§8366. Interior Staging and Scaffolding.

(a) Staging used on shells and bulkheads shall be supported by metal hangers, or by wooden uprights of a dimension used for uprights of outside staging, as specified in Section 8362(a), or by stock which will give the equivalent support. Where wire rope is used for hangers, it shall not be less than three-eighths-inch diameter and not less than three clips, or other accepted methods of end attachments shall be used to secure the loop.

(b) All interior staging 5 feet or more high, except in engine and boiler rooms when they interfere with the installation of machinery, shall be equipped with a standard guardrail on the open side and ends. The guardrail shall be in the same vertical plane as the edge of the platform which it protects, and shall be attached to its supports or mountings on the platform side. The rail shall be of 2 x 4-inch lumber, or stock of equivalent strength.

NOTE: Three-eighths-inch wire rope, if kept taut at all times is considered equivalent; fibre line is not.

(c) No interior staging shall be suspended by fiber rope except as otherwise provided in painters' staging.

(d) All hanger rods used as supports for staging shall be not less than three-fourths-inch round steel, or if made of other shaped steel, they shall be of equivalent strength. Structural reinforcing steel shall not be used for hangers.

(e) Hangers shall be so arranged that the area supported by one hanger will not exceed 100 square feet of staging.

(f) Permanent suspended staging shall be supported by beam clamps, wire rope, or extension rods from the overhead deck beams.

(g) Safe access shall be provided to all staging levels.
