Question 1

Materials stocked on the scaffold should never be placed directly over the scaffolding frame.

Accepted Answer

Materials can be placed directly over the scaffolding frame if the scaffold is designed to support the load without risk of collapse or instability, ensuring it does not exceed the maximum intended load or compromise the structural integrity of the scaffold.

Question 2

______ are also know as blocking boards.&#10;A) Foot boards&#10;B) Scaffold legs&#10;C) Ground plates&#10;D) End blocks

Accepted Answer

A

Question 3

_____ are crosspieces of heavy timber or steel beam, one end of which rests in a hole left in the wall, with the other end resting on solid ground or on a suitable base.&#10;A) Braces&#10;B) Putlogs&#10;C) Plankings&#10;D) Brackets

Accepted Answer

The described elements are putlogs, which are indeed crosspieces of heavy timber or steel beams that rest on a hole in the wall and solid ground or a base. Braces are diagonal members that add stability to a structure, while brackets are projections used to support other elements. Plankings refer to the wooden planks that are placed over scaffolding to create the working platform.

Question 4

Guardrails, toe boards, and midrails should be on all steel scaffolds ______ .&#10;A) at elevations of at least 5'&#10;B) at elevations of 6' or more&#10;C) at any elevation greater than 4'&#10;D) regardless of elevation

Accepted Answer

Guardrails, toe boards, and midrails are required on all steel scaffolds at elevations of 6 feet or more to prevent falls and ensure the safety of workers.

Question 5

Where persons are required to work or pass under the scaffold, scaffolds shall be provided with a screen between the toeboard and the guardrail.

Accepted Answer

This is required by OSHA regulations (29 CFR 1926.451(b)(10)). The screen helps prevent objects from falling off the scaffold and hitting workers or pedestrians below.

Question 6

According to the 29 CFR 1926, toeboards shall be _____ .&#10;A) a minimum of 4&#34; in height&#10;B) no more than 3&#34; in height&#10;C) exactly 5&#34; in height&#10;D) a maximum of 4&#34; in height

Accepted Answer

According to 29 CFR 1926, toeboards must be a minimum of 4 inches in height to provide adequate protection against the falling of tools and materials.

Question 7

OSHA estimates that as many as _____ accidents can be prevented annually if construction sites are compliant with current safety standards.&#10;A) 4500&#10;B) 7500&#10;C) 10000&#10;D) 12500

Accepted Answer

The answer of OSHA estimates that as many as _____...

Question 8

Scaffold legs can rest on hollow block.

Accepted Answer

Scaffold legs need a solid, stable base to ensure safety and stability; resting them on hollow blocks can lead to collapse or failure due to the blocks' insufficient strength and stability.

Question 9

The board on which the scaffolding rests is known as the _____ .&#10;A) scaffold sill&#10;B) brace plate&#10;C) frame&#10;D) scaffold leg

Accepted Answer

The term used to describe the board on which the scaffolding rests is "scaffold sill." Choice B is incorrect because a brace plate is a component used to connect the scaffolding frame to the scaffold tube. Choice C is incorrect because the frame refers to the structure of the scaffolding, not the board on which it rests. Choice D is incorrect because a scaffold leg is a component that supports the weight of the scaffold, not the board on which it rests.

Question 10

As a rule, the mason does not use rolling scaffolds, but they are sometimes used on small repair jobs or when pointing joints.

Accepted Answer

Rolling scaffolds are not typically used by masons, but may be used in certain situations such as small repair jobs or pointing joints.
