How often do non-rechargeable fire extinguishers need to be replaced?

Non-rechargeable fire extinguishers, often referred to as one-time use extinguishers, have a specific lifespan that is critical to ensuring they function properly when needed. The correct replacement timeline for these extinguishers is every 12 years. This period is established to ensure the integrity of the extinguisher can be maintained, as materials can degrade over time, and the effectiveness of the extinguishing agent can diminish.

After 12 years of service, even if the extinguisher appears to be in good condition visually, specific components may wear out or the agent may not perform as expected in an emergency situation. Adhering to this replacement schedule is crucial for safety, as relying on an outdated extinguisher might compromise firefighting efforts during a critical moment.

The other potential timelines presented do not align with established safety regulations and standards for non-rechargeable extinguishers, which emphasize the 12-year requirement to ensure a safe and effective firefighting tool.
