1. What is the primary safety concern when performing masonry work on
elevated structures?
A. Material cost
B. Fall protection
C. Mortar consistency
D. Tool availability
Answer: B. Fall protection
Rationale: Elevated masonry work exposes masons to fall hazards, making
fall protection systems and safety protocols the primary safety concern on
elevated job sites.
2. Which type of scaffold is most commonly used for masonry work at
elevations?
A. Suspended scaffold
B. Rolling scaffold
C. Frame scaffold
D. Outrigger scaffold
Answer: C. Frame scaffold
,Rationale: Frame scaffolds are modular, stable, and easily adjusted for
masonry work at various elevations, making them the most common choice
for elevated masonry construction.
3. When working around cranes and hoists on an elevated masonry project,
what is the most critical safety practice?
A. Wearing a hard hat
B. Maintaining communication with the operator
C. Working quickly
D. Using hand signals only
Answer: B. Maintaining communication with the operator
Rationale: Clear communication between ground personnel and crane/hoist
operators prevents accidents caused by unexpected load movements or
dropped materials.
4. What is the primary purpose of bracing a masonry wall during
construction?
A. Improve appearance
B. Resist wind and backfill forces
C. Reduce mortar usage
D. Speed curing
Answer: B. Resist wind and backfill forces
Rationale: Temporary bracing prevents newly constructed masonry walls
from collapsing due to wind loads or soil pressure before permanent
structural connections are complete.
5. When should bracing be removed from a masonry wall?
A. Immediately after the wall is laid
B. After the mortar has fully cured and permanent connections are in place
,C. When the wall reaches half height
D. The next day
Answer: B. After the mortar has fully cured and permanent connections are in
place
Rationale: Bracing must remain until the wall can independently resist design
loads, which requires sufficient mortar curing and completed structural tie-
ins.
6. What is the standard height at which fall protection is required in masonry
construction?
A. 4 feet
B. 6 feet
C. 10 feet
D. 15 feet
Answer: B. 6 feet
Rationale: OSHA regulations require fall protection when working at heights
of 6 feet or more in construction, including masonry operations.
7. When using a safety harness, what is the minimum required anchorage
strength?
A. 1,000 pounds
B. 2,500 pounds
C. 5,000 pounds
D. 10,000 pounds
Answer: C. 5,000 pounds
Rationale: OSHA requires personal fall arrest system anchorages to support
at least 5,000 pounds per worker attached.
8. What is the primary purpose of a control joint in masonry walls?
, A. Increase wall strength
B. Control cracking from movement
C. Improve insulation
D. Add decoration
Answer: B. Control cracking from movement
Rationale: Control joints create intentional weak planes that accommodate
movement from thermal expansion, contraction, and moisture changes,
preventing random cracking.
9. Where should control joints be placed in a masonry wall?
A. At corners only
B. At regular intervals and at openings
C. Only at the top of walls
D. Randomly throughout
Answer: B. At regular intervals and at openings
Rationale: Control joints are strategically placed at regular spacing (typically
20-25 feet) and at stress concentration points like openings to manage
movement effectively.
10. What is the maximum horizontal spacing typically recommended for
control joints in concrete masonry walls?
A. 10 to 15 feet
B. 20 to 25 feet
C. 30 to 35 feet
D. 40 to 50 feet
Answer: B. 20 to 25 feet
Rationale: Industry standards recommend control joint spacing of
approximately 20 to 25 feet for concrete masonry, though this can vary based
on wall height and reinforcement.
