Where should the test information for carbon dioxide hose assemblies that pass the conductivity test be recorded?

The test information for carbon dioxide hose assemblies that pass the conductivity test should be recorded on the hose assembly itself. This is important because maintaining a clear and accessible record directly on the hose assembly helps ensure that anyone inspecting or using the equipment can easily verify that it has met the necessary safety standards.

Recording this information on the hose assembly allows for consistent tracking of maintenance and testing history, which is crucial for compliance with safety regulations. In the case of a carbon dioxide extinguisher, the hose assembly is a critical component that needs to be regularly checked for functionality and safety. Having the test information available helps to prevent any potential mix-ups or assumptions about the condition of the assembly and ensures that it can be used safely in an emergency situation.

The other options, while potentially relevant to fire extinguishers overall, do not serve as practical locations for recording this specific test information. The fire extinguisher and the carrying handle may not provide a suitable or visible location for this detail, while placing information on the discharge lever could obstruct its functionality or clarity when in use. Thus, recording on the hose assembly is the best practice for maintaining safety and regulatory compliance.
