z All the operation shall be performed by authorized personnel who satisfactorily completed an
approved training course.
z Make sure that the optical source is switched off before disconnecting optical fiber connectors.
z Before opening the front door of an optical transmission system, always take care that you are not
exposed to laser radiation.
z Never look into the end of an exposed fiber or an open connector as long as you are not sure
whether the optical source is switched on or off.
z Please use optical power meter to check that the optical source is switched off by measuring the
optical power.
z Never use optical instrument such as a microscope, magnifying glass or eye loupe to view the
optical connector or fiber.
Handing Fibers
Read the instructions before handling fibers.
z Cutting and splicing fibers must be performed by trained personnel only.
z Before cutting or splicing the fibers, always verify the fiber is disconnected from the optical source.
After disconnect the fiber, all the optical connectors must be protected by a protecting cap.
Working at Heights
When working at heights, be cautious to prevent objects from falling.
High-altitude work should comply with the following requirements:
z High-altitude operators must be trained.
z Operating machines and tools should be carried and handled safely to avoid falling.
z Take safety protection measures like wearing helmet and safety belt.
z In cold areas, heat-retaining clothes should be worn before high-altitude operation.
z All lifting appliances should be checked before high-altitude operation.
The Safety Codes on Ladder-using
Before using the ladder, first check if the ladder is damaged. Make sure the ladder is safe for use.
Overweight on the ladder is strictly prohibited.
The slant of the ladder is 75
° at best. The slant can be measured with Angle Square or with arms. When
a ladder is used, the wider end of the ladder should be placed against the ground or protective
measures should be taken on the base part of the ladder for the purpose of skid resistance. Place the
ladder against a stable ground.
When climbing the ladder, one’s center of gravity should not deviate from the ladder edge. To lessen the
danger and ensure safety, three parts of the body should be on the ladder. When climbing the ladder,
the upper limit of the height should not exceed the highest four steps. If one is about to climb to the top,
the length of the ladder should be 1 meter higher than the eave
