Safety Risk Management 69 Some of these processes can be used in combination. For example, a change analysis due to construction may use a "construction safety checklist" to evaluate potential hazards dur- ing construction. Improvised processes for hazard identification are unacceptable safety management practices. For example, simply telling airport staff to identify hazards will not work unless proper training is provided on how to identify and report hazards. Recording Hazards All identified hazards should be assigned a hazard number and be recorded in a hazard log. The log should contain a description of each hazard, its consequences, the assessed risk in terms of likelihood and severity, and any required mitigation measures. It should be updated as new hazards are identified and proposals for mitigation are introduced. Table 7 provides suggested information to include in a hazard log. Common Airport Hazards Table 8 presents several hazard categories present at airports. Each category is further broken down into specific components of the category. The third column provides some general conse- quences associated with the specific hazard category and its components. The list is not intended to be exhaustive, but to provide some helpful information that can be used to identify additional categories, components, and potential consequences. 5.4 Determine Risk One of the best methods to identify risk associated to a hazard is a brainstorming session. Per- sonnel involved in day-to-day operations are generally very familiar with "what can go wrong" situations. Another method is through lessons learned that are usually shared through industry publications and conferences or workshops. An airport operator might have identified the storage of unsecured containers as a hazard on the cargo ramp. Risk associated with this hazard is a gust of wind or aircraft jet blast setting an empty container in motion and striking a passing aircraft or person. Table 7. Hazard log table.
