场景走一遍 | Walk the scenario

物流仓库月度数据：①夜班拣货差错率比白班高 2.4 倍，其中「连上 6 晚以上」的员工占差错的 70%；②手部不适投诉集中在使用角磨机的 5 名打包工（日接触约 2.5 h）；③排班表显示：当前是逆时针轮转（夜→中→早），且夜班常连 6–7 晚。

A warehouse sees night-shift picking errors 2.4 times the day rate, with staff on six-plus straight nights behind 70 percent of them; hand complaints cluster in five packers running angle grinders about 2.5 hours daily; and the roster rotates backward — night to swing to morning — with six-to-seven-night strings.

1. 第一步：改排班结构——逆时针改顺时针（早→中→夜）；夜班连值上限设 4 晚并在第 3 晚后插入完整休假日；班间休息保证 ≥ 11 h；把「连值=差错」的数据反馈给排班负责人，用差错率跟踪验证修正效果 — Step 1 — restructure the roster: flip to forward rotation, cap nights at four with a full rest day after the third, guarantee at least eleven hours between shifts, and hand the scheduler the error data to verify the fix by trend
2. 第二步：振动双管——5 名打包工按 A(8) 折算：2.5 h 触发时间的角磨机很可能超行动值；措施：换低振动机型+打磨任务轮换（与不用磨机的任务对调，等效日暴露减半）+防振手套作为辅助+申报制度（出现白指即报即评） — Step 2 — the vibration track: 2.5 hours of grinding likely breaches the action value once converted to A(8); swap to low-vibration models, rotate grinding against non-grinding tasks to halve daily exposure, issue anti-vibration gloves as support, and stand up a white-finger reporting route
3. 第三步：制度固化与验证——把「顺时针+≤4 连夜+11 h 班间」写进排班 SOP；夜班差错率、HAVS 申报数进月度安全指标；3 个月后复测：差错率是否回落至白班 1.5 倍以内、手部投诉是否清零——没有回落则查照明与任务设计 — Step 3 — institutionalize and verify: write the rules into the roster SOP; track night error rate and HAVS reports monthly; re-check in three months whether errors fall under 1.5 times day rate and hand complaints clear — if not, look at lighting and task design

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.
