Is there a minimum aisle width required where forklifts are used?
There are no minimum aisle widths specified in 29 CFR 1910 for forklift use. The general material handling requirements state that where mechanical handling equipment is used, sufficient clearances for the type and size of the equipment shall be maintained, including sufficient aisle clearances. [See 29 CFR 1910.176(a)] The powered industrial truck rules also require sufficient overhead clearance from pipes, lights, overhead installations, sprinklers, etc. [See 29 CFR 1910.178(m)(8)] Sufficiency is based on the size and maneuverability of the material handling equipment, including specific forklifts.
