Laser cutting harm to human body and protective measures

Published:2020-11-04 Browse:6Editor in charge:DNE Laser (Member of Bystronic)


In recent years, laser cutting machines have become the new favorite of the metal material processing industry, and are gradually widely used in the metal industry. The high efficiency of laser cutting technology has greatly promoted the transformation and upgrading of domestic industrial technology.


However, while enjoying the high efficiency and beauty of laser cutting, how to do safety protection in use to make the equipment perform better and reduce the radiation to the human body?


Protection of the respiratory tract

The high temperature generated by the laser cooperates with the gas to complete various processing, and at the same time, it also generates a large amount of dust. Especially when processing some special metal materials, the dust generated contains some chemical components, which can cause harm to the human body when inhaled.


Therefore, when performing laser cutting work, it needs to pay attention to the protection of the respiratory tract. Meanwhile, installing the supporting dust removal device, people should try to operate in an unobstructed air environment, and try to wear a mask. Do not touch the cut parts immediately to avoid burns due to residual temperature.


Eye protection

The laser cutting machine can cause damage to the retina or cornea of the eye when it is working. When arranging the cutting site, the following measures can be taken to reduce the reflection or radiation of ultraviolet rays:


1. Darken the wall paint on the worksite to reduce radiation;

2.Install protective screens or curtains to reduce ultraviolet radiation;

3.Wear protective dark glasses or goggles, or welding helmets to protect the eyes from the strong light of the flame, the ultraviolet and infrared rays of the plasma arc;

4.Other people in the work area should not look directly at the arc or flame during cutting.


Skin protection

Laser cutting has certain damage to the skin tissue, and this damage can be repaired by itself. It should be noted that long-term exposure to laser light can cause skin burns or scars. Therefore, when performing laser cutting work, the protection of the skin must also arouse great attention.


For safety reasons, it is recommended that laser operators should wear long-sleeved clothing to prevent the laser from directly hitting the skin to cause skin burns, and to prevent molten slag splashing on the skin and causing burns. Do not touch the cut parts immediately, wear gloves to avoid burns due to residual temperature.
