    1-4. Eye Safety Warnings 1. Avoid staring directly into the projector’s beam of light at all times. 2. Minimize standing facing into the beam. Keep your back to the beam as much as possible. 3. 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 projector lamp.
