For even more protection all students should carry a Personal Alarm with them at all times. This device is activated by pulling a pin or pressing a button. This will immediately sound a very loud alarm which will startle an attacker as well as get the attention of anyone around. And since most college students have cell phones, it will give them a chance to call 911, get a photo or two or maybe even get some video of what went on.
Personal Alarms are small and inexpensive and come in different shapes with different alarm intensities. There is one particular device that is great for coeds – a lipstick alarm which looks like a stylish tube of lipstick but gives off a 100 db alarm which can be heard by anyone nearby.
