Which party is responsible for servicing and testing fire extinguishers and fixed fire protection systems?

Fire protection system maintenance is the correct choice because it specifically refers to the ongoing service, testing, and maintenance of fire extinguishers and fixed fire protection systems. This maintenance ensures that these systems function effectively when needed and meet the necessary regulatory and safety standards.

Professionals in fire protection system maintenance are trained to conduct regular inspections, testing, and repairs. They are knowledgeable about the specific requirements for different types of fire protection equipment, including portable extinguishers and fire suppression systems, ensuring compliance with local codes and standards.

The other parties mentioned, while they may play roles in the broader context of fire safety, do not typically handle the servicing and testing of fire protection equipment directly. Fire department personnel primarily focus on emergency response operations and firefighting rather than routine maintenance. Emergency management services deal with disaster preparedness and response, while insurance agencies may assess risks and offer coverage but do not provide direct maintenance services for fire protection systems.
