RE: Hazardous Infrared radiation ?
IEC60825-1 contains requirements for noncoherent infrared radiation. Likewise does EN60825-1, with Amendment A11. Regards, Peter L. Tarver, PE ptar...@nortelnetworks.com From: Israel Yeshurun [mailto:israel_yeshu...@creoscitex.com] Can some comment on this ? Can Infrared radiation (not Laser) be hazardous ? Obviously, high enough IR intensity should be hazardous. As the eye may not blink under exposure to IR (as the eye can not see it) the natural eye protection mechanism may not function. Any standards, guidelines available for permissible exposure limits to Infra red radiation ? Many thanks to every contribution ! with Best Regards, Israel Yeshurun. CreoScitex. Israel

RE: Hazardous Infrared radiation ?
Israel, Get yoursel;f a copy of EN 60825 (IEC 825) . . . that is a Laser Safety specifications and provides guidance on permissible limits for various wavelengths . . . Additionally, if you intend to ship to the US, reference 21 CFR 1040 (United States 'Code of Federal Regulations'). The CDRH (Center for Devices & Radiological Health - an office of the FDA) is responsbile for compliance of laser products in the US. Here's the link for the CDRH and 21 CFR 1040 http://www.fda.gov/cdrh/radhlth/cfr/21cfr1040.10.pdf http://www.fda.gov/cdrh/ John Juhasz Fiber Options, Bohemia, NY -Original Message- From: Israel Yeshurun [mailto:israel_yeshu...@creoscitex.com] Sent: Monday, May 22, 2000 11:33 AM To: 'emc-p...@majordomo.ieee.org' Subject: Hazardous Infrared radiation ?

RE: Hazardous Infrared radiation ?
The American Conference of Governmental Industrial Hygienists (ACGIH) lists
recommended limits in their publication "Threshold Limit Values for Chemical
Substances and Physical Agents". The limits are for wave lengths of 770nm to
3um and are intended to protect the eye. Their web page is www.acgih.org

Can some comment on this ?
Can Infrared radiation (not Laser) be hazardous ? Obviously,
high
enough IR intensity should be hazardous. As the eye may not blink
under
exposure to IR (as the eye can not see it) the natural eye
protection
mechanism may not function.
Any standards, guidelines available for permissible exposure
limits to
Infra red radiation ?
Many thanks to every contribution !
