Laser Injury Expert Witness

Richard S. Hughes, Ph.D., provides expert witness services for the defense or plaintiff in cases involving laser injury, whether such injuries take place in health care facilities, industrial facilities, government establishments or academic settings.

Please note the following key laser injury expert witness qualifications:

  1. Dr. Hughes is a former professor of physics and having taught biophysics, which deals (among other topics) with the details of light/tissue interactions, is exceptionally well-qualified to address the photo-biological aspects of laser injury.
  2. Having performed laser research for more than twenty years and having been awarded twenty three laser and laser-related patents, he has exceptional knowledge in the areas of laser principles, laser beam characteristics and laser beam/matter interactions (from tissue to endotracheal tubes).
  3. Dr. Hughes serves on the ANSI Accredited Standards Committee Z136 and a number of subcommittees that have the responsibility for developing standards for the safe use of lasers, including ANSI Z136.3 (the American National Standard for the Safe Use of Lasers in Health Care Facilities). (Please note the relevant committee and subcommittees listed below and in his CV on Credentials page.) Thus, he is exceedingly well aware of the standard of care with respect to the use of lasers in health care facilities and in other laser-use environments.
  4. As Dr. Hughes has trained laser users and laser safety officers (LSOs) and has consulted in the area of laser safety for more than twenty five years, he is well aware of the requirements for both the safe applications of lasers and the administration of laser safety programs governing these applications.

The following is a list of the committee and subcommittees relevant to the safe use of lasers that Dr. Hughes serves on:

  • Member of the ANSI Accredited Standards Committee Z136 on the Safe Use of Lasers.
  • Member of the ANZI 136 Editorial Working Group on the Safe Use of Lasers.
  • Member of the following ANSI Z136 Standards Subcommittees (SSC): SSC-4, Safe Use of Lasers in Health Care Facilities; and SSC-6, Safe Use of Lasers Outdoors.
  • Member of the following ANSI Z136 Technical Subcommittees (TSC): TSC-4, Control Measures and Training; and TSC-5, Non-Beam Hazards (includes health care facility hazards, e.g., endotracheal tube fires, etc.).

The following is a list of the publications and software relevant to laser safety authored, co-authored, edited or developed by Dr. Hughes:

  • "LIA* Guide to Medical Laser Safety," 1997 (contributing author).
  • "LIA Guide to Non-Beam Hazards Associated with Laser Use," 1999 (contributing editor).
  • "American National Standard for Safe Use of Lasers," ANSI Z136.1-2000 (member of the now-designated Editorial Working Group).
  • "Fire in the Hole: An Endotracheal Tube Fire," Proceedings of the International Laser Safety Conference (ILSC) 2003.
  • "Another Airway Fire: When Will Such Accidents Cease?" Proceedings of the International Laser Safety Conference (ILSC), 2007.
  • "Airway Fires: Concerns, Causes, Case Histories and Prevention," Proceedings of the International Laser Safety Conference (ILSC), 2009.
  • "Eye Safety Considerations of a Laser-Based Rail Flaw Detection System," Proceedings of the International Laser Safety Conference (ILSC), 2009.
  • "American National Standard for Safe Use of Lasers in Health Care Facilities" ANSI Z136.3-2005 (member of the Editorial Working Group).
  • Co-developer of LaserPro and MedLase Tracker, laser safety software for laser safety officers in the non-medical and medical environments, respectively.
