Keeping employees safe is a cornerstone of most industrial safety policies. Often, facility safety personnel are unaware of what the requirements are for electrical systems, so they treat those policies as special. Many forest product industry facilities have standards related to their electrical distribution systems and testing requirements. Most insurance carriers require protective devices to be periodically tested. The National Fire Protection Association (NFPA) 70E standard requires electrical systems to be maintained and, by extension, so does the U.S. Occupational Safety and Health Administration. How does one know if the systems in place are adequate? How should systems be assessed, and what is the basis for the assessment? Given that resources are limited, how can a representative portion of a system be evaluated to get an idea of how it is overall? This article explores one company's approach based on a recent, corporatewide electrical safety and power system assessment.

评估电气系统的健康状况

确保员工安全是大多数工业安全政策的基石。通常，设施安全人员不知道电气系统的要求是什么，因此他们将这些政策视为特殊政策。许多林产品工业设施都有与其配电系统和测试要求相关的标准。大多数保险公司都要求定期测试保护装置。美国国家消防协会 (NFPA) 70E 标准要求维护电气系统，美国职业安全与健康管理局也要求维护。如何知道现有的系统是否足够？应该如何评估系统，评估的基础是什么？鉴于资源有限，如何评估系统的代表性部分以了解其整体情况？本文基于最近的全公司电气安全和电力系统评估，探讨了一家公司的方法。
