1. What is the leading cause of death on construction sites annually?
A) Electrocution
B) Caught-in/between accidents
C) Falls (CORRECT ANSWER)
D) Struck-by accidents
Rationale: Falls from elevation (ladders, scaffolds, roofs) consistently
account for the highest percentage of fatalities in the construction
industry. OSHA identifies falls as the leading cause of death in
construction, often termed the "Fatal Four" along with electrocution,
caught-in/between, and struck-by accidents.
2. OSHA's primary mission is to:
A) Ensure every worker has health insurance
,B) Assure safe and healthful working conditions (CORRECT
ANSWER)
C) Maximize construction productivity
D) Reduce construction costs
Rationale: The Occupational Safety and Health Administration
(OSHA) was created to assure safe and healthful working conditions
by setting and enforcing standards and providing training, outreach,
education, and assistance.
3. According to the hierarchy of controls, which is the MOST
effective method for protecting workers from an occupational
hazard?
A) Personal Protective Equipment (PPE)
B) Engineering Controls (e.g., machine guards) (CORRECT
ANSWER)
C) Administrative Controls (e.g., warnings)
D) Work Practices
Rationale: The hierarchy of controls prioritizes eliminating hazards
at the source. Engineering controls (guards, ventilation, isolation) are
higher than administrative controls and PPE, which is the last line of
defense.
,4. Personal Protective Equipment (PPE) should be used:
A) As the first line of defense against hazards
B) After engineering and administrative controls are exhausted
(CORRECT ANSWER)
C) Only when working overtime
D) Instead of safety training
Rationale: PPE is the last line of defense after eliminating,
substituting, or controlling hazards through engineering and
administrative controls. It should never replace engineering controls
or safety training.
5. What is the minimum distance from an unguarded edge at which
fall protection is required for construction workers according to
OSHA?
A) 3 feet
B) 6 feet (CORRECT ANSWER)
C) 10 feet
D) 15 feet
, Rationale: OSHA's standard 29 CFR 1926.501 requires fall
protection at 6 feet in the construction industry (distinct from general
industry, which is usually 4 feet).
6. Which of these is a true statement regarding safety?
A) Safety is a learned behavior and attitude (CORRECT ANSWER)
B) Safety is an innate instinct
C) Safety only depends on equipment
D) Safety is the sole responsibility of the supervisor
Rationale: Safety is a learned behavior and attitude that must be
developed through training, practice, and conscious effort. It is not
instinctive and requires ongoing commitment from all workers.
7. A measure of the probability, consequences, and exposure related
to an event is referred to as _____.
