The Occupational Safety and Health Administration (OSHA) has guidelines for floor markings to improve safety in warehouse operations. They allow aisle markers, for instance, to be set up in a way that best accommodates operations. Floors can be painted or tape can be used to best direct traffic. In areas where painting or tape is not practical, methods such as colored flags and traffic cones are permitted.
The Color Yellow
Aisles are marked in yellow, the color designated by OSHA for caution. Yellow is also used in areas containing a physical hazard that may cause tripping, stumbling or falling, such as a staircase. OSHA rules indicate that aisles must be marked and must be wide enough to provide safe clearance in areas with mechanical equipment, loading docks, doorways and turning areas.
