I will have a soon-to-be published book on foodservice facility planning and design that addresses ergonomics. The manuscript is at the publisher now. The book will be released around Christmas, I believe.
Does the book cover the weight of the french fry baskets and the usual method of lifting and dumping them? That can be hard on the elbows and forearms. What about the inaccessibility of the milkshake machines that usually are loaded from the top? This usually requires an above-shoulder reach, or using a stepstool.
