A personal security alarm is extremely loud and is intended to shock and disorientate an attacker, giving you time to get away and call for help. It can also help you attract attention, when it matters most. They are small enough to fit into a hand, yet the ear splitting high pitched sound they emit (usually 120 decibels or more), is very uncomfortable to listen to for even a few seconds.
There is a wide range of loud, compact and versatile personal security alarms available on the market. No matter which one you chose it should be easy to carry and easy to reach if you ever need it and you should be able to operate it comfortably and quickly.
Is a personal security alarm enough?
You should not rely on a personal security alarm on its own as a way to attract help — there might not be anyone around to hear it, and even then it might be ignored or mistaken for a car alarm. A personal security alarm should be one part of your overall personal safety plan, and you should always be aware of your surroundings when out alone, especially at night.
