Introduction
,The TDLR Boiler Installation/Inspection Examination assesses the knowledge and skills required for safe boiler
installation, operation, and inspection in Texas. This comprehensive multiple-choice assessment evaluates foundational
theory, applied professional knowledge, regulatory compliance, and real-world decision-making. Questions emphasize
practical application of ASME Code requirements, Texas Administrative Code Chapter 65 provisions, and industry best
practices for boiler safety. Candidates must demonstrate competency across boiler types, combustion systems, water
treatment, safety devices, and inspection procedures. The examination includes scenario-based questions designed to
test critical thinking and professional judgment in authentic field situations. A passing score demonstrates readiness for
professional responsibilities in boiler inspection and installation.
SECTION ONE: QUESTIONS 1–50
Question 1
What is the primary purpose of a safety relief valve on a boiler?
A. To regulate fuel pressure
B. To maintain the water level
C. To prevent excessive boiler pressure
D. To control combustion air
,🟢 Correct Answer: C. To prevent excessive boiler pressure
🔴 Explanation: A safety relief valve opens automatically when pressure reaches its set limit, preventing dangerous
overpressure conditions that could damage the boiler or cause an explosion hazard.
Question 2
Before beginning an inspection of a boiler, the inspector should first verify that:
A. The boiler is operating at maximum capacity
B. The boiler can be safely accessed and inspected
C. The burner is firing continuously
D. The pressure gauge has been removed
🟢 Correct Answer: B. The boiler can be safely accessed and inspected
🔴 Explanation: Safety must be verified first, including equipment isolation, lockout procedures, and safe access,
before any inspection work begins.
Question 3
Which component indicates the pressure inside a steam boiler?
, A. Thermocouple
B. Sight glass
C. Aquastat
D. Pressure gauge
🟢 Correct Answer: D. Pressure gauge
🔴 Explanation: A pressure gauge provides direct indication of internal boiler pressure, allowing comparison of
actual operating pressure with allowable limits.
Question 4
What is the main danger of operating a steam boiler with an extremely low water level?
A. Excessive condensation
B. Reduced electrical voltage
C. Overheating of boiler heating surfaces
D. Increased water hardness
