title: A simple approach to industrial laser safety.
abstract: Industrial applications of lasers include marking, welding, cutting, and other material processing. Lasers used in these ways have significant power output but are generally designed to limit operator exposure to direct or scattered laser radiation to harmless levels in order to meet the Federal Laser Product Performance Standard (21CFR1040) for Class 1 laser products. Interesting challenges occur when companies integrate high power lasers into manufacturing or process control equipment. A significant part of the integration process is developing engineering and administrative controls to produce an acceptable level of laser safety while balancing production, maintenance, and service requirements. 3M Company uses a large number of high power lasers in numerous manufacturing processes. Whether the laser is purchased as a Class 1 laser product or whether it is purchased as a Class 4 laser and then integrated into a manufacturing application, 3M Company has developed an industrial laser safety program that maintains a high degree of laser safety while facilitating the rapid and economical integration of laser technology into the manufacturing workplace. This laser safety program is based on the requirements and recommendations contained in the American National Standard for Safe Use of Lasers, ANSI Z136.1. The fundamental components of the 3M program include hazard evaluation, engineering, administrative, and procedural controls, protective equipment, signs and labels, training, and re-evaluation upon change. This program is implemented in manufacturing facilities and has resulted in an excellent history of laser safety and an effective and efficient use of laser safety resources.
