In 1968, the American National Standards Institute

8、 (ANSI) approved the initiation of the Safe Use of Lasers Standards Project under the sponsorship of the Telephone Group. Prior to 1985, Z136 standards were developed by ANSI Committee Z136 and submitted for approval and issuance as ANSI Z136 standards. Since 1985, Z136 standards are developed by th

9、e ANSI Accredited Standards Committee (ASC) Z136 for Safe Use of Lasers. A copy of the procedures for development of these standards can be obtained from the secretariat, Laser Institute of America, 13501 Ingenuity Drive, Suite 128, Orlando, FL 32826 or viewed at www.z136.org. The present scope of A

10、SC Z136 is to protect against hazards associated with the use of lasers and optically radiating diodes. ASC Z136 is responsible for the development and maintenance of this standard. In addition to the consensus body, ASC Z136 is composed of standards subcommittees (SSC) and technical subcommittees (

11、TSC) involved in Z136 standards development and an editorial working group (EWG). At the time of this printing, the following standards and technical subcommittees were active: SSC-1 Safe Use of Lasers (parent document) SSC-2 Safe Use of Lasers and LEDs in Telecommunications Applications SSC-3 Safe

12、Use of Lasers in Health Care SSC-4 Measurements and Instrumentation SSC-5 Safe Use of Lasers in Educational Institutions SSC-6 Safe Use of Lasers Outdoors SSC-7 Eyewear and Protective Barriers SSC-8 Safe Use of Lasers in Research, Development, and Testing SSC-9 Safe Use of Lasers in Manufacturing En

18、is purpose of this American National Standard is to provide specific guidance for the safe use of lasers in manufacturing environments. It has been published as part of the ANSI Z136 series of laser safety standards. The base document of the series is the American National Standard for Safe Use of L

19、asers, ANSI Z136.1. The procedures and methodologies described in this standard are based on requirements previously established in ANSI Z136.1 and are intended to give more specific practices for accomplishing laser safety, and to provide more specific user guidance for protecting individuals with

20、the potential for laser exposure when lasers are used in manufacturing environments. This standard includes policies and procedures to ensure laser safety in areas where lasers are used in manufacturing, including public and private industries, and product development and testing settings. In genera

21、l, this standard may be used independently of ANSI Z136.1; however, instances iii where additional guidance contained in ANSI Z136.1 is required are noted in the text of this document. The body of this standard is a normative standard that applies to manufacturing environments that use lasers. The a

22、ppendices, excluding Appendix A, are informative providing examples and discipline specific supplementary information. It is expected that this standard will be periodically revised as new information and experience in the use of lasers are gained. Future revisions may have modified content and use

23、of the most current document is highly recommended. While there is considerable compatibility among existing laser safety standards, some requirements differ among state, federal, and international standards and regulations. These differences may have an effect on the particulars of the applicable c

24、ontrol measures. Occasionally questions may arise regarding the meaning or intent of portions of this standard as it relates to specific applications. When the need for an interpretation is brought to the attention of the secretariat, the secretariat will initiate action to prepare an appropriate re

25、sponse. Since ANSI Z136 standards represent a consensus of concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason, the secretariat is not able to provide an instant response to interpretation requests except

26、 in those cases where the matter has previously received formal consideration. Requests for interpretations and suggestions for improvements of the standard are welcome. They should be sent to ASC Z136 Secretariat, Laser Institute of America, 13501 Ingenuity Drive, Suite 128, Orlando, FL 32826. This

27、 standard was processed and approved for submittal to ANSI by ASC Z136. Committee approval of the standard does not necessarily imply that all members voted for its approval. Robert Thomas, Committee Chair Sheldon Zimmerman, Committee Vice-Chair Ben Edwards, Committee Secretary iv Notice (This notic

28、e is not a normative part of ANSI Z136.9-2013, American National Standard for Safe Use of Lasers in Manufacturing Environments.) Z136 standards and recommended practices are developed through a consensus standards development process approved by the American National Standards Institute. The process

29、 brings together volunteers representing varied viewpoints and interests to achieve consensus on laser safety related issues. As secretariat to ASC Z136, the Laser Institute of America (LIA) administers the process and provides financial and clerical support to the committee. The LIA and its directo

The laser hazard classification system is based entirely on the laser radiation emission. Non-beam hazards must be dealt with separately and are addressed in Sec

36、tion 7. NOTESee Section 10 for titles of ANSI and other standards and codes cited in this standard. AMERICAN NATIONAL STANDARD Z136.9-2013 4 1.3 Laser Safety Programs. 1.3.1 General. Management (employer) has the fundamental responsibility to ensure the safe use of lasers owned and/or operated in fa

37、cilities under its control. Management shall establish and maintain an adequate program for the control of laser hazards. Employer and/or facility safety programs and employee training programs shall be provided for Class 3B or Class 4 lasers and laser systems. Employer and/or facility safety progra

38、ms and employee training should be provided for laser systems containing embedded Class 3B and Class 4 lasers, if accessed by employers staff. Service of such systems (embedded Class 3B and Class 4 lasers) by outside vendors does not require employer staff laser safety training. The LSO shall approv

39、e safety procedures implemented at times when such systems are accessed and no longer in a Class 1 configuration. Employer and/or facility safety programs and employee training programs are not required for Class 1 lasers and laser systems that do not contain embedded Class 3B and Class 4 lasers (se

40、e Section 5 and Table 1.1). The following guidelines for laser safety programs contain requirements (designated by shall) and recommendations (designated by should). In the case of a recommendation it may be useful for the employer to review Section 3 of this standard and perform a hazard evaluation

41、, with particular emphasis on the total foreseen risk based on consideration of the laser, laser system and application, as well as the environment in which it is used and the personnel using the laser. The evaluation should include considerations such as the likelihood of the use of viewing optics,

42、 and the intentional or unintentional misuse of a laser that, under normal conditions, would not be considered hazardous. In many situations the implementation of a recommendation may not be necessary; in other situations, it may be useful or prudent to implement the recommendation in order to ensur

43、e the safe use of lasers for a specific application. 1.3.2 Laser Safety Program Provisions. When identified as necessary, the laser safety program established by the employer (see Table 1.1) shall include provisions for the following: a) Designation of an individual as the LSO with the authority and

44、 responsibility to effect the knowledgeable evaluation and control of laser hazards, and the implementation of appropriate control measures, as well as to monitor and enforce compliance with required standards and regulations. The specific duties and responsibilities of the LSO are designated in nor

45、mative Appendix A.1Throughout the body of this standard, it shall be understood that wherever duties or responsibilities of the LSO are specified, it will mean that the LSO either performs the stated task or ensures that the task is performed by a qualified individual(s). b) Education of authorized

46、personnel (e.g., LSOs, operators, in-house and/or vendor service personnel) in the safe use of lasers and laser systems and, as applicable, the assessment and control of laser hazards. This may be accomplished through training programs. Employers should consider the benefits of initiating awareness

47、training for employees working with and around lasers and laser systems greater than Class 1. If 1A normative appendix contains information that is required to implement the standard and is therefore, officially part of the standard. AMERICAN NATIONAL STANDARD Z136.9-2013 5 training is warranted for

48、 embedded lasers, it shall extend to those routinely around the systems who will be present when maintenance requiring beam access or service occurs (see Section 5 and Appendix E). When service is conducted by an outside firm/vendor, supporting documentation of appropriate laser safety training shou

49、ld be presented to the employer and meet to the approval of the employers Health & Safety Committee and/or the employers LSO. c) Application of adequate control measures for the mitigation of laser hazards as required in Section 4. d) Incident investigation, including reporting of alleged accidents to the LSO, and preparation of action plans for the prevention of future accidents following a known or suspected incident. e) An appropriate medical examination is considered in accordance with Section 6. f) Formation of a Laser Safety Committee when the number, hazards, complexity an
