According to the guidelines set by the Bureau of Indian Standards (BIS), specifically IS 2190, the recommended frequency for refilling fire extinguishers is once every year. This standard is crucial to ensure the optimal functioning and reliability of these life-saving devices. Regular refilling prevents the possibility of corrosion or leakage, which can compromise their effectiveness during emergencies. It also allows for a thorough inspection of the extinguisher’s components, including the gauge, hose, and nozzle, to identify any damages or wear and tear. Additionally, it is essential to refill fire extinguishers after any discharge, even if it was only a partial discharge, to guarantee their uninterrupted performance. Adhering to the prescribed refilling frequency ensures the readiness of fire extinguishers and enhances fire safety measures in various settings, be it residential or commercial.
