本课只做一件事：拿「承包商与多雇主现场」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 Contractors & Multi-employer Sites 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.

场景走一遍 | Walk the scenario

化工厂把储罐内壁清洗发包给 C 公司。C 的工人持厂区通行证进入罐区，罐口无人监护，未办受限空间许可；罐内残留上一批次的溶剂蒸气。化工厂是 host，现场由其生产经理统筹；C 公司的 orientation 只讲了「门禁与禁烟」。

A chemical plant contracts tank-inner-wall cleaning to company C. C's workers enter the tank farm on site passes; no attendant at the opening, no confined-space permit; solvent vapour from the previous batch remains. The plant is host; its production manager runs the site; C's orientation covered only 'badging and no smoking'.

第一步：角色判定——host 是 controlling（也是已知危害的告知责任人）；C 是 exposing（自己的工人）+ 潜在 creating；缺口在告知与许可两条线 — Step 1 — roles: the host is controlling and owns hazard notification; C is exposing (its own crew) and potentially creating; the failures are notification and permits
第二步：立即行动——停工撤人、隔离罐区；确认罐内是否有人滞留，如有按受限空间救援程序处置 — Step 2 — act now: stop work, evacuate and cordon the tank farm; confirm nobody remains inside, and if so run the confined-space rescue protocol
第三步：制度修复——orientation 重做（含受限空间与化学品告知）；现场统一进入许可由 host 归口；C 的作业方案（含监测与救援）纳入合同前置条件 — Step 3 — fix the system: redo orientation to include confined space and chemical notification; unify entry permits under the host; make C's work plan (monitoring and rescue) a contract precondition

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 host 的告知责任与许可归口：两线缺口同时修。
Tests the host's notification duty and permit ownership — fixing both lines.

按上述三步，以下哪一项最准确？

Following the three steps, which statement is most accurate?

A. 全部责任在 C 公司 All responsibility sits with company C B. host 无责任，因为作业是发包的 The host bears no duty because the work was contracted out C. host 未履行告知与许可归口责任，C 未履行受限空间程序；两边都要整改，第一动作是停工撤人 The host failed its notification and permit-ownership duties, C failed the confined-space procedure; both must fix it, and the first action is stop-work and evacuation D. 只需补办许可后继续作业 Just issue the permit and carry on
