Fall Protection Requirements
When OSHA passed the new Walking and Working Surfaces Standard for the General Industry in 2016 they also updated the fall protection requirements in the Regulations Standard 1910 Subpart I. Due to the fact that Subpart I has been updated, OSHA also updated the fall protection requirements in the Electric Power Generation, Transmission and Distribution Standard for the General Industry (Standard 1910.269).
The new requirements now reference 1910 Subpart I rather than the previously referenced 1926 Subpart M. The requirements in the new Subpart I can be found here: https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=1291.
