本课只做一件事：搞清「JHA/JSA 实操」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 JHA/JSA in Practice 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「JHA/JSA 实操」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 JHA/JSA in Practice 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

    作业危害分析（JHA）四步：拆步骤→辨危害→定控制→写交底。步骤拆 5–10 步最实用，颗粒度以「一个可观察的动作」为一步：太粗漏危害，太细没人用。危害识别三问：身体哪个部位暴露、接触什么能量、控制在何时会失控——三问套不上，说明这步没拆对。控制写入交底：每条控制要有执行人、执行时机与验证方式。JSA 与 JHA 同源，JSA 更强调人—任务界面（姿势、力度、节奏）。

    Job hazard analysis in four steps: break the task into steps, identify hazards, set controls, brief the crew. Five to ten steps works best; granularity is one observable action per step — coarser misses hazards, finer gets ignored. Three hazard questions: which body part is exposed, what energy is involved, when does control fail. If none of the three fits, the step is wrong. Controls go into the briefing with an owner, a timing and a verification. JSA is the same lineage with more emphasis on the person-task interface — posture, force, pace.

    为什么先学它 / Why first
    三个坑：只拆「干活」的步骤（漏掉准备与收尾）、把危害写成「注意安全」这类无法验证的句子、控制措施停在表格里没进交底。JHA 的价值不在文档，在班组会上被念出来并被理解。
    Three traps: breaking only the doing steps (missing setup and closeout), writing unverifiable hazards such as 'be careful', and leaving controls in the spreadsheet instead of the briefing. A JHA earns its keep when it is read aloud and understood at the crew talk.
    它管到哪里为止 / Where it stops
    本块不覆盖 HAZOP 与定量风险评价（下一块），不涉及具体行业专用 JHA 模板。
    This block skips HAZOP and quantitative assessment (next block) and industry-specific JHA templates.

    先认个脸 | Terms you will meet

    1. JHA — 作业危害分析
    2. Task Step — 任务步骤
    3. Hazard Identification — 危害识别
    4. Control Measure — 控制措施
    5. Pre-task Briefing — 班前交底
    6. Residual Risk — 剩余风险

    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：考危害识别三问的作用。
    Tests the role of the three hazard questions.

    写完一步 JHA，三问一个都答不上（不知哪个部位、什么能量、何时失控）。这说明？

    After writing a step, none of the three questions can be answered. That means?

    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. 为一项日常任务写完整 JHA（含准备与收尾步骤）。
    Write a full JHA for one routine task, including setup and closeout.
