How often should water-based extinguishers be hydrostatically tested?

Water-based extinguishers should be hydrostatically tested every 5 years to ensure their structural integrity and safe functionality. This testing process involves subjecting the extinguisher to high pressure, which helps identify any weaknesses, leaks, or degradation in the material that could compromise its performance during an emergency.

The 5-year interval is based on industry standards and regulations aimed at maintaining safety and reliability for fire extinguishing equipment. Regular hydrostatic testing is essential as it provides confidence that the extinguishers will perform effectively when needed. Following this schedule helps ensure that water-based extinguishers remain compliant with safety codes and are ready for use in fire emergencies.
