Wallpaper Description:
Do you Know what the Biohazard sign symbolize ? Nothing Muha ha ha .....Here its history ..

Symbol Making

Charles Baldwin, a retired environmental-health engineer, explains his role in developing the biohazard symbol, which is now showing up everywhere.

I was working with the Dow Chemical company at the time, in 1966, developing containment systems for the Cancer Institute at the National Institutes of Health. And it became obvious to us that there were a lot of different so-called warning symbols in the various laboratories that we visited, but there was no standardization. We saw a need for this kind of a symbol and proceeded to develop some symbols with the help of the Dow marketing people -- the package-design department, I think it was called. The only parameters that I set down for them to noodle through were, it had to be unique and something that would be striking enough that it would be remembered. We wanted something that was memorable but meaningless, so we could educate people as to what it means. New York Times 2001
