Section 6.25. Plasterers’ and decorators’ inside scaffolds

(a) Trestle. The use of ladders which lean against the wall, barrels, boxes or other similar unstable objects as support for planking is prohibited. Platform planks shall be at least two inches in thickness and shall not have a span of more than ten feet. Where or trestle ladders are used to support planking they shall conform to the requirements set forth in Chapter 21 (relating to ladders). The ladder shall be spread before placing the planking on it. The trestle or horses shall not be more than two tiers high and shall be built as specified in § 6.24 (relating to horse scaffolds).

(b) Larger scaffolds. Where it is necessary to use larger scaffolds for inside work, only such scaffolds as have been approved for such work shall be used, or they shall be constructed according to the specifications contained in § 6.13 (relating to independent pole scaffolds). Where it is necessary to build the scaffold to an unusual height, the poles shall be of proportionately heavier material. Since plasterers’ and decorators’ inside scaffolds are frequently built not only lengthwise but also deep, the diagonal cross bracing shall, in such cases, be provided in both directions. Provisions shall be made for equipping the scaffolds with guardrails and toeboards on the outside edges of the various platforms.

(c) Short cut passageways. Short cut connection between different parts of the same scaffold by means of unprotected planks is prohibited. Where such connection is made it shall be by a properly constructed and substantially supported passageway or temporary platform, and such passageway or platform shall be equipped with guardrails.

(d) Protection. Protection shall be afforded as set forth in § 6.32 of this Title (relating to protection).
