DO NOT SHINE DIRECT BEAM IN EYE-BLINDNESS HARZARD! The direct beam at close distance can cause instant blindness. The direct beam up to 250m/750ft can cause eye damage. Never aim any laser towards a person's head, or where a person may suddenly appear. Never aim towards a pet or other animal. |

DO NOT GET REFLECTED BEAM IN EYE The beam reflection can cause instant eye damage, especially at close range. There are MANY shiny or smooth objects that can reflect a laser beam. ALWAYS be aware of both the main beam AND its reflection(s). Be especially careful when aiming out of windows due to danger from the "back reflection". |

AVOID EXPOSURE TO BLUE LIGHT Blue laser light can cause photochemical eye damage. Avoid prolonged exposure to blue light (light from 530nm green to 380nm ultraviolet can be hazardous, with the peak danger at 440nm blue). There is a hazard even from prolonged exposure to diffused "room glow" from the beam reflecting off walls or other surfaces. Use safety glasses that block blue light. |

WEAR SAFETY GLASSES If available, wear laser safety glasses or googgles. They MUST be appropriate for your laser's power and wavelength, so the laser beam's power is safely reduced. However, DO NOT RELY ON THE SAFETY GLASSES ALONE. Continue to avoid direct and reflected exposure to the beam. |

DO NOT LOOK OR STARE AT DIFFUSED RELECTIONS Looking at the laser "dot" can cause eye damage. Danger is higher when on white surfaces and at close range. DO NOT USE THIS AS A LASER POINTER. |

DO NOT BURN OR DAMAGE MATERIALS The beam can char, burn or ignite materials. Especially avoid dark, thin, and combustible materials such as fabrics. |

DO NOT SHINE BEAM ON SKIN - BURN HAZARD The direct or reflected beam can burn exposed skin. Wear protective, light colored clothing. Do not aim beam at your skin, skin of other persons, or animals. |

DO NOT AIM AT AIRCRAFT OR STARS The bright light from many of our lasers can flash blind or distract a pilot. NEVER AIM ANY LASER TOWARDS AN AIRPLANE OR HELICOPTER. Always be careful any time the beam goes into the sky. Since far-away aircraft can look like stars, DO NOT USE FOR STAR POINTING. Only use Class 2 or Class 3 lasers for astronomy star pointing purposes. |
