Precautions for Handling
Laser Safety Supervisor
⇒
Appoint a safety supervisor for all laser work.
The appointed safety supervisor must have su󰀩cient knowledge and experience
regarding both lasers and laser work.
⇒
The supervisor must control the keyswitch of the Laser, and must be responsible
for instructing operators in safety aspects of the Laser as well as directing the
laser work.
⇒
Establish and control a laser operation area.
The responsible person must isolate the laser operation area from other areas
and control it by fences and display signs indicating that the area is o󰀨-limits to
unauthorized personnel.
Routine Handling
⇒
Perform inspection periodically referring to the Maintenance Part, Chapter 1 "1.
Maintenance Parts and Standard Intervals of Inspection/Replacement" on page 145.
⇒
If the outside of the Laser is stained, wipe it with a dry cloth or a moistened cloth.
If it is badly stained, use neutral detergent or alcohol to clean it. Do not use
paint thinner, benzine, etc. which can discolor or deform the parts.
⇒
Do not put screws, coins, etc. in the Laser, since they can cause a malfunction.
⇒
Operate the switches and buttons carefully by hand. If they are operated
roughly or with the tip of a screwdriver, a pen, etc. they may be broken.
⇒
Operate the switches and buttons one at a time. If two or more of them are
operated at a time, the Laser may have trouble or may be broken.
⇒
The outer panels and the covers are electrically connected to the main unit
by connecting cables. When the panels, covers and connecting cables are
removed and installed again, make sure that all these components are put back
into place correctly. Also, make sure that the cables do not block the optical path
of the oscillator or get caught between the outer panel and the frame.
⇒
To prevent damage, do not bend the optical ber beyond its minimum bending
radius or apply any forms of shock to it. For the ber’s minimum bending radius,
see the table below.
Minimum bending radius of the optical ber
Core Diameter Minimum Bending Radius
φ 0.2, 0.3, 0.4 mm 100 mm
φ 0.6 mm 150 mm
φ 0.8 mm 200 mm
φ 1.0 mm 250 mm
⇒
When a supervisor or operator enters the area where the laser is used,
protective measures not to exceed the MPE* level must be taken.
* MPE: The maximum level of permissible exposure of the eyes or skin to laser beams. Abbreviation of
Maximum Permissible Exposure.
* For other information on managing laser equipment or the MPE level, refer to the
following standards.
