能量与事故因果 · 情景应用 | Energy & Accident Causation · Scenario in Action

第 2 块 · 备考基线 · Exam Baseline第 4 / 5 课 · 情景应用Lesson 4 of 5 · Scenario in Action

本课只做一件事：拿「能量与事故因果」做一次真实判断：按步骤走完，答案由推导得出而不是靠回忆。

Use Energy & Accident Causation in one real decision: follow the steps, derive the answer instead of recalling it.

本课不涉及：不新讲概念，也不做多题连练——只走一个场景。
Not covered here: No new concepts, no question drills — one scenario, walked through.

本课目标 | Learning objectives

  1. 按三步走完一个场景，并说出每一步的依据
  2. 区分「更有效」与「更先做」两类答案
  3. 把结论写回自己的术语表

  • Walk a scenario in three steps and justify each
  • Separate the more effective answer from the earlier step
  • Write the conclusion back into your glossary

    场景走一遍 | Walk the scenario

    压机车间：换模工人在模具下方调整定位块时，模具从滑道滑落，将其小腿夹伤。调查发现：换模程序没有「支撑模具」步骤；能量隔离只做了断电，模具自重（重力势能）从未被处理；班组长默许「快换」跳步骤。

    Press shop: while a die setter adjusted locating blocks under the mold, the mold slid off the chute and crushed his lower leg. Findings: no mold-supporting step in the die-change procedure; energy isolation stopped at electrical disconnect, never addressing the mold's own weight (gravitational energy); the supervisor tolerated shortcut 'quick changes'.

    1. 第一步：先问「伤人的是什么能量」——重力势能，不是电流 — Step 1 — name the injuring energy: gravity, not electricity
    2. 第二步：按因果链分层——直接（模具滑落）→间接（程序无支撑步骤）→根本（变更与监督体系默许跳步） — Step 2 — layer the chain: direct (mold slid) → indirect (no support step) → root (system tolerated shortcuts)
    3. 第三步：干预对准能量本身——机械支撑（支撑销/锁块）优先于任何培训 — Step 3 — aim the intervention at the energy: mechanical positive support (pins/blocks) before any training

    走完这三步再往下答题；答案不是背出来的，是按步骤推出来的。/ Work the three steps before answering — the answer is derived, not recalled.

    情景自测 | Scenario check

    考点应用Exam-point application

    这道题考什么：考「最根本的干预」：用能量理论排除掉所有不碰能量的选项。
    Tests the most fundamental intervention by eliminating anything that never touches the energy.

    按能量意外释放理论，防止此类事故再发生的最根本干预是？

    Per energy release theory, the most fundamental intervention is:

    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. 给这道压机事故写「四段时间线」：能量积累→失控→转移→伤害，每段标一个可用屏障。
    Draw the four-stage timeline for this press incident — build-up, loss of control, transfer, harm — with one barrier per stage.
