What is the purpose of the leak testing for the RZ 7000?

The purpose of leak testing for the RZ 7000 is to verify pressure integrity. In a mine rescue context, it is essential that any equipment, particularly those involved in breathing apparatus or other safety systems, maintains its structure and does not allow the escape of pressured gases. This testing ensures that the device can maintain the necessary pressure levels, which is critical for the safety of the user in an oxygen-deficient or hazardous environment.

Maintaining pressure integrity means that the system works as intended, delivering the necessary air or oxygen without leakage, thus ensuring that the person using the equipment has a reliable source of breathable air. This reliability is crucial in emergencies where delays or failures could have dire consequences. Other options, such as ensuring battery efficiency or checking compatibility with oxygen, do not specifically address the primary function of leak testing. Likewise, while confirming user safety is important, it encompasses a broader range of checks beyond just leak integrity.
