Appendix A: Laser Safety Guidelines
Under normal operating conditions, optical fiber telecommunication
systems are completely enclosed; nonetheless, observe the following
precautions:
•
Do not stare into optical connectors or broken fibers.
• Ensure technicians have satisfactorily completed an approved
training course before performing installation or maintenance.
• Ensure there are appropriate warning labels near the optical ports of
the modules.
Precautions for Unenclosed Systems
During service, maintenance, or restoration, an optical fiber
telecommunication system is considered unenclosed. Under these
conditions, follow these practices:
•
Avoid exposing the eye to emissions from unterminated, energized
optical connectors at close distances.
• Ensure that only authorized, trained personnel use optical test
equipment during installation or servicing.
• Turn off all laser sources before scanning a fiber with an optical test
set.
• Keep all unauthorized personnel away from the immediate area of
the optical fiber systems during installation and service.
CAUTION
Only authorized, trained personnel shall be permitted to do service,
maintenance, and restoration.
For guidance on the safe use of optical fiber communication systems in
the workplace, consult
ANSI Z136.2, American National Standard for
Safe Use of Lasers in the United States. Outside the U.S., IEC-60825,
Part 2 applies.
