本课只做一件事：用 5 道题检验「机械防护与进阶上锁挂牌」，并把错的那几道归到具体原因上。
Test Machine Guarding & Advanced LOTO 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. 机械防护里最优先覆盖的位置是？
Which position does machine guarding cover first?
2. LOTO 六步中，最常被跳过的两步是？
Which two LOTO steps are most often skipped?
3. 释放残余能量的正确做法，重力载荷对应的是？
For gravity loads, the correct way to deal with stored energy is?
4. 群体上锁中，控制锁（锁箱）应在什么条件下移除？
In group lockout, when may the control lock (lock box) be removed?
5. 联锁防护的固有弱点是？
The inherent weakness of an interlocked guard is?
错因归类 | Sort your misses
- 以为断电就万事大吉 → 每台设备先写能量清单，再谈隔离Assuming power-off settles everything → write an energy list for each machine before discussing isolation
- 把挂牌当保护 → 记住「锁是保护，牌是信息」Treating tagging as protection → remember 'locks protect, tags inform'
- 群锁用「代表锁」→ 每人一把锁，谁上锁谁解锁Using a 'representative lock' for group lockout → one lock per person; whoever locks it unlocks it
接下来学什么：下一块（Day 52–56）进入受限空间与动火作业：密闭环境里「能量」变成了缺氧、有毒气体与引燃源，隔离的对象从设备扩展到整个空间——进入许可、气体监测与救援安排将在同一张许可上交汇。
Next block (Days 52–56) moves to confined spaces and hot work: in an enclosed volume the 'energy' becomes oxygen deficiency, toxic gases and ignition sources, and isolation extends from machines to the whole space — entry permits, gas monitoring and rescue converge on one permit.
