    (5) Keep the work area clean and tidy, and promptly remove dangers caused by waste wire, waste film and other obstacles. Before starting the equipment, check whether the protective covers and other safety facilities are intact and whether the emergency stop switch is effective.

    (6) Develop measures for specific equipment to prevent rollers and high-speed moving parts from pinching hands and mechanical injuries, as well as on-site treatment and medicines when accidents occur. Develop measures to prevent burns in high-temperature places such as machine heads and ovens, as well as on-site treatment and medicines when accidents occur.

    (7) The joints at the heating coil must be covered with porcelain caps to prevent electric shock. During normal operation, all electrical control box and distribution cabinet doors must be closed tightly. Non-professional electricians are not allowed to perform maintenance on electrical systems.

  3. Equipment security
  4. Develop detailed rules for safety inspections before starting the machine.

    The screw must not be run without material or load to avoid grinding the screw.

    After the temperatures of the machine head and barrel reach the set temperature, they must be kept warm for 1 hour before starting the extruder to avoid twisting the shaft.

    The speed regulator using an electromagnetic speed-regulating motor must follow the procedure of starting the motor→turning on the speed-regulating power supply→slowly adjusting the speed. When stopping, turn the speed regulator knob to the "0" position.

    Never allow tools, metal or other foreign objects to fall into the hopper.

    The extruder head must not operate under overpressure, and the filter should be replaced in time to avoid damage to the thrust bearing and the collapse of the large flat filter, injuring people and equipment.
