,Section A - Concrete Materials AND Properties
Q1.
During a concrete pour on a high-rise project, the pump operator notices a sudden drop in
hydraulic pressure. The safety manager must decide the immediate course of action. What
is the most appropriate response?
A. Stop the pour and evacuate the area B. Continue the pour but reduce the
around the pump. pumping rate.
C. Immediately retract the boom to relieve D. Instruct workers to move away from the
pressure. pour area but continue pumping.
Correct: A - Stop the pour and evacuate the area around the pump.
Rationale:A sudden drop in hydraulic pressure may indicate a critical failure in the pump
system. Stopping the pour and evacuating the area prevents potential injuries from a boom
collapse or hose failure. Continuing operations would endanger workers.
Why the other answers are wrong:
B. Continuing the pour risks catastrophic failure and worker injury.
C. Retracting the boom may worsen the failure and is not the first priority; evacuation is
paramount.
D. Continuing pumping while workers move is insufficient; the pump must be stopped to ensure
safety.
Reference: NYC DOB Concrete Safety Manager Study Guide, Chapter 5: Pump Operations and Safety
Q2.
A concrete safety manager is reviewing a formwork design for a 20-foot-high wall. The
formwork will be subjected to a hydrostatic pressure of 1,500 psf. Which factor most
critically affects the lateral pressure exerted by fresh concrete on the formwork?
A. The temperature of the concrete B. The height of the formwork
C. The rate of placement D. The type of cement used
Correct: C - The rate of placement
Rationale:The rate of placement directly influences the hydrostatic pressure of fresh
concrete; faster placement increases pressure. Temperature affects setting time but not
directly the maximum lateral pressure. Height is already accounted for in the given pressure.
Cement type affects setting but not the pressure calculation.
Why the other answers are wrong:
A. Temperature influences setting time but not the peak lateral pressure as directly as
placement rate.

, Section A - Concrete Materials AND Properties
B. Height is already incorporated in the pressure value given.
D. Cement type affects hydration but not the hydrostatic pressure.
Reference: ACI 347-04: Guide to Formwork for Concrete, Section 2.2
Q3.
Under the NYC DOB Concrete Safety Manager requirements, when must a concrete safety
manager be present on a job site?
A. Only during concrete placement B. During all concrete operations including
operations formwork and rebar installation
C. Only when the concrete pour exceeds 50 D. During all construction activities on the
cubic yards site
Correct: B - During all concrete operations including formwork and rebar installation
Rationale:NYC DOB rules require the concrete safety manager to be present during all
concrete operations, which include formwork, rebar, and placement. This ensures oversight of
the entire concrete construction process, not just the pour.
Why the other answers are wrong:
A. Presence is required for more than just placement.
C. There is no volume threshold for presence.
D. The requirement is specific to concrete operations, not all construction.
Reference: NYC DOB Concrete Safety Manager License Requirements, Section 3310.1
Q4.
Given the following concrete mix design: water-cement ratio = 0.45, cement content = 600
lb/yd³, and a specified compressive strength of 5,000 psi at 28 days. Which adjustment
will most effectively increase the early-age strength (1-day) without compromising the
28-day strength?
A. Increase the water-cement ratio to 0.50 B. Use a Type III high-early-strength cement
C. Add more coarse aggregate to the mix D. Decrease the curing temperature
Correct: B - Use a Type III high-early-strength cement
Rationale:Type III cement hydrates faster, increasing early strength while maintaining the
same 28-day strength potential if the water-cement ratio is unchanged. Increasing
water-cement ratio would reduce strength. Adding aggregate does not significantly affect
early strength. Decreasing curing temperature slows hydration.
Why the other answers are wrong:
A. Higher water-cement ratio reduces both early and ultimate strength.
C. Coarse aggregate content has minimal effect on early strength.
D. Lower curing temperature slows hydration and reduces early strength.
