    Laser Processing Safety - Essence of Safety Requirements for Laser Processing, Worldwide and Recent Technology Challenges to Control Measures

    Presented at ILSC 2007

    Historically, CO2 and Nd:YAG lasers and workstations have predominated in our concepts of "high powered lasers". During the last few decades, safety control measures and guidelines have been developed, and the properties of the more prominent laser technologies were, naturally, used as the foundation. From laser bio-effects statements to complete vertical standards for laser processing machines, certain assumptions were made about modal properties and focus ability, and t...

    Unattended Laser Operation in R&D
    Authors:
    Ken Barat, Lawrence Berkeley National Lab; Berkeley CA USA
    Presented at ILSC 2007

    The ANSI Z136.1.2000 standard section 4.1.1.3 Unattended Laser Operation is a section that is made up of 5 paragraphs, which address unattended laser operations of different laser hazard classifications. Of particular interest to this laser safety officer is unattended laser operation of class 3B and class 4 laser systems. The existing standard calls for the use of the standard ANSI Z535.1 Danger sign with appropriate instructions regarding the hazards of entry into the space when no operator is present. The goal of this presentation is to present this is a common scenari...

    The Manufacturer's Role in Laser Safety

    Presented at ILSC 2007

    The laser manufacturer, as the laser industry leader, has a dual role in promoting and assuring laser safety. The first role, and regulatory mandate, is to manufacturer a safe laser product -- one that is compliant with national and international product safety regulations; however, to promote laser safety the manufacturer may need to do more than produce a safe product. Presenting a positive laser safety message to their customers is their second role and equally as important as manufacturing a safe lase...

    Laser Protocols
    Authors:
    Ken Barat, Lawrence Berkeley National Lab; Berkeley CA USA
    Presented at ILSC 2007

    The ANSI Z136.1 has several sections were the authority of the laser safety officer to alter or adapt the standard's control measures to their particular laser applications is outlined. Recognizing that ANSI Z136.1 is a horizontal standard and is a user guidance document; and as part of an on going philosophy of information to laser users the laser safety program at Lawrence Berkeley National Laboratory has developed a number of laser protocols, or codes of conduct. Each protocol outlines an evaluation of a section of the present ANSI Z136.2000 that are not completely compatible with a res...

    Presented at ILSC 2007

    Over the years many efforts and discussions have been spent on the development of the technical report IEC 60825-8, Guidelines for the safe use of medical laser equipment , the second edition being part of present committee work. This report is a collection of safety rules based on experiences with laser applications, in order to help to prevent unsafe conditions, which could ...

    Presented at ILSC 2007

    Nanoparticles are generated as by-products during laser ablation. The size distribution of particlulate emission depends strongly on the applied laser pulse duration. The number frequency of nanoparticles may increase up to 99% with shorter pulse length. In order to provide safety-related statements on nanoparticles generated during laser materials processing, the particle size distribution during ...

    Laser Hazards from Pulsed Lasers
    Authors:
    Wesley Marshall, US Army CHPPM; APG MD USA
    Presented at ILSC 2007

    Determining the correct maximum permissible exposure (MPE) when a laser is pulsed becomes complex when the laser output beam consists not of regularly spaced pulses of short duration (tens of nanoseconds) and a moderate pulse repetition frequency (PRF), but instead consists of pulse groups that contain several short pulses of a few nanoseconds, or even shorter duration, inside of a macro-pulse that could last for tens of microseconds or even milliseconds. The structures of pulse trains are becoming ever more complicated in that groups of macro-pulses are sometimes repeated at a periodic ...

    Contrasting the Broad-Band Exposure Limits with Laser MPEs
    Authors:
    David Sliney, US Army CHPPM; Aberdeen Proving Ground MD USA
    Presented at ILSC 2007

    Whenever a laser specialist or an engineer employs a spreadsheet and compare and plot laser MPEs with broad-band limits, they see apparent differences and disconnects that can be quite puzzling. This is a particular concern of those trying to assess the optical risks of viewing bright LEDs. The rationale behind the two sets of exposure limits necessarily differ. For a laser, only the hazards at a wavelength of interest are reflected in the MPE, and competing hazard mechanisms lead to, at most, two limits, or "dual limits." However, with broad...
