Correct answer: Monthly
NFPA 10 requires a monthly visual inspection of portable fire extinguishers to confirm they remain in operable condition.
Question 5: What is the primary purpose of an automatic fire sprinkler system?
- To detect smoke and trigger evacuation alarms
- To suppress or control fire growth until firefighters arrive (Correct answer)
- To prevent all fires from igniting in a facility
- To replace portable fire extinguishers throughout a building
Correct answer: To suppress or control fire growth until firefighters arrive
Automatic sprinkler systems suppress or control fire growth, limiting damage and providing time for safe evacuation.

- 100–120°F (38–49°C)
- 135–170°F (57–77°C) (Correct answer)
- 200–250°F (93–121°C)
- 300–375°F (149–191°C)
Correct answer: 135–170°F (57–77°C)
Ordinary-temperature-rated sprinkler heads are classified at 135–170°F (57–77°C), well above normal room temperature but responsive to fire conditions.
