23-2.3 Structural steel assembly.
(a) Placing of structural members.
(1) During the final placing of structural steel members, loads shall not be released from hoisting ropes until such members are securely fastened in place. Structural steel members shall not be forced into place by hoisting machines while any person is so located that he may be injured thereby.
(2) Open web steel joists that are hoisted singly shall be transferred from their place of storage directly to their permanent location and secured against dislodgment. Such a load shall not be released from the hoisting rope until it is so secured. Bundles of such joists shall be so placed as to prevent accidental dislodgment while being hoisted. Immediately upon the release of the ties or straps from such bundles, the individual joists shall be distributed to and placed in their permanent positions and secured against accidental dislodgment.
(3) Loads shall not be placed on open web steel joists until such joists are permanently located and secured including the installation of required bridging.
(b) Holing or cutting of structural steel members.
Load-bearing structural steel members shall not be materially weakened by holing, cutting or by any other means except in accordance with the advice of the designer thereof or of a professional engineer licensed to practice in the State of New York.
(c) Tag lines.
While steel panels or structural steel members are being hoisted, tag lines shall be provided and used to prevent uncontrolled movement of such panels or members.
(d) Erection of lintels.
Where exterior metal lintels are erected in steel or concrete frame buildings or other structures after the permanent floors have been installed, a suitable scaffold constructed and installed in compliance with this Part (rule) shall be provided and used unless each person engaged in the work of erecting such lintels is provided with and wears an approved safety belt or harness in compliance with this Part (rule).
(e) Tandem loads.
The suspension of tandem loads from the boom or hook of any crane or derrick over any area or location where persons work or pass is prohibited.
