BS EN 61478:2001 PDF Download

The BS EN 61478:2001 standard is applicable to ladders that are made of synthetic material and designed for use in live working on electrical installations at high voltages. These ladders can be fully insulating spliced or hook ladders, with extension capabilities or a combination of insulating and conductive sections.

The standard specifically applies to ladders used in a.c. electrical installations at 1,000 V and above, as well as d.c. electrical installations at 1,500 V and above. The purpose of these ladders is to provide access to overhead line structures and to facilitate live working, which may involve activities like using hot sticks, working barehanded, or a combination of both.
