本课只做一件事：用 5 道题检验「人机工程学基础」，并把错的那几道归到具体原因上。
Test Ergonomics Fundamentals with five items and trace every miss to a specific cause.
本课不涉及：不出新知识点——只检验前四课学过的内容。
Not covered here: No new material — only what lessons 1 to 4 covered.
本课目标 | Learning objectives
- 5 题至少答对 4 题，并说清每题依据
- 把错题归为「词不懂 / 问句读错 / 依据不足」三类之一
- 说出本块学到的三条可迁移结论

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. 肌肉骨骼风险的三个叠加要素是？
The three stacking factors of musculoskeletal risk are?
2. NIOSH 方程中，条件越差，乘数会？
In the NIOSH equation, worse conditions make the multipliers?
3. LI = 2.4 属于哪个档？
Which band is an LI of 2.4 in?
4. 下列哪项属于人机工程的工程控制？
Which of these is an ergonomics engineering control?
5. 腕部反复偏转最典型的累积性损伤是？
The classic cumulative injury from repeated wrist deviation is?
错因归类 | Sort your misses
- 把培训当首选控制 → 回看层级：工程 > 管理 > PPE，培训在最弱一档Treating training as the first-choice control → revisit the hierarchy: engineering > administrative > PPE; training sits in the weakest tier
- 乘数方向记反 → 记一句「条件差 = 打折多 = RWL 小」Remembering the multiplier direction backwards → remember 'worse conditions = bigger discount = smaller RWL'
- 只治单项要素 → 检查措施是否覆盖三要素中的其余两项Treating only one element → check whether the measures cover the other two of the three elements
接下来学什么：下一块（Day 87–91）处理「别人公司的员工在你现场受伤」的问题：承包商与多雇主现场——OSHA 四角色、资格预审三项数据、入场告知与停工权。
Next block (Days 87–91) handles injuries to other companies' people on your site: contractors and multi-employer sites — OSHA's four roles, prequalification data, orientation and stop-work authority.
