SECTION 1: DEFINITIONS AND FUNDAMENTAL CONCEPTS
Question 1
A struck-by hazard can be described as anytime a worker:
A) Falls from a height of greater than ten feet
B) Is hit by a falling, swinging, flying, or rolling object
C) Can get any part of his/her body caught in or between objects
D) Comes into contact with an electrical current
Answer: B
Rationale: A struck-by incident occurs when forcible contact or
impact happens between a person and an object or piece of
equipment. The key distinction is that the impact alone creates the
injury, unlike caught-in/between incidents where crushing force
between two objects causes the injury .
Question 2
Which of the following correctly describes the difference between a
struck-by incident and a caught-in/between incident?
,A) In a struck-by incident, the impact alone creates the injury; in a
caught-in/between incident, the injury results from crushing force
between two objects
B) Struck-by incidents are always less severe than caught-in/between
incidents
C) Caught-in/between incidents only involve machinery, while struck-
by incidents involve vehicles
D) There is no difference; the terms are interchangeable
Answer: A
Rationale: The critical distinction is that struck-by incidents result
from impact alone, while caught-in/between incidents occur when an
injury results from crushing force between two objects.
Understanding this difference is essential for proper hazard
classification and prevention .
Question 3
The four categories of struck-by hazards are:
A) Struck by moving vehicle, struck by falling object, struck by flying
object, struck by swinging object
B) Struck by falling object, struck by flying object, struck by rolling
object, struck by swinging object
C) Struck by flying object, struck by falling object, struck by swinging
object, struck by rolling object
D) Struck by equipment, struck by materials, struck by vehicles,
struck by tools
Answer: C
Rationale: OSHA categorizes struck-by hazards into four primary
types: flying objects (tools, materials, or debris ejected), falling
objects (from scaffolding, cranes, or building structures), swinging
objects (crane loads, equipment booms), and rolling objects (vehicles,
equipment, materials) .
,Question 4
Construction has the highest rate of struck-by incidents of any
industry. What percentage of all construction fatalities are attributed
to struck-by hazards?
A) Approximately 5%
B) Approximately 10%
C) Approximately 25%
D) Approximately 40%
Answer: B
Rationale: According to BLS reports, struck-by hazards combined with
caught-in/between account for approximately 10% of construction
worker deaths. Falls remain the leading cause at 39%, with
electrocutions at approximately 6% .
Question 5
In 2023, out of 1,075 total construction deaths, struck-by and caught-
in/between hazards accounted for:
A) 421 deaths
B) 66 deaths
C) At least 111 deaths
D) 598 deaths
Answer: C
Rationale: BLS data for 2023 shows that struck-by and caught-
in/between hazards combined resulted in at least 111 deaths (~10%
of construction fatalities). Falls accounted for 421 deaths (39%), and
electrocutions accounted for 66 deaths (6%) .
, Question 6
A worker is hit by a piece of debris that flies out from a grinding
wheel. This is an example of what type of struck-by hazard?
A) Struck by falling object
B) Struck by flying object
C) Struck by swinging object
D) Struck by rolling object
Answer: B
Rationale: Flying object hazards occur when objects are ejected or
propelled through the air. This includes debris from tools, parts from
equipment under power, or materials that break apart. Abrasive
wheel machinery shattering can send pieces flying at speeds up to
300 mph .
Question 7
A steel beam being hoisted to the next level swings and hits a
worker. This is classified as:
A) Struck by falling object
B) Struck by flying object
C) Struck by swinging object
D) Struck by rolling object
Answer: C
Rationale: Swinging object hazards occur when suspended loads or
equipment booms move in an arc and strike workers. This commonly
happens during crane operations when loads swing unexpectedly, or
when workers are within the swing radius of equipment .
Question 8
A worker is struck by materials that fall from scaffolding above. This
is an example of:
