What is the correct way to activate oxygen on the SCSR 100?

To activate oxygen on the SCSR 100, the process involves pulling the orange tag straight down. This action is designed to initiate the release of oxygen safely and effectively, allowing the user to begin breathing the oxygen supplied by the device. The mechanism is built to be straightforward so that in an emergency situation, users can quickly and intuitively activate the oxygen supply without confusion.

Other methods mentioned, such as twisting the cap, lifting the handle, or pressing a red button, do not correspond to the designed activation procedure for this specific device. Each of those alternatives may either be non-functional or pertain to different functions of the equipment, which could lead to improper usage in critical situations. Hence, pulling the orange tag straight down is the only correct action to ensure the SCSR 100 operates as intended to provide the necessary oxygen supply.
