The SR-T is a 15-minute expectation training device for all CSE SCSRs. It will help trainees get used to the breathing resistance and heat they would feel when using a real SCSR. The SR-T provides a realistic experience by producing oxygen the same way a CSE SCSR would, and it allows trainees to move and practice in simulated exercises. It also provides an opportunity to practice the Manual Start procedure. Over 96% of training participants who were surveyed said the SR-T provided a positive training experience.
