Introduction
The purpose of this assessment is to evaluate a candidate’s proficiency in essential
construction safety protocols as required by state and federal regulations. This exam
assesses fundamental knowledge and the practical application of safety standards to ensure
a secure worksite environment. The structure includes multiple-choice and scenario-based
questions designed to test a candidate's ability to identify hazards, implement corrective
actions, and adhere to legal compliance. Emphasis is placed on real-world application and
critical decision-making, ensuring that individuals can effectively manage risks and maintain
professional ethics and standards within the Utah construction industry.
SECTION ONE: QUESTIONS 1–100
1. According to OSHA standards, at what height is fall protection generally required for
employees working in construction?
A. 4 feet B. 6 feet C. 10 feet D. 12 feet
B. 6 feet
Explanation: OSHA 1926.501(b)(1) mandates that each employee on a walking/working
surface with an unprotected side or edge which is 6 feet or more above a lower level shall be
protected from falling by the use of guardrail systems, safety net systems, or personal fall
arrest systems.
2. Which of the following is the primary responsibility of a "competent person" at a
construction site excavation?
A. Managing the payroll for all machine operators B. Inspecting the trench daily for evidence
of cave-ins or hazardous atmospheres C. Designing the architectural blueprints for the
foundation D. Operating the primary excavator for the duration of the project
B. Inspecting the trench daily for evidence of cave-ins or hazardous atmospheres
Explanation: A competent person is one who is capable of identifying existing and
predictable hazards and has the authority to take prompt corrective measures; for
excavations, they must inspect the site daily and after every rainstorm.
, 3. What color is typically used for safety signs that indicate "Danger" and represent
immediate hazards?
A. Yellow B. Green C. Red D. Blue
C. Red
Explanation: Red is the standard safety color used to identify "Danger," indicating an
immediate hazard which has a high probability of resulting in death or serious injury if not
avoided.
4. In a Personal Fall Arrest System (PFAS), what is the maximum allowable arresting
force that can be transmitted to an employee wearing a full-body harness?
A. 900 pounds B. 1,200 pounds C. 1,800 pounds D. 2,400 pounds
C. 1,800 pounds
Explanation: OSHA standards require that personal fall arrest systems, when used with a
full-body harness, be rigged such that an employee can neither free fall more than 6 feet nor
contact any lower level, and the maximum arresting force is limited to 1,800 pounds.
5. When using a portable ladder to access an upper landing surface, how many feet
must the ladder side rails extend above the upper landing surface?
A. 1 foot B. 2 feet C. 3 feet D. 5 feet
C. 3 feet
Explanation: To ensure stability and provide a handhold for employees stepping onto or
off the ladder, the side rails must extend at least 3 feet above the upper landing surface.
6. Under the Hazard Communication Standard (HCS), which document must be readily
accessible to employees for every hazardous chemical used on the job site?
A. Safety Data Sheet (SDS) B. Bill of Lading C. Chemical Purchase Order D. Environmental
Impact Study
A. Safety Data Sheet (SDS)
Explanation: Employers must maintain Safety Data Sheets for each hazardous chemical
in the workplace and ensure they are readily accessible during each work shift to employees
when they are in their work area.
7. Which of the following is a requirement for a trench that is 5 feet deep or greater?
A. It must be lined with plastic sheeting B. It must have a protective system such as shoring,
shielding, or sloping C. It must be inspected by a licensed architect every hour D. It must be
completely covered with plywood at night
, B. It must have a protective system such as shoring, shielding, or sloping
Explanation: Excavations 5 feet or deeper require a protective system to prevent cave-
ins, unless the excavation is made entirely in stable rock.
8. What is the minimum distance that a ladder must be placed away from the base of a
wall in relation to its working length (the 4-to-1 rule)?
A. One-half the working length B. One-third the working length C. One-fourth the working
length D. One-fifth the working length
C. One-fourth the working length
Explanation: For every 4 feet of ladder height, the base of the ladder should be moved 1
foot away from the wall to maintain a safe climbing angle.
9. A worker is assigned to a task involving high levels of silica dust. What is the first
priority in the hierarchy of controls to protect the worker?
A. Providing a N95 respirator B. Rotation of the worker to a different task C. Using water-fed
equipment or local exhaust ventilation to eliminate dust at the source D. Placing warning
signs around the work area
C. Using water-fed equipment or local exhaust ventilation to eliminate dust at the source
Explanation: Engineering controls, such as wet methods or ventilation, are prioritized in
the hierarchy of controls because they remove the hazard at the source before relying on
administrative controls or PPE.
10. Which class of hard hat is designed to provide protection against high-voltage
conductors (up to 20,000 volts)?
A. Class G (General) B. Class E (Electrical) C. Class C (Conductive) D. Class D (Decorative)
B. Class E (Electrical)
Explanation: Class E hard hats are tested to withstand 20,000 volts, providing the highest
level of protection against electrical hazards.
11. What is the required minimum distance between a crane boom and a power line
carrying 50kV?
A. 5 feet B. 10 feet C. 15 feet D. 20 feet
B. 10 feet
Explanation: For lines rated 50kV or below, OSHA requires a minimum clearance of 10
feet to prevent electrical arcing and electrocution.
