4 安全风险辨析与预控
4.1 导、地线展放作业前,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》中与导、地线展放作业相关联的《电网建设安全施工作业票》(编码:PWJX-03-01/01), 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。
