| CAUTION
Laser hazard Use of controls, adjustments, and procedures other than those specified herein may result in hazardous laser radiation exposure. Laser safety precautions for enclosed systems Under normal operating conditions, optical fiber telecommunication systems are completely enclosed; nonetheless, the following precautions shall be observed: 1. Because of the potential for eye damage, technicians should not stare into optical connectors or broken fibers 2. Under no circumstance shall laser/fiber optic operations be performed by a technician before satisfactorily completing an approved training course 3. Since viewing laser emissions directly in excess of class I/1 limits with an optical instrument such as an eye loupe greatly increases the risk of eye damage, appropriate labels must appear in plain view, in close proximity to the optical port on the protective housing/access panel of the terminal equipment. Safety Laser safety .................................................................................................................................................................................................................................... 1-10 Alcatel-Lucent - Proprietary See notice on first page 365-312-875R5.2 Issue 1, March 2007 Laser safety precautions for unenclosed systems During service, maintenance, or restoration, an optical fiber telecommunication system is considered unenclosed. Under these conditions, follow these practices: 1. Only authorized, trained personnel shall be permitted to do service, maintenance and restoration. Avoid exposing the eye to emissions from unterminated, energized optical connectors at close distances. Laser modules associated with the optical ports of laser circuit packs are typically recessed, which limits the exposure distance. Optical port shutters, automatic power reduction (APR), and automatic power shut down (APSD) are engineering controls that are also used to limit the emissions. However, technicians removing or replacing laser circuit packs should not stare or look directly into the optical port with optical instruments or magnifying lenses. (Normal eyewear or indirect viewing instruments such as Find-R-Scopes are not considered magnifying lenses or optical instruments). 2. Only authorized, trained personnel shall use optical test equipment during installation or servicing since this equipment contains semiconductor lasers. (Some examples of optical test equipment are optical time domain reflectometers (OTDRs), hand-held loss test sets). 3. Under no circumstances shall any personnel scan a fiber with an optical test set without verifying that all laser sources on the fiber are turned off. 4. All unauthorized personnel shall be excluded from the immediate area of the optical fiber telecommunication systems during installation and service. Consult ANSI Z136.2 American National Standard for Safe Use of Lasers in the U.S. or outside the U.S., IEC-60825, Part 2 for guidance on the safe use of optical fiber optic communication systems in the workplace.
