At which intervals must fire extinguishers be checked for usability?

Fire extinguishers must be checked for usability every 12 months in Germany. This regular inspection ensures that the device functions correctly in case of an emergency. Having annual checks is important for safety, as fire extinguishers can lose pressure or become damaged over time, making them unreliable if not properly maintained. By following the 12-month interval, you comply with the legal requirement and help guarantee readiness in case of fire.
