Final answer:
The recommended aisle width between file units is at least 36 inches for traditional cabinets, and may be increased to 44 inches for ADA compliance.
Step-by-step explanation:
The recommended number of inches for aisles between file units depends largely on the type of filing system and the anticipated levels of accessibility and traffic. Generally, for traditional file cabinets, aisles should be at least 36 inches wide to allow for the drawers to be fully extended and to provide enough space for individuals to pass by comfortably.
In environments that must comply with the Americans with Disabilities Act (ADA), the minimum aisle width may be increased to 44 inches to accommodate individuals using wheelchairs. It's always best to consult specific guidelines and codes relevant to your location and situation for precise requirements.
When setting up file units, it is recommended to have a minimum aisle width of 36 inches for single-sided shelves and 42 inches for double-sided shelves. These dimensions provide enough space for individuals to comfortably navigate between the file units without feeling cramped or restricted.
