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. 大气监测的正确顺序是？

The correct atmospheric testing order is?

A. 可燃 → 氧 → 有毒 Flammable, oxygen, toxics B. O₂ → 可燃 → 有毒 O₂, flammable, toxics C. 有毒 → 可燃 → O₂ Toxics, flammable, O₂ D. 任意顺序 Any order

2. 氧气的合格区间是？

The acceptable oxygen range is?

A. 16% – 25% B. 19.5% – 23.5% C. 18% – 24% D. 20.9% 以上即可 Anything at or above 20.9%

3. 可燃气体的撤出线（任何人可下令撤出）通常是？

The usual flammable gas evacuation trigger is?

A. 50% LEL B. 10% LEL C. 100% LEL D. 1% LEL

4. 动火结束后火种监护须持续多久？

How long does the fire watch remain after hot work ends?

A. 5 分钟 5 minutes B. 10 分钟 10 minutes C. 30 分钟 30 minutes D. 直到下班 Until the shift ends

5. 受限空间救援的首选方式是？

The preferred rescue method is?

A. 监护人立即下井 The attendant climbs straight in B. 非进入式救援（绞盘 + 撤离绳） Non-entry rescue (winch and retrieval line) C. 等消防到现场再决定 Wait for the fire service to decide D. 叫更多同事拉人 Call more colleagues to pull him out

错因归类 | Sort your misses

单点单次测量当结论 → 清单固定三高度、通风后复测Treating a single one-point measurement as the conclusion → the checklist fixes three heights and a retest after ventilation
把监护人当人手 → 角色不可兼任，写在许可上Counting the attendant as extra hands → the role cannot be doubled; write it on the permit
救援写「打 120」→ 非进入式装备到位才批进入Writing 'call 120' as the rescue plan → approve entry only when non-entry rescue equipment is in place

接下来学什么：下一块（Day 57–61）回到看得见的能量：吊装与物料搬运。吊索角把 4,000 kg 的箱子变成 5,600 kg 的张力，载荷表、设计系数与溜绳构成另一套「能量 × 几何」的判断。
Next block (Days 57–61) returns to visible energy: rigging and material handling. The sling angle turns a 4,000 kg box into 5,600 kg of tension; load charts, design factors and taglines form another 'energy × geometry' judgement.
