6、险辨析与预控4.1SF6开关交接试验前，施工项目部根据该项目作业任务、施工条件，参照《电网建设施工安全基准风险指南》（下简称《指南》）开展针对性安全风险评估工作，形成该任务的风险分析表。4.2按《指南》中与SF6开关交接试验相关联的《电网建设安全施工作业票》（编码：BDYCSY-ZW-15-01/01），结合现场实际情况进行差异化分析，确定风险等级，现场技术员填写安全施工作业票，安全员审核，施工负责人签发。4.3施工负责人核对风险控制措施，并在日站班会上对全体作业人员进行安全交底，接受交底的作业人员负责将安全

7、措施落实到各作业任务和步骤中。4.4安全施工作业票由施工负责人现场持有，工作内容、地点不变时可连续使用10天，超过10天须重新办理作业票，在工作完成后上交项目部保存备查。表4-1作业任务安全基准风险指南序号危害名称风险种类风险等级风险控制措施1试验设备未接地或接地不良设备损坏低风险试验前，应认真检查接地线连接可靠，接地良好2试验人员接线错误设备烧损中等风险在试验前工作人员需熟悉说明书、图纸，按照要求接线，并有工作负责人核查接线正确性3试验区域未设置安全围栏人身伤残中等风险试验区域必须按规定设置安全围栏和标示牌

8、等安全措施，并安排专人进行监护4引接试验电源时触电人身伤亡高风险严格执行电气工作票，落实各项安全措施，加强监护5试验电源不稳定设备损坏中等风险试验前应用仪器测量电源电压，确保符合试验要求6试验设备吊装时安全防护措施不完善设备损坏高风险吊装时工作人员必须持证上岗、专人指挥吊装7气体泄漏污染环境环境污染可接受的风险按照厂家技术说明书操作，正确使用工器具8气体排放人员中毒健康受损低风险试验人员避开放气阀9
