The Fire Extinguisher ABC Seal indicates that the extinguisher is rated for use on three types of fires: Class A (ordinary combustibles like wood and paper), Class B (flammable liquids), and Class C (electrical fires). The seal ensures that the extinguisher has not been tampered with or used, maintaining its reliability. This rating makes ABC extinguishers suitable for various environments, including homes and workplaces. Regularly check the seal and the extinguisher's condition, including pressure and accessibility. Apart from this, the Fire Extinguisher ABC Seal can be availed at very reasonable rates.
