Due to the wide range of wavelength, energy and pulse characteristics of laser beams, When using laser products, the degree of potential hazards varies greatly, and it is not possible to simply classify laser products using a unified safety limit. The classification system for the degree of optical radiation hazards of devices and laser products is evaluated and control measures are determined. --- Part 2.Safety of optical fiber communication systems (OFCS). Based on the safety of reasonably foreseeable fault conditions [such as cable break, optical The level is divided according to the degree of exposure to optical radiation in the case of loose fiber connectors, etc. The corresponding hazard level of accessible locations is specified based on the characteristics of the accessible locations to determine the equivalent safety protection measures. --- Part 3.Guide to laser shows and performances. For use in theater projections and stage performances and other similar places 3B and 4 laser Any possible occurrence during laser operation that exceeds the maximum permissible exposure that may cause biological effects and hazards to human eyes and skin The MPE is designed to clarify the responsibilities of on-site design, installation, operation and performance personnel, as well as the risk control and evaluation Estimate to reduce risk. --- Part 4.Laser protection screens. Aims to specify permanent and temporary (such as maintenance) laser protection screens used to enclose the working area of laser processing machines. Protective screens and technical requirements for special laser protective screens to prevent people around the processing area from being harmed by laser radiation. --- Part 5.Producer's checklist for GB/T 7247.1.Aims to provide a reference inspection procedure to ensure Verify whether the product meets the classification and requirements of GB/T 7247.1 for equipment, and enhance the enforceability and usability of GB/T 7247.1 in use. Operability. --- Part 8.Guidelines for the safe use of lasers on the human body. Aims to guide how to incorporate the safe use of lasers into medical laser practice. Practice, establish safety procedures, preventive measures and user control measures, strengthen the establishment of a system for all personnel involved in the use of lasers The necessity of safety framework system and training. --- Part 9.Maximum permissible exposure to incoherent optical radiation. This is intended to provide the maximum permissible exposure to the human eye from artificial light sources of 180nm to 3000nm. MPE limits for controlling light radiation exposure when applied to the skin. --- Part 12.Safety of free space optical communication systems (FSOCSs) for information transmission. Aims to give 180nm~ Guidelines for the manufacture of laser products and systems for point-to-point or point-to-multipoint free-space optical data transmission in the 1 mm wavelength range South, and safe use requirements to protect people from the potentially dangerous optical radiation generated by FSOCSs. --- Part 13.Classification measurement of laser products. Aims to give the emission level of laser output energy according to GB/T 7247.1 Measurement and analysis methods give guidance on the classification of laser products. --- Part 14.User Guide. It puts forward requirements for users to use laser products exceeding Class 1 and Class 2, aiming to help users Product users and their manufacturers understand the general principles of safety management, identify possible hazards, assess the severity of potential hazards, establish and Provide appropriate control measures. --- Part 17.Safety of passive optical components and cables used in high optical power optical fiber communication systems. For high optical powers above Class 3B in operation, safety precautions for thermal effects, optomechanical effects and related effects are given. To prevent and protect other safety issues that may be caused to connectors, etc. The serial numbers and italic characters in parentheses (or square brackets) in this document refer to the relevant clauses and content, so that this document can be used in conjunction with GB/T 7247.1-2024.
