What is the hydrostatic testing interval for carbon dioxide fire extinguishers?

The hydrostatic testing interval for carbon dioxide fire extinguishers is indeed 5 years, rather than 12 years. It's essential to understand that hydrostatic testing is a crucial safety measure designed to ensure that extinguishers can withstand pressure without leaking or rupturing. This testing helps maintain the integrity of the extinguisher over time, as they can be subject to wear and other factors that may compromise their safety and functionality.

While various types of fire extinguishers may have different testing intervals, carbon dioxide ones are specifically mandated to undergo hydrostatic testing at a maximum of every 5 years per industry standards. This shorter interval reflects the nature of the gas and the potential risks involved if an extinguisher doesn't function properly during an emergency.

Maintaining a regular schedule for hydrostatic testing is essential for ensuring that each fire extinguisher remains in optimal working condition. Users should reference the local fire codes or standards to confirm the specific requirements applicable in their region, as regulations can vary.
