precautions while using overhead projectors

Stand off to one side of the overhead projector while you face the audience Too many people stand between the overhead projector and the screen causing a shadow of the presenters body. Standing to one side will allow the audience to see you as the presenter and will prevent you from blocking their view of your visual aid.

Face your audience and not the screen. Many presenters face the screen and end up talking to the screen. Although overhead projector designs vary by manufacturer, design elements shared across manufacturers can pose certain dangers to you and your audience.

With an opaque piece of cardboard (I usually mount a solid sheet of paper on one of my transparency frames). You may also turn off the projector completely, but beware, this can cause the projector bulb to burn out sooner. Overheating of projectors might cause melting of different parts of the device. This may lead to exposure of toxic smokes. If you are taking drinks or any beverage during the presentation, make sure that the projector is far off the glass.

Nothing is more unsettling than to have your overhead projector bulb burn out during your presentation. Bring spare bulbs and a glove to change the bulb. The old bulb will be HOT! Make sure you know how to change the bulb. CAUTION: Remember HOT glass looks the same as cold glass.
