本课只做一件事：搞清「高处作业与坠落防护」到底是什么、为什么考试要先过这一关、它管到哪里为止。

Get clear on what Work at Height & Fall Protection really is, why it comes first, and where it stops.

本课不涉及：不展开细节与题目——那是第 2–5 课的事。
Not covered here: No detail, no questions — those are lessons 2 to 5.

本课目标 | Learning objectives

  1. 能用一句话说清「高处作业与坠落防护」解决的是什么问题
  2. 能举出一个「不懂它就一定做错」的例子
  3. 知道本课的边界，不把后续课的内容提前混进来

  • State in one sentence the problem Work at Height & Fall Protection solves
  • Give one example where missing it guarantees a wrong answer
  • Know this lesson's boundary and keep later lessons out

    它是什么 | What it is

    坠落防护回答一个问题：人在掉下去之前，系统替他接住的是什么。它有三根支柱——消除（把工作放回地面）、防坠落（护栏、护笼、限制系统，让人到不了边缘）、坠止（个人坠落制动系统 PFAS，允许坠落发生但把冲击力与坠落距离控制在可生存范围）。护栏防止坠落，PFAS 只保证坠落不致命——两者是不同等级的承诺。

    Fall protection answers one question: what catches the person before the ground does. Three pillars — elimination (move the work down), fall prevention (guardrails, restraint: keep people off the edge) and fall arrest (a personal system that lets the fall happen but controls force and distance to survivable levels). Guardrails prevent falls; PFAS only promises the fall is survivable — different commitments.

    为什么先学它 / Why first
    高处坠落是建筑业与一般工业的头号致命源，CSP 必考；而且它是控制层级最干净的例子：同一种能量（重力），消除最有效，护栏是不依赖人的工程屏障，PFAS 依赖穿戴者的每一个动作（选锚点、计算净空、检查装备）。前 36 天的模型在这里第一次被用来「设计」，而不是「解释」。
    Falls are the top killer in construction and a staple of general industry; the CSP tests them, and they are the cleanest hierarchy-of-controls example: same energy (gravity), elimination works best, guardrails are a passive barrier, PFAS depends on every action of the wearer. After 36 days of models, this is where the model is first used to design, not to explain.
    它管到哪里为止 / Where it stops
    本块不展开脚手架与梯子的验收细节（OSHA 1926 Subpart L / Subpart X 的具体条款），不推导锚点强度设计（5,000 lb 或 2 倍最大冲击是结论，不是推导），也不演练完整救援计划（情景题会给出条件）。
    This block does not cover scaffold and ladder acceptance detail (OSHA 1926 Subparts L and X), does not derive anchor design (5,000 lb or twice the maximum arrest force is a conclusion, not a derivation), and does not run a full rescue drill — scenario items will supply conditions.

    先认个脸 | Terms you will meet

    1. PFAS — 个人坠落制动系统
    2. Anchor Point — 锚点
    3. Free Fall Distance — 自由落体距离
    4. Fall Clearance — 净空
    5. Swing Fall — 摆荡坠落
    6. Suspension Trauma — 悬挂创伤

    这里只要求认得；定义、易混与例句在本块第 3 课「术语精讲」。/ Recognition only — definitions come in the glossary lesson of this block.

    情景自测 | Scenario check

    本课理解Lesson comprehension

    这道题考什么：考「防坠落」与「坠止」的等级差：这是本块所有题目的地基。
    Tests the gap between prevention and arrest — the foundation of every item in this block.

    项目方说：「全员配发全身式安全带与挂绳，坠落问题就解决了。」这句话错在哪里？

    A project owner says: 'We issued full-body harnesses and lanyards to everyone — falls are solved.' What is wrong?

    自编练习题，不是 BCSP 官方真题，也不能用来预测分数。 / Original practice item, not an official BCSP exam question.

    动手练 | Practice

    1. 用一句话说清「护栏」和「PFAS」对人的依赖度差别。
    State in one sentence how a guardrail and a PFAS differ in what they rely on.
