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. 风险评估的正确顺序是？

The correct assessment order is:

A. 先可能性后严重度 Likelihood before severity B. 先估严重度，再估可能性 Severity first, then likelihood C. 先选措施再定级 Pick controls before rating D. 先看历史事故数 Look at incident counts first

2. 「最有效」类题目中，PPE 选项的正确处理方式是？

In 'most effective' items, how should a PPE option be treated?

A. 只要题干提到有防护需求就选它 Pick it whenever the stem mentions any protection need B. 默认是干扰项，除非题目问的就是「最后防线」 Default to decoy unless the item asks for the last line of defense C. 永远正确 Always correct D. 与工程控制等价 Equivalent to engineering controls

3. 固有风险评估时，哪些措施不给记分？

Which controls earn no credit in the inherent rating?

A. 全部现有控制都不记分 No existing controls earn credit B. 只不给 PPE 记分 Only PPE earns no credit C. 工程控制照常记分 Engineering controls earn credit as usual D. 管理控制照常记分 Administrative controls earn credit as usual

4. ALARP 的正确理解是？

ALARP correctly understood is:

A. 把风险降到零 Reduce the risk to zero B. 降到再投入与收益明显不成比例为止，剩余风险知情接受 Reduce until further spending is grossly disproportionate, with informed acceptance of the residue C. 降到监管检查能通过 Reduce until a regulator passes the audit D. 降到同行业平均水平 Reduce to the industry average

5. 控制措施写「已制定操作规程」，矩阵中可能性计算的正确处理是？

A control reads 'procedure issued'. How is it credited in the matrix?

A. 按已生效控制计 Credit it as effective B. 验证被执行后才可计，否则视为未实施 Credit only after verification shows it is followed; otherwise treat as not implemented C. 按 50% 折算 Discount it at 50% D. 只影响严重度 It only affects severity

错因归类 | Sort your misses

字母依赖：记住「B 是对的」而不认措施 → 重做时先给每项措施贴层级标签Letter dependence: memorizing "B is correct" instead of recognizing controls → when redoing, first tag each control with its hierarchy level
一次评估：把固有和剩余混成一次打分 → 每题先问「这次给控制记分了吗」One assessment: scoring inherent and residual risk in a single pass → for each question, first ask "was control credited this time?"
概率淡化：用「很久没出事」压严重度 → 严重度只看能量与暴露部位Downplaying probability: using "no incident for ages" to lower severity → severity depends only on energy and the body part exposed

接下来学什么：备考基线还剩两块：Day 22–26 讲人的因素与安全文化（为什么「注意点」不管用、文化怎么测量），Day 27–31 讲公式表与备考系统。之后 Day 32–36 做基线综合自测，就正式进入 Domain 1。
Two baseline blocks remain: Day 22–26 human factors and safety culture (why 'be careful' fails, how culture is measured) and Day 27–31 the formula sheet and study system, then Day 32–36 consolidation before Domain 1.
