12.1.1.2-7 Maneuvering Space

Adequate space should be allowed between the back (user’s position) of workstations, desks, and consoles and any surface or fixed object behind the user for the user to get into and out of a chair freely or to turn in the chair to view the equipment behind.

Additional Information: A minimum separation of 92 cm (36 in.) from the back of any desk to any opposing surface is suggested (see Figure 12.2). A greater separation is preferable. Lateral space for a seated user should be no less than 76 cm (30 in.); greater latitude is preferable. Placement and spacing of equipment depends on control room configuration, staffing, and other design features. Thus, guidelines are stated in terms of minimum spacing for common equipment arrangements and use. Equipment maintenance and testing have not been considered and may require larger clearances than the minimums suggested.0700
