Subject: 29 CFR 1910.22(b)(2), Markings For Aisles and Passageways

1. Purpose

To provide an interpretation of "appropriately marked" as applies to permanent aisles and passageways where there are dirt floors or floors having continuous concentrations of sand or fine dusts.

2. Documentation Affected


3. Background

a. In some instances, 29 CFR.1910.22(b)(2) has been narrowly interpreted to mean that aisles and passageways must be marked by painted floors lines.
b. The intent of "appropriately marked" is not to restrict the markings to one method only. It would be impractical to paint lines on dirt floors or floors that have continuous concentrations of sand or other dusts. These conditions may exist in such industries as foundries, scrap salvage operations or motor winding facilities.

4. Action

Painted lines remain the most feasible method of marking, where practical, since they may last several years without maintenance or repainting. Other appropriate methods such as marking pillars, powder stripping, flags, traffic cones or barrels are acceptable, when the training programs for vehicle operators and employees include the recognition of such markings.

OSHA Instruction OCT 30, 1978 STD 1-1.4

5. Effective Date

This directive is effective immediately upon receipt and will remain in effect until canceled or superseded.
