Often with safety in scrap yards, the small things are taken for granted. The tactile edge on stairways is one of those things. Adding a slightly raised and well defined edge to the edge of stairs makes all the difference in the world. They are definitely an improvement to outdoor machinery installations, such as scrap metal shredding plants.
A simple scrap yard solution to increase the tactile edge on stairs and footing on inclines is to add small rebar or flat bar as pictured. The profile of both edges is small enough to avoid trips, yet tall enough to provide traction to steel grating or stairs.
Low cost, easy to install, and easy to maintain. Adding them to your machinery installation will enhance worker confidence on stairs and inclines. You need your team on the job, not out with slips and falls.
