GB18217—2000
This standard is formulated for the purpose of normalizing and standardizing the use of laser safety signs for laser products and in places with laser radiation. This standard stipulates the design, size, color, graphics, text, etc. of laser safety signs for laser products and in places with laser radiation, and provides guidance on the use of signs on products and in laser places. Except for special requirements of users of imported and exported products, the requirements of this standard should be followed.
At present, many users, maintainers, manufacturers and bystanders of laser devices or laser equipment in my country do not understand the dangers of possible personal injury when being exposed to the true radiation, reflection and scattered light of laser in some cases. There are serious phenomena such as not setting up low-light safety signs in production and application places, and confusing the provisions of radiation safety classification signs used on laser products with safety signs used in places with laser radiation. The formulation of this standard will fundamentally solve these problems. This standard is proposed and managed by the State Economic and Trade Commission. The drafting units of this standard are Beijing Institute of Optoelectronic Technology and Labor Protection Testing Technology Center of the State Economic and Trade Commission. The main drafters of this standard are Man Chunyang, Li Zhongxiang, Lu Yaodong and Jiao Long. Beijing Institute of Optoelectronic Technology and Labor Protection Testing Technology Center of the State Economic and Trade Commission are responsible for the interpretation of this standard. 455

5 Materials for making signs
The materials for making laser safety signs should meet the requirements of different use environments. Use durable and waterproof materials, and avoid using materials that are easy to fade and flammable after exposure to light.
6 Use of signs
6.1 Use of laser product safety signs
6.1.1 All laser products that may reach Class 2 must have a laser safety sign. Each device must also have a laser warning sign, a laser safety classification description sign and a laser window sign (see Appendix A for examples of the use of laser product safety signs). 6.1.2 The laser safety sign must be pasted in a place where personnel can see it clearly without being exposed to more than Class 1 radiation. The laser classification sign should be placed directly below the laser warning sign, and the laser window sign should be placed near the laser light outlet (Class 3 and Class 4 laser products should have window signs pasted on all openings that may reach Class 2 laser radiation). 6.1.3 If the size or design of the laser product is not convenient for installation, the sign should be provided to the user as an attachment. 6.2 Use of safety signs in laser workplaces 6.2.1 Laser safety signs must be placed in all places where Class 3B and Class 4 optical products work. Laser warning signs can be used alone, or laser warning signs and laser radiation site safety classification signs can be used at the same time. In this case, the laser radiation site classification sign should be placed directly below the laser warning sign.
6.2.2 Laser safety signs should be set up in places where Class 3A laser products are used for measurement, alignment, and leveling. 6.2.3 The laser safety sign must be pasted in a conspicuous position in the laser protection area, so that personnel can notice the sign and know the content displayed without being exposed to more than Class 1 radiation. When the signs cannot cover the entire working area, multiple signs should be set. 6.2.4 Permanent laser protection areas should be equipped with laser safety signs at the exits. In temporary protection areas surrounded by movable baffles and guardrails, in addition to laser safety signs at the entrance, laser safety signs must also be set at each movable part or maintenance joint of the protective fence and baffle to prevent personnel from being exposed to harmful laser radiation when these plates are separated or the joints are disconnected. 7 Inspection and maintenance of signs
7.1 The low-light safety signs should be inspected at least once every six months. If fading, damage, deformation, etc. are found, they should be repaired or replaced in time. 7.2 When repairing or replacing laser safety signs, temporary signs should be replaced to avoid accidental injuries. 460
