1 Purpose: To regulate employee behavior, standardize operations, and ensure the safety of personnel and equipment. 2 Scope Applicable to the safe operation and routine maintenance of belt conveyors. 3 Risk identification: Struck by objects, mechanical injuries, electric shock, fire, other injuries (olfactory disorders). 4 Protective equipment: Safety helmets, protective clothing, safety shoes, dust masks. 5 Operating procedures: 5.1 Before starting up: 5.1.1 Ensure that there are no people or obstacles around the equipment, and that all safety protection measures are in good condition. 5.1.2 Check whether the conveyor belt, reducer oil level, cleaners, and skirt rubber of the material chute are normal, and whether there is any loosening of fasteners. 5.1.3 Ensure that protective devices such as the belt conveyor pull cords, deviation detection systems, emergency stop switches, and speed switches are in good condition. The pull cords and emergency stop switches must not reset automatically; manual reset is required. 5.1.4 Before starting the machine, on-site personnel, workers from upstream and downstream processes, and central control operators must all give their confirmation before the machine can be started. 5.2 During operation 5.2.1 Contact with moving parts is prohibited. It is strictly forbidden to start the machine for cleaning, and it is also prohibited to climb over or walk under the belt. 5.2.2 Material shall be discharged only after the belt conveyor is operating normally; forced startup under overload conditions is strictly prohibited. 5.2.3 Check whether the sound, vibration, and temperature of the motor, reducer, and bearings of each drum are normal. 5.2.4 Check whether the belts are damaged, torn, bulged, or misaligned; also check whether there is any damage or bulging at the joints of each belt. 5.2.5 It is strictly prohibited to adjust the belt while the machine is running. 5.2.6 Check whether all moving parts rotate smoothly. 5.2.7 Check whether the sealant is damaged, whether there is any leakage or blockage in the material feeding chute, and whether the fasteners are loose. 5.2.8 Check whether the tape is slipping and whether the weight mechanism operates smoothly. 5.2.9 Ensure that the materials have been emptied before shutting down the machine. 5.3 Maintenance and Repair 5.3.1 Before dealing with faults such as bulging tubes, reverse wrapping, or folded edges, it is necessary to proceed with the power shutdown procedures and consult with the control room. At least two sets of idler wheels located before and after the faulty area must be removed, and at least two people should work together: one person is responsible for releasing the belt, while another handles the removal of obstructions. 5.3.2 Carry out thorough cleaning after the equipment is shut down, check the condition of the tape joints, as well as whether the foot bolts and other fasteners are loose, and replace any damaged idlers promptly. 5.3.3 When performing repairs or maintenance on the equipment, it is necessary to go through the power-off procedures, apply locks and tags, and set the device to emergency stop and zero position at the site. 5.3.4 When adjusting belt deviation, the operation of the equipment must be confirmed by personnel on site, as well as by the control room operator and supervisors; meanwhile, someone should be assigned to monitor the situation in the power distribution room. 5.3.5 After the maintenance is completed, reinstall the safety protection facilities that were temporarily removed, clean up the site, carry out the procedures for restoring power supply, and keep relevant records. 6 Emergency Measures 6.1 After an incident involving impact by a living organism, rescue efforts should be initiated immediately to assist the injured, with actions taken based on the severity of the injuries. 6.2 In the event of mechanical injury, the source of danger should be cut off first to prevent secondary injuries, and actions should be taken according to the nature of the injury. 6.3 In the event of an electric shock, cut off the power supply to free the person affected as quickly as possible. 6.4 In case of a fire, the source of danger should be cut off first, and fire extinguishing equipment should be used on site to put out the fire ； Activate the company-level emergency response plan if necessary. 6.5 For an operating belt conveyor, if the belt catches fire, the machine should be shut down first and then extinguished; if the idlers catch fire, they should be extinguished first and then the machine should be shut down. 6.6 If olfactory disorders occur due to the prolonged improper use of personal protective equipment, resulting in symptoms such as upper abdominal discomfort, nausea, and fatigue, work should be stopped immediately, and one should go to an area with fresh air to recover. In cases of severe symptoms, medications such as Shidishui, peppermint oil, or cooling ointments can be used.
