Only use light bulbs equal to or less than the rated capacity of the fixture. Doing so creates a fire hazard and premature failure of the fixture as wires overheat and oxidize. Most residential hall light fixtures are rated at 60 watts. Open flame, including candles, can lead to a dangerous fire. Dispose of all wastes as soon as possible.
Fire is yet another health risk that smoking can create.
Familiarize yourself with fire evacuation procedures for your building or residence hall.
