How Often Do Fire Extinguishers Undergo Maintenance?

In the event of a fire, fire-fighting equipment and fire extinguishers are essential and play a significant role. Fire extinguishers are essential equipment in many places, and can be put out immediately when a fire occurs. However, when using fire extinguishers, regular maintenance and inspection are also necessary to identify any abnormal issues. So how often do fire extinguishers need to be repaired? How often do fire extinguishers undergo inspection and maintenance?

How often do fire extinguishers undergo maintenance?

The frequency of fire extinguisher maintenance should be determined based on its type.

If it is a water-based fire extinguisher, it usually needs to be inspected again after being stored for three years after leaving the factory. If there are no abnormalities, it can continue to be stored and used. Next, it can be tested every two years to see if there are any quality issues. Generally, after ten years of leaving the factory, it is discarded and no longer used.

If it is a carbon dioxide fire extinguisher, it needs to be repaired five years after leaving the factory. If there are no quality problems, it can continue to be used. Then, it should be repaired every two years until it is stored for twelve years. It should be directly scrapped and no longer used in the future.

For safety reasons, the number of fire extinguishers for each maintenance cannot exceed one fourth of the total number of fire extinguishers. If it exceeds the limit, it needs to be replaced by a fire extinguisher of the same type and operating method. However, the level of the replaced fire extinguisher cannot be lower than that of the original fire extinguisher.

When using fire extinguishers, not only should regular maintenance be carried out, but also maintenance work should be done. The quality of the fire extinguisher should be checked regularly to see if there is any deformation or corrosion. If the valve body or pressure handle of the fire extinguisher is damaged, it should be repaired at a designated place.
