Safety precautions during electrolysis production

(1) Electrolysis production personnel must undergo three-pole safety education before entering the workshop and being allowed to operate.
(2) When using iron tools in the electrolysis plant, attention should be paid to the magnetic field to prevent accidents.
(3) All iron tools in contact with electrolyte must be preheated before use.
(4) It is prohibited to sit, lie down, rest or play in the aisles of the workshop. It is prohibited to rest or sit on the trough cover
(5) It is prohibited to throw tools and waste downstairs or outside the workshop. When tools fall, you must immediately check whether they are connected to the electrolytic tank, busbar, and ground. Remove them in an emergency.
(6) When working on the electrolytic cell, it is prohibited to put your feet on the electrolyte shell or anode carbon block to avoid burns.
(7) The materials added to the tank must be confirmed to be dry before being added.
(8) When replacing the anode, the Tathagata effect will stop the operation immediately. After the treatment is extinguished, continue the operation.
(9) Make an aluminum opening. When measuring the level, you should wear glasses and a mask to prevent burns from electrolyte splashes.
(10) Before changing poles, personnel must wear labor protection equipment before entering the pole changing site.
(11) When replacing iron sheets, it is strictly forbidden to bring the iron sheet and column busbars close to each other to avoid serious accidents.
(12) The pole changer directs the crane to lift the remaining pole and confirms that the spreader is hanging on the guide rod to prevent accidents caused by falling when lifting out.
(13) When lifting the anode, you must have sharp eyesight and quick hands to remove the pieces from the remaining anode to prevent large pieces from falling into the slot and affecting the speed and quality of pole changing.
(14) When the residual pole is lifted out, other unrelated personnel should stay away from the residual pole to avoid burn accidents.
(15) When placing the residual electrode, the electrolyzer should command the overhead crane correctly and confirm that it is placed stably before removing the spreader.
(16) The shoveling personnel must wear masks and other labor protection before they can work. It is forbidden to stand on the edge of the trough and work directly on the board.
(17) Personnel who fish out the pieces must steadily, accurately and quickly fish out the large and small noodle shell pieces in the tank, and grasp the strength and direction when fishing to avoid burns.
(18) The deputy squad leader must use a rake to touch the bottom of the furnace to prevent any lumps from falling into the bottom of the tank, so as not to cause sedimentation and cause hidden dangers to the future operation of the tank.
(19) Command the crane to install the new pole. If the new pole is wet, the person changing the pole should stay away and dry the anode before placing it in the tank to avoid electrolyte splashing and hurting people.
(20) Before cleaning the anode, confirm whether the anode to be cleaned is placed smoothly. If it is unstable, it will not be cleaned.
(21) Wear complete labor protection before cleaning to avoid burns from flying hot noodle shells
(22) Do not stand on the hot noodle shell when cleaning. People on the opposite side must stay away to prevent the cleaned noodle from flying out and causing burns.
(23) When smashing blocks, you should be careful and use even force to avoid accidents.
(24) The cleaned carbon rings must be detected. The cleaned noodle shell blocks should be placed in designated places and must not be scattered on the ground to block walking roads.
(25) During maintenance, smash the replaced large pieces. Ping the edges of the three poles with empty adjacent poles. It is strictly forbidden to stack large pieces on the anode or adjacent poles.
(26) After replacement and maintenance, clean up the site and place the iron sheet in the designated location. Do not leave it randomly to affect on-site management.
(27) Do not leave the pole-changing tools such as hooks, rakes, drills, etc. that have just been harvested, outside the infrared light next to the tank body, which will affect the movement of the aluminum pulling truck.
(28) After maintaining the anodes, all poles that are replaced during the shift should be inspected to improve the quality of maintenance.
