Rape alarms, also known as personal safety alarms, are small, portable devices designed to emit a loud, piercing sound when activated. These alarms are intended to deter potential attackers and attract attention, and may provide individuals with a sense of security. However, they do not guarantee protection from an attack.

The need for rape alarms

Interest in rape alarms reflects concerns about personal safety and the persistent issue of sexual violence. Police recorded 67,928 rape offences in England and Wales in the year ending March 2024. This does not capture the full extent of sexual violence: ONS survey findings cited in the same release indicate that fewer than one in six victims of rape or assault by penetration reported it to the police.

Some people may find a personal safety alarm useful in public spaces, such as parks, streets, and public transportation, where they might feel vulnerable. The loud noise is intended to draw attention and may deter an attacker. Carrying an alarm may also provide reassurance, but its effectiveness depends on the circumstances, including whether anyone nearby hears it and responds.

How they work

Personal safety alarms are designed to be simple to use. Many devices are small enough to be carried in a pocket or attached to a keychain. When activated, typically by pulling a pin or pressing a button, the alarm emits a loud, high-pitched sound. This sound may startle an attacker and alert passersby to the individual’s distress.

Some alarms include additional features such as LED lights, which can help in dark environments. Separate personal safety apps and connected devices may offer location-sharing features. A standard audible alarm does not automatically notify the police or emergency services.

Where to find a rape alarm

Some universities and students’ associations distribute personal safety alarms for free. For example, the University of Kent offers free alarms through its Campus Security team. Availability varies, so check with your university or local community organisation.

There are also multiple websites selling the gadgets.

While personal safety alarms may help attract attention and provide peace of mind, they are not a comprehensive solution to sexual violence. Responsibility for an assault always rests with the perpetrator, regardless of whether someone carries or uses an alarm.
