2.2 Hazard Sources
2.2.1 Beam Hazard
The high temperature caused by the laser radiation can instantly coagulate or vaporize
proteins, thereby causing damage to biological tissues.
The most vulnerable parts of human body are eyes and skin.
Of all organs of the human body, eye is the one most vulnerable to laser. The IR radiation
emitted by the laser is very harmful to the human eye. It will burn the retina, causing loss of
vision and even blindness. It is essential that you wear qualified and safe safety goggles
