Probability of occurrence: potential security risks occur, it is extremely unlikely, impossible, possible, very likely, most likely a total of 5 levels. Risk index: the potential risk level of the abscissa and the probability of occurrence of the ordinate The cross point is the risk index. Risk risk is higher than 6 (yellow and red areas), risk control is required and risk reassessment is required. 4 can take the risk reduction method Table 2 for the stage show the potential risks and reduce the risk of the method.Table 2 Potential risks and risk reduction methods for stage performance 5 Risk reassessment risk reassessment method (see Table 3) Note:Table 3 UK Royal Opera House stage performance risk reassessment method in the use of methods to control the risk, the risk of another assessment.
