Mine Safety Technical Services (MSTS) is the exclusive distributor of CSE SCSRs within eastern Australia.
Self-Contained Self-Rescuers (SCSR) are an oxygen generating emergency escape apparatus worn on a person or cached strategically throughout a mine or tunnel. SCSRs are donned when an environment becomes irrespirable as a result of fire, explosion, gas outburst or contamination. The user is delivered a nominal duration of breathable oxygen which is generated through an exothermic reaction between the moisture in the users breathe and the chemical potassium superoxide (KO2) which is contained within the SCSR, this reaction also scrubs carbon dioxide from the user’s breath. Durations vary depending on the application, most SCSR have a range of 30 minute (traditionally body-worn) and 60 minute (traditionally cached).

COMING SOON: SYB30 SCSR
The CSE SYB-30 is an oxygen SCSR designed to provide the user with life-sustaining oxygen while protecting from potentially harmful gases or toxins in the ambient air.

ASR SCSR
MSTS partner with industry leaders CSE, who manufacture the ASR SCSR. The ASR short for Australian Self Rescuer, is design registered for use in underground coal mines throughout NSW and Qld. The ASR delivers the user 45 minutes of oxygen as per its registration testing and due to its compact size vs long duration, the ASR holds a niche in the market, being able to be utilised as either body-worn or cached. Designed so that it can be carried every day or stored away for up to 10 years without maintenance. The ASR can be used in application such as, mining, tunnelling, industrial plants, underground utilities or confined space applications.

SR-D (ASR Training Unit)
The SR-D will help provide trainees with hands-on training and gain experience in opening, donning, and using our SCSRs. It can be used in training for the SRLD, ASR, or SR100A. The SR-D includes features such as an opening mechanism, mouthpiece and nose clamp to simulate the experience of using an SCSR. The SR-D is not an expectation trainer and does not simulate the warmth and breathing resistance that an SCSR may have near the end of its operating duration.
SR-D (ASR Training Unit) Additional Information
Realistic Donning
- Trainees become familiar with donning the SRLD, ASR, or SR100A
- Allows trainees to perform hands-on training until proficient at donning
- Trainee can feel the fit of the breathing hose, mouthpiece, nose clamp, and protective goggles
Reusable
- Durable construction means the SR-D will hold up to many training events
- Components can quickly be dismantled for disinfecting with available cleaner
CSE Support
- As with all CSE training products, the SR-D is supported by easy-to-follow instructions and the full support of the CSE team
Made in the USA
- Designed and manufactured at our facility in Export, PA
Supports Training On
- SRLD
- ASR
- SR100A
Training Type
- Donning training
- Not an expectation trainer (no heat or oxygen produced)

SR-T (ASR Training Unit)
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.
SR-T (ASR Training Unit) Additional Information
Realistic Training
- Produces oxygen just like a real SCSR
- Trainees can perform exercises in simulated training scenarios with the SR-T
