CHAPTER I - Overview of Safety Requirements for Lasers

1.1 Registration

Class IIIb and IV Lasers and laser systems must be registered with the Office of Radiation Safety. The registrant must be a full time faculty or staff member at ASU who bears overall responsibility for safe use of registered equipment. New equipment must be registered prior to operation. The ASU commodity code for purchasing regulated lasers is 781092. Class IIIb and IV Lasers and laser systemsbrought to ASU must be registered with ORS also.

1.2 Laser Classification

Lasers at ASU must be classified in accordance with provisions of Chapter 3 of this document. Lasers purchased commercially may retain the classification provided by manufacturers in compliance with requirements of the Federal Laser Product Performance Standard provided modifications altering the classification have not been made. Modified lasers, or lasers constructed on site, must be classified by the Laser Safety Officer.

1.3 Training

All individuals operating Class IIIb and Class IV lasers or laser systems must obtain training on the hazards associated with the equipment and proper safety control measures.

1.4 Safety Control Measures

Class IIIb and Class IV lasers or laser systems must be operated under administrative and/or engineering control measures approved by the Laser Safety Officer prior to operation. These measures might include written procedures for operation and/or laser servicing.

1.5 Laser Surveys

Periodic safety surveys of lasers and laser control measures will be made by the ORS.

1.6 Exemption of Class I, Class II and Class IIIa Lasers

Class I, II, and IIIa lasers or laser systems are exempt from all requirements of this manual. Class IIIb or IV lasers are usually embedded in devices of a lower class, however. Modification or service of Class I or II or IIIa lasers or laser devices which results in access to laser radiation of a higher class laser shall require compliance with requirements for the embedded lasers.
