High Visibility and Arc Ratings for Flame Resistance

High Visibility and Arc Ratings for Flame Resistance

Two standards are needed to specify clothing for high visibility and flame resistance. Most companies in the U.S. choose ANSI 107 (for high visibility) and ASTM F1506 (for flame-resistance clothing complying with NFPA 70E or OSHA 1910.269).

What You Need to Know About Substations

What You Need to Know About Substations

Beyond information peculiar to technical crafts, every person who enters a substation has a common need to understand substation grounding. This includes things to look for that might indicate problems in the station’s grounding system.

Substation grounding plays the primary role in several key aspects of fault clearing, equipment preservation and, most importantly, personnel protection as well as protection of the passing public.
