Questions 1–8 — Florida Laws, Licensing & Safety
QUESTION 1
A contractor begins fabricating ductwork before obtaining the required permit for a
commercial renovation. Which consequence is the greatest regulatory concern?
A. Fabrication is prohibited without engineer approval.
B. The contractor may be subject to enforcement action because work requiring a
permit generally cannot legally proceed before permit issuance.
C. Fabrication voids the manufacturer's warranty.
D. Only the building owner can be cited.
Correct Answer: B. The contractor may be subject to enforcement action because
work requiring a permit generally cannot legally proceed before permit issuance.
Explanation: Florida construction work requiring permits generally must not begin until
the proper permit has been issued. Beginning work prematurely may result in fines,
stop-work orders, or disciplinary action. Engineer approval does not replace permitting,
warranties are unrelated, and both contractors and owners may bear responsibility
depending on the circumstances.
QUESTION 2
During rooftop duct installation, employees are working within 4 feet of an
unprotected roof edge. Which OSHA control should receive the highest priority?
,A. Require employees to wear leather gloves.
B. Install or provide an approved fall protection system.
C. Increase work speed to reduce exposure time.
D. Assign an additional supervisor only.
Correct Answer: B. Install or provide an approved fall protection system.
Explanation: Fall hazards are among the leading causes of construction fatalities. OSHA
requires appropriate fall protection when employees are exposed to qualifying fall
hazards. Gloves, supervision, and working faster do not eliminate the fall risk.
QUESTION 3
Who is ultimately responsible for ensuring that installed sheet metal systems comply
with approved construction documents?
A. Material supplier
B. Equipment manufacturer
C. Licensed contractor responsible for the installation
D. Utility company
Correct Answer: C. Licensed contractor responsible for the installation.
Explanation: The licensed contractor performing the work bears primary responsibility
for code-compliant installation. Suppliers and manufacturers provide products, but
installation compliance remains the contractor's responsibility. Utilities generally have
no role in installation compliance.
QUESTION 4
A project specification conflicts with the mechanical code. Which document generally
governs minimum safety requirements?
, A. Shop drawings
B. Manufacturer advertisements
C. Mechanical code requirements
D. Equipment catalog
Correct Answer: C. Mechanical code requirements.
Explanation: Building and mechanical codes establish enforceable minimum safety
standards. Specifications may exceed code requirements but generally cannot reduce
required safety provisions. Catalogs and advertisements are not regulatory documents.
QUESTION 5
A supervisor notices that employees are using damaged extension cords to power
fabrication equipment. What should be done first?
A. Continue using them until replacements arrive.
B. Repair them with tape only.
C. Remove the damaged cords from service immediately.
D. Reduce voltage supplied to the cords.
Correct Answer: C. Remove the damaged cords from service immediately.
Explanation: Damaged electrical cords present shock and fire hazards and must be
removed from service. Tape repairs alone are generally insufficient for damaged
conductors. Lower voltage does not eliminate insulation failures.
QUESTION 6
Which document most accurately defines the required dimensions and layout of
fabricated duct sections?
