Pretoria Centre of the Astronomical Society of Southern
Laser safety rules and guidelines applicable to ASSA
Pretoria Centre events
- ASSA Pretoria reserves the right to control the use
of laser pointers at their events.
- Only registered laser pointers, up to a maximum of
20mW output, will be allowed.
The following ‘best practices’ will apply at events:
- Laser pointers should only be used by experienced
- Do not point at people, aircraft or animals
- Keep a suitable distance from the audience
- Warn the audience not to look directly at the laser
- The area around the user must be clear of obstacles
- Avoid pointing at surfaces that can give specular
- Minimize the use of laser pointers (do not play)
- Do not allow children to operate laser pointers
- Do not use mechanisms that keep the pointer switched
- Laser pointers belonging to users not adhering to
may be confiscated (the laser will be returned after the end of the
event), and/or the offender may be barred from participating further.
The following “good manners” are advised:
- Be considerate of others.
- Laser pointers do ruin your eye’s dark adaption.
be busy with serious observations and will prefer not to have a laser
pointer shining in the area that they are observing.
- Someone may be doing long exposure photography. A
laser pointer shining in the target area can spoil a lot of work.
- To avoid inconveniencing your fellow astronomers,
warn everyone before you use your laser pointer.
- Wait until everyone agrees that it is appropriate to
use the pointer.
- The same principles applies to any form of lighting
(torches, cameras, cell phones, etc).
