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...$28.00

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...$28.00

Recent Laser Accidents at Department of Energy Laboratories
Authors:
Connon Odom, Los Alamos National Laboratory; Los Alamos NM USA
Presented at ILSC 2007
Recent laser accidents at research laboratories across the Department of Energy complex are reviewed in this paper. Factors that contributed to the accidents are examined. Conclusions drawn from the accident reports are summarized and compared. Control measures that could have been implemented to prevent the accidents will be summarized and compared. Recommendations for improving laser safety programs are made.$28.00

CDRH Activities Affecting the Marketing of Laser Products in the United States
Authors:
Jerome Dennis, CDRH/FDA; Gaithersburg MD USA
Presented at ILSC 2007
This tutorial paper provides a brief summary of the CDRH activities and philosophies that impact the marketing of laser products in the United States. The paper contains background and history followed by a listing of the more recently published guidance documents with brief descriptions of the policies that they contain. Although the guidance documents can freely be accessed from the Internet, this paper can serve as a useful navigational aid in locating the documents that are needed by the manufacturers.$28.00

Optical Radiation Safety Requirements for LEDs According to Their New Status in Between Laser and Lamp Safety Standards
Authors:

Werner Horak, Siemens AG; Munich Germany
Presented at ILSC 2007
The international laser safety standard IEC 60825-1 is currently under revision. Since 1993, the scope of this standard was also extended LEDs. In terms of these optoelectronic devices, the new revision will provide the following innovations:
LEDs will be deleted from the scope of the laser safety standard and the optical radiation hazard should be assessed with the recently adopted safety standard IEC 62471 for lamps and lamp systems. However, thi...$28.00

Authors:
Robert Weiner, Weiner Associates; Manhattan Beach CA USA
Presented at ILSC 2007
The IEC TC-76 committee on laser safety has recently published Edition 2 to the IEC 60825-1 laser safety standard. This paper will briefly describe the extensive amendments that are included in the new Edition: removal of LEDs from this standard; revision of the definition of human access for better consistency with real hazards; revision of measurement criteria to increase the distance used for classification of diverging beams; simplification of measurement criteria for small sources; and application of more stringent measurement criteri...$28.00

Presented at ILSC 2007
Laser safety testing is performed under the umbrella of the IECEE (IEC System for Conformity testing and Certification of Electrical Equipment), a branch of IEC, also known as the CB Scheme. Its members include 137 National Certification Bodies (NCBs) from 39 countries. The significant growth of the organization is reflected in the release of over 40 thousand CB certificates and test reports in the year 2005. The Committee of Testing Laboratories (CTL) is the technical branch of the IECEE. Th...$28.00

Summary of Changes to the Next Edition of ANSI Z136.1
Authors:
Nikolay Stoev, Valkom Laser Consulting; Toronto ON Canada
Presented at ILSC 2007
This presentation is a summary of the changes introduced into the next edition of the ANSI Z136-200X standard compared to the current 2000 edition. It resulted from the author's effort in reviewing the drafts within the SSC-1 subcommittee and the editorial group. Revised ANSI standards currently lack sections summarizing the introduced changes, which is somewhat difficult for users of the new editions. One would have to read the whole document to identify some changes. The summary covers all normative sections including appendices and some non-normative...$28.00

Presented at ILSC 2007
One of the special properties of lasers is the emission of monochromatic radiation. Filters and mirrors have to provide high coefficients of absorption and/or reflection. Especially for eye safety filters the transient laser radiation must not exceed the MPE. Various medical laser systems on the market today include different lasers and allow a combined application with more than one wavelength.These new developments lead to new...$28.00
