2. Box shape and cleanliness of fire extinguishers.
3. Inspection of pressure indicator: A pressure indicator should be installed, and the surface of the pressure indicator of dry powder fire extinguisher should be marked with "F". Whether the pressure indicator pointer is in the green area.
4. Inspection of injection hose
A fire extinguisher with a fire extinguishing dose greater than 3Kg(L) shall be equipped with a spray hose with a length of 400mm, excluding the connectors or nozzles at both ends of the spray hose.
5. Inspection of insurance institutions
Fire extinguishers should be equipped with safety devices. The safety device can be a safety pin or other structure with the same function. The safety pin should be sealed with lead or plastic tape, which is disposable. If the lead seal or plastic tape seal on the safety pin falls off or breaks, it means that the fire extinguisher has been used.
6, check the logo
Marks, also known as decals, are usually attached to the surface of cylinders with printed self-adhesive stickers. The inspection of the sign is mainly to check whether the content of the sign is correct and complete. The inspection contents of the identification shall include the name, model, fire extinguishing level, use temperature range, quantity and name of driving gas, name of manufacturer, use method, etc.
7. Identification on the fire extinguisher: MF(L) means: fire extinguisher, dry powder fire extinguishing agent, dry powder fire extinguishing agent feature code (L stands for phosphate ingot salt dry powder fire extinguishing agent), and the weight of the filled dry powder fire extinguishing agent is 8kg.
8. Check whether the cylinder is permanently marked.
9. Whether the safety bolt is loose or damaged.
10, whether the pressure gauge pointer reaches the yellow area, and if so, it needs to be replaced.
1 1. Whether the fire extinguisher nozzle is blocked or damaged.

Matters needing attention
1. During transportation and storage, fire extinguishers should be protected from inversion, rain, sunlight, strong radiation and contact with corrosive substances.
2. The storage environment temperature of fire extinguishers should be within the range of-10-45℃.
3. The place where the fire extinguisher is placed should be kept dry and ventilated to prevent the cylinder from being corroded by moisture. Sun exposure and strong radiant heat should be avoided to avoid affecting the normal use of fire extinguishers.
4. If there is a problem with the fire extinguisher through functional inspection, it must be repaired by a qualified maintenance unit, and the damaged parts and gas cylinders should be replaced for hydrostatic test, and the fire extinguishing agent and driving gas should be refilled. Maintenance units must strictly implement the fire extinguisher scrapping system.
Every five years and before refilling, the main pressure parts of the fire extinguisher, such as the head and cylinder, should be subjected to water pressure test, and only those that pass the test can continue to be used. After the test, the inner wall shall be dried and inspected in time, and there shall be no obvious corrosion. If the water pressure test is unqualified, welding repair is not allowed.
5. The fire extinguishers repaired by the maintenance department shall be approved by the fire supervision department, and the name and maintenance date of the maintenance unit shall be indicated.
6. Fire extinguishers, whether used or unused, must be sent to the maintenance unit for maintenance after reaching the specified maintenance period from the production date (the production date is on the cylinder of each fire extinguisher). Those that reach the scrapping period must be scrapped, and those that fail to pass the hydrostatic test during maintenance must also be scrapped.
7, management office must strengthen the daily management and maintenance of fire extinguishers. Establish a "fire extinguisher account", and register the type, configuration quantity, installation location and the person responsible for maintenance and management; Clarify the responsibilities of the person responsible for maintenance management.
