1. A Texas Construction Safety Officer is reviewing a jobsite where
employees are working 18 feet above ground on a commercial
building. Which OSHA requirement applies?

B. Fall protection is required at 6 feet or higher.
C. Fall protection is only required for steel erection.
D. Fall protection is optional if employees have more than five years of
experience.
Answer: B. Fall protection is required at 6 feet or higher.
Rationale: Under OSHA Construction Standard 29 CFR 1926.501,
employees exposed to falls of 6 feet or more must be protected by
guardrails, personal fall arrest systems, or safety nets unless a specific
exception applies. Texas construction projects operating under OSHA
must follow this requirement.
2. Which OSHA regulation specifically governs construction safety
standards?
A. 29 CFR 1910
B. 29 CFR 1926
C. 29 CFR 1904
D. 29 CFR 1915
1

what maximum allowable slope for excavations less than 20 feet
deep?
A. ½:1
B. ¾:1
C. 1:1
D. 1½:1
Answer: D. 1½:1
Rationale: Type C soil is the least stable soil classification and requires
the greatest degree of protection. OSHA permits a maximum slope of 1.5
horizontal to 1 vertical (34 degrees) unless a protective system designed
by a registered professional engineer is used.
4. Which individual is responsible for identifying existing and
predictable hazards on a construction site and has authority to take
corrective action?
A. Project Owner
B. Competent Person
C. Qualified Person
D. Building Inspector

A. Fire, chemicals, noise, vibration
B. Falls, struck-by, caught-in/between, electrocution
C. Heat, cold, fatigue, ergonomics
D. Silica, asbestos, lead, mold
Answer: B. Falls, struck-by, caught-in/between, electrocution
Rationale: OSHA identifies these four hazards as the leading causes of
fatalities in construction. Eliminating them significantly reduces
occupational deaths.
7. Which ladder defect requires immediate removal from service?
A. Slight paint discoloration
B. Missing safety label
3
, C. Cracked side rail
D. Dirty steps
Answer: C. Cracked side rail

surface should be:
A. 1 foot
B. 2 feet
C. 3 feet
D. 5 feet
Answer: C. 3 feet
Rationale: OSHA requires portable ladders used for upper-level access
to extend at least 3 feet above the landing to provide secure handholds
during transition.
9. A personal fall arrest system must limit the maximum arresting
force on an employee wearing a full-body harness to:
A. 900 pounds
B. 1,200 pounds
C. 1,800 pounds
