Updated for Current Year | Stuvia-Ready Format
EXAM TYPE: 661-LA Second Class Stationary Boiler Operator Certification
REGULATORY AUTHORITY: City of New Orleans – Board of Examiners of Steam Boilers
(pursuant to LA R.S. 33:4814)
CODE REFERENCES: ASME Boiler and Pressure Vessel Code Section I, ASME CSD-1,
National Board Inspection Code (NBIC), NFPA 85
QUESTION 1
What is the maximum allowable working pressure (MAWP) range typically covered by a
Second Class Stationary Boiler license in New Orleans?
A) 0-15 psi
B) 16-100 psi
C) 101-150 psi
D) Over 150 psi
C) 101-150 psi
,Rationale: Second Class certification typically covers boilers operating between 101-150
psi, though exact ranges may vary by local ordinance. First Class licenses cover higher
pressure systems .
QUESTION 2
Which governing body administers the 661-LA Second Class Stationary Boiler Operator
Certification in New Orleans?
A) Louisiana Department of Environmental Quality
B) City of New Orleans Board of Examiners of Steam Boilers
C) ASME International
D) National Board of Boiler and Pressure Vessel Inspectors
B) City of New Orleans Board of Examiners of Steam Boilers
Rationale: The New Orleans Board of Examiners of Steam Boilers administers the exam
pursuant to Louisiana Revised Statutes §33:4814. Municipalities with populations over
50,000 may regulate stationary steam boilers and certify engineers .
QUESTION 3
Where must a Second Class Stationary Boiler Operator certificate be posted after it is
issued?
A) At the operator's home address
B) Conspicuously in the engine room where the boilers are operated
C) At the company's main office
D) On the boiler itself
B) Conspicuously in the engine room where the boilers are operated
Rationale: Louisiana law requires that the certificate be posted conspicuously in the engine
room where the boilers are operated .
,QUESTION 4
How often must a Second Class Stationary Boiler Operator certificate be renewed in
New Orleans?
A) Every 6 months
B) Annually
C) Every 2 years
D) Every 5 years
B) Annually
Rationale: Certificates must be renewed annually to remain valid. This is a municipal
requirement under the City of New Orleans stationary engineer licensing program .
QUESTION 5
What is the minimum education and experience requirement to sit for the New Orleans
Second Class Stationary Boiler Operator exam?
A) High school diploma or equivalent plus documented experience
B) No formal education required
C) Associate degree in engineering
D) 5 years of experience with no education requirement
A) High school diploma or equivalent plus documented experience
Rationale: Candidates must demonstrate sufficient knowledge and typically need a high
school diploma or equivalent plus documented experience operating boilers under
supervision .
QUESTION 6
According to ASME Section I, what is the minimum required pressure for a hydrostatic
test of a new steam boiler?
A) Maximum Allowable Working Pressure (MAWP)
B) 1.25 × MAWP
, C) 1.5 × MAWP
D) 2.0 × MAWP
C) 1.5 × MAWP
Rationale: ASME Section I (Power Boilers) mandates that the hydrostatic test pressure be at
least 1.5 times the MAWP. This ensures the vessel has an adequate safety margin above its
design limits and verifies leak tightness at stress levels exceeding normal operation .
QUESTION 7
What is the minimum and maximum size for a safety valve per ASME code for boilers?
A) Minimum 1/2" and Maximum 4"
B) Minimum 3/4" and Maximum 4 1/2"
C) Minimum 1" and Maximum 5"
D) Minimum 1/2" and Maximum 3"
B) Minimum 3/4" and Maximum 4 1/2"
Rationale: ASME code specifies a minimum safety valve size of 3/4 inch and a maximum
of 4 1/2 inches for boilers .
QUESTION 8
What is the maximum size safety valve that can be attached by threaded connection?
A) 2 inches
B) 3 inches
C) 4 inches
D) 4 1/2 inches
B) 3 inches
Rationale: Safety valves over 3 inches or when used for pressure in excess of 15 psi must
be attached by flange or welded connection .
