a. 无风险，滥用设备超出了正常使用
b. 无风险，在使用期间对设备假定权利

7. Uncertainty is often used in conjunction with the term risk, implying that uncertainty is risk. Uncertainty is an unknown situation, which may result from a lack of information to sufficiently quantify the probability of occurrence of an event and to determine the most likely outcome. Therefore, and uncertainty that has a potential for a major impact on a project should be:
Assigned a risk exposure index of 0.8 pending further resolution of the risk exposure
Ignored until additional information can be obtained to resolve the actual risk exposure
Studied to determine alternatives that may have a high risk index, but are fully understood
Resolved before project implementation, but must be resolved before starting that area of work
Resolved before project implementation or the project must be delayed pending a better understanding of the situation
不确定性通常被用作是风险的术语，暗示不确定就是风险. 不确定是一个不知道的情形，它可能是由于缺乏信息去对一个事件发生的可能性进行充分地量化，进而推断最可能的结果造成的. 因此，不确定在项目中潜在的主要影响应当是:
a. 对80%将来风险爆发的情形指定一个风险爆发系数
b. 被忽略直到得到额外的信息去解决暴露出的实际风险
c. 有计划的指定一个有选择的方法即可能有一个高风险指数，但是有足够的认识
d. 在项目执行前决定，但是必须在开始这部分工作前解决
e. 在项目执行前解决或推迟项目对未定状态达成一个好的谅解
8. A situation in which one of two or more risk events will follow an act, but the precise nature of these events may not be known and the probabilities of their occurring cannot be objectively assigned, is the definition of:
