For how long must records for all non-water based fire extinguishing systems be kept on the premises?

The requirement to keep records for all non-water based fire extinguishing systems for a minimum of three years is rooted in safety regulations that aim to ensure ongoing compliance, maintenance, and readiness of fire safety equipment. This duration allows facility managers and Fire Life Safety Directors to track inspections, maintenance, and any necessary repairs or updates to the fire extinguishing systems, ensuring they remain operational when needed.

Having a three-year recordkeeping period provides a comprehensive view of the system's history, helping to identify any patterns or recurring issues. This is crucial for both the safety of the building's occupants and for meeting regulatory standards. Keeping these records also supports audits and inspections by authorities, confirming that the premises adhere to fire safety codes and regulations.

The other options of one, two, or five years do not align with the established protocols for record retention regarding non-water based fire extinguishing systems, as they either fall short of providing an adequate historical record or exceed typical requirements.
