The invisible ultra-violet pulses of coherent light emitted from this laser are capable of
inflicting permanent eye damage and total blindness. The beam can burn skin tissue and may
cause ignition of chemicals on some common materials. If at all possible, laser work should be
performed in a light tight enclosure with safety interlocks.
Electrical hazards (e.g. electric shock) may occur from contact with exposed power
supply or device control conductors operating at potentials of 50 V and above. These exposures
can occur during laser set-up or installation, maintenance and service, or any other time when
equipment protective covers are removed to allow access to active components.
Air contaminants may be generated when Class IV laser beams interacts with matter.
When the target irradiance reaches a given threshold (10

W/cm

), target materials including
plastics, composites, metals and tissues may liberate airborne contaminants such as metallic
fumes and dust, metallic oxide fumes, chemical and gaseous vapours, etc. Some of the
compounds include: polycyclic aromatic hydrocarbons from poly-(methyl methacrylate) type
polymers, hydrogen cyanide and benzene from aromatic polyamide fibres, benzene from
polyvinyl chloride, fused silica from quartz, etc. Three major control measures to reduce the
concentration of air contaminants are exhaust ventilation, respiratory protection, and isolation of
the process.
To operate the M100LFG-TT-A in a safe manner:
•
Permit only authorized personnel to operate the laser.
•
Ensure that all personnel wear adequate eye protection during laser maintenance.
•
Install appropriate signs and labels at site of laser operations.
•
Use a continuing laser safety educational program for personnel operating the system
or others in the vicinity of the laser.
•
Enclose the entire laser beam path when possible.
•
Do not to operate without protective covers.
•
Do not work with unenclosed laser beams at nominal mode.
•
Do not exceed limit laser parameters specified in manual.
•
Use beam shutters and laser output filters or beam traverse and elevation stops to
restrict beam interception on outdoor devices.
•
Use dark, absorbing, diffuse fire-resistant targets and backstops where feasible. Avoid
exposure to scattered laser light reflected from optic elements, beam splitters,
entrance windows, beam analyzers, etc.
•
Do not operate without grounding.
•
Do not to introduce any changes into electric line or power supply.
•
In the event of medical emergency, contact a doctor immediately.
