Many scientists involved with lasers agree on the following guidelines:      Everyone who uses a laser should be aware of the risks. This awareness is not just a matter of time spent with lasers; to the contrary, long-term dealing with invisible risks such as from infrared laser beams tends to reduce risk awareness, rather than to sharpen it, primarily due to complacency. Optical experiments should be carried out on an optical table with all laser beams travelling in the horizontal plane only, and all beams should be stopped at the edges of the table. Users should never put their eyes at the level of the horizontal plane where the beams are, in case of reflected beams that leave the table.

Brad Kelechava Leave a comment Lasers might be seemingly straight out of science fiction, but they are an actively-used technology in the world today. In fact, they have actually been around for a very long time. Interest in radiation was incredibly high at the start of the 20th Century from the discovery of radio, X-rays, and radar. The technology has been advancing ever since, having applications in communications, entertainment, surgery, and scientific advancement.
Most lasers are just amplifying light, but the frequency of each laser varies. Some kinds can be looked at directly without causing ocular harm, while others can be damaging from any kind of exposure. ANSI Z The standard sets guidelines for both the environment in which the laser is being used and any environment around the path of the beam.
While susceptibility to damage of materials is an important consideration with laser operations, the primary concern is the hazard to any person operating the equipment. These classifications are Class 1, Class 1M, Class 2, Class 2M, Class 3R, Class 3B, and Class 4, with Class 1 lasers being exempt from any kind of control due to their lack of hazard and Class 4 lasers requiring strict controls in order to reduce the risk of exposure to the eyes or skin.
The specific controls for each classification are thoroughly described in the standard. Since the use of lasers is essential for the operations of many much-needed technologies, securing the safety of the personnel of those operations makes them only more beneficial to society. Consumers need to be responsible with any laser products in their possession, even if they are labeled as Class 1.
