Who knows the regulations for the maintenance of fire extinguishers?
The unit must strengthen the daily management and maintenance of fire extinguishers. To establish a "fire extinguisher maintenance management records", registration type, configuration quantity, location and maintenance of the management of the responsibility; clear responsibility for the maintenance of management responsibilities.
Maintenance of dry powder fire extinguisher(1) fire extinguishers should be placed in a ventilated, dry, cool and easy to use place. The ambient temperature is between -5 and +45 degrees(2) fire extinguishers shall avoid high temperature, humidity and severe corrosion, and prevent the agglomeration and decomposition of dry powder extinguishing agent.(3) check whether the dry powder is caking every half a year, and whether the carbon dioxide gas in the gas bottle leaks. Check the carbon dioxide gas cylinders, gas cylinders should be removed by stamping numerical weighing, weight and gas cylinders called out the same, such as the value of less than 7 grams or more, should be sent to the maintenance department to repair. If the system is stored, check the internal pressure indicator and indicate whether the indicator is in the green area. If the pointer is in the red area, it indicates that the internal pressure has been leaked and can not be used. The maintenance department should be sent to the maintenance department as soon as possible.(4) once the fire extinguisher is opened, it must be filled again. When it is filled again, the type of dry powder extinguishing agent can not be changed. That is, sodium bicarbonate dry powder extinguisher can not be replaced with ammonium phosphate dry powder extinguishing agent.(5) the water pressure test shall be carried out every time before or after the fire extinguisher leaves the factory for three years. The fire extinguishers, cylinders and gas cylinders shall be carried out separately during hydrostatic test. The hydraulic test pressure should be shown with the fire extinguisher on the label or the seal of the same pressure. Once the water pressure test is qualified, it can be used again.(6) the maintenance shall be handled by the specially trained personnel, and the repair and re filling shall be carried out by professional maintenance units.
The use of units to fire extinguisher maintenance at least quarterly inspections, check the contents include: the implementation of responsible maintenance duties, fire extinguisher pressure is in normal pressure range, the pin and the seal is intact, fire extinguishers can not be used for other purposes, are stable, no fire extinguisher box shall not be buried, the lock, to avoid sun exposure and strong radiation heat, the fire extinguisher is within the validity period, to check the fire extinguisher effective condition to form a "state", hanging in the fire extinguisher on express.
