How slippery is that surface?

If you ever want to look at installing artificial grass onto a surface which might become slippery then the health and safety people have a special device to measure exactly how dangerous it might be.

Your heel is the mostly the first point of contact with the decking and if there is water here then it can form a thin layer underfoot and it is this which causes the falls. To measure this you perform what is called the pendulum test. This mimics a foot striking the surface and can be adapted to show a bafre foot or even one with a shoe.
