When attaching the regulator to the facepiece, where should the red purge valve be pointing?

When attaching the regulator to the facepiece, the red purge valve should be pointing upwards. This orientation is crucial because it ensures the proper functioning of the purge valve, allowing for effective operation and ease of use in emergency situations. Having the valve facing up minimizes the risk of obstruction and allows for quick access to the purge feature if needed.

In contrast, positioning the valve in other directions may lead to complications, such as potential blockage when deploying the facepiece or making it harder to operate the purge function effectively during a critical moment. The upward positioning aligns with the design and operational protocols of the equipment, thereby enhancing safety and efficiency for the user in challenging environments.
