If a risk is assessed and falls within one of the red <br /> zones,the risk is determined to be unacceptable under existing circumstances.This determination <br /> means that management must take action to mitigate the situation.This is the point in the process <br /> when transit SRMs are developed. If the risk is assessed and falls within one of the yellow zones,the risk <br /> is determined to be acceptable, but monitoring is necessary. If the risk falls within one of the green <br /> zones,the risk is acceptable under the existing circumstances. <br /> Once a hazard's likelihood and severity have been assessed,the CSO, in consultation with the service <br /> provider,enters the hazard assessment into the Risk Register that is used to document the individual <br /> hazard and the type of risk it represents.This information is used to move to the next step,which is <br /> hazard mitigation. <br /> HA, Saffety Risk Mifigation — 673,25(d) <br /> Upon completion of the risk assessment,the CSO, in consultation with the service provider,continues <br /> populating the Risk Register by identifying mitigations or strategies necessary to reduce the likelihood <br /> and/or severity of the consequences.The goal of this step is to avoid or eliminate the hazard or,when <br /> elimination is not likely or feasible,to reduce the assessed risk rating to an acceptable level (Figure 7). <br /> However, mitigations do not typically eliminate the risk entirely. <br />
