Who must be present for the final test of the fire extinguishing system prior to certification?

The requirement for the final test of the fire extinguishing system to be conducted in the presence of the licensee whose signature appears on the installation label ensures accountability and proper oversight over the installation process. This person has the necessary qualifications and knowledge about the system, ensuring that the test is performed correctly and adheres to safety standards. The licensee's involvement in this final testing phase confirms that they stand behind the work completed, affirming compliance with local regulations and industry standards. Having the licensee present is crucial as it provides a direct link to the installation responsibility and allows for immediate corrections or address of any issues that arise during the testing process, thereby protecting both the integrity of the system and the safety of potential future users.
