If you're designing a font not just for legibility, but primarily for safety, then it seems extremely important that each glyph is uniquely distinguishable from other glyphs. Although this font has different characters for 1/I/l, at a quick glance an uppercase i could still be confused with a pipe (|), and 0 (zero) and O (capital o).[1] I'm sure there are more. So from that standpoint, this font fails for me for legibility/safety.
Also a nitpick, but assuming Chrome is using 60pt B612 font for the title (../fonts/B612-Regular.woff), the "B/6/1" glyphs are hideously formed (that "1" puke) and make me doubt the rest of the character set.
