能量与事故因果 · 要点进阶 | Energy & Accident Causation · Key Points in Depth

第 2 块 · 备考基线 · Exam Baseline第 2 / 5 课 · 要点进阶Lesson 2 of 5 · Key Points in Depth

本课只做一件事：把「能量与事故因果」的四条要点逐条拆开：机制是什么、什么时候成立、最容易错在哪。

Take the four key points of Energy & Accident Causation apart: mechanism, conditions, and the usual misread.

本课不涉及：不重复概念定义，也不做综合题——只把要点讲透。
Not covered here: No repeat of definitions, no mixed questions — just the points, in depth.

本课目标 | Learning objectives

  1. 按顺序复述四条要点各自的机制
  2. 对每条要点说出一个常见误解，并说明为什么错
  3. 判断一个新例子属于哪一条要点

  • Recite the mechanism behind each of the four points
  • Name one common misread per point and why it fails
  • Classify a new example under the right point

    要点逐条拆 | Point by point

    1. 因果链三层：直接 ← 间接 ← 根本
    Three layers of the causal chain: direct <- indirect <- root
    直接原因是能量接触（模具砸到脚），间接原因是让它发生的管理缺陷（换模程序缺失），根本原因是系统因素（变更管理形同虚设）。调查如果停在第一层，措施就只会是「再培训一遍」。
    Direct cause is energy contact; indirect causes are the management deficiencies that allowed it; root causes are system factors. Stop at layer one and the action plan is 'retrain' again.
    常见误解 / Common misread：把「工人没戴防砸鞋」当根本原因写进报告——那是直接原因的近邻，不是系统因素。
    Writing 'worker was not wearing metatarsal guards' as the root cause — that is adjacent to the direct cause, not a system factor.
    2. 十大危险能量源是检查清单，不是背诵题
    The ten hazardous energy sources are a checklist, not a memory list
    重力、机械、电气、热、化学、声、气动、液压、辐射、生物。用途是扫现场：任何作业先问「这里有哪些能量？」——漏掉一种能量，就漏掉一整层屏障。
    Gravity, mechanical, electrical, thermal, chemical, sound, pneumatic, hydraulic, radiation, biological. Use it as a field sweep: ask what energies are present — miss one and you miss a whole barrier layer.
    常见误解 / Common misread：只盯着电气和机械。重力是最常见的杀人能量（高处坠落、物料滑落），气动/液压残压是检修伤亡的经典来源。
    Fixating on electrical and mechanical. Gravity is the most common killer; trapped pneumatic/hydraulic pressure is a classic maintenance fatality source.
    3. 海因里希 1:29:300 的用途是「预警」，不是「预测」
    Heinrich's 1:29:300 is for early warning, not forecasting
    1 起重伤背后约有 29 起轻伤、300 起未遂。它告诉你未遂事件是免费的预警信号，管理未遂比管理后果便宜得多。它不是一个稳定比率，不能用来推算下一起重伤。
    Roughly 29 minor injuries and 300 near misses sit under one major injury — near misses are free early warnings, far cheaper to manage than outcomes. It is not a stable ratio for forecasting.
    常见误解 / Common misread：把 1:29:300 当精确公式，用「我们已经 300 天无事故」推断安全——正是该比例要反对的思维。
    Treating 1:29:300 as a precise formula and declaring safety because the counter says 300 days without injury — exactly the thinking the pyramid argues against.
    4. Swiss Cheese：事故 = 多层漏洞排成一条线
    Swiss Cheese: an accident = holes aligning across layers
    每层防御都有洞（设计缺陷、程序漏洞、监督盲区、注意力波动）。事故不是单点失效，是四层洞恰好对齐。所以根因分析问的不是「谁失手」，而是「为什么系统允许一次失手直达伤害」。
    Every layer has holes (design, procedure, supervision, attention). Accidents are aligned holes, not single failures — RCA asks why the system let one slip reach the body.
    常见误解 / Common misread：以为加一层「再培训」就补上了洞。洞的对齐才是关键：少一层独立屏障，对齐概率就上一个数量级。
    Assuming one more training closes a hole. Alignment is what matters: remove one independent layer and the odds jump by an order of magnitude.

    考点应用Exam-point application

    这道题考什么：考「干预层级」：能否把一道直觉题转成因果链定位题。
    Tests intervention level: turning an intuitive item into a causal-chain question.

    叉车频繁撞坏货架。已经反复培训司机仍有事故，按因果链，下一步最该查什么？

    Forklifts keep striking racking despite repeated driver training. Per the causal chain, what should be examined next?

    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. 列出你工作区的 5 种能量源，各配一句「失控时会发生什么」。
    List five energy sources in your work area, each with one line on what uncontrolled release would do.
