Hong Kong Medical Terms for a set of laser equipment for medical laser equipment. A focus on laser safety working group of the Hong Kong Government. Laser Safety Code of Practice was published in 1991. Laser safety classification of safety measures for the development of appropriate protective measures to provide a great convenience, in principle, the higher the level, the more stringent protection requirements. In fact, if the laser device is designed as a closed, all shielded light source and the laser path, so you do not there is any danger, shall be guilty of a level of security. However, if not designed to be fully enclosed, you must provide to the operator safety training and hazard control measures. Laser class safety standards. Such as creating some romantic atmosphere generated by green laser pointer in the dark night.
Safety standards for the two laser directly into the human eye exposure is prohibited, prohibited directly into the human eye exposure, no other protection requirements. The class must have security measures protective measures. Requirements. Over 2 must have safety precautions. Three or four laser devices can not be designed to fulfill closed, should also be shielded by the optical path, such as pipes, separators, hood, etc., to minimize laser damage to the eyes of the operator. If not all three or four laser device designed to be closed, should be specified in the workplace laser danger zone, limiting the number of people into the area. Into the laser beam in the danger zone must wear laser goggles. The perfect parameter and high cost performance of green laser pointer are also the big selling point.
More parallel to the laser in the majority of research laboratories. The danger zone for the experimental control area, the less the scope to use the occasion of the focused laser beam device, do not include the entire room. The majority of laser devices sold in the urban surface control lock to prevent the misuse or abuse of the device in the unprotected conditions. Not required to use the laser device should be closed to non-operator can not be opened. Start-up and calibration of laser equipment which makes the eyes damaged, they need to take special protective equipment. Laser goggles are designed in accordance with the provisions of the occupational exposure limit, its protective properties of said optical density (or ODs, ie, the shading coefficient of the logarithm of). The body of green laser pointer is metallic with the rubberized finish.
It reflects the functional relationship of a particular laser wavelength and exposure time. Regulations on the protection of the eyes (laser) in Europe, the U.S. national standard in the ANSI Z-136.1 and ANSI Z-136.3 provisions would have more detailed provisions. Training in research laboratories and factories in the laser accident, after investigation to have a common drawback: the lack of operator safety and technical training. Laser Safety Training for the type of instrument and its design uses object is the operator of the laser device. Laser Measurement generally do not need to laser radiation in the workplace monitoring dangerous levels. This is very different from the provisions of other risk factors. This kind of green laser pointer can be used to point at any desired targets.
Due to the laser beam is highly directional, and can not arbitrarily change the optical path, the laser radiation detector is expensive, complex structure, the general safety requirements are not subject to on-site monitoring, but to emphasize the danger level of control the laser device, it should be equipment suppliers responsible for the determination of whether the devices comply with the standard. Conclusion Despite the short history of laser applications, but most users are taking safety precautions when using. The key requirement is the use of laser, the use of closed-end devices, and otherwise must be provided to the operator safety training and the use of protective measures.

ICE60825.1: 2001 laser safety rating Class I: low-output laser (power less than 0.4mW). Laser beam wavelength of green laser is 532nm.
