Introduction
This comprehensive assessment evaluates the critical knowledge and applied safety management competencies
required for the Construction Site Safety Technician (CSST) certification examination. The test assesses the
candidate's ability to interpret and enforce Occupational Safety and Health Administration (OSHA) standards
within the dynamic and high-hazard environment of a construction worksite. Using a rigorous multiple-choice and
scenario-based format, this examination challenges the learner to apply hazard recognition, risk assessment, and
control hierarchy principles to prevent injuries and fatalities. Success requires proficiency in fall protection,
,excavation safety, electrical safety, scaffold inspection, and the leadership and communication skills essential for
effective site safety management and the promotion of a proactive safety culture.
SECTION ONE: Questions 1–100
Question 1
According to OSHA regulations, an employer must provide a workplace free from recognized hazards. This
foundational principle is derived from which section of the OSH Act?
A. Section 11(c) - Whistleblower Protection
B. Section 5(a)(1) - The General Duty Clause
C. Section 8 - Recordkeeping
D. Section 18 - State Plans
🟢 Correct Answer:
B
🔴 RATIONALE:
The General Duty Clause, Section 5(a)(1) of the Occupational Safety and Health Act of 1970, states that each
employer shall furnish to each of his employees a place of employment which is free from recognized hazards
that are causing or are likely to cause death or serious physical harm. This is the foundational principle of all
OSHA enforcement and is used to cite hazards for which there is no specific standard. Section 11(c) protects
employees from retaliation for filing a complaint.
Question 2
A construction safety technician observes a worker standing on the top cap of a stepladder to reach an
overhead conduit. What is the most appropriate immediate action?
A. Instruct the worker to have another employee hold the ladder.
,B. Immediately direct the worker to climb down, and inform them that standing on the top cap is strictly
prohibited.
C. Allow the worker to finish the task since it will only take a minute.
D. Document the violation for end-of-day reporting.
🟢 Correct Answer:
B
🔴 RATIONALE:
OSHA and manufacturer standards strictly prohibit standing on the top cap or top step of a stepladder. The top
cap is not designed to support a worker's weight, and doing so creates a severe fall hazard due to the lack of a
point of support above the step. The safety technician has a duty to intervene immediately when an imminent
danger situation is observed, not merely to document it for later action.
Question 3
Which OSHA standard, commonly referred to as the "Fatal Four" focus areas, addresses the most common
causes of fatalities in the construction industry?
A. OSHA Part 1910 - General Industry
B. OSHA Part 1926 - Construction, specifically focusing on falls, struck-by, caught-in/between, and electrocution
hazards.
C. OSHA Part 1904 - Recordkeeping
D. OSHA Part 1928 - Agriculture
🟢 Correct Answer:
B
🔴 RATIONALE:
OSHA has identified the "Focus Four" (or "Fatal Four") hazards in construction: Falls, Struck-by, Caught-
in/between, and Electrocution. These four hazard categories account for the overwhelming majority of
, construction worker fatalities annually. OSHA's construction standards are contained in 29 CFR Part 1926, and a
primary function of a CSST is to recognize and mitigate these four specific hazard categories.
Question 4
When must an employer conduct a job hazard analysis (JHA) for a construction task?
A. Only when a project exceeds $1 million in value.
B. Only after a serious injury has occurred on the site.
C. Before a new, complex, or high-hazard task is performed, or when the task has a history of causing injuries.
D. Annually, during the company's insurance audit.
🟢 Correct Answer:
C
🔴 RATIONALE:
A Job Hazard Analysis (JHA), also called a Job Safety Analysis (JSA), is a proactive technique that focuses on job
tasks as a way to identify hazards before they occur. It should be performed for any task that is new,
infrequently performed, complex, or has a history of producing injuries or near misses. It is a dynamic
prevention tool, not a reactive or solely periodic administrative requirement.
Question 5
A construction crew is preparing to begin an excavation. The project plans show existing underground electrical
conduits. What is the first required step before any digging begins?
A. Order an emergency power shut-down from the utility company.
B. Call the local one-call utility notification center (811) to have the underground utilities located and marked.
C. Begin hand-digging carefully with insulated tools.
D. Apply for a hot-work permit.
