Risk Of Process By Product - Yueming MF20 Product Manual


It is a must to use the specified fuse provided by the manufacture;

Immediate pressing the emergency stop button is required in case of power failure;

Unless otherwise prescribed, power disconnection of the electric part is required for
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 electric machine. Timely correct failure like poor contact or
burnt power cord;

While operating live (charge) parts, minimum two persons are required at the site for
pressing the emergency stop button or disconnecting power supply if necessary; Mark
the working area with red-and-white band and warning sign;

It is a must to use insulation tools.

2.6.4 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 national standard
GB 18490-2001 laser processing machine. The abstract is as below:
A1.1 china processing
The oxide of Al O
2 3
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
Allergic reaction, burn caused by metal smoke
Lung fibrosis
carcinogenic
Metal beryllium is very dangerous, especially cutting alloy or metal containing Zn in
atmosphere will generate heavy metal smoke.
A1.4 plastic cutting
Various kinds of substances with potential risks may be generated when cutting the plastic.
At lower temperature, aliphatic hydrocarbon will be produced; at higher temperature, aromatic
hydrocarbon (e.g. benzene PAH) and polyhalo-polynuclear hydrocarbon (e.g. dioxin, furan) will
be increased. Some of these substances may possibly generate cyanide, isocyanate (PU), acrylate
(PMMA) and hydrogen chloride (PVC).
Medical influences include:
--------Toxic: Cyanide, CO, derivative of benzene
, Mg, Ca and Si; BeO (virulent).
