Texas Boiler Inspector Licensing Exam – Practice Test)
1. What is the primary purpose of a boiler inspector in Texas?
To ensure boilers comply with safety regulations
Rationale: The inspector’s role is to verify that boilers meet safety codes
and prevent hazards.
2. Which Texas agency regulates boiler inspections?
Texas Department of Licensing and Regulation (TDLR)
Rationale: TDLR oversees licensing, inspections, and safety enforcement
for boilers in Texas.
3. Boilers in Texas must generally be inspected how often?
Annually
Rationale: Most boilers require annual inspections unless exempt by law.
4. A boiler operating without a valid certificate of inspection is considered:
Illegal
Rationale: Operating without certification violates Texas Boiler Law.
5. The maximum allowable working pressure (MAWP) must be stamped
where?
, On the boiler nameplate
Rationale: ASME requires MAWP to be permanently stamped for
identification and safety.
6. What is hydrostatic testing used for?
To check for leaks and structural integrity under pressure
Rationale: Hydrostatic tests confirm boiler pressure vessel soundness.
7. A low-water cutoff device in a steam boiler prevents:
Boiler dry firing
Rationale: The device shuts down the boiler to prevent overheating
without water.
8. When conducting an inspection, the inspector must verify the accuracy of
which gauge?
Pressure gauge
Rationale: Pressure readings are critical to safe boiler operation.
9. The safety valve on a boiler is required to:
Release pressure before exceeding MAWP
Rationale: The safety valve is the last line of defense against overpressure
explosions.
10.Which code sets the standard for boiler construction in the U.S.?
ASME Boiler and Pressure Vessel Code
Rationale: ASME standards govern design, construction, and testing.
11.Who is responsible for scheduling required boiler inspections?
The owner or operator
, Rationale: Texas law places the duty on the owner to ensure inspections
occur.
12.Which of the following boilers is exempt from inspection in Texas?
Boilers used exclusively for heating pools at single-family residences
Rationale: Residential heating-only boilers may be exempt.
13.Internal boiler inspections require the boiler to be:
Drained, cooled, and opened
Rationale: Inspectors need safe, full access to internal components.
14.What document must be displayed in the boiler room?
Certificate of inspection
Rationale: Certificates must be posted near the boiler for proof of
compliance.
15.A hot water heating boiler must be equipped with a:
Temperature relief valve
Rationale: Relief valves protect against excessive temperature and
pressure.
16.Before re-entering service after repairs, a boiler must:
Be re-inspected by a licensed inspector
Rationale: Repairs require verification to ensure safe operation.
17.In Texas, inspectors must hold a license issued by:
TDLR
Rationale: Only TDLR-licensed inspectors are authorized to perform
inspections.
, 18.If a boiler fails inspection, the inspector must:
Issue a report and notify the owner of required corrections
Rationale: The inspector ensures corrective action before re-certification.
19.A boiler certificate of inspection is valid for:
12 months
Rationale: Most Texas boiler certificates expire annually.
20.The blowdown valve is used for:
Removing sediment and controlling boiler water quality
Rationale: Blowdown prevents scale and corrosion.
21.When inspecting a safety valve, the inspector checks:
Capacity, set pressure, and condition
Rationale: Safety valves must function correctly to protect the vessel.
22.The main cause of boiler explosions historically has been:
Low-water conditions
Rationale: Lack of water causes overheating and vessel failure.
23.A pressure relief device must be tested:
At least annually
Rationale: Regular testing ensures proper operation.
24.Inspectors must verify that boiler operators are:
Qualified and trained
Rationale: Operator knowledge reduces risks.
