严重性可以降低参考Q9 4.4:Risk reduction focuses on processes for mitigation or avoidance of quality risk when it exceeds a specified (acceptable) level (see Fig. 1). Risk reduction might include actions taken to
mitigate the severity and probability of harm。
比如说提取罐爆炸,能炸死5个人,严重性是10,那我在提取罐外面加个不锈钢保护罩,提取罐爆炸后只能炸伤5个人,严重性变成了8(我只是随便举个例子,可能现实中没有那种保护罩)
