� 什么是风险分析什么是风险分析什么是风险分析什么是风险分析((((RA)?)?)?)?
What is RA?
� 风险的背景 / Risk definition:
� 化工医药行业项目建设中,常面临采用高新技术、巨额投资、庞大人员队伍
组织以及持续时间长等特点,给项目带来大量不确定因素,即为风险。
Chemical and pharmaceutical projects are usually involved with high
technology, large investments, massive manpower organization etc., which
would bring a lot of uncertain factors to project construction and that is risk.

,以决定是否
需采取和如何采取进一步措施以降低风险。
Risk profile matrix provides a way that can clearly specify risks of the
system and their corresponding impacts within a matrix, therefore it can
be treated as a qualitative standard for risk assessment, so as to judge
whether it need to take measures to defeat risk.

� 在 A I-III、B I-II、C I和D I 区域,降低风险的措施必须是工程措施。采取这些工程
措施后的风险重新评估等级应该在粗线以下。
In areas A I-III, B I-II, C I and D I, measures to reduce these risks to acceptable
risks must be of an engineering nature. A re-evaluation of these risks with the
assigned engineering measures must reduce the risk level to below the bold line.
� 在 A IV、B III 和 C II 区域,降低风险的措施可以是管理措施。采取这些管理措施
以后的风险重新评估等级应在粗线以下。
In areas A IV, B III and C II measures to reduce these risks to acceptable risks
may be administrative in nature. A re-evaluation of these risks with the assigned
administrative measures must reduce the risk level to below the bold line.
� 等级在粗线以下的风险是可以接受的,不需要采取措施。
Hazards with risk levels below the bold line require no measures as these risks
are defined as acceptable.
