,3. Which OSHA construction subpart contains general safety and health
provisions?
A. Subpart C
B. Subpart E
C. Subpart M
D. Subpart P
Correct Answer: A. Subpart C
Rationale: Subpart C contains general safety and health provisions for
construction. These provisions establish broad requirements concerning safe
work practices, accident prevention responsibilities, competent persons, and
related construction safety requirements.
4. Which party has the primary responsibility for providing a workplace
that complies with applicable OSHA requirements?
A. The individual employee only
B. The equipment manufacturer
C. The employer
D. The project visitor
Correct Answer: C. The employer
Rationale: Employers have primary responsibility for establishing and
maintaining safe working conditions and complying with applicable OSHA
requirements. This includes identifying hazards, implementing appropriate
controls, providing required training and PPE, and maintaining safe work
practices.
5. What is the most effective overall approach to managing construction
hazards?
A. Wait until an injury occurs before taking corrective action
B. Identify hazards and implement appropriate controls before workers are
exposed
C. Depend entirely on warning signs
D. Require workers to accept the hazards as part of the job
2
,Correct Answer: B. Identify hazards and implement appropriate controls
before workers are exposed
Rationale: Effective safety management is proactive. Employers should
identify hazards before work begins or as conditions change and then
implement controls using appropriate methods. Prevention is more effective
than relying solely on corrective action after an incident occurs.
6. Which OSHA construction subpart addresses personal protective and
life-saving equipment?
A. Subpart D
B. Subpart E
C. Subpart F
D. Subpart G
Correct Answer: B. Subpart E
Rationale: Subpart E addresses personal protective and life-saving
equipment. PPE is selected according to the hazards workers may encounter
and may include protection for the head, eyes, face, hands, feet, body, hearing,
respiratory system, and other areas.
7. When should an employer select PPE for construction workers?
A. Based primarily on the employee's preferred style
B. Based on the hazards identified during the workplace assessment
C. Based only on the cheapest available equipment
D. Based on the employee's job title without evaluating the work
Correct Answer: B. Based on the hazards identified during the workplace
assessment
Rationale: PPE selection must correspond to the hazards associated with the
work. An effective hazard assessment identifies the type and severity of
exposure so that appropriate protective equipment can be selected, properly
fitted, maintained, and used.

, 8. Which OSHA construction subpart addresses occupational health and
environmental controls?
A. Subpart C
B. Subpart D
C. Subpart I
D. Subpart M
Correct Answer: B. Subpart D
Rationale: Subpart D addresses general environmental controls in
construction. It includes requirements related to workplace environmental
conditions and protections intended to reduce health and safety hazards
associated with construction operations.
9. Which substance is specifically addressed by OSHA's construction
standard for respirable crystalline silica?
A. Carbon monoxide
B. Respirable crystalline silica
C. Nitrogen
D. Helium
Correct Answer: B. Respirable crystalline silica
Rationale: Construction activities such as cutting, drilling, grinding, and
crushing certain materials can generate respirable crystalline silica. Inhalation
of respirable silica can cause serious occupational disease, making exposure
assessment and appropriate engineering and work-practice controls essential.
10. Which OSHA construction subpart primarily addresses excavation
and trenching?
A. Subpart L
B. Subpart M
C. Subpart P
D. Subpart X
Correct Answer: C. Subpart P
