本课只做一件事：把「机械防护与进阶上锁挂牌」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 Machine Guarding & Advanced LOTO 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

    Point of Operation / 作业点
    机器对材料执行加工动作的位置——冲、剪、折、成型都发生在这里，是防护最优先覆盖的位置。
    Where the machine works the material — stamping, shearing, bending, forming — the first priority for guarding.
    易混 / Easily confused：与动力传动部位不同：传动部位伤人的方式是卷入，作业点是成型动作本身。
    Not the power transmission area: transmission nips and wraps; the point of operation is the forming action itself.
    例句 / In a sentence：The guard opens only at the point of operation. / 护罩只在作业点开口。
    Interlocked Guard / 联锁防护
    防护装置与机器控制回路联锁：防护打开或未复位时机器不能运行。
    A guard tied into the control circuit so the machine cannot run when the guard is open or not reset.
    易混 / Easily confused：与固定式防护不同：联锁有控制回路，存在电气失效与被绕过的问题，须定期检验失效模式。
    Not a fixed guard: interlocks carry a control circuit with electrical failure and bypass modes that need periodic testing.
    例句 / In a sentence：The interlocked guard failed its quarterly test. / 联锁防护未通过季度测试。
    Stored Energy / 残余（储存）能量
    隔离后仍留在系统里的能量：气压、液压、电容、弹簧、提升的负载。
    Energy left in the system after isolation: air, hydraulic pressure, capacitors, springs, raised loads.
    易混 / Easily confused：与「电源」不同：电源靠隔离消除，残能靠释放或抑制消除，重力靠垫块抑制。
    Not the power source: isolation removes sources; stored energy is released or restrained, gravity is cribbed.
    例句 / In a sentence：Bleed the stored energy before opening the line. / 开管路前先泄掉残能。
    Lockout vs Tagout / 上锁与挂牌
    上锁用物理锁具阻止能量隔离装置被操作；挂牌提供警示与归属信息。上锁是保护，挂牌只是告知。
    Lockout physically prevents operation of the energy-isolating device; tagout warns and identifies. The lock protects; the tag only informs.
    易混 / Easily confused：与「只挂牌不上锁」不同：标签可以被移除、可以被忽略，它不提供任何物理保护。
    Not tag-only: a tag can be removed or ignored and provides no physical protection.
    例句 / In a sentence：Tagout alone is allowed only when lockout is infeasible. / 只有无法上锁时才允许仅挂牌。
    Group Lockout / 群体上锁
    用锁箱或锁排让每名作业者对同一组能量隔离装置各自上锁，谁上锁谁解锁。
    A lock box or hasp lets each worker attach a personal lock to one isolation set; whoever locks, unlocks.
    易混 / Easily confused：与「代表上锁」不同：任何人的锁都不能代表另一个人，包括班组长。
    Not representative locking: no one's lock stands for another's, including the supervisor's.
    例句 / In a sentence：Group lockout covered the night crew's latecomers. / 群锁覆盖了夜班中途加入的人。
    Verification (Try-out) / 验证（试启动）
    上锁后用试启动、测电压、看表压等方式证实零能量；验证须覆盖每一种被隔离的能量。
    After locking, prove zero energy by try-start, voltage test or gauge reading — for every isolated energy.
    易混 / Easily confused：与「目视确认」不同：验证是操作性与测量性动作，必须留下可核查的证据。
    Not a visual check: verification is operational and measured, and must leave auditable evidence.
    例句 / In a sentence：Try-out confirmed zero energy on all three sources. / 试启动证实三种能量均为零。

    情景自测 | Scenario check

    本课理解Lesson comprehension

    这道题考什么：考上锁与挂牌的本质差别：一个是物理保护，一个是信息。
    Tests the essence: a lock is protection, a tag is information.

    某工厂能量控制程序允许「仅挂牌」用于气动回路维修。以下哪一项是它必须同时具备的前提？

    A plant's energy control program allows tagout-only for pneumatic repairs. What must it also ensure?

    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 Lockout 与 Tagout 写一张对比卡：保护方式、失效模式、何时允许只用挂牌。
    Write a comparison card for lockout vs tagout: protection, failure mode, when tag-only is allowed.
