SAFETY OF LASER BEAM
1. Safety of laser beam
This machine has been certified by the manufacturer to Class 1 level under the radiation performance
standards established by the U.S.DHHS (Department of Health and Human Services) in 1968. This
indicates that the product is safe to use during normal operation and maintenance. The laser optical
system, enclosed in a protective housing and sealed within the external covers, never permits the laser
beam to escape.
2. The CDRH Act
A laser-product-related act was implemented on Aug. 2, 1976, by the Center for Devices and Radiological
Health (CDRH) of the U.S. Food and Drug Administration (FDA). This act prohibits the sale of laser products in
the U.S. without certification, and applies to laser products manufactured after Aug. 1, 1976. The label shown
below indicates compliance with the CDRH regulations and must be attached to laser products marketed in the
United States. On this machine, the label is on the right.
