According to an article entitled “Reducing Slips, Trips and Falls in Stairways” by Wayne Maynard and George Brogmus, “More serious upper and/or lower extremity injuries occur traveling down a stairway than when traveling up a stair way. In stairway decent, the tread depth – or horizontal surface – must be adequate for the ball of the foot to land on the tread without extending over the step below.” There are specific recommendations for riser and tread dimensions to help prevent these injuries from occurring.
The current stair tread and riser recommendations include:
Though the height and depth of the stair tread is crucial during the construction phase to help prevent accidents, the stair tread itself, if not protected, can still be a slippery surface to walk on. As a result, non slip stair treads can be easily installed over existing slippery stairs, making them safe and slip resistant.
Many stair accidents are considered due to poor maintenance, lack of proper attention and use of the stairs. In my opinion, if stair treads are kept clean, wear resistant and contain a non slip surface, these accidents could be significantly reduced, providing users with a safe elevated walking environment.
