In residential areas without property, the replacement of fire-fighting equipment should usually be the responsibility of the owners' Committee. If there is no owners' committee in the community or the owners' committee cannot perform its duties, the local government or relevant departments (streets, communities) may be responsible for managing and maintaining the fire control facilities and equipment in the community.

As for the expenses, unless otherwise agreed between the property and the owner, the general expenses are paid by the owner's special maintenance fund, and there is no special fund temporarily paid by the owner.

The owners' committee shall regularly inspect the fire-fighting facilities and equipment in the community, including fire extinguishers, fire hydrants and smoke detectors. If any equipment is found to be outdated or damaged, it needs to be replaced or repaired in time.

The replacement cycle of fire fighting equipment depends on its type and purpose.

The validity period of carbon dioxide fire extinguisher is 12 years.

The validity period of dry powder fire extinguisher is 10 year.

The validity period of water-based fire extinguishers is 6 years.

In addition, the replacement cycle of residential fire protection facilities is about 5 years, but this time is not fixed, depending on the degree of wear and tear of the equipment and the later maintenance. If the fire fighting equipment is well maintained, it will not be a problem if it is used for a long time; If it is not properly maintained, even after the service life, there will still be certain security risks.
