Laser hazards
Hazards
The major hazards associated with the platesetter are laser radiation,
moving mechanical parts, and hazardous voltage electrical parts.
The platesetter has safeguards that reduce the risk of injury from laser
hazards.
Model MTA devices have one of the following thermal imaging heads:
TH2, TH3, TH6 or TH7.
The thermal imaging head has two lasers, which emit visible and
invisible high-powered laser radiation:
Visible (red) focus laser (Class 3b, approximately 660-680 nm)
●
Invisible (infrared) write laser (Class 4, approximately 808-830 nm)
●
Laser emissions from a thermal imaging head are invisible to the naked
eye and are very dangerous if they contact skin or eyes.
DANGER: Follow these guidelines to reduce the risk of exposing everyone in the
vicinity of the platesetter to laser radiation (directly from the laser system or from
the laser reflected on shiny or matte surfaces):
Do not operate the platesetter if you suspect that any part of the laser system
●
is defective.
Do not tamper with the interlock system on the access panels or the doors.
●
Do not attempt to open or to remove doors or panels while the platesetter is
●
exposing media.
Do not attempt to operate the platesetter with any doors or panels open.
●
Do not look directly or indirectly into the laser beam.
●
The thermal imaging head emits both visible and invisible high-powered laser
radiation as part of its normal imaging process. Even brief exposure to either type
of laser radiation can burn skin and can cause permanent degradation or loss of
eyesight. In the presence of flammable material, the laser beam is also a fire
hazard.
The platesetter is a Class 1 laser product. This means that if you comply
with the information in this guide, the platesetter's safety mechanisms
reduce the risk of harm from visible and invisible high-powered laser
radiation. The Class 1 laser product label, located below the power
switch at the rear of the platesetter, indicates compliance with
standards for laser safety.
