Safety Practices for Class 3a and 3b OFCS Only authorized-trained employees may: Install Service Maintain fiber-optic systems that are not enclosed.

Slide7: 

Non-beam Hazards of Optical Fiber Communication Systems Glass Particles- Avoid contact with small pieces of glass fibers. Fusion Splicing- Refers to joining the Fibers together at the ends by a heating process. Solvent/Chemicals- Solvents used while working with FTTP include isopropyl alcohol.

Slide8: 

LASER Eye Protection Eye protection devices, which are specifically designed for protection against the optical energy from a Class 3b OFCS, should be administratively required when engineering or other procedural administrative controls are inadequate to eliminate potential exposure in excess of the applicable Maximum Permissible Exposure (MPE).
