Eye Safety Warnings

 

Avoid staring directly into the projector’s beam of light at all 

times.

 

Minimize standing facing into the beam. Keep your back to 

the beam as much as possible.

 

Using a stick or laser pointer is recommended to avoid the 

need for the presenter to enter the beam. 

 

Ensure that projectors are located out of the line of sight from 

the screen to the audience; this ensures that, when presenters 

look at the audience, they do not also have to stare at the pro-

jector lamp. The best way to achieve this is by ceiling-mount-

ing the projector rather than placing it on floor or table top.

 

When projector is used in a classroom, adequately supervise 

students when they are asked to point out something on the 

screen.

 

In order to minimize the lamp power needed, use room blinds 

to reduce ambient light levels.
