Stacks [8.5]
Elements fixed to stacks, such as ladders, cannot reduce the minimum passage width nor should signs or other elements between 27 to 80 inches above the floor project more than 4 inches into aisles. Recommendation: Consider accessible circulation around stacks so that people using wheelchairs need not backup for long distances. T-shaped turning space will provide space for wheelchair maneuvering.
Recommendation: Dimensions for turns around obstructions in 4.3.3 (ADAAG Figure 7) provide minimum space for maneuvering around stacks where a cross aisle at the end of stacks is not provided.
