底格里斯－幼发拉底河谷有一个称为ASIPU的 风险分析咨询小组
Greeks & Romans
Observe causal relationship between exposure and disease
发现接触水平与疾病的因果联系
Ancient Mesopotamians
Invent insurance as a strategy for dealing with risks
• JSA Job Safety Analysis 工作安全评定 • WRAC workplace risk assessment and control
工作场所风险评估与控制 • QRA - Quantitative Risk Assessment 风险定量评定 • What If 可能性分析 • HAZOP - Hazard & Operability Study
A source of danger 危险的来源
RISK 风险
The expected loss from a hazard considering both the probability of occurrence and the magnitude of the consequence 考虑危害发生的可能性和后果严重性，进而可以预 见的损失程度。
• Exposure Ranking (ER) 接触分级 Potential exposure based on air monitoring and/or the contaminant release potential and control measures employed 根据空气监测，和/或污染物逸散潜能及采取的控制措施
风险评估概要
• Exposure Groups 接触组 Based on Process / Job / Task / Agent 根据工艺/工种/任务/危害物
• Hazard Ranking (HR) 危害分级 Based on the potential effects of overexposure 根据过量暴露可能产生的不良效应
(c) The agent - when a hazardous chemical or physical agent is common to an entire group 根据危害物，当某种有害化学物或物理因素对整个组工 人普遍产生危害时。
Summary of Risk Assessment Process
发明保险作为防范风险的方法
1950 B.C. (Babylonia) 400 B.C. (Hypocrites)
Code of Hamurabi formalizes contracts containing risk premium contracts for the chance of loss of ships 汉谟拉比法典阐述了含有海难风险的合同条 款
PROBABILITY AND CONSEQUENCE RATING SYSTEM
可能性与严重性分级系统
PROBABILITY 可能性 X CONSEQUENCE 严重性 = RISK 风险
INDUSTRIAL HYGIENE RISK ASSESSMENT 工业卫生风险评估
A SEMI-QUANTITATIVE APPROACH 半定量方法
(a) The process, if all employees in group have si果组内所有工人接触程度相似
(b) The job or task - when employees are assigned to specific jobs / tasks, or 根据工种或任务，在工人被安排从事明确的工作时
Correlation between exposure and disease 接触水平与疾病的关系
RISK ASSESSMENT TECHNIQUES 风险评估技术
• Qualitative 定性分析 • Semi-Quantitative 半定量分析 • Quantitative 定量分析
RISK ASSESSMENT TECHNIQUES 风险评估技术
Main Steps 主要步骤
1. Select the Assessor 选择评估人 2. Gather information on chemicals, work & work practices
危害与可操作度研究 • FMEA - Failure Mode Effect Analysis
失败模式和效应分析 • Fault Tree/ Event Tree 故障/事件树型分析 • Human Reliability Analysis 人员可靠性分析 • Checklists 检查表
HAZARD 危害
In the IH context, 在工业卫生领域
Hazard Potential 危害潜能 X Exposure Potential 暴露程度 =
RISK 风险
Exposure Groups 接触组
Define exposure groups based on either : 根据如下情况确定接触组：
• Frequency - Typical duration of exposure 接触频率－典型的接触时间
• Risk Rating (RR) – Based on degree of exposure and severity of consequence 风险分级－根据接触程度和效应的严重性
