ANSI Z136。3被公认为所有医疗环境中激光安全的权威文件。它为在身体结构或功能改变或症状缓解的任何位置安全使用激光进行医疗、诊断、美容、预防和治疗提供了指导。这些应用中使用的激光器被整合到一个设备中，该设备包括输送系统、电源、机械外壳，以及激光器运行所需的相关液体和气体。整个设备称为医疗激光系统（HCLS），本标准适用于与系统安装、操作、校准、维护和服务相关的所有人员。医院、医疗中心、水疗中心、兽医办公室和使用激光的诊所必须使用激光！Z136。3是由医用激光的广泛使用推动的——从医院手术室到办公室和/或诊所环境。 眼科屈光手术（准分子）激光、皮肤科激光和其他医用激光的使用从严格管制的医院环境转向传统医疗、外科和相关行业的广泛应用。现在，大多数医用激光系统都在私人医疗办公室中找到。从这个场所开始，他们已经扩展到可能有有限或兼职医疗监督的区域的化妆品用途，例如在水疗中心和美容院。这些激光系统的环境不仅大大拓宽，而且对使用它们的人的培训也变得更加多样化。医疗激光系统使用模式的快速变化，使得我们必须有一份最新的文件来指导我们如何安全使用这些系统。ANSI Z136。3代表了许多必要的折衷方案，以满足这些医疗激光系统的不同用户群体的需求。 本标准旨在与ANSI Z136结合使用。1.

The ANSI Z136.3 is recognized as the definitive document on laser safety in all health care environments. It provides guidance for the safe use of lasers for medicine, diagnostic, cosmetic, preventative and therapeutic applications in any location where bodily structure or function is altered or symptoms are relieved. Lasers used in these applications are incorporated into an apparatus, which includes a delivery system, a power supply, mechanical housing, and associated liquids and gases as required for operation of the laser.The entire apparatus is referred to as a health care laser system (HCLS), and this standard is intended for use by all personnel associated with the installation, operation, calibration, and maintenance and service of the system. A must for hospitals, medical centers, spas, veterinary offices and clinics using lasers!The Z136.3 was driven by the movement of the widespread use of medical lasers - from hospital operating rooms to the office and/or clinic environment. The use of ophthalmic refractive surgery (excimer) lasers, dermatological lasers and other medical lasers moved from the closely regulated hospital environment into broad applications in conventional medical, surgical and allied professions. The majority of medical laser systems are now found in private medical offices. From this venue they have expanded into cosmetic uses in areas that may have limited or part-time medical supervision, such as in spas and beauty salons. Not only has the environment of these laser systems been greatly broadened, but the training of the people using them has become far more diverse.This rapid change in the pattern of use of health care laser systems has made it essential to have a current document to guide us in the approach to the safe use of these systems. The ANSI Z136.3 represents many necessary compromises to make it fit the needs of this diverse population of users of these medical laser systems.The standard is designed to be used in conjunction with the ANSI Z136.1.
