MSA SCBA SSR 30/100 Oxygen Self Rescuer

Safe Oxygen Supply for Various Applications

The oxygen self-rescuers SSR 30/100 and SSR 30/100 B are small, robust respiratory protective devices for self-rescue, which can be used at every place where the ambient atmosphere may be oxygen deficient or contain toxic contaminants. These devices employ the well-known and worldwide proven principle of generating oxygen chemically.

Due to its compact design and low weight, the oxygen self-rescuer can be worn continuously on the belt (SSR 30/100) or on the chest (SSR 30/100 B), so that it is available immediately in an emergency situation.

It is donned in seconds and supplies oxygen to the wearer on his escape or while waiting for rescue. The SSR 30/100 B is made for areas with the potential of abrupt eruptions of toxic gases or oxygen deficiency, requiring immediate breathing protection and fastest possible starting of the self-rescuer.

Design and functioning:

Both SSR 30/100 versions are housed in a stainless steel case which protects the self-rescuer very well under the rough conditions which such devices usually undergo that are carried along continuously. The case is air tight and under seal. In case of an emergency it can be opened simply and quickly.

The schematic shows the design and the air flow. The canister contains the chemical KO2 which reacts with the exhalation air. The humidity and carbon dioxide of the exhalation air cause a chemical reaction of the KO2, whereby carbon dioxide is retained and oxygen is released into the breathing bag.

The service time of the apparatus depends on the user’s work rate, respectively, breathing rate. Under heavy load and resultant high breathing rate more oxygen is generated than under slow and shallow breathing as, for instance, while waiting for rescue. Both SSR 30/100 versions have no pressurised components and are almost maintenance free. For used but complete and undamaged apparatus MSA offers economic reconditioning.

Donning the apparatus and breathing can be practiced with the SSR 30/100 TR training device.
