Non-compliant aspects of lined fire hoses directly compromise the safety of firefighting and rescue operations. Failure to meet test pressure and minimum burst pressure requirements can cause the hose to rupture under rated working pressure; this not only instantly cuts off the water supply at the fire scene but also creates debris that can injure firefighters, potentially leading to the failure of the firefighting effort. Inadequate adhesion strength can result in leakage and reduced pressure resistance, potentially causing delays that miss the critical window for extinguishing the fire.
Batches failing to meet standards are occasionally identified during supervisory spot checks. In 2020, the Shenzhen Municipal Administration for Market Regulation conducted spot checks on 12 batches of lined fire hoses and found one batch to be non-compliant due to issues with adhesion strength.
