What is the pressure of a fully charged oxygen canister in a BG4?

The pressure of a fully charged oxygen canister in a BG4 breathing apparatus is typically set at 200 bar. This level of pressure is necessary to ensure an adequate supply of oxygen during emergency situations in a mine rescue operation. The BG4 system is designed for use in environments where breathable air is not available, hence the importance of this specific pressure for maintaining safety and performance standards.

In the context of mine rescue operations, it is crucial for rescuers to have equipment that provides reliable and sufficient oxygen supply. The 200 bar pressure designation allows for a balance between volume and safety, enabling a prolonged duration of use while minimizing the risk of depletion too quickly. Understanding this specification is vital for anyone involved in mine safety or rescue training, as it directly relates to managing the lifesaving capabilities of the equipment used in emergencies.
