The maximum allowable power output in a rotating construction laser is 5 milliwatts or less. A milliwatt is 1/1000th of a watt, a very small amount of power. The light is concentrated however, and the following precautions should be taken when using such an instrument: Do not stare into a laser beam or view it directly with optical instruments. Do not disassemble the laser or attempt to service it. Do not use the laser until you have read the instruction manual and you are familiar with the operation of the instrument. Infra-red beam lasers are designated class 1 laser products. No jobsite warning placards or operator certification cards are required. No Product warning labels are required on the laser. These meet class 1 requirements under the 1993 IEC 825-1 laser safety standard and the revised edition of the European Norm EN60825. The L1-ASm Magnum, L4, L4+, L3, and L5 lasers are designated class II or IIIa under the 1993 IEC 825-1 laser safety standard and the revised edition of the European Norm EN60825. They conform to applicable EC directives regarding RFI and EMI. US OSHA requires that a jobsite warning placard must be posted in the work area, and laser operator must carry proof of qualification. Only qualified and trained employees are to install, adjust, and operate the laser. The laser should be set up above head level and never intentionally aimed at anyone. The laser should be turned off when not being used. |
