Which statement about maintenance is true?

• A. Anyone can perform maintenance
• B. Only qualified repair personnel should perform maintenance
• C. Maintenance is optional
• D. Maintenance is prohibited

Answer: (B)

Maintenance of fire protection systems and equipment must be performed by individuals with appropriate qualifications and training. This ensures that inspections, testing, servicing, and repairs are done correctly, using proper tools and procedures, so the system remains reliable and safe. When maintenance is done by qualified personnel, potential hazards are identified and addressed, and compliance with codes and manufacturer instructions is maintained. Allowing unqualified people to perform maintenance can lead to improper work, safety risks, or system failures. Maintenance is not optional and not prohibited; it is a required, controlled activity to keep the system functioning properly. Therefore, the best statement is that only qualified repair personnel should perform maintenance.
