Understanding Risk
几乎所有事都会有一定程度的相关风险,比如: Almost everything we do has some degree of risk associated with it, for example :
“风险评估的关键就是对所进行的工作进行仔细的检查,找出那些可能导 致人员伤害的原因,从而衡量所采取的预防措施是否足够还是应该加强预 防力度”。
An assessment of risk is nothing more than a careful examination of what, in your work, could cause harm to people so that you can weigh up whether you have taken enough precautions or should do more”

Definition of Hazard 风险的定义
A hazard is a property or characteristic, of a process facility, piece of equipment, commodity or activity, that has the potential of causing harm. 风险指的是加工工具,物品或活动的一 种性质或特征,有潜在引起伤害的可能 性.
我们必须对风险的重要性有着清楚的认识并尽量认知并掌握它们。 We need to have an idea of the importance of risks and to know as much about them as we can. 因此:So 我们可以就控制措施做出正确而经济有效的决定。 We can make decisions on controls which are both appropriate and cost effective.
