What happens if a conductivity test on a CO2 hose fails?

If a conductivity test on a CO2 hose fails, the appropriate response is to replace the hose. Conductivity testing is essential to ensure the operational safety of hoses used in firefighting, particularly those carrying carbon dioxide, as any failure may indicate a significant risk to safety and effectiveness.

A failed conductivity test suggests that the hose may not be able to reliably transport CO2, which is critical in fire suppression situations. Relying on a damaged or compromised hose could lead to a failure in delivering the necessary extinguishing agent and could put firefighters at risk during emergency operations.

While other options like cleaning or repairing may seem viable, they do not address potential internal damage or degradation that could compromise the hose's structural integrity. Recertifying the hose without addressing the underlying issues would also not ensure safety in future usage. Therefore, the only prudent choice in this scenario is to replace the hose entirely to maintain safety standards and operational effectiveness.
