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

Subject: Hazardous Infrared radiation ?
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 !
