Not inspecting. Using step ladder as a straight ladder. Using top step or top of step ladder. Not extending extension ladder 3' above roof or leading edge.

I performed a lot of audits when I was in graduate school. I saw systemically poor ladder etiquette whether it was storage (they were everywhere!), use (3' above edge, type of ladder; top step; three points of contact), or simply not replacing ladders appropriately (old wooden ones that were broken; ladders without labels). Happy to not be in that environment anymore...

Extension ladders or using the 4 to 1 ratio when extending it out for use. Also using the wrong ladder for the job. You have some people working at heights of 7 or 8 ft high using a 6 foot ladder

Sorry Not using the 4 to 1 ratio.

Not securing extension ladders, extension ladders not extending 3' past the landing, and a large gap next to the extension ladder that creates a fall hazard. If an extension ladder landing is open, an access coral must be installed around the opening.

Leaning ladder against the wall and climbing not opened.

New to the platform! I'd like to address OSHA's requirement passed November 19th, 2018 requiring fall arrest or ladder safety systems on all new ladders. I still to this day see countless fabrication and construction companies not paying any attention to this and fabricating or ordering barrel cages for sites. Companies must abide and start using fall arrest/ladder safety systems.

In construction. Name the trade and I'll give you the violation. Electricians bring the shortest ladder causing them to use top and top step. Plumbers lean step ladders against the wall. Mechanical guys straddle ladders.
