The first sign is a special case. It says Slow - Workmen crossing the street. It's thus not exactly a warning sign that people are working on the road. The warning is placed very close to the possible impact zone.
I wonder why they did so. Costa Rica is a small country and perhaps there wasn't enough
room to plant the sign any further away ? But Belgium is even smaller
and warning signs there are kept at a decent 25m.
Anyway, fifteen meters is near and drivers in Costa Rica are supposedly very alert.
They have to because the drawing shows that the workers aren't light-footed enough
to quickly clear the road.
The second find is a hybrid: the diamond shape is typical for
the Americas but the man is taken from the Mediterranean Workforce: a group of related designs often found in countries around the ditto Sea.
