Scaffold Design

The weight of materials, equipment, and workers is known as the intended live load.

• true
• false

The average weight used for one worker and his or her tools is which of the following?

• 175 pounds
• 200 pounds
• 225 pounds
• 250 pounds

Because of the possible configuration of a scaffold, a single scaffold leg/standard may carry a maximum contributory area of which of the following?

• 1/4 platform
• 1/2 platform
• 3/4 platform
• full platform

Contributory area is a portion of the platform that is supported by an individual scaffold leg/standard (True; False)

• true
• false

A scaffold bay is a section of the scaffold that is supported by four legs/standards. (True; False)

• true
• false

A uniform distributed load (UDL) is a load that is distributed unevenly over a given area. (True; False)

• true
• false

A point load is the point or place where the weight of the load is most concentrated and deflection is the greatest. (True; False)

• true
• false

If point loading is necessary, the best location is over the bearer/transom and as close to the leg/standard as possible. (True; False)

• true
• false

With a light-duty rating, the scaffold is allowed a UDL of no more than which of the following?

• 25 PSF
• 50 PSF

Medium-duty scaffold components should not exceed a length of which of the following?

• 6´-0˝
• 7´-0˝
• 8´-0"
• 9´-0˝
