A variety of exposure limit tests with different materials and lasers led to non reproducible results, which can lead to false interpretation concerning the exposure limit and overestimated lifetime predictions of laser guards. Thus equal and comparable conditions for repeated test must be ensured to maintain the integrit...

Control of Non-Beam Hazards Under IEC TR 60825-14

Roy Henderson, Bioptica; Cambridge Great Britain
Presented at ILSC 2011

A series of international documents relating to the safety of lasers is issued by IEC (the International Electrotechnical Commission). These include safety standards that define requirements for laser products (such as IEC 60825-1) and guidance documents (called Technical Reports) that provide recommendations for the safe use of laser equipment. The key document in the latter category is IEC TR 60825-14 (Safety of Laser Products, Part 14: A Users Guide).

There is sometimes confusion, particular amongst those who have no need to use these international document...

Laser Dyes and Solvents
Authors:
Sharli Frederiksen, Mayo Clinic; Scottsdale AZ USA
Presented at ILSC 2011

Organic dye solutions can serve as the lasing medium in some laser systems. They might offer a wider bandwidth which provides the flexibility seen in the tunable and pulsed laser systems. A few examples of laser dyes include coumarin, fluorescein, malalchite green, rhodamine, and stilbene. Most laser dyes, or the solvents in which they are dissolved, are toxic; some are carcinogenic or mutagenic. A few examples of some common laser dye solvents include water, glycol, alcohols, benzenes, hexane, cyclohexane, dimethylformamide, and toluene. As the laser is used, the dye solutions degrad...

ILSC 2011 Paper #404 (An International Standard for Laser Eye Protection)

An International Standard for Laser Eye Protection
Authors:
Roy Henderson, Bioptica; Cambridge Great Britain
Presented at ILSC 2011

Global standards covering the safety requirements for laser products and equipment have been in existence for many years (principally the IEC 60825 series of standards), Laser eye protection, however, is subject to differing technical requirements in different parts of the world. The US has recently introduced ANSI Z136.7 covering the testing and labeling of laser protective equipment while in Europe the two laser eyewear standards EN 207 and EN 208 have been in force for a considerable time. European requirements for testing and marking laser protection differ in ...

Presented at ILSC 2011

A common misconception often heard is that if its a (fill in the color) laser; wear the same color Laser Eye Protection (LEP) definitely not the right approach. This presentation will discuss a simple approach to selecting protective eyewear. The first step is to ask a few basic questions such as, what wavelength or wavelengths, is the laser pulsed, continuous wave, whats the expected power output, am I indoors lights on or out? After answering these que...

Novel Software Platform for Advanced Optical Radiation Safety Analysis
Authors:

Presented at ILSC 2011

This paper describes the development of a software based platform for the optical radiation safety analysis of today's generation of versatile light sources whether they be laser, LED or lamp, and whether they be continuous wave, single line, multi-line, narrowband or broadband in emission spectrum. The analysis is calculated against the international optical radiation safety standards IEC 60825 (lasers) and IEC 62471 (lamps) but can be expanded t...

With more complicated operations the risk of any accident or mismanagement increases. But the question is if with more regulation the safety for staff and patient really increases or an interference of different regulations happens. But no standard can prevent mismanagement. With the international trend of overwhelming regulations in all parts of life even in the hospitals there are created new regulations by sociologist and psychologist and they in...
