I remember the Floor was painted a dark green with Yellow squares painted around each tool to show where you were not supposed to stand when the tool was on. Had some gritty stuff in that yellow paint too.
Also, there was that step to open metal fire bucket for all the shop rags. Also, all the windows had that wire mesh in them.
Each workbench had cold metal stools to sit at that would creak so much the teacher would have to wait until everyone stopped moving so he could talk.
