OSHA's walking and working surfaces standard (slips, trips, and falls) for general industry regulates most areas where employees may work or travel in the workplace. Walking/working surfaces include ladders, wall and floor openings, aisles, and scaffolds. Much of the standard is geared to design, construction, and installation specifications for the prevention of worker injuries. Other aspects cover procedures and guidelines for safe use of equipment (e.g., scaffolds and portable ladders).
