dangerous area, and the packaging machinery shall be equipped with alarm device 3.14 there shall be clear and eye-catching marks for operation, lubrication, safety or warning on the packaging machinery The safety color and safety sign shall comply with the provisions of gb2893 and gb2894, and the graphic symbols in the sign shall comply with the relevant standards or regulations 3.15 the safe operation mechanism of packaging machinery shall be located in a position easy to operate and control by operators 3.16 for the packaging machinery working in the flammable and explosive environment, its machinery and electrical equipment shall have reliable protective measures and conform to relevant standards or regulations 4 Safety protection 4.1 protective device 4.1.2 protective cover shall be provided for exposed moving parts that are dangerous to operators 4.1.3 the protective cover for observing the movement of dangerous parts shall be made of safe transparent materials or other mesh materials 4.1.4 when opening the protective device may cause danger, the device shall be interlocked with the transmission mechanism of packaging machinery 4.1.5 for the isolation protection device with photoelectric control, when the personnel is close to the dangerous work area, the machine shall be shut down in time 4.1.6 during the working period of packaging machinery, it is possible to produce combustion, explosion or radiation due to the packed goods (such as filling combustible body) In case of danger, its protective device shall adopt the structure and materials that can prevent combustion, explosion and radiation, so as to ensure the safety of operators 4.1.7 the safety protection device shall be fixed reliably, not open by itself, and shall have sufficient strength, rigidity, stability and corrosion resistance 4.2 all exposed parts of the driving mechanism packaging machinery that transmit power, such as couplings, gears, sprockets, pulleys and other driving mechanisms, shall be protected in accordance with the provisions of this standard and relevant professional standards 4.3 the feeding mechanism is used to transport packaging containers, and the mechanism of packaging materials, packages or packaged goods shall have sufficient safety protection measures, such as setting up protective fence or adopting photoelectric control, etc., to avoid danger caused by personnel entering the work area or to prevent packaging containers, packaging materials, packages or packaged goods from causing injury to personnel in the process of movement 4.4 filling mechanism 4.4.1 machines or equipment that may cause explosion hazard of packed goods or packaging containers when filling under pressure must be equipped with protective devices to avoid damage to operators caused by flying out of packed products or packaging containers during explosion 4.4.2 when filling toxic and unhealthy substances, it is necessary to ensure that there is no danger to personnel, such as: A install effective dust suction device on the filling work; B install protective cover in front of the filling work; C install spray device on the filling work; D force control the filling process to eliminate secondary filling 4.4.3 when filling inflammable and explosive materials, it must b e ensured to avoid combustion or explosion The measures include: A eliminating or preventing electrostatic influence; B setting ventilation or dust collection device; C avoiding open fire; D the surface temperature of mechanical parts contacting with the filling materials must be lower than the burning point of the filling materials; e filling in the environment with protective gas; f Forced control of filling process to eliminate secondary filling 4.5 sealing, cutting and bundling mechanism 4.5.2 protective measures shall be taken for bonding sealing mechanism to prevent hot melt glue from scalding operators 4.5.3 the rotating parts of the edge rolling sealing mechanism and the rolling sealing mechanism must be equipped with protective covers or ensure that they do not touch the operators when they are working 4.5.4 protective measures shall be taken for the cutting device of packaging materials, such as the protective cover, heat insulation baffle, etc interlocked with the transmission mechanism, to avoid cutting, pinching or scalding to the operator 4.5.5 the binding mechanism shall prevent operators from being bound by the binding belt 5 Operation and maintenance 5.1 packaging machinery shall only be operated and maintained by personnel with technical training 5.2 the packaging machinery shall be provided with operation instructions that can correctly guide the operation of personnel 5.3 the packaging machinery shall be inspected regularly to ensure that the function of the machine or equipment, all parts and safety protection measures are in normal working condition 5.4 the packaging machinery shall be able to adjust, lubricate and maintain daily as far as possible without removing the safety protection device 5.5 for the parts that are difficult to be lubricated manually or need to be lubricated in the dangerous area during the work, the automatic lubrication shall be realized 5.6 during the work of packaging machinery, it is generally not allowed to clean or clean the moving parts If it must be carried out in the working state, preventive measures must be taken to eliminate the accident If appropriate aids are used 5.7 in case of adjustment, maintenance and troubleshooting of the packaging machinery in the moving state, it is only allowed to move the packaging machinery manually or by means of the inching button switch 5.8 if the button switch of the machine or equipment is located outside the operating position of the operator during adjustment and maintenance, or several personnel work at the same time, the operation shall be carried out by a specially assigned person at the working position where the work can be monitored and the machine or equipment can be shut down quickly As long as the work is in progress, the person is not allowed to leave his position 5.9 when the packaging machinery is working, protective measures shall be taken for the eyes and faces of the operators in case of possible injury to them 6 Noise 6.1 packaging machinery shall take noise reduction measures as far as possible The noise Zui loud pressure level limit shall comply with the relevant national labor safety standards 6.2 the noise measurement method of packaging machinery shall conform
