Last updated: July 12, 2019

What Does Alarm System Mean?

In a business context, an alarm system alerts employees about serious matters at work that may affect their safety.

The OSHA employee alarm system standard is applicable to all work situations that require an alarm safety system in order to satisfy an OSHA regulation.

Safeopedia Explains Alarm System

The two most common types of alarm used in the workplace are audible alarms and visual alarms. An audible alarm may take the form of a bell, siren, horn, or voice announcement. A visual alarm may use a steady strobe or flash light.

In order to meet OSHA specifications, an employee alarm must be able to be heard and seen above ambient noise and light levels by all employees in the workplace. Employees who are not able to see or hear a standard alarm should be catered for by way of a tactile alarm.

According to NFPA72 National Fire Alarm Code, new systems are not permitted to use bells, horns, or sirens. They can only be in the form of temporal or voice signals.
