Supermarkets, pharmacies, home improvement, and department stores expose their customers to many potential accident sources such as floors and aisles, which can become unsafe, and display merchandise that can topple or cause tripping. To prevent such accidents from occurring, these establishments should maintain routine scheduled inspections to insure that unsafe conditions are detected and corrected before accidents occur. They must also anticipate that unsafe conditions can develop rapidly during rain and snow days and that product spills, display instabilities and product delivery equipment may be encountered by unsuspecting shoppers.
