Fall protection systems and practices(k) Fall protection plans
Only available for leading edge work, precast concrete erection, or residential construction work.
Fall protection systems & practices
• Demonstrated unfeasibility or greater hazard
• Prepared/implemented by qualified person for each site
• Maintained up to date• Can only be changed by qualified
person
Fall protection systems and practices
• Must be at a site• Document why plan is needed• Include a written discussion of other
measures to reduce or eliminate hazards
• Identify each location where plan is needed

This is a controlling employer standard.
New Steel Erection Standard
Approval to begin steel erection. Before authorizing the commencement of steel erection, the controlling contractor shall ensure that the steel erector is provided with the following written notifications:
New Steel Erection Standard
The concrete in the footings, piers and walls and the mortar in the masonry piers and walls has attained, on the basis of an appropriate ASTM standard test method of field-cured samples, either 75% of the intended minimum compressive design strength or sufficient strength to support the loads imposed during steel erection.
New Steel Erection Standard
Any repairs, replacements and modifications to the anchor bolts were conducted in accordance with Sec. 1926.755(b).
New Steel Erection Standard
Commencement of steel erection. A steel erection contractor shall not erect steel unless it has received written notification that the concrete in the footings, piers and walls or the mortar in the masonry piers and walls has attained, on the basis of an appropriate ASTM standard test method of field-cured samples, either 75% of the intended minimum compressive design strength or sufficient strength to support the loads imposed during steel erection.
New Steel Erection Standard
Site Layout. The controlling contractor shall ensure that the following is provided and maintained:
Adequate Access roads into and through the site for the safe delivery and movement of derricks, cranes, trucks, other necessary equipment.
A firm, properly graded, drained area, readily accessible to the work with adequate space for the safe storage of materials and the safe operation of the erector’s equipment.
Pre-planning of overhead hoisting operations.
Site-specific erection plan.
Protection from materials being hoisted
Custody of fall protection. Fall Protection provided by the steel erector shall remain in the area where steel erection activity has been completed, to be used by other trades, only if the controlling contractor or its authorized representative:
Has directed the steel erector to leave the fall protection in place; and
