Electrical

Because an overhead projector is an electrical device, it might experience a short or fire when plugged into an electric socket. For example, you might cause the projector to short if, while drinking a beverage during your presentation, you accidentally spill some of it into the projectors air vents or another opening. Additionally, an electrical short or fire might occur if you use the equipment without getting it checked out after it falls, or neglect to repair it if it has a bad part, such as a frayed cord or damaged plug.
