Eye Safety Warnings
ɼʄAvoid staring directly into the projector’s beam of light at all times.
ɼʄMinimize standing facing into the beam. Keep your back to the
beam as much as possible.
ɼʄUsing a stick or laser pointer is recommended to avoid the need
for the presenter to enter the beam.
ɼʄEnsure that projectors are located out of the line of sight from the
screen to the audience; this ensures that, when presenters look at
theaudience,theydo not also have to stare at the projector lamp.
The best way to achieve this is by ceiling-mounting the projector
