2.3 Routine Operations – Operations in areas solely designated for operations

will not require Permit to Work even though critical operations are carried out.

For example a work shop or grit blasting area where hot work is considered

“normal operation” will not require Permit to Work. However these activities

must be covered under other SSPs or special procedure for the area. Any other

work that is not covered under the area’s procedure will require a Permit to Work.

常规作业----这是指那些在专属区域进行的、但不需要取得作业许可证就可以施工的

作业（即使是关键作业）。例如在喷钢砂处理区域，高温作业是“常规操作”，所以就不必

申请作业许可证。但是，在这些区域进行作业时，必须接受其它现场安全规定或适用该区

域的特殊程序的控制。超出区域程序范围的任何作业，必须申请并获得作业许可证方可实

施。
