本标准提供了安全使用波长在180 nm和1 mm之间的激光器和激光系统的建议。制造环境中的激光应用包括但不限于材料加工、制造、激光对准、调平、库存、计量和机器视觉。本标准的目的是为激光和激光系统的安全使用提供合理和充分的指导。实现这一点的一种实用方法是:（1）根据激光和激光系统的相对危险性对其进行分类，然后（2）为每种分类指定适当的控制措施。

This standard provides recommendations for the safe use of lasers and laser systems that operate at wavelengths between 180 nm and 1 mm.Laser applications in the manufacturing environment include, but are not limited to, materials processing, fabrication, laser alignment, leveling, inventory, metrology, and machine vision.The objective of this standard is to provide reasonable and adequate guidance for the safe use of lasers and laser sysems. A practical means for accomplishing this is first to(1) classify lasers and laser systems according to their relative hazards and then to(2) specify appropriate controls for each classification.
