Safety Cups - yellow and black and danger-free - but what are they for?

Today is officially a Good Day, as I was lucky enough to get the 'Safety Cup' from the Which? office drinks machine.

It's a bright yellow cup, with 'Safety Cup' handily written across its middle. Em and I both think that it could do with a bit of embellishment, however - perhaps a black and yellow diagonal stripe pattern around the rim to draw attention to how safe the cardboard edge is...

BUT, wait. What is the safety cup for? Is it like in Formula 1, where they bring on the safety car when things get dangerous? What does it mean in the context of office drinks machines. Should we drink extra slow, and avoid skidding on wet patches on the floor?
