场景走一遍 | Walk the scenario

厂内装卸区，一辆槽罐车正在卸甲苯（UN 1294，易燃，蒸气重于空气）。操作工报告「卸料软管接口渗漏，地面有一小滩液体，闻到味道」。当时微风，风向不定。罐内还有约 20 吨。你是值班 EHS。

At the loading rack a tanker is unloading toluene (UN 1294, flammable, vapour heavier than air). An operator reports a weeping hose connection, a small pool and detectable odour. Breeze is light and shifting; about twenty tonnes remain aboard. You are the duty EHS.

1. 第一步：立即停止与拉距——叫停卸料（紧急切断阀）、断开可能的点火源（车辆熄火、禁动火、手机管制）；人员撤到上风向高地并划初始警戒（按 ERG 1294 的初始隔离距离，宁大勿小——风不定时按最坏方向扩）；通知消防与 CHEMTREC/供应商应急号 — Step 1 — stop and stand off: hit the emergency shutoff, kill ignition sources — engine off, no hot work, phone restrictions; withdraw upwind and uphill, draw the cordon at the ERG distance for 1294, sized to the worst direction since wind is shifting; call fire and the supplier's emergency line
2. 第二步：识别与判断升级——远距离确认 UN/品名/装载量（运输文件）；评估泄漏速率与蒸气积聚地形（装卸区低洼+重气=风险放大）；判定当前响应级别：操作级防御（围堵沟/覆盖泡沫由消防做），我方无人进热区 — Step 2 — identify and assess: confirm UN, product and quantity from the papers; weigh the terrain — a low rack with heavy vapour amplifies risk; set the response tier as operations-level defense — dikes and foam are fire's job, nobody enters the hot zone
3. 第三步：统一指挥与收尾——消防到场后统一指挥：我方提供 SDS/工艺信息/厂区地图，消防主导堵漏与泡沫；接管后重点转为去污与恢复：受污染土壤/水收集、去污线撤收条件（检测合格）、事故后复训与防再发（卸料接口改干式断接） — Step 3 — unified command and close: on fire's arrival form unified command — we supply SDS, process info and maps, they lead plugging and foam; the focus turns to decon and recovery: contaminated soil and water captured, line stand-down on clearance readings, then lessons into training and dry-break couplings

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：考重气+风向不定的警戒扩展。
Tests cordons under shifting wind.

风向不定时，初始警戒圈应按什么原则画？

With the wind shifting, how should the initial cordon be drawn?

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. 给装卸区写「泄漏前 10 分钟」动作卡。
Write a first-ten-minutes card for the loading rack.
