flammable gas storage and air-conditioning equipment or
ventilation intakes?
A) 10 feet

, Rationale: "Neck leakers" is the common industry term for leaks
occurring at the junction where the valve is attached to the
cylinder body.

gas containers be removed from the site?
A) After the job is 50% complete
B) Every night (overnight storage is not allowed)
C) Only when they are empty
D) Every Friday evening
Rationale: Citywide permits do not allow for overnight storage;
containers must be brought in the morning and removed daily.
10. In the NFPA 704 diamond sign, which color
represents the "Flammability" hazard?
A) Blue
B) Red
C) Yellow
D) White
Rationale: The red quadrant of the NFPA 704 diamond indicates
the degree of flammability hazard.
11. At construction sites, what is the maximum quantity of
flammable gas allowed per floor?
A) 500 SCF
B) 1,500 SCF
C) 3,500 SCF
D) 5,000 SCF
Rationale: Construction sites have specific limits of 3,500 SCF per
floor, not to exceed 15,000 SCF for the entire building.
12.Which type of supervision is required for the handling
and use of flammable gases?
A) General supervision
B) Personal supervision
C) Indirect supervision
D) Remote supervision
Rationale: The handling and use of these gases require the G-98
holder to be physically present on-site (personal supervision).
13.Compressed gas containers must not be exposed to
temperatures exceeding:
A) 100°F
, B) 125°F
C) 150°F
D) 212°F
Rationale: Cylinders must be kept away from excessive heat to
prevent pressure build-up; 125°F is the standard limit for storage.
14.Incompatible materials must be separated by a
noncombustible partition extending how far above the
stored material?
A) 6 inches
B) 12 inches
C) 18 inches
D) 24 inches
Rationale: Partitions used for separation must extend at least 18
inches above and to the sides of the containers.
15. A Class B fire extinguisher is best used for which type of
fire?
A) Paper and wood
B) Flammable liquids or gases
C) Electrical equipment
D) Combustible metals
Rationale: Class B extinguishers are designed for fires involving
flammable liquids, oils, and gases.
16.How far must flammable gas storage be from open flames
or other ignition sources?
A) 10 feet
B) 15 feet
C) 20 feet
D) 25 feet
Rationale: A minimum clearance of 25 feet is required from all
ignition sources like open flames or electrical equipment.
17. What does "SCF" stand for in gas measurement?
A) Simple Cubic Feet
B) Standard Cubic Feet
C) Static Compressed Flow
D) Super Charged Fuel
Rationale: SCF is the standard unit of measurement for gas
volume at a specific temperature and pressure.
