Total Questions: 82
Time Allowed: 180 minutes (3 hours)
Passing Score: 70% (58 correct)
Topics Covered: Safety, Blueprint Reading, Pipefitting Math, Welding & Joining,
Valves & Fittings, Code Compliance (ASME/ANSI), Rigging & Lifting, Testing &
Inspection.
Section 1: Pipefitting Safety & OSHA Compliance (10 Questions)
1. According to OSHA 1926.756, what is the maximum allowable gap between the
leading edge of a walking/working surface and the wallwhen using a guardrail
system?
A) 14 inches
B) 18 inches
C) 24 inches
D) 12 inches
Rationale: OSHA requires that gap not exceed 18 inches to prevent falls through
the opening.
2. When hydrotesting a piping system at 500 psi, the minimum distance for
barricading the test area is:
A) 25 ft
,B) 50 ft
C) 100 ft
D) 150 ft
Rationale: For pressures > 250 psi, barricade radius = 100 ft minimum per ASME
B31.3, para. 345.8.
3. The maximum safe working load (SWL) of a worn 5/8-inch wire rope sling
(6x19) with a basket hitch is:
A) 5,000 lbs
B) 7,500 lbs
C) 10,000 lbs
D) 12,500 lbs
Rationale: Basket hitch doubles strength, but wear reduces rating. Standard SWL
for new 5/8” wire rope ~ 12,000 lbs; subtract 1/3 for wear = 8,000 lbs (closest is
7,500 lbs).
4. Which confined space hazard is most common during pipe welding in a newly
fabricated vessel?
A) Oxygen deficiency
B) Argon displacement
C) Methane accumulation
D) Hydrogen sulfide
Rationale: Argon shielding gas is heavier than air and can accumulate in low
points, displacing oxygen.
5. What color is the fire hydrant top if the available flow is between 1,000–1,499
GPM?
A) Red
B) Orange
C) Green
D) Blue
Rationale: NFPA 291: Green = 1,000–1,499 GPM.
6. A pipefitter must wear a Class 2 hard hat when:
A) Working above 6 ft
B) Exposed to electrical hazards below 20,000 volts
, C) Welding overhead
D) Using a 4 lb sledge
Rationale: Class 2 hard hats are dielectric (tested to 20,000V). Class 1 for impact
only.
7. What is the minimum number of lanyard attachment points required on a full-
body harness per ANSI Z359.11-2024?
A) One (dorsal)
B) Two (dorsal & sternal)
C) Three
D) One (sternal only)
Rationale: 2024 revision requires both a dorsal (back) and a sternal (chest) D-ring
for fall arrest and rescue.
8. If a process pipe contains hot sulfuric acid, the first step before breaking a flange
is:
A) Apply torque wrench
B) Isolate, depressurize, and verify with bleed
C) Vent through a bleeder valve
D) Call a supervisor
Rationale: Must follow LOTO – isolate, depressurize, verify zero energy via
bleed/vent.
9. A scaffold plank extending over an edge must extend past the support by at least:
A) 4 inches
B) 6 inches
C) 12 inches
D) 18 inches
Rationale: OSHA 1926.451(b)(6): Minimum 6 inches, maximum 12 inches
overhang.
10. The permissible exposure limit (PEL) for respirable crystalline silica during
pipe cutting (8-hour TWA) is:
A) 10 µg/m³
B) 50 µg/m³
C) 100 µg/m³
D) 250 µg/m³
