maintenance;
> First check if there is live power on the insulated part, and then perform the treatment of
earthing and open circuit, and perform insulation for the nearby live (charge) parts;
> Make regular check on the fiber laser marking machine. Timely correct failure like poor
contact or burnt power cord;
> While operat ing live (charge) parts, minimum two persons are required at the site for
disconnecting power supply if necessary; Mark the working area with red-and-white band
and warning sign;

2.6.5 Risk of process by product
During laser processing, outgrowth may possibly generate, and their hazard must satisfy
the requirements specified in Appendix A for example of processing outgrowth as China
national standard GB 18490-2001 laser processing machine. The abstract is as below:
A1.1 Ceramic processing
The oxide of Al2O3, Mg, Ca and Si; BeO (virulent).
A1.2 Silicon slice processing
Crumb of silicon and silicon monoxide suspended in the air (possibly breathed into lungs
causing silicosis);
A1.3 Metal processing
In a view of medicine, the following metals and their compounds are influential: Mn, Cr,
Ni, Co, Al, Zn, Cu, Be, Pb, Sb
Medical influences are as below:
Toxic Cr6-, Mn, Co
Allergic reaction, burn caused by metal smoke Zn, Cu
Lung fibrosisBe
carcinogenic
Cr6+, NiO
Metal beryllium is very dangerous, especially cutt ing alloy or metal containing Zn in
atmosphere will generate heavy metal smoke.
A1.4 Plastic marking
Various kinds of substances with potent ial risks may be generated when cutt ing the
