CSP Day 100 · Domain 1 Capstone Cases

第 19 块 · Domain 1 · 安全原理高级应用 · 25%Block 19 · Domain 1 · Advanced Application of Safety Principles · 25%第 4 / 5 课 · 情景应用Lesson 4 of 5 · Scenario in Action

本课只做一件事：拿「Domain 1 综合应用与案例」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 Domain 1 Capstone Cases 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

按三步走完一个场景，并说出每一步的依据
区分「更有效」与「更先做」两类答案
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

屋顶通风机检修：小雨、屋顶临边无护栏、风机传动带护罩已拆但配电柜未上锁，维修工带着工具包到达屋面。三个危害并存：雨天湿滑（环境）、临边坠落（生存）、传动带意外启动（能量）。

Rooftop fan repair: light rain, an unguarded roof edge, fan guards removed but the disconnect not locked out; a mechanic arrives with tools. Three hazards coexist: wet surfaces (environment), the open edge (survival), unexpected start-up (energy).

第一步：环境风险先行——雨中湿滑的屋面上做任何事都在放大坠落后果，第一动作是停止雨中作业（等待或推迟） — Step 1 — environment first: working wet on a roof amplifies the fall consequence; the first act is stopping work in the rain (wait or postpone)
第二步：临边防护——护栏或 PFAS 挡住生存级风险；第三步：上锁挂牌并验证零能态，之后才动手检修 — Step 2 — edge protection (guardrail or PFAS) against the survival-level risk; Step 3 — lockout with zero-energy verification before touching the machine
答案与依据：正确顺序是「停雨天作业 → 装护栏 → 上锁检修」。依据是层级思想与复合危害排序口诀：环境先行、生存次之、能量再次。把顺序调换的选项都是在「活下来」之前先「干活」。 — Answer and basis: stop work in the rain, then edge protection, then lockout. The hierarchy and the cross-hazard rule decide: environment first, survival second, energy third — reordered options work before surviving.

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：考复合危害的排序：环境→生存→能量。
Tests cross-hazard ordering: environment, survival, energy.

前三个动作按顺序是？

What are the first three actions, in order?

A. 先上锁、再停雨天作业、后装护栏 Lock out first, then stop for rain, then fit a guardrail B. 停雨天作业、装护栏、再上锁检修 Stop for rain, fit the guardrail, then lock out and repair C. 先装护栏、后上锁、雨继续干 Fit the guardrail, lock out, and keep working in the rain D. 边锁边装护栏 Lock out and fit the rail at the same time
