Laser Pointer Safety Tips

• Laser pointers are designed to illuminate inanimate objects. Never shine a laser pointer toward any person, aircraft, or other vehicle.
• Never look directly into the beam of a laser pointer of any type.
• Do not allow children to use a pointer unsupervised. Laser pointers are not toys.
• If your telescope is equipped with a laser pointer that has a “constant-on” setting, do not leave the instrument unattended with the laser switched on.
• Do not aim a laser pointer toward mirrors or other shiny surfaces. The reflected beam may inadvertently strike someone in the eye.
• Do not aim a laser pointer in the direction of anyone using a telescope or binoculars for either astronomical or terrestrial viewing.
• Do not aim a laser pointer skyward if you hear or see an aircraft of any kind flying overhead.
• Do not use a laser pointer within 3 kilometres (2 miles) of an airport.
• The use of laser pointers is prohibited at some star parties and other astronomy gatherings. Always comply with such restrictions.
• Be aware of irresponsible uses of pointers so that the psychological effect will be minimized if you happen to be illuminated by one.
• Do not purchase a laser pointer if it does not have a “caution” or “danger” sticker on it identifying its class.
