Answer: 80% of liquid capacity
Rationale: NFPA 58 § 5.2.3 and 49 CFR 173.301 require cylinders to be filled to no more than
80% to allow for vapor expansion.
Q03 Which of the following is the correct pressure relief valve setting for a 420 lb (100 gal)
ASME LP gas container?
Answer: 250 psig
Rationale: NFPA 58 § 5.9.2.5 requires relief valves on ASME containers to be set at 250 psig.
Q04 What is the minimum distance required between an underground LP gas container and a
building foundation?
Answer: 10 feet
Rationale: NFPA 58 § 6.4.4.1 requires a minimum 10-foot separation from underground
containers to building foundations.
,Q05 Which regulator is required on the first stage of a two-stage regulator system for residential
LP gas service?
Answer: High-pressure regulator (10–20 psig outlet)
Rationale: NFPA 58 § 6.11.3 requires the first-stage regulator to reduce tank pressure to 10–20
psig before the second-stage regulator drops it to 11 inches w.c.
Q06 What is the maximum length allowed for a flexible connector between the first-stage
regulator and the second-stage regulator?
Answer: 6 feet
Rationale: NFPA 58 § 6.11.3.3 limits flexible connectors in two-stage systems to 6 feet
maximum length.
Q07 When installing an LP gas container, what is the required clearance above the relief valve
discharge outlet?
Answer: 5 feet vertically from any opening into a building
Rationale: NFPA 58 § 6.4.5.3 requires the relief valve discharge to be at least 5 feet vertically
above any building opening.
Q08 Which of the following is required on all LP gas containers over 125 gallons water
capacity?
Answer: Fixed maximum liquid level gauge
Rationale: NFPA 58 § 5.9.4 requires a fixed maximum liquid level gauge (outage gauge) on
containers over 125 gallons.
Q09 What is the minimum burial depth for underground LP gas piping?
Answer: 12 inches
, Rationale: NFPA 58 § 6.24.3 requires underground metallic piping to be buried at least 12
inches deep.
Q10 Which material is NOT permitted for underground LP gas piping in Florida?
Answer: PVC
Rationale: NFPA 58 § 6.24.2 permits only steel, copper, or polyethylene (PE) for underground
piping. PVC is prohibited.
Q11 What is the required test pressure for new underground LP gas piping?
Answer: Not less than 1.5 times the proposed maximum operating pressure for 3 hours
Rationale: NFPA 58 § 6.24.6 requires pressure testing at 1.5 times operating pressure for 3
hours.
Q12 Which of the following is the correct location for the container shutoff valve?
Answer: At the container outlet
Rationale: NFPA 58 § 5.9.3 requires a shutoff valve at the container outlet for service isolation.
Q13 What is the maximum allowable pressure drop during the leak test of a new system?
Answer: No pressure drop allowed
Rationale: NFPA 58 § 6.16.3 requires the system to hold pressure with no drop during the leak
test.
Q14 When installing a 500-gallon LP gas tank, what is the minimum distance to a public way?
Answer: 25 feet
Rationale: NFPA 58 Table 6.4.1.1 requires 25 feet from containers 501–2,000 gallons to public
ways.
