Voice Evacuation is a critically important technique used by businesses to ensure the safety of employees, customers and any other individuals present in a building during an emergency. It involves making announcements over the intercom or loudspeaker system to alert people about the urgency of a particular event and instruct them on the necessary steps they need to take. Voice Evacuation can also be utilized as part of an integrated evacuation system that takes into account multiple aspects such as lighting, signage, fire/smoke detection, and access to exits. By combining these different elements, businesses are able to help ensure their occupants are safely evacuated in the event of an emergency.
