1 Note: This document is a sample translation by Nemo Cheung only for reference, no use for commercial purposes allowed. For more details, please visit http://www.nemocheung.com ANNEX The Lockout/Tagout Program is intended to ensure that all personnel are protected from accidental or unexpected activation of mechanical and/or electrical equipment during maintenance, repairing, cleaning, servicing, or adjusting of prime movers, machinery, or equipment. The program outlines the purpose, authorization and practices to be utilized by COMPANY . (COMPANY) personnel and contractors to guard against the unexpected energizing, start-up, or release of stored energy that could cause injury. (If personnel are servicing or performing maintenance tasks that do not expose them to the potential for unexpected release of hazardous energy, these program requirements do not apply) Energy sources include mechanical, electrical, hydraulic, pneumatic, chemical, thermal or other energy. Personnel performing servicing or maintenance activities or operations are covered by lockout/tagout when any of the following conditions occur:  The employee must either remove or bypass machine guard(s) or other safety device(s), resulting in exposure to hazards at the point of operation;  The employee is required to place any part of his/her body in contact with the point of operation of the machine or piece of equipment; or  The employee is required to place any part of his/her body into a danger zone associated with a machine operating cycle. In the above situations, the equipment must be de-energized and locks and tags must be applied to the energy isolation devices. The program does not apply in the following situations:  While servicing or maintaining cord and plug connected electrical equipment. (The hazards must be controlled by unplugging the equipment from the energy source; the plug must be under the exclusive control of the employee performing the service and/or maintenance.)  During hot tap operations that involve transmission and distribution systems for gas, steam, water, or petroleum products when they are performed on pressurized pipelines; when continuity of service is essential, and the shutdown of the system is impractical; and employees are provided with an alternative means of protection. Employees performing minor tool changes or adjustments and/or other minor service activities during normal production operations that are routine, repetitive, and integral to the use of the equipment are not covered by the lockout/tagout program, provided the work is performed using alternative measures that give effective protection. Affected Employee: An employee whose job requires them to operate or use a machine or piece of equipment on which servicing is being performed under lockout or tagout, or whose job requires them to work in an area in which such servicing or maintenance is being performed. Authorized Employee: A person who locks or implements a tagout system procedure on machines or equipment to perform the servicing or maintenance on that machine or equipment. An authorized employee and an affected employee may be the same person when the affected employee's duties also include performing maintenance or service on a machine or piece of equipment that must be locked, or a tagout system implemented. Energy Source: Any source of electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other energy. Lockout: The placement of a lockout device on an energy-isolating device, in accordance with an established procedure, ensuring that the equipment being controlled cannot be operated until the lockout device is removed. PURPOSE DEFINITIONS 2 Note: This document is a sample translation by Nemo Cheung only for reference, no use for commercial purposes allowed. For more details, please visit http://www.nemocheung.com ANNEX Lockout Device: A device that utilizes a positive means, such as a lock, to hold an energy- isolating device in the safe position and prevent the energizing of a machine or piece of equipment. Servicing and/or Maintenance: Workplace activities such as constructing, installing, setting up, adjusting, inspecting, modifying, and maintaining and/or servicing machines or equipment. These activities include operations where the employee may be exposed to the unexpected energization or start-up of the equipment or release of hazardous energy. Tagout: The placement of a tagout device on an energy- isolating device, in accordance with an established procedure, to indicate that the equipment being controlled may not be operated until the tagout device is removed. The established procedure for the application of Lockout/Tagout shall cover the following elements and actions:  Preparation for lockout/tagout  Sequence for lockout or tagout  Restoring machines or equipment to normal operations  Lockout/tagout involving more than one person  Temporary removal of lockout/tagout devices Implementation of the lockout or tagout system shall be performed only by authorized employees. Affected employees shall be notified by the authorized employee of the application and removal of lockout or tagout devices. Notification shall be given before the controls are applied, and after they are removed from the machine or equipment. PREPARATION FOR LOCKOUT/TAGOUT Make a survey to locate and identify all isolating devices to be certain which switch(es), valve(s), or other energy isolating devices apply to the equipment to be locked or tagged out. More than one energy source (electrical, mechanical, stored energy, or others) may be involved. SEQUENCE OF LOCKOUT OR TAGOUT 1. Notify affected personnel that a lockout or tagout system is going to be utilized and the reason therefore. The authorized employee shall know the type and magnitude of energy that the machine or equipment utilizes and shall understand the hazards thereof. 2. If the machine or equipment is operating, shut it down by the normal stopping procedure (depress stop button, shut valve, etc.). 3. Operate the switch, valve, or other energy isolating device(s) so that the equipment is isolated from it energy source(s). Stored energy (such as that in elevated machine members, rotating flywheels, hydraulic systems, and air, gas, steam, or water pressure, etc.) must be dissipated or restrained by methods such as repositioning, blocking, bleeding down, etc. 4. Lockout/Tagout the energy isolating devices with assigned individual lock(s) or tag(s). 5. After ensuring that no personnel are exposed, and as a check to ensure disconnection of the energy sources, operate the push button or other normal operating controls to make certain the equipment will not operate. CAUTION: Return operating control(s) to neutral or off position after the test. 6. The equipment is now locked out or tagged out. RESTORING MACHINES OR EQUIPMENT TO NORMAL OPERATIONS 1. After the servicing and/or maintenance is complete and equipment is ready for normal production operations, check the area around the machine or equipment to ensure that no one is exposed.

After all tools have been removed from the machine or equipment, guards have been reinstalled and employees are in the clear, remove all lockout or tagout devices. Operate the energy isolating devices to restore energy to the machine or equipment. 《挂牌上锁程序》（《程序》）旨在保护对机械设备、电力设备的推动装置、机械装置或设备本 体进行维护、维修、清理、保养或调试的所有人员，避免发生事故或意外情况。本程序概括描述 了程序的目的、审批流程及公司（COMPANY）所有员工及承包商的执行情况，以防止意外激 活、启动或释放储存能量造成伤害。（本程序不适用于无潜在危害能量意外释放的条件下进行保 养维护的情况。） 能量源包括机械、电力、液压、气压、化学、热量及其他能量。 发生以下任何一种情况时，保养维护人员或作业人员都受《程序》的保护：  因作业需要，必须取下机器防护罩或其他安全防护装置、或需要在旁边进行作业而面临危害 的情况；  需要将身体某个部位接触到机器设备的情况；或  身体某个部位可能会处于因机器周期运转而造成危险的区域的情况。 以上情形中的设备必须断开电源，能源隔离装置必须挂牌上锁。 以下情况不适用于本《程序》：  保养维护时未拔掉电力设备电源线和插头；（必须拔掉设备插头，断开能量源，控制危害； 插头只能由保养维护人员控制。）  在带压管道上进行天然气、蒸汽、水或石油产品运输及分配系统的热连接作业时、保养必须 持续进行且设备无法关停时、有多种保护措施对员工进行保护时。 在按日程进行的重复性正常生产作业中，如果员工需要在设备运转的同时更换工具或对设备稍作 调试或保养，并且有多种保护措施对员工进行保护，这种情况不适用于本《程序》。 相关员工：因工作需要，需操作或使用已挂牌上锁且正处于保养状态的机器设备的员工；或需在 保养维护区域进行作业的员工。 授权员工：对需要进行保养维护的机器设备实施挂牌上锁程序的人员。当相关员工的同时包 含在需要挂牌上锁的机器设备上进行保养维护的时候，授权员工及相关员工可能为同一人。 能量源：电力、机械、液压、气压、化学、热量或其他能量中的任何一种。 上锁：按规定流程将上锁装置安装在能源隔离装置上的操作，其目的是为了确保在移除上锁装置 前不允许操作被上锁设备。 上锁装置：一种使用锁具等工具使能源隔离装置处于安全状态并防止机器设备带电的装置。 保养维护：在工作场所进行的一些活动，如：机器设备的建造、安装、装配、调试、检修、改 装、维护和保养；这些活动中的有些作业可能使机器意外通电启动或释放危险能量。 挂牌：按规定流程将挂牌装置安装在能源隔离装置上的操作，其目的是为了提示在移除上锁装置 前不允许操作被上锁设备。 用于实施《程序》的规定流程应包含以下：  挂牌上锁准备工作； 目的 定义 4 Note: This document is a sample translation by Nemo Cheung only for reference, no use for commercial purposes allowed.
