Safety Hazard Assessment <br /> As part of the accident investigation, incident investigation, or hazard identification process, an <br /> assessment will be conducted to determine the level of potential threat or hazard requiring immediate, <br /> delayed, or monitoring response. Each event assessment will include a determination of the likelihood <br /> of the event being repeated. If there is a potential for repeated safety events or hazards, the City and its <br /> contractor will review the related areas of the system for potential opportunities to reduce risk through <br /> modifications. <br /> In some cases, it may be as simple as modifications in training, but in other cases, it may extend to <br /> policies, procedures, processes,or personnel.The following tables indicate how the agency can assign <br /> values and measure risk to ascertain the severity and probability of operational hazards. <br /> Table 1.
