35.73 -危险能量控制标准(包括闭锁/标签)

A. 一般. Energy sources within the campus environment must be identified and properly controlled. University employees required to service or maintain machinery and equipment are subject to serious injury if such energy sources are not properly controlled. Examples of energy sources subject to unexpected release during maintenance activities include, 但不限于, 电, 热, 液压, 气动, 蒸汽, 机械能.

A-1. 监管要求. Hazardous energy control standards are mandated by the Idaho Administrative 程序 Act 17.10.01.006.02; and are found in Idaho 一般 安全 and 健康 Standard 150.12; Title 29, Code of Federal Regulations, Part 1910.147; and the National Fire Protection Agency Standard 70E, Chapter 4. These standards require that written lockout/tagout programs be established for service and/or maintenance work on machines and equipment subject to unexpected release of hazardous energy sources.

B. 过程. The following procedures and/or work requirements apply to all university employees or students that service and/or maintain machines or equipment subject to unexpected release of hazardous energy sources.

B-1. 责任. These standards assign specific responsibilities to university employees and/or students. 具体地说,

i)主管必须:

a)实施书面的危险能源控制程序.

b) Ensure that employees or students are properly trained regarding implementation of the hazardous energy control program. Such training must occur prior to de-energizing or servicing affected machines or equipment.

c) Supervise and enforce program implementation and periodically inspect and evaluate equipment and machinery subject to such energy control programs.

d) Ensure non-university personnel authorized to service or maintain university machinery or equipment are aware of the university’s hazardous energy control program; these personnel should be informed of locks, 标签 or other lockout/tagout equipment they might encounter during their servicing efforts. 类似的, non-university personnel are required to advise university supervisory personnel of the lockout/tagout procedures and equipment they intend to use so affected university personnel can be informed as required.

ii)大学员工和学生必须:

a) Strictly comply with procedures contained in their respective department’s hazardous energy control program.

三)环境卫生 & 安全人员可以:

协助各部门制定书面的危险能源控制方案.

b) Assist supervisors in providing appropriate hazardous energy control program training for employees or students.

c) Provide supervisors with technical assistance and information regarding appropriate procurement of energy control related machinery or equipment.

C. 程序.

C-1. 一般要求. The following basic requirements apply to all machinery or equipment subject to hazardous energy control programs.

i) All persons who might be exposed to hazardous energy sources must be trained in their respective department’s hazardous energy control program. Training must cover all aspects of energy exposures and the appropriate procedures and equipment use to eliminate related hazards. Employee responsibility for complying with established procedures is mandatory.

ii) All employees performing maintenance or servicing activities on equipment or machinery subject to potential hazardous energy release must be provided and use appropriate lockout/tagout devises 以及类似的设备.

iii)用于危险能量控制程序的设备, 比如锁, 标签, 标签, 以及类似的设备, 必须标准化, 很容易被识别出来, 而且只用于这个目的. [注:标签警告必须注明“请勿移除”.]

iv) Individual employees are required to place their own personal lockout/tagout device on appropriate energy isolating devices. Approved multiple hasps, lockboxes, 以及类似的设备 may be used when necessary.

v)一次锁定, 贴上标签或类似的装置, 只有施咒者才能将其除去, 或者在他/她的监督下.

vi)上述参考文献v). Departmental hazardous energy control programs should include specific procedures for removal of 标签 or locks of individuals absent from the workplace. Such tag or lock removal must be documented and communicated to the original owning maintenance or service person(s).

C-2. 一般程序. The following sequential procedures should be documented into each departmental hazardous energy control program:

i)锁定和/或标示危险能源;

Notify all affected employees of the appropriate lockout/tagout system being utilized.

按正常程序关闭运行中的机器或设备

隔离机器或设备的能源(通过开关，阀门等)

Lockout and tagout the energy isolating devices with lock(s) and tag(s) as required.

储存能量(e).g., 电力电容器, 压缩弹簧, 高架机械部件, 液压, 空气, 气体, 蒸汽, 水压)必须通过重新定位来消散或抑制, 消隐, 阻塞, 或者排出多余的压力.

有资格的人员使用适当的测试设备, 验证电路, 机器或设备实际上是断电而不能运行. Ensure operating control(s) are returned to the “off” position after testing is complete.

ii)服务连续性. If it is determined that continuing service is essential or shutting down a system is impractical, 可以使用经批准的替代方法来控制危险能量, 前提是他们能提供同等程度的人员保护.

iii)恢复危险能源:

Once machinery or equipment has been properly rep空气ed and is ready to be reactivated, lockout/tagout devices may be removed and energy may be restored only by authorized personnel following proper procedures.
