I am very qualified and never disqualified in one 65 retail cases in four years. I have served as an expert retail witness in Supermarket cases for the plaintiff involving Slip and Fall, Display design malfunctions and product display presentation. With two degrees in Architecture, and over 35 years of practical Store Design including supermarket venues, I am able to comment and evaluate the very items you suggest could not be per Industry Standard and manufacturing best practice. In addition, I currently serve as one of twelve store planners serving the American Display Industry Organization on the Creative Design Committee. It sounds like an afterthought as most reputable refrigerated case manufacturers have a proven safe way to protect the lower end corner of a case. I do not understand why the guard would “stand-off” from the unit, unless there was some glass that could be hit by a shopping cart. Otherwise, there is no reason to have what sounds like a makeshift hazardous to be utilized. Lastly, it is a common practice to “break” all metal edges to eliminate metal spurs, or razor sharp edges to interact with a customer. I have designed over 50 million dollars of displays and oversaw the installation and manufacturing stages and can speak to my experience to address similar conditions which I have encountered over my career of hands-on design, supervision of installations and manufacturing.
