本课只做一件事：拿「职业暴露控制基础」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 Occupational Exposure Control Basics 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

    家具厂喷漆房：工人呼吸带甲苯 TWA 120 ppm（8 小时个体采样），定点短时读数 300 ppm（清洗时段）。PEL（TWA）200 ppm；TLV 20 ppm；STEL 无。工厂现有两副半面罩滤毒盒。业主问：「我们合法吗？要不要买供气式呼吸器？」

    A furniture paint shop: the painter's breathing-zone toluene TWA is 120 ppm (8-hour personal sample); a fixed-point short reading hit 300 ppm during gun cleaning. PEL (TWA) 200 ppm; TLV 20 ppm; no STEL. The shop owns two half-mask cartridges. The owner asks: 'Are we legal? Should we just buy supplied-air respirators?'

    1. 第一步：把数字放对位置——120 ppm 是合法的（< PEL 200），但对照健康目标 TLV 20，比值 6.0；清洗时段 300 ppm 要另做 15 分钟 STEL 型评估 — Step 1 — place the numbers: 120 ppm is legal (< PEL 200) but six times the health target (TLV 20); the 300 ppm cleaning episode needs its own short-task evaluation
    2. 第二步：按层级回答「要不要呼吸器」——先替代（水基或高固含漆）与工程（补齐喷房 LEV、清洗工位单独捕集），两步之后复测 — Step 2 — answer the respirator question by hierarchy: substitute first (waterborne or high-solids paint) and engineer next (restore booth LEV, add capture at the cleaning station), then resample
    3. 第三步：过渡期兜底——复测前使用过滤式半面罩（滤毒盒更换计划 + 适合性检验），并明确它只是过渡措施 — Step 3 — bridge control: interim half-mask cartridges with a change-out schedule and fit testing, explicitly temporary

    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「合法 ≠ 可接受」与层级顺序：这是工业卫生题的核心价值观。
    Tests legal-versus-acceptable and the hierarchy order — the block's core value.

    按上述三步，最合理的答复是？

    Following the three steps, what is the best answer to the owner?

    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. 为这个喷漆房写一份 5 行的整改优先级清单（含复测节点）。
    Draft a five-line remediation priority list for this shop, with a resampling checkpoint.
