1 DANGER Laser Radiation and High Voltage/Electrical Shock The ILRIS-LR is an inherently dangerous system: Follow safety instructions carefully and consider safety issues at all times. Before operating or servicing the ILRIS-LR, read and understand this manual. When handling the system, recognize and obey all hazard labels and information. The ILRIS-LR emits laser radiation that can permanently damage eyes. Operation and servicing must be performed by trained and qualified personnel only. Voltages in the ILRIS-LR can be harmful and even lethal. When servicing any part of the ILRIS-LR, follow standard high voltage precautions or confirm that the system is powered off. Disclaimer and Limitation of Liability Optech Incorporated assumes no responsibility for any damage, loss, or other claim incurred by an end user or any third party arising or resulting from the use of this instrument or its associated software. Shipping Damage This unit is inspected before shipment. As soon as the unit is received from the carrier, and before operation, inspect the unit for damage that may have occurred during shipment. If any damage is found, file a claim promptly with the carrier and notify Optech immediately.

Notice Class 3B laser product Complies with IEC , edition 1.2 and FDA performance standards for laser products except for deviations pursuant to Laser Notice No. 50, dated July 26, The ILRIS scanner emits invisible laser radiation, and is designed to be a Class 3B, 3R, or 1M laser product, as defined by IEC The exact class of the ILRIS scanner depends upon the range at which it is viewed and whether the ILRIS is firing in Enhanced Range (ER) mode. Table 2: Laser class by range and mode 0-25 m m > 114 m ER mode ON Class 3B Class 3R Class 1M ER mode OFF Class 1M Each of these classes poses a potential for harm, as follows: Class 3 (3B or 3R) Can cause harm when viewed directly. Class 1M Can cause harm when viewed directly through optical instruments such as binoculars or telescopes. This radiation is eye-safe if not viewed through optical instruments /Rev A.0/Nov 10 3

3 Handling and Safety ILRIS-LR Operation Manual Because Class 3 lasers can cause irreversible eye-damage when viewed directly, the nominal ocular hazard distance (NOHD) for unaided viewing of the ILRIS laser scanner in ER mode is 114 meters. It is the operator s responsibility to prevent harm to themselves and bystanders by following the safety precautions in this chapter. Table 3: Incorporated laser specifications Parameter Wavelength Pulse width Pulse energy Average power Pulse repetition frequency Specification 1064 nm <10 ns <10 J 100 mw 10 khz Enhanced Range mode When the ILRIS scanner is in ER mode, it is considered a Class 3 laser product at ranges up to 114 meters, and a Class 1M laser product at ranges beyond that. By definition, a Class 3 laser can cause irreversible eye damage when the beam is viewed directly. Therefore, there is a non-eye-safe zone in the beam path within 114 m of the scanner, as shown in Figure 1. Note that the non-eye-safe zone extends ±20 (40 total) from the heading of the ILRIS, both horizontally and vertically /Rev A.0/Nov 10

4 ILRIS-LR Operation Manual Handling and Safety Figure 1: Laser beam path and classification in ER mode To prevent eye damage, follow these safety precautions when firing the ILRIS in ER mode: Scanner placement Place the ILRIS where there is the least chance of bystanders entering the non-eyesafe zone. For instance, avoid firing the laser across a road or a hiking trail, if possible. It may be helpful to have another operator monitor the beam path and alert you if anybody enters the non-eye-safe zone. Monitoring Always remain by the scanner while it is firing, and be ready to turn off the scanner if anybody enters the non-eye-safe zone. You can turn off the laser by clicking Stop the in the Scan Progress window (see page 139 for the Pocket PC Controller, or page 206 for the PC Controller). In an emergency, you can also turn off the laser by turning the laser interlock key 90 counterclockwise. Turning off the laser with the key will not usually cause the ILRIS to lose survey data /Rev A.0/Nov 10 5

5 Handling and Safety ILRIS-LR Operation Manual Eye protection If anybody needs to stand in or near the non-eye-safe zone, they must wear eye protection that has an optical density (OD) of at least 4 at a wavelength of 1064 nm (about 1 m). Even with eye protection, they must not look directly into the beam. Reflections Make sure there are no highly-reflective surfaces in the non-eye-safe zone. While the beam is too weak to cause harm when returned from matte surfaces such as foilage or concrete, it maybe still cause eye-damage if returned from highly-reflective surfaces such as mirrors. Beyond the non-eye-safe zone Even when the ILRIS is viewed beyond its NOHD (114 m), it is still considered Class 1M. As a Class 1M laser, it can still cause harm if viewed directly with optical instruments such as binoculars or telescopes, because these devices concentrate the power of the beam. Do not view the beam directly with such instruments. Pan/Tilt base The path of the laser beam extends ±20 from the heading of the ILRIS, both horizontally and vertically. However, because the Pan/Tilt base can change the heading of the ILRIS during a scan, it can make the non-eye-safe zone even wider. If you use the Pan/Tilt base, apply all the usual safety precautions to the widened non-eye-safe zone. Furthermore, it is strongly recommended that all operators wear eye protection while the ILRIS is firing on the Pan/Tilt base. Motion compensation Safety is especially important when performing mobile scanning with the motion compensation (MC) option, because the zone moves along with your vehicle and therefore covers a much larger area. If at all possible, do not move your vehicle closer than the NOHD (114 m) to any place where bystanders could be. Alternatively, restrict access to the area that you plan to scan so that nobody can enter the area.! Note In MC mode, the ILRIS does not move the laser beam from side to side, just up and down. Therefore, the non-eye-safe zone only extends ±20 vertically from the heading of the ILRIS, not horizontally /Rev A.0/Nov 10

6 ILRIS-LR Operation Manual Handling and Safety With ER mode turned off When the ILRIS is firing with ER mode turned off, it is considered a Class 1M laser product at all ranges. Because radiation from a Class 1M laser can cause harm when viewed directly with optical instruments such as binoculars or telescopes, do not view the beam with such instruments. If viewed without optical instruments, the ILRIS is eye-safe when firing with ER mode turned off. Removing the scanner panels The ILRIS incorporates a Class 3B laser (IEC ). Under certain conditions, removing scanner panels gives access to emission levels in excess of Class 1M eyesafe limits, even when the ILRIS is not firing in ER mode. Therefore, removing the panels may increase eye hazard. Do not remove the scanner panels. Opening the scanner will void the warranty, and there are no user-serviceable parts inside. Hazard labels The following labels and tags are attached to the ILRIS. Figure 2: Laser Class 3B caution label Figure 3: Laser Class 3B caution label on front of ILRIS /Rev A.0/Nov 10 7

Always handle the scanner carefully as follows: 1. When the scanner is powered, do not lay it on its side. 2. Do not touch the front scan window. 3. Do not immerse the scanner. The scanner is splash/dust-proof to NEMA Do not open the scanner. There are no user-serviceable parts inside. 5. The scanner is heavy. Lift and move it with care, and do not drop it. Opening the scanner will void the ILRIS warranty /Rev A.0/Nov 10
