Requirements for laser eye protection (LEP), though different for specific industrial or medical applications, have some common features:1)Protection at one or more wavelengths and 2) High integrated luminance transmittance (ILT)

Due to the method of construction and cost, LEP typically protects against several laser wavelengths. Simultaneously blocking several spectral bands naturally leads to distortion of color perception. Unlike optical density (OD), there is no commo...

Phase Distortion Laser Safety Glasses for Protection against All Laser Wavelengths or All Laser Intensities

Presented at ILSC 2009

Phase distortion laser safety glasses have been experimentally demonstrated and, based on the data, all wavelength protection of the retina is provided using glasses with an optical density (OD) of 3 (0.1% transmission)*. The concept is based on the fact that the laser light absorbed by the polycarbonate glass heats it and changes its index of refraction. A grid of varying transmission on the surface produces a non-uniform intensity in the glass. This non-uniformity results in a non-uniform pha...

Mark McLear, Sperian; - RI USA
Presented at ILSC 2009

ANSI Z 136.7 American National Standard for Testing and Labelling of Laser Protective equipment was developed to provide recommendations for the testing requirements of protective equipment ( eyewear, windows and barriers) used in the laser industry. This paper will concentrate on the testing requirements for absorbing materials used in the manufacturing of laser eyewear. A comparison will be made on how these requirements differ or are aligned with various other laser safety standards including ANSI Z 136.1 For the Safe Use of Lasers and EN 207 Personal eye-protection...

Medical Laser Safety Program at a Large Academic Medical Center: An Overview
Authors:
Christine Krieman, Duke University; Durham NC USA
Presented at ILSC 2009

Ensuring laser safety at a large academic medical center requires, at a minimum, implementing the applicable program elements specified in the ANSI Z136 series of Standards for the Safe Use of Lasers, as recognized by OSHA, FDA, and JCAHO. These laser safety program elements include a consistent hazard evaluation process, an appropriate safety training program accompanied by hands-on competency training, a document management process, and an efficient means for tracking lasers on site. In addition, a Laser Safety Committee can provide cr...

As dermatological lasers employed for skin resurfacing, "rejuvenation," and hair removal move from the dermatology clinic to the spa and even home-use, manufacturers have made great improvements in system safety. With contact sensors and other "smart" sensors that test for skin type, the laser product will only fire when the appropriate contact conditions are present and there is no potential eye hazard. Technically these products must be labeled as Class 4, but there i...

Medical laser systems with more than one laser wavelength were introduced in the market already decades ago. Recently, these advanced devices become a standard in medical care, since with the use of inexpensive diodes multi-wavelength systems can be realized at affordable prices. If the different laser wavelengths can be activated either simultaneously or only at single lines, and in addi...

Burning Behaviors of Drapes and Other Patient Covers

Presented at ILSC 2009

Operation Room fires are still an unsolved problem. The majority of OR-fire happens with other energy sources like electrocautery and endoscopic light sources.
But first the medical community discussed this problem using Lasers. The use of non-woven disposable drapes are named as the most risky situation. This was followed by investigation of several products called Laser safe. But on the other hand woven materials are regarde as Laser safe. Our investigations with different products has shon that the burning behaviour depends by several circumst...

Airway Fires: Concerns, Causes, Case Histories and Prevention
Authors:
Richard S. Hughes, High-Rez Diagnostics, Inc.; Placerville CA USA
Presented at ILSC 2009

The author presented the details of two laser-induced airway fire cases for which he had served as an expert witness, the first at ILSC 2003 and the second at ILSC 2007. The outcome of the first reported case was and continues to be tragic in that the patient, 11 years old at the time of the accident, is permanently eating and breathing through plastic tubes. The outcome of the second case, while not as tragic, resulted in a permanent tracheotomy with its associated problems of periodic tube replacement and airway debridement, speaking...
