So I just completed making a sheet of signs that would make sense in a Petro/Chemical Plant. I'll print these out tomorrow and mount them in strategic locations. I added the text in the "number of accident free day" sign. There are all readily available in a Google search. I look at IMAGES and click on the one I like to make it larger then make a screen print. I crop the image in a photo reviewer software. I use a Mac so this is pretty easy to do. I use PVA to make the back sticky and put them on thin styrene. I'll print them out on Glossy hi-res photo paper. It easier than making decals out of them.
