    A three-dimensional thermal model is used to investigate the damage threshold for hazard assessments of lasers projecting non-uniform or non-symmetric images on the retina. The two source types considered are an array of sources and an elliptical source. In the array of sources, the spacing and size ratios of the sources are va...

    Recently, a number of new threshold values for retinal thermal damage became available that allow a more complete analysis of the dependence of the threshold on the retinal spot size diameter for different pulse durations. The data originate from non-human primate (NHP) models, excised retinas as well as computer models and compare well with each other. A distinctive dependence...

    A practical approach to laser safety planning for the research laboratory must consider flexibility as a key component. Refinement in experimental design, a process of the scientific method, is inevitable. Each time the optical layout is modified, new hazards must be identified and neutralized ...

    Presented at ILSC 2007

    Project ORION currently underway at AWE is Building the largest laser system in the UK. This is a MOPA configuration Nd doped glass laser system for high energy density physics research. The laser comprises 10 beams of 30cm aperture delivering 5kJ in 1ns at 351nm to target and 2 beams of 60cm aperture utilising CPA to deliver IPW each at 100nm in 0.5ps pulses. The facility comprises several designated compartments in a building around 100m long and 60m width. The major hazards are g...

    Presented at ILSC 2007

    Two experienced Laser Safety Officers offer their own insight into some unique selected industrial laser safety issues seen or experienced. The issues to be presented are safety associated with optical tables, single laser warning lights, walkway laser safety, approaches and techniques for laser enclosures, impact of older workers using lasers, laser warning signs messages, and laser skin exposure. Each issue is presented using a two t...

    Presented at ILSC 2007

    During the last decade one of the groups with the highest number of laser injuries has been student workers. Improved laser safety training can be a significant factor in reducing laser accidents among university students. Until recently suitable laser safety training materials have not been widely available to meet the specific needs of university students working with lasers in research laboratories. T...

    The Importance of Hands-on Learning
    Authors:
    Leah Cridlin, Rockwell Laser Industries, Inc.; Cincinnati OH USA
    Presented at ILSC 2007

    As trainers we must focus on the learners outcome. Hands-on learning allows students to incorporate what is being taught into real world situations, thus allowing them to retain more information. Adult learners need to understand why they are learning a new task/skill. People learn better through active experience than passive listening. People learn better through interacting with one another than working alone. Trends and Causes for Hands on Learning Include: Teaming of employees Many organizations have reduced their managerial hierarchies, empowered their empl...

    Laser Non-Beam Hazards - An Overview
    Authors:
    Ben Edwards, Duke University; Chapel Hill NC USA

    Presented at ILSC 2007

    Non-beam hazards (NBH) are those hazards that result from factors other than direct human exposure to a laser beam. NBH can pose a significant safety and regulatory concern. While the focus of the laser safety community has been justifiably dominated by the identification and control of laser beam hazards, safety professional also have an obligation to similarly address NBH. High power laser beams can blind, damage skin, and ignite combustible material, but it is NBH (e.g. electrocution) that have accounted for the fat...

    Presented at ILSC 2007

    Laser material processing is gaining increasing importance in micro and macro machining. During laser processing of polymers, metals, and ceramics dangerous air pollutants have to be considered with regard to occupational safety. Moreover, technical measures for the handling of Laser Generated Air Contaminants (LGACs) often contribute to more than 10 % of the operating costs of laser machinery. Therefore, data ar...
