③ Whether the parts are complete (loose, deformed, corroded and damaged);
(4) Whether the anticorrosive coating of visible parts is in good condition (slight peeling should be repaired in time, and obvious corrosion should be sent to professional departments for maintenance and pressure test);
(5) Whether the lead seal is in good condition (once it is opened, it must be refilled in accordance with the regulations, and a sealing test should be conducted to reseal it).
Regular inspection and maintenance on time: once a quarter, check whether the nozzle and nozzle are blocked, corroded or damaged, whether the rigid connection nozzle can rotate around the axis and stay at any position, whether the cart-type driving mechanism is flexible and whether there are inspection marks. Sign the check card after inspection.
Filling is carried out by a professional company recognized by the fire department.
Five, indoor fire hydrant
External inspection of fire hydrant: check whether the fire hydrant door is closed properly, whether the lock and glass are damaged, and whether the seal of fire hydrant door is intact;
Randomly cancel the detection of 10% of the total number of fire hydrants, press the fire hydrant alarm button, and the fire center should have a correct alarm display to check whether the components in the box are in good condition, whether they fall off or not, and whether the faucet in the fire hydrant leaks;
Open the fire hydrant door and take out the hose, carefully check whether there is any damage, and repair or replace it if there is; Check whether there is blackening and mildew, if there is, take it out, brush it and dry it;
