场景走一遍 | Walk the scenario

屋面空调机组换滤网。屋面到下层地面 30 ft；周边无护栏；滤网位在设备侧面，无法在地面完成；屋面有核定的脊部锚点，位于作业点正上方。工人身高 6 ft，库存有 6 ft 挂绳 + 缓冲包、4 ft 挂绳 + 缓冲包、定长 2.5 ft 限制绳（该锚点可接限制绳）。

Filter change on a rooftop AC unit. Roof-to-grade is 30 ft; no guardrails; the filter is on the side of the unit and cannot be done from ground level; a qualified ridge anchor sits directly above the work point. The worker is 6 ft tall. Stock: 6 ft shock-absorbing lanyard, 4 ft shock-absorbing lanyard, and a 2.5 ft fixed-length restraint line the anchor can accept.

1. 第一步：按控制层级扫一遍——能不能不上屋面（不能）；有没有护栏（没有）；能不能用限制（2.5 ft 绳到不了边缘的话，能） — Step 1 — sweep the hierarchy: eliminate (no); guardrail (absent); restraint (yes, if 2.5 ft keeps the worker off the edge)
2. 第二步：若必须靠近边缘换滤网，限制不可行，进入制动——用 4 ft 挂绳代替 6 ft：自由落体更短，净空需求更小 — Step 2 — if the filter forces the edge, restraint fails and arrest applies: the 4 ft lanyard beats the 6 ft one — shorter free fall, smaller clearance demand
3. 第三步：核对净空——4 ft 挂绳方案约 16.5 ft 需求 < 30 ft 落差 ✓；同时定救援：谁、多久、用什么解除悬挂 — Step 3 — verify clearance (~16.5 ft demand < 30 ft drop ✓) and set the rescue: who, how fast, how the suspension is relieved

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「层级 + 数字」合起来选方案：不是挑最长最结实的装备。
Tests choosing by hierarchy plus numbers — not picking the longest, sturdiest gear.

按上述三步，最优配置是哪一项？

Following the three steps, which configuration is best?

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. 把这个场景改写成「锚点在作业点侧面 10 ft」，重新走三步，指出新增的风险与措施。
Rewrite the scenario with the anchor 10 ft to the side, redo the three steps, and name the new risk and fix.

2. 为这个作业写两行救援安排：谁在屋面、什么时限。
Write two lines of rescue arrangement for this job: who is on the roof, within what time.
