本课只做一件事：拿「受限空间与动火作业」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 Confined Space & Hot Work 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

    市政污水检查井清淤：井深 4 m，直径 1.2 m，井壁爬梯；上个月曾因上游工厂排放导致 H₂S 超标。承包商计划两人进入、一人在地面「看一眼」。你作为 CSP 负责审核方案。

    Sludge removal from a 4 m deep, 1.2 m municipal wet well with a wall ladder; last month an upstream discharge pushed H₂S over limits. The contractor plans two entrants and one person 'keeping an eye out' at grade. You review the plan as the CSP.

    1. 第一步：定性——封闭、有限进入、有大气危险的明确历史 → 许可空间，「看一眼」不构成监护 — Step 1 — classify: enclosed, limited entry, a documented atmospheric history → permit space; 'keeping an eye out' is not an attendant
    2. 第二步：要求许可要素——隔离上游来水与电源、按顶中底监测 O₂/LEL/H₂S、机械通风、持续监测、进入主管签发 — Step 2 — demand the permit elements: isolate upstream flow and power, test O₂/LEL/H₂S at three levels, mechanical ventilation, continuous monitoring, entry supervisor signs
    3. 第三步：救援前置——三脚架绞盘与撤离绳在入口就位、监护人培训到位、专业救援队联系方式写在许可上；缺任一项不批 — Step 3 — rescue first: tripod winch and retrieval line rigged at the opening, a trained attendant on duty, the rescue team's contact on the permit; withhold approval if any piece is missing

    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「审方案」视角：从纸面找出会导致死亡的那一行。
    Tests the reviewer's eye: find the line on paper that kills.

    该方案最不可接受的一点是？

    Which single flaw in the contractor's plan is least acceptable?

    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. 写出你会写进「不予批准」意见的五个理由。
    Draft the five reasons you would write into a rejection of this plan.

    2. 把该井的动火场景叠加进来：若须井内焊接，许可要加哪些条？
    Now stack hot work in this well: what must the permit add?
