本课只做一件事：把「高处作业与坠落防护」的 6 个高频英文术语从「眼熟」变成「能用」：定义、易混、例句。

Turn the six high-frequency terms of Work at Height & Fall Protection from familiar to usable: definition, look-alike, example.

本课不涉及：不扩到别的板块的术语，也不考题型技巧。
Not covered here: No terms from other blocks, no question-technique work.

本课目标 | Learning objectives

  1. 为每个术语说出定义，而不是只给中文对应词
  2. 指出每一对易混词差在哪一个限定条件上
  3. 把每个术语放进一句真实的现场英文里

  • Define each term rather than translate it
  • Point to the exact qualifier that separates each look-alike pair
  • Put each term into one real site sentence

    术语详解 | Glossary in depth

    PFAS / 个人坠落制动系统
    锚点 + 全身式安全带 + 连接件（挂绳、缓冲包、自锁钩）组成的系统，在坠落发生时把冲击力与距离控制在可生存范围。
    Anchorage + full-body harness + connector (lanyard, shock absorber, self-locking snap) that keeps arrest forces and distance survivable when a fall occurs.
    易混 / Easily confused：与 restraint system（限制系统）不同：限制用定长绳防止到边缘，坠落根本不发生；制动允许坠落。
    Not a restraint system: restraint with a fixed-length lanyard prevents reaching the edge at all; arrest allows the fall.
    例句 / In a sentence：Inspect the PFAS before every use. / 每次使用前检查整套坠落制动系统。
    Anchor Point / 锚点
    能承受 5,000 lb（或工程师按 2 倍最大制动力核定）的挂点，位置应尽量在作业点正上方。
    A tie-off point rated for 5,000 lb (or engineer-qualified to twice the maximum arrest force), ideally directly overhead.
    易混 / Easily confused：与「看起来结实的结构」不同：管道、栏杆、吊顶龙骨都不是合格锚点，除非经过核定。
    Not 'anything that looks solid': pipe, railings and ceiling grids are not anchors unless qualified.
    例句 / In a sentence：The anchor point was engineered, not improvised. / 锚点是经过核定的，不是临时找的。
    Free Fall Distance / 自由落体距离
    从失去支撑到缓冲包开始作用的下坠距离，OSHA 限 6 ft。
    The drop from loss of support until the deceleration device engages; OSHA caps it at 6 ft.
    易混 / Easily confused：与 total fall distance（总坠落距离）不同：总距离还要加缓冲展开与人体位移。
    Not total fall distance: the total adds deceleration deployment and body displacement.
    例句 / In a sentence：Foot-level tie-off increases free fall distance. / 脚部挂点会加大自由落体距离。
    Fall Clearance / 净空
    坠落路径上无障碍的最小竖直距离，必须大于总坠落距离加安全余量（≥ 3 ft）。
    The unobstructed vertical distance on the fall path, exceeding total fall distance plus margin (≥ 3 ft).
    易混 / Easily confused：与 drop（落差）不同：落差是屋面到地面的高度，净空是「人挂上之后头朝下会到哪里」。
    Not the drop: the drop is roof-to-ground; clearance is where the inverted worker ends up.
    例句 / In a sentence：Clearance was verified against the lowest structure. / 净空对照最低结构核验过。
    Swing Fall / 摆荡坠落
    锚点偏离作业点时，坠落后像钟摆一样荡向结构。挂点越高、越接近正上方，摆荡越小。
    When the anchor is off-axis, the faller pendulums into structure. The higher and more overhead the anchor, the smaller the swing.
    易混 / Easily confused：与净空不足是两个独立失败模式：净空够也可能撞上侧面结构。
    Separate from insufficient clearance: clearance can be adequate yet the swing still strikes a side structure.
    例句 / In a sentence：A twin-leg lanyard keeps the anchor overhead while moving. / 双腿挂绳保证移动中锚点始终在上方。
    Suspension Trauma / 悬挂创伤
    坠止后直立悬挂导致腿部血液淤积、回心血量下降，可在数分钟至数十分钟内失去意识；救援须尽快解除悬挂并水平化。
    Upright suspension after arrest pools blood in the legs and can cause unconsciousness within minutes; rescue must relieve the suspension and horizontalise promptly.
    易混 / Easily confused：与坠落冲击伤不同：悬挂创伤发生在「已经安全接住之后」，所以救援计划是系统的一部分。
    Not an impact injury: it happens after a successful arrest, which is why rescue is part of the system.
    例句 / In a sentence：Suspension trauma straps are for post-arrest use. / 悬挂解除脚踏带是坠止后用的。

    情景自测 | Scenario check

    本课理解Lesson comprehension

    这道题考什么：考术语的限定条件：限制系统与制动系统的分界词是「定长」。
    Tests the qualifier: 'fixed-length' separates restraint from arrest.

    一名工人在距屋面边缘 3 ft 处作业，屋面边缘外就是 40 ft 落差。用 2.5 ft 定长挂绳把安全带连到核定的屋面锚点上。这个配置属于？

    A worker is 3 ft from a roof edge with a 40 ft drop, tied to a qualified roof anchor with a 2.5 ft fixed-length lanyard. What is this configuration?

    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. 为 Fall Clearance 和 Free Fall Distance 各写一张三层卡，例句用你自己的场景。
    Write a three-layer card each for Fall Clearance and Free Fall Distance, with your own site example.

    2. 写出三项「挂上前检查」：每项一句话，说明漏掉会怎样。
    Write three pre-tie-off checks, one line each, stating what a miss would cause.
