Description
You can't stand over every worker to check the right gear's on, but you can make the requirement impossible to miss. That's what the "Blind Intersection Sound Horn" sign is for.
It's a small, unremarkable detail on a normal day, and exactly the kind of thing people look for when they're checking a site is doing things properly.
The kind of sign you put up once and don't think about again, which is exactly the point.
