1. Fire extinguishers in transport and storage, should avoid pouring, rain, exposure, strong radiation and contact with corrosive substances.
2. The ambient temperature of the fire extinguisher shall be within-10-45 Shan range.
3. Fire extinguishers should be kept dry and ventilated to prevent damp corrosion of the cylinder. Should avoid sun exposure and strong radiation heat, so as not to affect the normal use of fire extinguishers.
4. The fire extinguisher shall be inspected periodically according to the requirements and inspection cycle specified by the manufacturer.
5. Once opened, the fire extinguishers, even if the spray is not much, it must be required to carry out a refill installed by the Professional maintenance department according to the requirements and methods specified by the manufacturer, do not arbitrarily change the variety of extinguishing agent, weight and driving gas pressure.
6. Fire extinguishers by functional inspection found that there are problems, must be entrusted with maintenance qualification maintenance units for maintenance, replacement of damaged parts, cylinders to carry out hydrostatic test, refill the extinguishing agent and driving gas. The maintenance unit must strictly implement the fire extinguisher scrap system. Fire extinguishers every five years and each reload before the main pressure components, such as the head, cylinder and so should carry out hydrostatic test, the qualified person can continue to use. After the test should be timely drying, and check the inner wall, should not be obvious corrosion. The water pressure test is unqualified and cannot be repaired using welding method.
7. The fire extinguishers repaired by the maintenance department shall be marked with the approval of the FSD and note the name of the maintenance unit and the date of maintenance.
8. Fire extinguishers, whether used or not used, from the production date (each with a fire extinguishers on the barrel of the production date) to calculate, to reach the required maintenance years after the maintenance unit must be sent to repair, to reach the scrap period of time must be scrapped, maintenance of the cylinder by water pressure test unqualified fire extinguishers must also be scrapped.
9. Management and maintenance of fire extinguishers must be strengthened. To establish "fire extinguishers", the registration type, the number of configuration, the location and maintenance of the responsible person to manage;
10. Management to the maintenance of fire extinguishers at least quarterly inspection, inspection content includes: responsible for the implementation of the responsibility of maintenance, fire extinguishers pressure value is in the normal pressure range, the insurance pin and seals are intact, fire extinguishers can not be used for its use, placed firmly, no buried pressure, fire extinguisher box should not be locked, to avoid sun exposure and strong radiation heat, fire extinguishers in the period of validity, etc., to check the status of the fire extinguishers to make a "fire extinguisher inspection Record", archived to facilitate verification.
