The local construction equipment supplier deploys otherwise-idle yellow iron in all the parking lots in preparation for snow season. They haven’t gotten much use this year, which is OK by me.
A Komatsu excavator behind a bank sports some puzzling warning placards:
This one seems to mean you should stay out from underneath the bucket, which makes sense:
But what’s this one mean? You may be crushed, so keep your distance from doors?
Maybe read the manual before / while being backed over?
Even though this stuff has become entirely too abstract for me, it’s just another day in the life for Stickman!

I’m guessing they mean something like “always have an escape strategy”, but you’re right, they aren’t all the “understand in a glance” sort of pictograms.
I made a halfhearted attempt to unearth a Rosetta Stone for placards, but came up empty handed. I’m sure such a thing exists, though.
It’s surely on the OSHA checklist for those mandatory Yellow Iron users safety meetings…
Some of the warnings they put on things are kind of interesting like complete common sense however the fact that they have to put a warning on them about it means that someone has tried it before and discovered first hand what a bad Idea whatever they were doing was.
Aye, but some of those symbols make no sense at all: what does a blank rectangle mean?
There must exist a Rosetta stone that translates those things…
