本课只做一件事：把「受限空间与动火作业」的 6 个高频英文术语从「眼熟」变成「能用」：定义、易混、例句。

Turn the six high-frequency terms of Confined Space & Hot Work from familiar to usable: definition, look-alike, example.

本课不涉及：不扩到别的板块的术语，也不考题型技巧。
Not covered here: No terms from other blocks, no question-technique work.

本课目标 | Learning objectives

  1. 为每个术语说出定义，而不是只给中文对应词
  2. 指出每一对易混词差在哪一个限定条件上
  3. 把每个术语放进一句真实的现场英文里

  • Define each term rather than translate it
  • Point to the exact qualifier that separates each look-alike pair
  • Put each term into one real site sentence

    术语详解 | Glossary in depth

    Permit-Required Confined Space / 许可空间
    具备受限空间特征，且含或有潜在大气危险、淹埋、内陷等可能致人失能的危险，进入须书面许可。
    A confined space with actual or potential atmospheric, engulfment, entrapment or other serious hazards; entry requires a written permit.
    易混 / Easily confused：与受限空间不同：受限空间是物理定义，许可空间是叠加危险判定后的管理等级。
    Not every confined space: permit-required is a hazard-based management level on top of the physical definition.
    例句 / In a sentence：The tank is listed as a permit-required confined space. / 该储罐被列为许可空间。
    Hazardous Atmosphere / 危险大气
    缺氧或富氧、可燃气体超标、有毒气体超过 OEL 的大气状态，是受限空间死亡的首因。
    An atmosphere deficient or enriched in oxygen, with flammable gas above limits or toxics above the OEL — the leading cause of confined-space deaths.
    易混 / Easily confused：与「闻到怪味」不同：H₂S 会在高浓度麻痹嗅觉，无味不等于无害。
    Not 'it smells fine': high H₂S deadens the sense of smell; odourless is not safe.
    例句 / In a sentence：A hazardous atmosphere was detected at the bottom layer. / 底层检出危险大气。
    Engulfment / 淹埋
    被液体或可流动固体（砂、粮、粉料）包裹并窒息，是许可空间的第二类致命危险。
    Being buried by liquid or flowable solid (sand, grain, powder) leading to asphyxiation — the second fatal hazard class.
    易混 / Easily confused：与 drowning 不同：淹埋不限于液体，粉体同样会把人完全封住。
    Not just drowning: dry solids bury and seal a person just as completely.
    例句 / In a sentence：Bridging grain caused the engulfment hazard. / 结拱的粮堆带来淹埋危险。
    Entry Attendant / 监护人
    守在入口外的人员：记录进入者、保持通讯、监视环境、阻止无关人员靠近，绝不进入救援、绝不离岗。
    The person outside the opening: counts entrants, keeps contact, monitors conditions, keeps others away — never enters, never leaves.
    易混 / Easily confused：与「帮手」不同：监护人一人一名多口空间时也只承担监护职责，职责不可与进入者兼任。
    Not an extra pair of hands: the attendant's duties cannot be combined with entry.
    例句 / In a sentence：The attendant called the evacuation on the first alarm. / 第一次报警监护人就下令撤出。
    Non-entry Rescue / 非进入式救援
    用撤离绳、绞盘、三脚架从外部把进入者撤出，不需要任何人进入空间。
    Retrieving the entrant from outside using a retrieval line, winch and tripod — nobody enters the space.
    易混 / Easily confused：与专业进入救援不同：非进入式由监护人即可执行，是首选；进入式只属于受训救援队。
    Not entry rescue: non-entry can be done by the attendant and is the first choice; entry rescue belongs to trained teams.
    例句 / In a sentence：Non-entry rescue was written into the permit. / 许可上写明了非进入式救援。
    Fire Watch / 火种监护
    动火期间与结束后 30 分钟内持灭火器监视作业区的人员，有权叫停作业。
    The person with an extinguisher watching the hot-work area during the job and 30 minutes after, empowered to stop work.
    易混 / Easily confused：与「保安巡逻」不同：火种监护是专人专岗、不承担其他任务。
    Not general patrol duty: a fire watch is dedicated and does nothing else.
    例句 / In a sentence：The fire watch stayed 30 minutes after welding. / 焊接结束后火种监护又守了 30 分钟。

    情景自测 | Scenario check

    本课理解Lesson comprehension

    这道题考什么：考监护人职责的不可让渡性：这是受限空间题最常见的考点。
    Tests that the attendant's role cannot be delegated — the block's most-tested point.

    监护人看到作业者在井内突然倒下，同时气体检测仪报警。他应先做什么？

    The attendant sees the entrant collapse inside as the gas monitor alarms. What comes first?

    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. 把监护人「三个绝不」写出来，并各配一句现场理由。
    Write the attendant's three nevers, each with one site reason.
