On low-slope roofs, OSHA puts the warning line minimum setback at 6 feet from the edge; I still see crews stringing them 3–4 feet when the crane is moving material. If you catch that during a 7 a.m. site walk, what’s your go-to fix and how are you documenting the correction to prevent a repeat?
7 a.m., pause crane; reset to ‘6 feet,’ snap chalk line; photo in daily; repeat offenders get toolbox talk?
I’d bump it to 10 ft when the crane’s moving — OSHA 1926.502(f)(1)(i) says “warning lines…not less than 10 ft” with mechanical equipment (1926.502 - Fall protection systems criteria and practices. | Occupational Safety and Health Administration). My fix: pre-painted 6’ and 10’ lines and a red-tagged “lift” warning-line kit we swap in under a minute, then photo + note the change in the daily — like giving the crane a wider lane. @OP, do you want a simple JHA sticker that reads “10 ft when mech’s moving” to kill the repeats?
I snap a dated chalk line at ‘6 feet’ and photo-log; add a spotter; you log it in the JHA?
