SECTION 1: BOILER FUNDAMENTALS AND DEFINITIONS
(Questions 1-20)
1. What is the maximum allowable working pressure (MAWP) for a
low-pressure steam boiler?**
A) 10 psig
B) 15 psig
C) 30 psig
D) 50 psig
,Correct Answer: B) 15 psig
*Rationale: A low-pressure steam boiler operates at a steam or vapor
pressure of 15 psig or less. This is a fundamental definition that
appears frequently on the exam .
2. What is the maximum allowable working pressure (MAWP) for a
low-pressure hot water boiler?**
A) 100 psig
B) 125 psig
C) 160 psig
D) 200 psig
Correct Answer: C) 160 psig
*Rationale: Low-pressure hot water boilers operate at pressures not
exceeding 160 psig and temperatures less than 250°F. This is a critical
threshold to know for the exam .*
