1. Which type of chimney requires the most frequent inspection due to
creosote buildup?
A. Masonry lined chimney
B. Metal factory-built chimney
C. Wood-burning chimney

compared to gas chimneys, which increases fire risk.
2. What is the primary purpose of a chimney cap?
A. Improve draft efficiency
B. Increase aesthetic appeal
C. Prevent water, debris, and animals from entering the chimney
, D. Reduce soot accumulation
Rationale: Chimney caps protect the flue from external elements that
can cause damage or blockages.
3. Which method is recommended for removing heavy creosote
deposits?
A. Vacuuming only
B. Wire brushing
C. Water washing
D. Sandblasting
Rationale: Wire brushes are designed to scrape and remove
hardened creosote from the flue walls.
4. How often should a high-use wood-burning chimney be inspected?
A. Every 5 years
B. Every 3 years
C. Annually
D. Every 2 years
Rationale: The CSIA recommends annual inspections for chimneys
