Laser radiation can prove to be harmful to the human body. The host machine's laser scanning system is completely sealed by means of a protective housing and
external covers so that its light will not leak outside the host machine as long as the host machine is used normally.
The Center for Devices and Radiological Health (CDRH) of the US Food and Drug Administrator put into forth regulations that relate to laser products on August
2nd, 1976.
These regulations apply to laser products produced on and after August 1st, 1976, and prohibit the sale of laser products without certification.
The following labels certify compliance with the CDRH regulations, and must be attached to all laser products that are sold in the US.
