During which interval are internal exams required for stored pressure loaded stream fire extinguishers?

Stored pressure loaded stream fire extinguishers require internal exams every year to ensure they are functioning safely and effectively. This annual inspection process is critical, as it allows technicians to check for any deterioration, leaks, or other issues that could impact the extinguisher's performance in an emergency. Regular internal examinations help maintain the integrity of the extinguisher and ensure compliance with safety regulations and standards.

In contrast, longer intervals might apply to different types of inspections or maintenance checks, but for stored pressure extinguishers specifically, the annual internal examination is considered best practice to ensure that they are always ready for use.
