In today's world, we are on the various types of light use purposes arebecoming increasingly lacking, however, still can not prevent the laser light on us to purify, wearing a Laser safety glasses to continue to protect. We shall not make eye contact laser, and only light purification will let our eyes blind, purify the wearing of Laser safety glasses are insufficient protectionof laser cutting urgently, we yesterday for everyone to talk about the greatharm to our laser purification.
Laser installation on the human body and operating conditions caused by the harmful effects of the laser damage, known as the laser damage to the insurance measures taken by the laser protection. From the damage of laser installation can be divided into radiation damage, electrical damage, chemical damage and mechanical damage of class four, usually only think of radiation damage. Laser radiation can cause hurt to human eyes and muscles, which are the most important antecedents of previous. Because the human eye is on the opposite of the laser transmission span and attract the opposite, opposite span laser to eyes were also injured instead (see [the human eye to electromagnetic radiation shows the intention to attract]). The laser radiation caused by eyeinjury caused by important light solidification, keratitis, corneal perforation, lens opacity, carbonization and visual performance of "bright blind", and hinder the omental solidification, suppuration and bursting. Laser radiation hurt caused by muscle important pigmentation, erythema and blisters. Slander lies on the size of the dose level of radiation, which has nothing to do with the laser input energy, operation span and operation state, which is the most important component of energy. To the human body and operating conditions of theformation of damage not only direct light, but also a reflection of light and diffuse light. Continue to laser processing and laser treatment, may produceharmful smoke, steam and noise, etc., to the conditions of radiation damage. High power laser radiation can destroy some fine instruments, and even lead to fire.
The laser to cause harm is very big, we also have a hard time to remove unwarranted. Only in the laser operation, ability to do protective measureson the laser from the laser cut.
