今日目标 | Learning objectives
区分直接原因与根本原因，按结构化流程调查事故与未遂事件，并提出可验证的纠正措施。
Distinguish immediate from root causes, investigate incidents and near misses systematically, and define corrective actions whose effectiveness can be verified.
核心概念与术语 | Key concepts & terms
系统收集事实、分析促成因素并制定预防措施；目标是预防再次发生，不是寻找替罪者。
A systematic process to gather facts, analyze contributing factors and prevent recurrence—not to find someone to blame.
最接近事件的行为或条件，例如湿滑地面、缺少隔离。
The action or condition closest to the event, such as a wet floor or missing barricade.
让危险持续或防护失效的系统缺陷，如清洁计划不清、巡检失效、责任或资源不足；根因可能不止一个。
Underlying system weaknesses that allowed hazards or failed controls to persist; multiple root causes may exist.
针对已识别原因采取措施，并验证有效性；不应只写“加强教育、注意安全”。
An action addressing identified causes and checked for effectiveness—not merely “remind workers to be careful.”
调查流程 | Investigation workflow
- 救助并控制现场 / Care for people and make the scene safe.
- 保全证据：照片、设备状态、现场条件、记录和目击者陈述。/ Preserve photos, equipment state, conditions, records and witness accounts.
- 建立时间线并分析原因：区分事实、推断与未知；追问“为什么”。/ Build a timeline, separate facts from assumptions, and ask why.
- 制定措施：明确负责人、期限、资源和完成标准。/ Define owner, due date, resources and completion criteria.
- 验证并分享经验：确认风险降低，更新程序并反馈。/ Verify risk reduction, update procedures and share lessons.
调查适当的伤害事件和未遂事件；严重事件按适用法规与组织程序及时报告。/ Investigate appropriate injuries and near misses; report serious events as required by applicable rules and procedures.
现场场景 | Field scenario
工人在材料通道积水处滑倒。主管记录“工人注意力不集中”，要求重新培训。作为 HSE 负责人，你如何推进调查？
A worker slips on standing water in an access route. The supervisor records “inattention” and orders refresher training. What should the HSE lead do?
- 先救助、隔离湿滑区域并保全证据。/ Care for the worker, isolate the hazard and preserve evidence.
- 查明积水来源、排水和清洁安排、巡检频率、报告记录与责任分工。/ Check water source, drainage, housekeeping, inspections, reports and responsibilities.
- 采取工程/现场控制（修复排水、改善地面、防止积水），辅以巡检与培训；指定负责人和期限。/ Apply engineering/site controls, supported by inspections and training, with owners and deadlines.
- 复查现场并跟踪类似事件，验证措施有效。/ Reinspect and track similar events to verify effectiveness.
培训可作补充，但不能替代对危险源和系统缺陷的处理。/ Training may supplement controls, but cannot replace fixing the hazard and system failures.
指标计算 | Rate calculation
TCIR = 可记录伤病病例数 × 200,000 ÷ 总工时TCIR = Recordable injury/illness cases × 200,000 ÷ hours worked
例 / Example: 3 起符合 OSHA 记录标准的病例，全年总工时 300,000 小时。/ 3 recordable cases and 300,000 hours worked.
(3 × 200,000) ÷ 300,000 = 2.0
200,000 小时代表 100 名全职员工按每周 40 小时、每年 50 周计算的基准。病例须按适用 OSHA 记录规则判定；其他司法辖区口径可能不同。发生率不能单独代表安全绩效。/ The 200,000-hour base represents 100 full-time workers at 40 hours/week for 50 weeks/year. Classify cases under applicable OSHA recordkeeping rules; other jurisdictions may differ. A rate alone does not measure overall safety performance.
测验 | Knowledge check
巡检多次记录地面积水但一直未整改。最有价值的下一步是什么？/ Water accumulation was repeatedly noted in inspections but never corrected. What is the most valuable next step?
自编练习题，不是 BCSP 官方真题。/ Original practice question, not an official BCSP exam item.
巩固练习 | Short-answer review
1. 为什么“工人粗心”不足以作为完整根因？/ Why is “worker carelessness” not a complete root-cause analysis?
2. 写出一项可验证的纠正措施，并说明如何验证。/ Give a verifiable corrective action and how to verify it.
