Over the past several years, much has been done to address deck and stair safety issues, but we still have a long way to go. One glaring example of the failure in deck and stair safety protocol is the industry standard of permitting "hot dipped galvanized" anchors, screws, hangers and other hardware to be in direct contact with ACQ, pressure treated wood. The galvanic corrosion created between the high copper content of the wood and the galvanizing is so severe that the normal industry standard of G90 galvanizing will corrode in as little as 12 months and G185, such as Z-Max® can be gone in 24 months. The industry (including code officials) has adopted G185 as a fall back position with no engineering testing available to substantiate the validity or longevity of this adoption...this is a "knee jerk" reaction and is an accident waiting to happen. Without a barrier between the pressure treated wood and galvanized hardware, serious corrosion is inevitable.
The stairs has long been a source of potential danger for humans and those that are mobility challenged, like sufferers of osteoarthritis, are at increased risk. To help reduce this risk there are several things that can be done by the stair user. One of the most important things to remember is that it is important to pay attention when you are climbing up and down the stairs Stairs can come in different shapes and sizes, so it is important to pay attention to the width and depth of the steps. It has been shown that a major factor in many stair accidents is as a result of the person on the stairs being distracted by environmental factors. It is important to maintain a well lit stairway and to pay attention as you ascend or descend the stairs.
