2.5.5 Risk of optical system
2.5.5.1 Routine operation
The reflector of the optical system is the gold plating silicon reflector, and the focus of the
cutting head is made from zinc selenide. ln normal condition, these optical parts are free of
danger.
However, polluted focus or focus with damaged coating will cause thermal decomposition
by laser beam over 400 'C together with toxic smoke generated. At this time, the laser device
must be powered off, mechanical movement and blowing air to the lens must be stopped. At this
moment, cleaning and parts replacement should be performed.
When gold plating silicon reflector is decomposed by high temperature laser beam due to
pollution or damaged coating. the decomposition will generate dust and smoke containing
silicone
monoxide, steam of heavy metal. At this time, it is a must to power the laser device off, stop
running the equipment and keep good ventilation. When all the smoke and dust are removed. it is
to perform cleaning and replacement of lens.
2.5.5.2 Warning for fire accident
Damaged machine or improper operation of the machine will cause risk of fire accident.
Fire extinguisher must be equipped according to Fire control regulations prescribed by the state.
2.5.6 0ther risks
To ensure safety, modification or changing use of the machine with no consent from the
Tips
·
Make frequent check on the ventilation system.
·
Make regular cleaning and maintenance for the ventilation system;
·
Foreign matter coming into duct of the ventilation system is strictly prohibited;
·
Ensure a good ventilation and a through removal of exhaust air in the working
room;
·
Ensure a necessary disposal of the exhaust air to satisfy emission requirements
prescribed by the state and local government
Tips: During cleaning please wear goggle and gloves. The damaged parts must be sealed in a
container and properly packaged, and then returned to the manufacturer.
Good ventilation is required in case of any damage of the parts.
Attention: Atomizer or flammable or explosive substances are strictly prohibited to
approach
the machine, make regular check on the fire extinguishers to ensure a good condition.
