Plan to attend The IMTS 2018 Conferences to expand your industry knowledge as you learn from the pros.
This presentation will cover how active laser guarding developments have become ever more necessary in the role of laser safety and the prevention of injury due to high power laser radiation.
The safety of personnel in close proximity to high powered lasers is paramount. This paper looks into how engineered safety solutions are implemented and how to determine the most cost-effective option – passive or active laser guarding. The avoidance of burn injuries, potential blindness, or even death is addressed in regard to laser safety. The latest developments in active laser guarding are examined which conform to the international and U.S. laser safety standards.
As more laser processes are using ever more powerful lasers in manufacturing, the requirement threshold is more often crossed from passive to active laser safety systems and this trend looks to be set to continue. Consequently, more has to be done to safeguard personnel and all those working with lasers should be aware of the potential dangers which are not always obvious – especially when dealing with wavelengths outside the visible spectrum.
Paul Tozer, the presenter, will cover when and why to use active laser guarding and examines the limits of passive guarding depending on the laser power density. (An active laser guarding system will switch off the laser virtually immediately whenever a stray laser beam is detected striking a laser safety enclosure). The paper describes how to calculate laser safe limits so that laser safety officers know the appropriate system to use and describes current systems on the market and how they work.
The legal implications and consequences of not adhering to the relevant laser safety standards can lead to serious situations especially if people are blinded, otherwise burned, or injured by high powered lasers.
Engineered, professionally designed, proven, and certified laser safety control systems must be used to ensure all practical steps have been taken to prevent the escape of laser radiation that can cause harm to personnel, equipment, and infrastructure outside of the designated laser safety area.
Awareness of the laser safety protective measures that must be implemented is before the installation and commissioning of the laser. Prompt training of laser hazards is vital and all establishments using a laser must have a laser safety officer who must be laser safety trained.
