Airports are using tools that help them identify risks within their environment. Most airports are providing a means to report risk. Smaller airports use low-cost options such as email, a 24/7 phone number, or a suggestion box. Larger airports have embraced safety management or enterprise risk management programs that include more expensive reporting and tracking systems. The TRB Airport Cooperative Research Program's ACRP Synthesis 106: Airport Risk Identification and Prioritization Practices provides information about the existing tools that airports use for identifying common hazards and the processes used for measuring, monitoring, and prioritizing the associated risks.
