CH2.4 Exempt Devices CH2.4.1 A variety of commercially-available consumer, business, and industrial applic
24、ation laser and optical radiation devices are exempted from the authorization requirements of the Nonionizing Radiation Safety Program because of their common usage and negligible potential for hazardous exposure under conditions of normal use. Individuals shall consult with the RSO if there is a qu
25、estion regarding applicability of program exemption to their particular situation or device. CH2.4.2 The following devices are exempt from control: CH2.4.2.1 Lasers and laser systems which are designated Class 1, 1M, 2, 2M, and 3R such as laser printers, laser copiers, CD/DVD players, bar code scann
26、ers, laser pointers, etc. CH2.4.2.2 Equipment utilizing non-laser optical devices such as photographic strobe units and high intensity discharge lamps utilized for facility lighting.
