Final answer:
The period for keeping records for non-water based fire extinguisher systems varies by local regulations, typically ranging from several years to indefinitely. These records must be maintained on the premises for safety compliance and to prove proper maintenance.
Step-by-step explanation:
The period for keeping the inspection, testing, and servicing records of all non-water based fire extinguisher systems, which can include dry/wet chemical, foam, and carbon dioxide systems, varies depending on the local jurisdiction and regulations. Ordinarily, for accountability and safety compliance, these records should be maintained for a minimum period that may range from several years to indefinitely. It is important for facilities using such systems to adhere to their local fire code requirements and to ensure that this documentation is accessible on the premises to demonstrate proper maintenance and readiness of the fire extinguishing systems.
In addition to maintaining records, it is also crucial to know the location of safety equipment in the laboratory, such as fire extinguishers and eyewash stations, as well as to note that substances like dry-cleaning solvent are no longer recommended for use in fire extinguishers due to safety and environmental concerns.
