1. Which of the following is the primary purpose of a Job Safety
Analysis (JSA)?
A. To document employee attendance
B. To identify potential hazards and control measures
C. To evaluate productivity
D. To calculate project costs
B. To identify potential hazards and control measures
Rationale: A JSA systematically identifies potential hazards for each
job task and implements controls to reduce the risk of accidents.
2. OSHA requires that employers provide fall protection for employees
working at heights of:
A. 4 feet
B. 5 feet
C. 6 feet
D. 10 feet
C. 6 feet
Rationale: OSHA standards mandate fall protection for construction
workers at heights of 6 feet or more.
,3. Which fire extinguisher type should be used for electrical fires?
A. Water
B. Foam
C. CO2
D. Wet chemical
C. CO2
Rationale: CO2 extinguishers are non-conductive and effective for
electrical fires.
4. What is the first step in conducting a hazard assessment on a
construction site?
A. Implement controls
B. Identify hazards
C. Train employees
D. Record findings
B. Identify hazards
Rationale: Identifying hazards is the first step in any hazard
assessment to understand what risks exist before implementing
controls.
5. Lockout/Tagout procedures are intended to:
A. Prevent theft of equipment
B. Protect workers from hazardous energy
C. Improve productivity
D. Track equipment usage
B. Protect workers from hazardous energy
Rationale: Lockout/Tagout ensures that machines are de-energized

,6. PPE is considered the last line of defense in the hierarchy of
controls. What is the first line of defense?
A. Engineering controls
B. Administrative controls
C. Work practice controls
D. Substitution
A. Engineering controls
Rationale: Engineering controls eliminate or reduce hazards at the
source, making them the most effective control measure.
7. Which of the following is a common hazard in trenching operations?
A. Noise
B. Collapse or cave-in
C. Dust inhalation
D. Slips on ladders
B. Collapse or cave-in
Rationale: Trenching presents a high risk of cave-ins, which is the
leading cause of fatalities in trenching operations.
8. The primary purpose of a safety meeting (toolbox talk) is to:
A. Discuss employee benefits
B. Review daily safety hazards and precautions
C. Record employee attendance
D. Evaluate project schedules
B. Review daily safety hazards and precautions

Rationale: OSHA standard 29 CFR 1926 contains all regulations
specifically related to construction safety.
10. What is the maximum allowable slope for a trench deeper than 20
feet to prevent cave-ins?
A. 1:1
B. 1:1.5
C. 1:2
D. 1:0.5
B. 1:1.5
Rationale: OSHA specifies protective sloping for trenches deeper than
20 feet at a 1:1.5 slope depending on soil type to prevent cave-ins.
11. Which of the following is considered an administrative control?
A. Guardrails
B. Job rotation to reduce fatigue
C. Machine guarding
D. Ventilation systems
B. Job rotation to reduce fatigue
Rationale: Administrative controls involve changing the way people
work, such as schedules, rotation, and training.
12. Hearing protection is required when noise levels exceed:
A. 75 dBA
B. 80 dBA
