Posted By Ken Taylor I'm sorry to see that you haven't had a response yet. I have come across these things on a number of occasions over the years but am only aware of a few associated minor accidents. The problem tends to be that the stool requires a load acting downward to keep it in place. When a user steps on or off, there is a point at which there is insufficient force to hold the stool in place. This tends not to be a problem if the user steps on or off with a downward force only but, if the user steps on the nosing of the step, the force is applied toward the horizontal and the stool moves away. The answer seems to lie in user training, supervision and fairly slip-resistant flooring. This is not a vindication of kick stools but they do seem to meet a need where other access equipment would not be reasonably practicable.
