② Check and clean the magnetic separator regularly, at least once a day.
③ In order to avoid heat generation, it is necessary to regularly check the functions of all main shafts and
bearings, at least once a week, and to fill up with lubricant on regular basis.
(3)Electric apparatus
Regularly check the electric apparatus and articles, and special attention should be paid to the
following points:
①Do not use any flashlights and other lamps without shielding or explosion-proof glass.
②Do not use any cable extension or electric heater.
③Repair or replace the electric apparatus and equipment immediately if any failure occurs.
④Do not install cables directly on the floor.
⑤ Cut off the power supply of the machine after work.
⑥Assign an electrician to check the insulation, at least once a year, of all the power lines of
electric network according to relevant regulations.
(4)Smoking and welding
①Smoking is forbidden. Such stipulate is applicable to all workers and staff of the enterprise
as well as guests, customers, outcomers, and drivers visiting the factory.
②If the tools such as welding machine or soldering lamp (flame soldering lamp) etc. are
required for repair or installation, do as best as possible to arrange the work in a special
workshop or on a designated site.
③For occasional welding or the like work directly in production area or warehouse, submit
applications in writing to a concerned supervisor in advance for written approval. Only can the
above mentioned operations be carried out when special safety measures have been taken,
such as laying water soaked canvas or special fire-resistent canvas with fire extinguishers
standing by. After completion of the operation, monitor the welding site and the surrounding
area for at least 10 hours.
④The torch cutting sparks are very dangerous.They can travel across through the narrow
clearance of walls and drop downstairs or to the next rooms, or even fly off 10m away in
distance. If the sparks drop in dusts, fire accidents may occur at any time.
⑤Welding is prohibited on a running conveyor. If the welding work is a must, shut down the
conveyor first, and then make a thorough cleaning and isolate both sides of the welding site
tightly with materials like mineral wool to avoid connecting with other conveying devices, silos
or tanks. If the chutes or conveying pipes require welding work, disassemble them or
disconnect their lower ends with silo or tank and seal them to avoid welding sparks entering
the conveying pipes or silos.
(5)Effect of static electricity
①To ensure the safety of electric circuits and avoid explosion resulted from spark discharge.
②The paint coat at the electric connections must be removed.
