Sample Questions

Question 1
According to NFPA 211, what is the minimum clearance required between a factory-built fireplace chimney and combustible framing members?
2 inches on all sides
1 inch on all sides
3 inches at the top, 0 inches at the sides
No clearance required if the chimney is listed
Question 2
A CMI inspector observes a masonry chimney with a clay tile flue liner that has multiple cracks and mortar joint spalling. What is the primary life-safety concern?
Combustion gases including carbon monoxide can migrate into the living space through liner defects
Reduced draw and slower fire start-up
Increased creosote accumulation on the exterior
Thermal bridging and heat loss through the chimney wall
Question 3
The EPA action level for radon in indoor air is 4.0 pCi/L. A post-mitigation test result shows 3.8 pCi/L. What should the CMI communicate to the client?
The result is below the EPA action level but still above the EPA-recommended goal of 2.0 pCi/L; further reduction may be warranted
The mitigation system succeeded fully; no further action is needed at any future date
The result is dangerously high and the home is uninhabitable
Post-mitigation testing is only valid if conducted during heating season
Question 4
When inspecting an electrical service panel, NEC 110.26 requires a minimum working space in front of the panel of:
30 inches wide, 3 feet deep, and 6 feet 6 inches high
24 inches wide, 2 feet deep, and 6 feet high
36 inches wide, 3 feet deep, and 6 feet high
18 inches wide, 3 feet deep, and 6 feet 6 inches high
Question 5
A CMI observes that the gas piping inside a residence is not bonded to the electrical grounding system. According to NEC 250.104(B), this is a deficiency because:
Interior metal gas piping can reach a dangerous voltage potential in a fault condition without bonding, creating an electrocution risk
Gas piping must be bonded to prevent static discharge from the gas flow
Bonding equalizes gas pressure throughout the distribution system
NEC 250.104(B) only applies to exterior gas piping, so interior piping has no bonding requirement
