能量与事故因果 · 术语精讲 | Energy & Accident Causation · Glossary Focus

第 2 块 · 备考基线 · Exam Baseline第 3 / 5 课 · 术语精讲Lesson 3 of 5 · Glossary Focus

本课只做一件事：把「能量与事故因果」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 Energy & Accident Causation 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

    Hazardous Energy / 危险能量
    可能造成伤害的能量或危险物质：重力、机械、电气、热、化学、声、气动、液压、辐射、生物十类。
    Energy or hazardous material capable of harm: gravity, mechanical, electrical, thermal, chemical, sound, pneumatic, hydraulic, radiation, biological.
    易混 / Easily confused：与 hazard（危害源）不同：能量是危害源「伤人」的机制，一个危害源可以同时携带几种能量。
    Not the same as hazard: energy is the mechanism of harm; one hazard may carry several energy types.
    例句 / In a sentence：The JSA listed all hazardous energy sources before maintenance began. / 检修前的 JSA 列全了危险能量种类。
    Energy Barrier / 能量屏障
    设在能量与人体之间、阻止失控转移的任何屏障：防护罩、联锁、隔离、距离、时间、浓度限制。
    Anything placed between energy and body to stop uncontrolled transfer: guards, interlocks, isolation, distance, time limits, concentration limits.
    易混 / Easily confused：与 control measure 近义但更具体——屏障强调「物理或程序上确实隔开了能量」，喊口号不算屏障。
    Close to control measure but stricter: a barrier must actually separate energy from body; slogans do not count.
    例句 / In a sentence：The interlock is the last energy barrier before the operator's hands. / 联锁是工人双手前最后一道能量屏障。
    Near Miss / 未遂事件
    没有造成伤害但本可能造成的 events；海因里希金字塔的底座，最便宜的预警信号。
    An event with no injury this time but real potential; the base of the Heinrich pyramid and the cheapest early warning.
    易混 / Easily confused：与 first aid case 的分界是「是否已造成需要处理的伤害」；未遂是零伤害、高潜能。
    Differs from a first aid case by outcome: a near miss causes zero injury with high potential.
    例句 / In a sentence：Report the near miss, not just the injury. / 未遂也要上报，不只是伤害。
    Root Cause / 根本原因
    系统层面允许事故发生的因素：设计、程序、资源、文化。纠正它能让同类事故整体减少。
    The system-level factor that allowed the event: design, procedure, resources, culture. Fixing it reduces whole classes of events.
    易混 / Easily confused：与 direct cause（直接原因）相对。考试里「哪个是根本原因」的答案几乎从不落在工人行为上。
    Opposite of direct cause: in exams, the root cause is almost never an individual worker's act.
    例句 / In a sentence：The root cause was a permit system that skipped energy verification. / 根本原因是许可制度跳过了能量验证。
    Swiss Cheese Model / 瑞士奶酪模型
    把多层防御画成多片奶酪，每片的洞是潜在失效；事故是洞排成一条线的结果。
    Defenses drawn as cheese slices, each with holes (latent failures); an accident is holes lining up.
    易混 / Easily confused：与 Heinrich Pyramid 不同：金字塔讲数量比例（未遂:伤害），奶酪讲层次对齐（防御结构），两者互补。
    Not the Heinrich pyramid: the pyramid is about counts (near miss to injury), the cheese about aligned layers.
    例句 / In a sentence：Swiss cheese analysis showed three defenses failed the same afternoon. / 奶酪分析显示三道防线同一天失效。
    Defense in Depth / 纵深防御
    故意叠多层相互独立的屏障，任何单层失效都不导致伤害。
    Deliberately stacking independent barriers so no single failure causes injury.
    易混 / Easily confused：关键词是「独立」：三道屏障共享同一个电源就不算纵深，一断全断。
    The keyword is independence: three barriers sharing one power supply are not depth — one trip kills all.
    例句 / In a sentence：Guard, interlock and lockout give defense in depth. / 防护罩、联锁、上锁构成纵深防御。

    情景自测 | Scenario check

    考点应用Exam-point application

    这道题考什么：考术语辨析：Heinrich 与 Swiss Cheese 的分工，考试爱把它们混在一组选项里。
    Terminology discrimination — exams love mixing Heinrich and Swiss cheese in one option set.

    「把每层防御的失效画成洞，分析洞如何对齐」描述的是哪个概念？

    Which concept describes defenses as layers with holes whose alignment causes accidents?

    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. 以「更换注塑机模具」这道工序为例（断电上锁后仍存在模具自重、液压残压、吊装三种能量），为它写三层独立屏障，并回答「哪两层共享同一失效模式」。写完后，把同一套思路换成你现场的一道工序再做一遍。
    Work this example: changing an injection-mold die (after lockout, three energies remain - the die's own weight, trapped hydraulic pressure, and the crane lift). Write three independent barriers for it, then name the two that share a failure mode. Afterwards, repeat the same steps for one task in your own workplace.
