How often should a carbon dioxide extinguisher be maintained?

Carbon dioxide extinguishers require maintenance every 5 years to ensure they function properly when needed. This maintenance period helps identify any issues that could impede the extinguisher's effectiveness, such as loss of pressure or damage to the unit. During this maintenance check, a trained professional will inspect the extinguisher for signs of wear, verify its pressure gauge, and conduct any necessary repairs or recharges to keep it operational.

Regular maintenance is crucial because carbon dioxide extinguishers are often used for specific types of fires, such as electrical fires and those involving flammable liquids. If they are not regularly maintained, there is a risk that they may fail during an emergency, which could result in dangerous situations. By adhering to the 5-year maintenance schedule, users can ensure the reliability and safety of their carbon dioxide extinguishers.
