Definition of Panic Button (Duress Alarm)

A panic button, also called a duress alarm or SOS button, is a manual alert that a worker triggers when they are threatened, injured or in danger and need help immediately. It can be a dedicated wearable, a fixed button under a counter, a feature in a two-way radio or satellite device, or a button in a lone worker safety app. When pressed, it sends an alert, usually with the worker's GPS location and identity, to a monitoring center, supervisor or emergency contacts, who then follow a predefined response.

Panic buttons are most common in lone and remote work, healthcare, hospitality, retail, social services, utilities and field service, where a worker may face violence, a medical emergency or an accident with nobody nearby to call for help.

Key Facts About Panic Buttons

  • A panic button is a manual alert; a man down alarm is automatic and triggers on a fall or lack of movement. Many devices combine both.
  • Silent or covert modes let a worker raise an alarm without escalating a confrontation.
  • An alarm only protects workers if someone is monitoring it 24/7 and knows exactly what to do.
  • Several U.S. states, including New Jersey, Illinois and Washington, require panic buttons for hotel housekeepers and other workers who work alone in guest rooms.
  • Location accuracy drops indoors and in remote areas without cell coverage, so device choice should match the work environment.

Example of a Panic Button in Use

A home healthcare nurse visiting a patient alone is confronted by an aggressive family member. She discreetly presses the SOS button in her lone worker app. The monitoring team sees her location, hears the situation through an open audio line, calls police and notifies her supervisor, following the agency's alert escalation plan.

How to Implement a Panic Button Program

  1. Identify roles with lone work, violence or remote-location risk through a hazard assessment.
  2. Choose devices or apps that suit the environment, such as satellite coverage for remote sites.
  3. Define who monitors alerts and the escalation steps for each alert type.
  4. Train workers on when and how to use the button, including silent activation.
  5. Test devices and the response chain regularly, and review false alarms rather than punishing them.

Frequently Asked Questions: Panic Button

What is the difference between a panic button and a man down alarm?

A panic button requires the worker to press it. A man down alarm triggers automatically when a device detects a fall, impact or no movement, which matters when the worker is unconscious or unable to reach the button.

Who should respond to a panic button alert?

A trained monitor, either an in-house team or a professional monitoring center, should receive alerts around the clock and follow a written escalation procedure that includes contacting the worker, supervisors and emergency services.

Can a phone app replace a dedicated panic button?

Often, yes. Lone worker apps can provide SOS, check-ins and location tracking. Dedicated wearables or satellite devices are better where phones are impractical, coverage is poor or the worker needs one-touch, hands-free activation.
