本课只做一件事：拿「消防与生命安全基础」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 Fire Protection & Life Safety 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

按三步走完一个场景，并说出每一步的依据
区分「更有效」与「更先做」两类答案
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

周五 17:40，维修班在喷涂车间外的通道做最后一处管托焊接。作业点 3 m 内有敞开的溶剂桶（I 类易燃液体，约 8 加仑）、通风口正对作业点；动火许可上有火种监护，但监护人在 17:30 被临时叫去帮忙卸货。焊接开始 3 分钟后，溶剂桶口蒸气被引燃，形成约 0.5 m 的火苗。

Friday 17:40, maintenance welds a pipe support in the aisle outside a paint shop. Within 3 m: an open solvent drum (Class I, ~8 gallons) and a vent facing the work; the permit lists a fire watch, but at 17:30 the watch was pulled away to help unload. Three minutes into welding, vapour at the drum ignites into a 0.5 m flame.

第一步：识别连锁违规——可燃物未清到 35 ft 外、通风正对作业点、火种监护离岗；三道屏障同时失效 — Step 1 — spot the chain: fuel not cleared beyond 35 ft, vent facing the work, fire watch absent — three barriers down at once
第二步：即时处置——监护立即归位：停焊、用 BC/ABC 干粉从上风向扑打火焰根部、断溶剂气化源（盖桶、关阀）；火焰超过灭火器能力即撤离报警 — Step 2 — act: restore the watch now — stop welding, attack the flame base with BC/ABC dry powder from upwind, cut the vapour source (lid, valve); if beyond extinguisher capacity, evacuate and alarm
第三步：制度复盘——动火许可的「监护人不得离岗」写成硬条款；溶剂桶离场或入柜；通风口动火期间临时转向；把「最后一处活」列为高风险时刻 — Step 3 — review the system: make the watch non-removable a hard permit clause; move the drum or cabinet it; deflect the vent during work; treat 'the last job of the day' as a high-risk moment

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：考屏障叠加失效的处置顺序：先断燃料气化，再灭火剂。
Tests the order when barriers stack-fail: cut the vapour source, then the agent.

按上述三步，起火瞬间的正确处置顺序是？

Following the three steps, what is the correct order at ignition?

A. 先泼水降温，再搬桶 Throw water to cool it, then move the drum B. 停焊 → 干粉扑打火焰根部并盖桶断气化源 → 超出能力即撤离报警 Stop welding → hit the flame base with dry powder while capping the drum to cut the vapour → evacuate and alarm once it exceeds your capability C. 把桶踢远再继续焊完 Kick the drum away and finish the weld D. 等人回来再处理 Wait for someone to come back
