What is the average lifespan of a typical portable fire extinguisher?

The average lifespan of a typical portable fire extinguisher is generally considered to be between 5 to 15 years. This duration accounts for both the integrity of the extinguisher's components and the effectiveness of the extinguishing agent it contains. Over time, fire extinguishers can experience wear and tear, diminishing their ability to function properly in an emergency.

Regular maintenance and inspections are critical, as they help ensure that the extinguisher remains in good working condition throughout its lifespan. After the 5 to 15 year range, while some extinguishers may still function adequately, the recommendation is often to replace them to ensure the highest level of safety. This timeframe helps users and safety professionals understand when to schedule replacements or more extensive inspections to ensure that fire protection equipment is reliable and effective.
