What is the purpose of the heads-up display (HUD) in an SCBA?

The heads-up display (HUD) in an SCBA serves to provide visual information about the status of critical system functions. It is designed to be easily viewed by the wearer without the need to look away from their surroundings, allowing for increased situational awareness during operations. The HUD typically provides real-time data such as the remaining air supply, alerts, and other essential information, helping to ensure the safety and efficiency of the user in hazardous environments.

Using a heads-up display allows firefighters and emergency responders to quickly assess their situation and make informed decisions based on the information presented. This feature enhances operational effectiveness and safety by keeping the most vital data in the user's field of vision.
