五题复盘 | Five-question recap

选出答案并提交，查看解析与依据。/ Pick an answer, submit, and read the rationale.

1. 职业暴露控制四步的正确顺序是？

The correct order of the four exposure-control steps is?

A. 评价 → 识别 → 预期 → 控制 Evaluate, recognise, anticipate, control B. 预期 → 识别 → 评价 → 控制 Anticipate, recognise, evaluate, control C. 控制 → 评价 → 识别 → 预期 Control, evaluate, recognise, anticipate D. 识别 → 控制 → 预期 → 评价 Recognise, control, anticipate, evaluate

2. 暴露比值 1.2 意味着什么？

What does an exposure ratio of 1.2 mean?

A. 暴露可接受 Exposure is acceptable B. 超过 OEL 20%，须立即控制并复测 20% above the OEL: control at once and resample C. 等于行动水平 Equal to the action level D. 采样错误 A sampling error

3. 个体采样与定点采样的关键差别是？

The key difference between personal and area sampling is?

A. 仪器品牌 Instrument brand B. 个体采样跟随呼吸带，结果才与 OEL 可比 Personal sampling follows the breathing zone, which is what makes the result comparable to an OEL C. 定点采样更准确 Area sampling is more accurate D. 个体采样更便宜 Personal sampling is cheaper

4. 轮岗作为控制措施的局限是？

What is the limitation of job rotation as a control?

A. 没有局限 No limitation B. 它把暴露摊给更多人，总剂量不减 It spreads exposure over more people without cutting the total dose C. 成本太高 It costs too much D. 只适用于夜班 It only works on night shift

5. 「法定限值」与「健康目标」分别对应？

Which pair matches 'legal limit' and 'health target'?

A. TLV / PEL B. PEL / TLV（或 REL） PEL / TLV (or REL) C. STEL / ceiling D. REL / PEL

错因归类 | Sort your misses

读数没有类型就对照 → 每个数字标注 TWA/STEL/ceiling 与采样位置Comparing readings without a type label → tag every number with TWA/STEL/ceiling and the sampling location
把合法当可接受 → 报告固定写「决策标准」与「合规标准」两条Treating legal as acceptable → the report always includes two lines: 'decision criteria' and 'compliance criteria'
跳层级直接买 PPE → 方案按消除→工程→管理→PPE 排序Skipping levels and buying PPE directly → order the plan by elimination → engineering → administrative → PPE

接下来学什么：下一块（Day 67–71）进入具体介质的第一种：噪声。噪声剂量公式（块 5 学过）在这里升级为听力保护计划的完整逻辑——从交换率到衰减值计算（NRR），从基线听力图到年度复测。
Next block (Days 67–71) takes on the first specific agent: noise. The dose formula from block 5 grows into a full hearing-conservation programme — exchange rates, NRR attenuation, baseline audiograms and annual retests.
