A fire extinguisher is an essential safety tool in homes, offices, and industrial settings.

In this article, we will discuss the signs that indicate a need for replacement, best practices for disposing of old extinguishers, and how to choose a suitable replacement.
When to Replace Your Fire Extinguisher
1. Expired Lifespan
- Most fire extinguishers have a lifespan of 5 to 15 years, depending on the type and manufacturer’s guidelines.
