How long should your stored SCSR provide breathable air?

Explanation:
Stored SCSR is designed to provide breathable air for about an hour. That duration gives enough time to move to fresh air or reach a safe refuge during an underground emergency, even if you're not moving at full sprint but maintaining a steady pace. The device relies on a chemical reaction to generate breathable air, so it’s made to last for that typical escape period under normal exertion. In real use, the actual time can vary with how hard you’re working and how well the unit is maintained, but the standard rating is around an hour.
