作业安全分析简明指南

1. INTRODUCTION (介绍) Job Safety Analysis (JSA) is a simple structure approach used to assess potential hazards associated with any identified activity and to ensure risks are minimized. JSA applies the standard Hazard Management Process (HMP) of: 作业安全分析

（JSA）是一种常用于评估与作业有关的基本风险分析工具，以确保风险得以有效的控制。JSA 使用下列标准的危害管理过程 （HMP）：

??Identify the potential hazards and Evaluate the Risks

识别潜在危害并评估风险

??Establish controls (to avoid hazards)

制定风险控制措施 （控制消除危害） ??Plan recovery measures (if things do go wrong)

计划恢复措施 （以防出现失误）

This can be applied to any task.

这个过程适用于任何作业任务。 2. Approach 步骤

For larger or more complex tasks, the initial JSA can be carried out as a desktop exercise at the office.

However, a key principle is that the proper JSA is done in the field with people experienced in the activities and with the facilities.

JSA一般在控制房或作业现场进行。对于大型或复杂的任务，初始的JSA 可以作在办公室以桌面练习的形式进行。其关键是JSA 应由熟悉现场作业和设备的、有经验的人员进行作业安全分析。 The following steps are taken: JSA 通常采取下列步骤：

??

Person from group undertaking the task undertakes preparation for the JSA. Breaks the activity into the key steps and records this on the Job Safety Analysis Worksheet (refer to the following worksheet)

实施作业任务的小组成员负责准备JSA。将作业任务分解成几个关键的步骤，并将其记录在作业安全分析表中（参见下表） 。

??

Assemble JSA team (3 or 4 personnel). Need mix of skills.

Recommend: one operational person who knows the area and the process facility, one from the group undertaking the task and a safety professional JSA 小组成员成员(通常3-4人) ，要求有相关的经验。建议：有1位了解作业区域和生产流程设备的操作人员，有1位负责实施作业小组的成员和1位安全专业人员。

??

Each step reviewed for what could go wrong and list the credible hazards. To help this the team can use the hazards checklist developed by professionals for the specific tasks.

审查每一步作业，分析哪一个环节会出现问题并列出相应的危害。JSA 小组可以使用由专业人员针对具体作业任务而制定的 危害检查清单(根据具体作业而制定)。

??

For each hazard the present specified control measures should be identified and assessed for effectiveness.

针对每一个危害，应对现有的控制措施的有效性进行评估。

??

For each hazard the need for further controls should be considered by asking the question “what more could we do to reduce the risk from this identified hazard?”

Sensible additional controls are then added to the worksheet.

Following completion of the review the safety supervisor /coordinator /manager should summarize the special controls identified by the team for that activity on the Job Safety Analysis Worksheet.

This will list the activity hazards, the special control requirements and who has to implement the controls during the task execution. 审查完所有作业步骤后，安全主管或协调员或经理应将所有已识别的控制措施在安全分析工作表中列出，包括：作业危害、控制要求、在作业期间谁负责实施执行等。

??

The safety Supervisor/Coordinator/Manager files the JSA and may add it to the Asset JSA database if it is considered that the activity may be repeated.

安全主管或协调员或经理应将所有JSA 文件存档，如果某项作业任务以后还可能进行，应

考虑建立JSA数据库，以备将来审查时借鉴和使用。

??

The task supervisor has to ensure that the JSA worksheet is included along with the Work Request Form when the Permit to Work is being initiated. 负责该项作业任务的监督应确保在审批该项作业许可证时，作业安全分析表应和作业许可申请单附在一起。

??

The Task supervisor is responsible for a brief to the work party on the job hazards, controls and limitations (pre-job safety meeting) and ensures all controls are implemented as required in JSA worksheet.

作业任务的负责监督负责向所有参与作业的人员介绍作业危害、控制措施和限制（通常通过作业前安全会），确保所有控制措施都按照JSA的要求及时实施。
