第 14 块 · Domain 1 · 安全原理高级应用 · 25%Block 14 · 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「过程安全管理」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 Process Safety Management 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

    某涂料厂反应釜工序：三个月前为提产能把搅拌桨转速从 60 rpm 调到 90 rpm（仪表组直接改了变频器参数）；上个月催化剂供应商更换了配方（含新的放热峰）。两件事都没走 MOC。本周混料时温度超限报警两次，操作工按老规程「手动冷却」处理了。

    A coatings plant reactor: three months ago agitator speed went from 60 to 90 rpm for throughput (instruments changed the drive parameters directly); last month the catalyst supplier changed formulation (a new exotherm peak). Neither went through MOC. This week two high-temperature alarms fired during mixing, and operators followed the old procedure: 'manually cool'.

    1. 第一步：识别缺口——两处变更均未走 MOC，且叠加效应（更高转速 + 新放热峰）从未被评估 — Step 1 — name the gaps: two changes bypassed MOC, and their combined effect (higher speed + new exotherm) was never assessed
    2. 第二步：评估现状危险——放热失控的前兆（温升报警）已出现两次而程序未更新，属过程安全重大隐患；立即恢复原始参数并暂停生产 — Step 2 — judge the present danger: two precursor alarms with outdated procedures is a major process-safety signal; restore original parameters and stop production
    3. 第三步：系统性修复——两项变更补走 MOC（含 PHA 重评与操作规程/培训更新）；「手动冷却」应急路径写成正式异常处置规程并演练；仪器参数修改权限收紧 — Step 3 — fix the system: retrofit MOC on both changes (PHA revalidation, procedure and training updates); make 'manual cooling' a formally trained abnormal-situation procedure; lock down parameter-change rights

    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「变更叠加」与第一动作：先降险，再补文件。
    Tests change stacking and the first move: reduce risk before paperwork.

    按上述三步，本周的**第一**动作是？

    Following the three steps, what is the first action this week?

    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. 为该厂写一条「参数修改权限」规则（谁、什么范围、留什么记录）。
    Draft a parameter-change authority rule for this plant: who, what range, what records.
