Explanation: California requires a minimum of 4 years of journey-level experience within the last 10 years in fire protection work to qualify for the C-16 license. The qualifier must be at least 18 years old and must pass both the trade and law exams administered by the CSLB.

3What exams must a California C-16 qualifier pass?

A.Only a trade knowledge exam

B.Only a business law exam

C.Both a trade knowledge exam and a law and business exam

D.No exams are required

Explanation: California C-16 applicants must pass two examinations: the Fire Protection trade knowledge exam and the Law and Business exam. The trade exam covers planning/estimating, underground installation, fire protection system installation, maintenance/repair, and safety. Both are closed-book, multiple-choice exams.

4According to California's CSLB, what is the contractor bond amount required for C-16 licensees?

A.$10,000

B.$15,000

C.$25,000

D.$50,000

Explanation: California requires all licensed contractors, including C-16 Fire Protection contractors, to maintain a $25,000 contractor bond. This bond protects the public by providing a source of compensation if the contractor fails to fulfill contractual obligations or violates licensing laws.

5What percentage of the C-16 trade exam covers Installation of Fire Protection Systems?

A.9%

B.21%

C.25%

D.36%

Explanation: The California C-16 Fire Protection trade exam dedicates 36% of questions to Installation of Fire Protection Systems, making it the largest section. This includes installing sprinkler systems, preaction and deluge systems, storage tanks and fire pumps, and fire suppression systems.

6Per NFPA 13, what is the maximum coverage area per sprinkler for Light Hazard Occupancy?

A.130 sq ft

B.168 sq ft

C.200 sq ft

D.225 sq ft

Explanation: NFPA 13 specifies a maximum coverage area of 200 square feet per standard spray sprinkler head for Light Hazard Occupancy. This determines maximum spacing between heads and ensures adequate water distribution across the protected area.

7In California, C-16 contractors working on commercial or multi-family fire protection systems must have employees with what certification?

A.NICET Level III

B.OSHA 30-hour certificate

C.Fire Sprinkler Fitter Certification

D.EPA lead certification

Apprentices must obtain a Fire Sprinkler Fitter Registration.

8What type of sprinkler system uses closed heads on piping filled with pressurized air?

A.Wet pipe system

B.Dry pipe system

C.Deluge system

D.Antifreeze system

Explanation: A dry pipe system uses closed sprinkler heads on piping containing pressurized air or nitrogen. When a head activates, air escapes, opening the dry pipe valve to admit water. These systems protect areas subject to freezing, though much of California's mild climate makes wet pipe systems more common.

9What is the standard K-factor for a standard spray sprinkler head?

A.2.8

B.4.2

C.5.6

D.8.0

Explanation: The standard K-factor for a standard spray sprinkler head is 5.6. The discharge formula Q = K times the square root of P determines flow, where Q is in gpm and P is in psi. At the minimum 7 psi, a K-5.6 head discharges approximately 14.8 gpm.

10In California, what is the minimum project value requiring a contractor license?

A.$200

B.$500

C.$1,000

D.$2,500

Explanation: California requires a contractor license for any construction project valued at $500 or more in combined labor and materials. This threshold applies to all fire sprinkler work, making even relatively small installations subject to licensing requirements.
