What is the purpose of the indicator gauge on an emergency oxygen system?

The primary purpose of the indicator gauge on an emergency oxygen system is to indicate the amount of oxygen in the tank. This gauge is essential for ensuring that users can monitor the remaining supply of oxygen available for use during emergencies. By providing a clear visual representation of the oxygen levels, the gauge helps users make informed decisions about when to refill the tank or when to utilize the oxygen supply, thus enhancing safety and preparedness in emergency situations.

It's important to have accurate information about the oxygen supply because running out of oxygen during an emergency can be life-threatening. Therefore, the gauge plays a critical role in emergency response protocols. Proper monitoring allows individuals or rescue teams to manage their resources effectively and ensure that necessary actions can be taken well ahead of time.
