.

3. Risk Matrix Reference

The following matrix is used to evaluate risk levels based on likelihood and severity:

		Likelihood
Rare	Unlikely	Possible	Likely	Almost Certain
Severity	Catastrophic	Low	Low	Low	Medium	Medium
Major	Low	Low	Medium	Medium	High
Moderate	Low	Medium	Medium	High	High
Minor	Medium	Medium	High	High	Extreme

5. General Control Measures

• Implement a formal Safety Management System (SMS) with hazard reporting, risk assessment, corrective action tracking, and management review.

Use the SMS to capture operational hazards, investigate incidents and near misses, and verify that controls remain effective across flight, ground, and maintenance functions.

• Maintain controlled access to operational areas and segregate pedestrians, vehicles, aircraft, and maintenance activities wherever practicable.

Use barriers, markings, permits, escort procedures, and access authorization to reduce exposure to moving aircraft and equipment.

• Require pre-task briefings and standardized checklists for high-risk activities.

Brief the task sequence, communication methods, stop-work triggers, emergency actions, and role assignments before work begins.

• Ensure PPE is selected through hazard assessment, fit for purpose, and used only as part of a broader control strategy.

Match PPE to the hazard, train workers in correct use and limitations, and inspect PPE regularly for damage or wear.

• Maintain good housekeeping and contamination control in work areas.

Keep walkways clear, remove spills promptly, store materials correctly, and prevent food, drink, and hazardous substances from being mixed in work areas.

6. Emergency Preparedness

• Maintain written emergency response procedures for aircraft fire, fuel spill, medical emergency, evacuation, decompression, and hazardous substance release. Procedures should define alarm methods, communication channels, evacuation routes, assembly points, and escalation thresholds for external emergency services.
• Ensure emergency equipment is readily available, serviceable, and appropriate to the hazard, including fire extinguishers, spill kits, first aid supplies, emergency lighting, and rescue equipment where required.
• Conduct regular drills for evacuation, fire response, spill containment, and rescue from elevated work areas so personnel can practice their roles under realistic conditions.
• Establish clear criteria for when an incident is incidental and can be handled by trained personnel versus when it requires full emergency response and area evacuation.
• Provide specific response plans for overwater operations, fuel fires, and aircraft incidents involving passengers or crew, including coordination with airport rescue and firefighting services and medical responders.

7. Training Requirements

• Aircraft Ramp and Ground Safety Training: Train personnel in apron awareness, aircraft movement zones, marshalling signals, vehicle exclusion areas, communication protocols, and safe interaction with ground support equipment. Training should emphasize situational awareness and positive confirmation before entering active areas.
  • Aircraft blind spots and jet blast hazards
  • Safe use of radios and hand signals
  • Vehicle speed control and pedestrian segregation
• Fueling and Flammable Liquid Safety Training: Train fueling personnel and supervisors on fuel hazards, ignition source control, bonding procedures, exclusion zones, spill response, and fire extinguisher use. Personnel must understand when fueling must stop and how to report unsafe conditions.
  • No-smoking and ignition control requirements
  • Bonding and equipment checks
  • Fuel spill recognition and response
• Maintenance Safety and Energy Isolation Training: Train maintenance staff on lockout/tagout, system isolation, safe testing, tool control, and working around pressurized, energized, or rotating components. Include verification steps and independent checks for critical tasks.
  • Isolation verification
  • Permit-to-work and task authorization
  • Tool accountability and foreign object debris prevention
• Fall Protection and Working at Height Training: Train workers who access aircraft tops, stands, ladders, or elevated platforms in fall prevention, fall arrest use, ladder safety, rescue planning, and dropped-object prevention. Training should be practical and task-specific.
  • Harness inspection and fit
  • Anchor point selection
  • Rescue and suspension trauma awareness
• Emergency Response and Human Factors Training: Train all relevant personnel in emergency procedures, evacuation roles, incident reporting, threat and error management, fatigue recognition, and communication under stress. This training supports timely and coordinated response during abnormal events.
  • Evacuation leadership and passenger guidance
  • Incident notification and escalation
  • Fatigue and decision-making awareness

8. Monitoring and Review

Review Frequency: Annually and after any significant incident, operational change, regulatory change, or introduction of new aircraft, equipment, routes, or procedures.

Monitoring Type	Frequency	Responsible Party	Description
Regular Inspection	Daily before operations and during shift changes	Ramp supervisors and shift leads	Inspect ramp conditions, vehicle routes, lighting, signage, FOD, spill hazards, and aircraft servicing areas to confirm controls remain effective and no new hazards have developed.
Preventive Maintenance Verification	Per maintenance schedule and before return to service	Maintenance supervisors and licensed technicians	Verify that aircraft systems, tools, test equipment, and safety-critical components are maintained, calibrated, and fit for use. Confirm that isolation and reinstallation steps are completed correctly.
PPE Inspection and Compliance Check	Before use and during routine supervisory checks	Supervisors and individual workers	Check PPE condition, fit, cleanliness, and correct selection for the task. Remove damaged or unsuitable PPE from service immediately.
Safety Observation and Audit	Monthly and after significant operational changes	Safety manager and department supervisors	Observe task performance, verify adherence to procedures, review near misses, and confirm that controls align with the current operating environment and risk profile.
Incident and Near-Miss Review	After every incident or near miss	SMS coordinator and relevant department manager	Investigate root causes, identify control failures, assign corrective actions, and track closure to prevent recurrence.

9. Special Circumstances

• Night operations increase the likelihood of visibility errors, fatigue, and vehicle-aircraft interface incidents. Additional lighting, enhanced supervision, and stricter communication discipline are required.
• Lone work in maintenance, remote stands, or out-of-hours operations increases response time in an emergency. Lone work should be minimized and subject to check-in procedures and escalation protocols.
• Severe weather, including lightning, high winds, ice, snow, and low visibility, can rapidly increase operational risk and may require suspension of ramp or flight activities until conditions improve.
• Irregular operations, delays, diversions, and schedule pressure can increase human error and shortcut behavior. Supervisors should reinforce stop-work authority and avoid production pressure overriding safety controls.
• Operations involving hazardous materials, overwater routes, or special cargo require additional planning, equipment, and emergency coordination because the consequences of failure are more severe.
