本课只做一件事：拿「毒理学基础」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 Toxicology Fundamentals 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

    印刷车间 6 名操作工反映近月「下班后头晕、眼花」。车间接有：乙醇类清洗剂（敞口擦拭，车间气味明显）与异丙醇（IPA，班中擦版）；通风为屋顶一台老旧轴流风机。两台监测报告显示：乙醇 380 ppm（限值 1000 ppm）、IPA 150 ppm（限值 400 ppm）——单项全部合格。有人在群里说「数据合格，员工装病」。

    Six press operators report dizziness after shifts. In play: ethanol cleaner wiped from open trays and IPA for plate wiping, vented by one aging roof fan. Monitoring shows ethanol 380 ppm (limit 1000) and IPA 150 ppm (limit 400) — every single reading compliant. Someone posts: numbers are fine, the workers are faking.

    1. 第一步：审数据口径——两份报告只测了「定点、单物质、日均」；症状指向溶剂急性效应，而敞口擦拭的真实暴露在呼吸带与任务峰值，定点日均值会漏掉擦拭瞬间的高峰。先补「个体+任务峰值」采样 — Step 1 — audit the data: area, single-substance, daily averages only; the symptoms point to acute solvent effect while open wiping creates breathing-zone task peaks that averages miss. Order personal, task-peak sampling
    2. 第二步：混合物相加评价——乙醇与 IPA 同为醇类、靶器官相同（中枢神经），按相加原则：380/1000 + 150/400 = 0.38 + 0.375 = 0.755，虽未超 1 但已用掉四分之三「配额」，且这是被低估的日均值——真实峰值大概率越线 — Step 2 — additive mix: both are alcohols hitting the central nervous system; 380/1000 plus 150/400 equals 0.755 — three quarters of the quota on understated averages, so real peaks likely cross the line
    3. 第三步：立即措施与根治——立即：密闭清洗剂容器、擦拭改用带盖分配器、故障风机抢修并装局部排烟罩；短期：提供活性炭呼吸防护过渡；根治：把「敞口擦拭」改为定量点注+密闭擦拭系统，重测呼吸带个体样后按统计判定关闭问题 — Step 3 — act then fix: seal containers, lidded dispensers, repair the fan and add local exhaust now; offer carbon respirators as a bridge; root fix is metered dispensing plus closed wiping, then re-sample breathing-zone personal data and close statistically

    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：考混合物相加与数据口径。
    Tests additive mixtures and data scope.

    单项监测全部合格但员工有症状，正确的第一步是？

    All single-substance readings pass yet workers have symptoms. The right first step?

    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. 写一页「单项合格≠整体安全」的技术说明。
    Draft a one-pager: single-agent compliance is not mix safety.
