Question

what is the main factor to consider when anchoring a suspension scaffold?

the tieback can be secured to vents or piping

the scaffold can be suspended without tiebacks if balanced properly

the anchorage must support four times the intended load of the scaffold

the weight of the scaffold is not a concern if it is hanging securely

Explanation:

Analyze OSHA suspension scaffold anchoring requirements

OSHA standard 1926.451(d)(1) requires that suspension scaffold outrigger beams, cornices, parapets, or other anchorage points must be capable of supporting, without failure, at least 4 times the load imposed on them by the scaffold operating at its rated load.

Evaluate the given options

• Option 1: Tiebacks must never be secured to vents, piping, or electrical conduits because they lack structural integrity.
• Option 2: Tiebacks are always required for suspension scaffolds to prevent tipping or displacement.
• Option 3: The anchorage must support four times the intended load of the scaffold, which matches the 4:1 safety factor requirement.
• Option 4: The weight of the scaffold is a primary concern for structural capacity calculations.

Answer:

• (A) The tieback can be secured to vents or piping
• (B) The scaffold can be suspended without tiebacks if balanced properly
• (C) The anchorage must support four times the intended load of the scaffold (Correct answer)
• (D) The weight of the scaffold is not a concern if it is hanging securely
