  "heading": "STEP 2: SCORING OF THE SAFETY RISK WITHIN THE ERCS MATRIX",
  "text": "The safety risk score is a two-digit value where the first digit corresponds to the alphabetic value resulting from the calculation of the severity of the occurrence (severity score A to X) and the second digit represents the numerical value from the calculation of the corresponding score of the occurrence (0 to 9).\nThe safety risk score shall be put into the ERCS matrix.\nFor each given safety risk score there is also a numerical equivalent score for aggregation and analysis purposes which is explained below under ‘Numerical equivalent score’.\nThe ERCS matrix reflects the safety risk score and the numerical associated figures of an occurrence as follows:\nIn addition to the safety risk score and to facilitate the determination of the urgency of the recommended action to be taken about the occurrence, the following three colours could be used in the ERCS matrix:\nColour\nERCS score\nMeaning\nRED\nX0, X1, X2, S0, S1, S2, M0, M1, I0\nHigh risk. Occurrences with the highest risk.\nYELLOW\nX3, X4, S3, S4, M2, M3, I1, I2, E0, E1\nElevated risk. Occurrences with intermediate risk\nGREEN\nX5 to X9, S5 to S9, M4 to M9, I3 to I9, E2 to E9.\nLow risk occurrences\nThe green area of the matrix contains lower risk values. They provide data for in-depth analysis on safety related occurrences that could, either in isolation or in conjunction with other events, increase the risk values of such occurrences.\nNumerical equivalent score\nEach ERCS score is assigned a corresponding numerical value of risk magnitude to facilitate the aggregation and numerical analysis of multiple occurrences with an ERCS score:\nERCS Score\nX9\nX8\nX7\nX6\nX5\nX4\nX3\nX2\nX1\nX0\nCorresponding numerical value\n0,001\n0,01\n0,1\n1\n10\n100\n1000\n10000\n100000\n1000000\nERCS Score\nS9\nS8\nS7\nS6\nS5\nS4\nS3\nS2\nS1\nS0\nCorresponding numerical value\n0,0005\n0,005\n0,05\n0,5\n5\n50\n500\n5000\n50000\n500000\nERCS Score\nM9\nM8\nM7\nM6\nM5\nM4\nM3\nM2\nM1\nM0\nCorresponding numerical value\n0,0001\n0,001\n0,01\n0,1\n1\n10\n100\n1000\n10000\n100000\nERCS Score\nI9\nI8\nI7\nI6\nI5\nI4\nI3\nI2\nI1\nI0\nCorresponding numerical value\n0,00001\n0,0001\n0,001\n0,01\n0,1\n1\n10\n100\n1000\n10000\nERCS Score\nE9\nE8\nE7\nE6\nE5\nE4\nE3\nE2\nE1\nE0\nCorresponding numerical value\n0,000001\n0,00001\n0,0001\n0,001\n0,01\n0,1\n1\n10\n100\n1000\nBoth column 10 and the row A in the matrix bear the value 0 as the corresponding numerical value.",
