Maintenance and Repair of Fire Protection Systems
CSLB weights Maintenance and Repair at about 9% of the C-16 exam: inspecting and troubleshooting, repairing, and maintaining fire protection equipment. This page is a short survey; the PrepPass C-16 Fire Protection study guide teaches the section with worked examples, chapter quizzes and a full practice exam at CSLB's weights.
Inspect, test and maintain
Inspection needs no license; testing and maintenance of automatic fire extinguishing systems is performed by those licensed under Health and Safety Code 13196.5. Records are kept five years after the next required event.
Repair and impairments
A required system that is out of service is an impairment: notify the fire department and fire code official immediately and post a fire watch where required.
Keep it operating
Maintenance keeps a system operative at all times, and tampering with a required system is unlawful except for listed purposes.
