How long will the SCSR provide oxygen for the wearer in an emergency situation?

The self-contained self-rescuer (SCSR) is designed to provide a minimum of one hour of breathable oxygen for the wearer in an emergency situation. This duration is critical, as it allows miners trapped in hazardous conditions, such as smoke or toxic gases, the necessary time to navigate to safety or await rescue.

The SCSR functions by generating oxygen through a chemical reaction and is equipped to support individuals under duress, emphasizing the importance of proper training and usage in ensuring the safety of miners. Recognizing that the SCSR is built with specific operational limits ensures that miners understand its capabilities and can effectively plan their escape routes or conservation strategies during emergencies.
