本课只做一件事：把「PHA 与 HAZOP」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 PHA & HAZOP 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

    HAZOP / 危险与可操作性分析
    以引导词×参数系统生成偏差、逐条找原因后果的结构化工艺危害分析方法。
    A structured process hazard method that generates deviations from guide words times parameters and works each to causes and consequences.
    易混 / Easily confused：易混：HAZOP 与 JHA。HAZOP 面向工艺与设备，JHA 面向人的作业步骤。
    Confused with JHA: HAZOP addresses process and equipment, JHA human task steps.
    例句 / In a sentence：Systematic, not brainstorm. / 是系统过格，不是头脑风暴。
    Guide Word / 引导词
    描述偏差方向的词：无、多、少、反向、异常、部分。
    A word describing the direction of deviation: none, more, less, reverse, abnormal, part of.
    易混 / Easily confused：易混：引导词与原因。引导词只说明「怎么偏」，不解释「为什么偏」。
    Confused with cause: a guide word says how, never why.
    例句 / In a sentence：How, not why. / 只管方向，不管原因。
    Node / 节点
    HAZOP 分析单元，按功能切分，设计意图可用一句话表述。
    The HAZOP analysis unit, split by function so design intent fits one sentence.
    易混 / Easily confused：易混：节点与 P&ID 分区。分区是绘图便利，节点是分析逻辑。
    Confused with drawing zones: zones aid drafting, nodes aid analysis.
    例句 / In a sentence：One intent, one node. / 一句意图，一个节点。
    Deviation / 偏差
    参数偏离设计意图的状态，由引导词与参数组合而成，如「流量无」。
    A parameter off design intent, formed by guide word plus parameter, as 'no flow'.
    易混 / Easily confused：易混：偏差与后果。偏差是状态，后果是伤害与损失。
    Confused with consequence: a deviation is a state, a consequence is harm or loss.
    例句 / In a sentence：State before harm. / 先有状态，后有伤害。
    Safeguard / 保护措施
    独立于原因、可试验、能在偏差发展成后果前介入的工程或管理措施。
    An engineered or administrative measure, independent of the cause and testable, that intervenes before the deviation becomes a consequence.
    易混 / Easily confused：易混：保护与操作规程。规程只有在被遵守且可监督时才算保护。
    Confused with procedure: a procedure counts only if followed and verifiable.
    例句 / In a sentence：Independent and testable. / 既独立又可试验。
    Revalidation / 再验证
    按周期或触发条件对既有 PHA 重做，确认假设仍成立、建议仍有效。
    Redoing an existing PHA on a cycle or trigger to confirm assumptions and recommendations still hold.
    易混 / Easily confused：易混：再验证与更新。更新只改文字，再验证重走分析。
    Confused with updating: updating edits text, revalidation re-walks the analysis.
    例句 / In a sentence：Five years or on change. / 五年一周期，变更即触发。

    情景自测 | Scenario check

    术语辨析Terminology

    这道题考什么：考保护措施的成立条件。
    Tests when a safeguard counts.

    下列哪项最能称为合格保护措施？

    Which best qualifies as a safeguard?

    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. 为三个已有保护措施打「独立/可测」两个勾，挑出不合格的。
    Score three existing safeguards for independence and testability, then flag the weak one.
