General Description of Red Bag Solutions SSM Technology:

Bio-hazardous medical waste processed in the RBS’s SSM unit is sterilized to 106 log reduction that is documented
with the use of Geobacillus stearothermophilus spore vials. It uses the US Food & Drug Administration (FDA)
principle of “Equivalent minutes.” All cycles are processed for 30 equivalent minutes at 250°F (121°C). Since
sterilization can occur at 15 minutes RBS thus uses a “double kill” to help guarantee sterilization. This is possible
because all processed waste in cut into small particles that are completely surrounded by superheated water and
steam, assuring all contents are sterilized equally. Liquid containers are broken open, completely cut up and the
liquid contents dumped into the superheated water and steam.

(a) principles of operation: Steam sterilization
(b) treatment capacity: 75 to 120 pounds (34 t0 54 kg) per 30 minute cycle
(c) dimensions: 10 feet long (305 cm), 4 feet wide (122 cm), 7 feet tall (213cm)
(d) time of the process: Each cycle is approximately 30 minutes
(e) operating conditions: In an environmentally controlled atmosphere: Room Temperature 40oF (4.5oC) to 100oF (37.8oC)
(f) Requirements for installation are water, sewer drainage, electricity, compressed air and data connection.


SSM-SI operates with steam supplied by the facility Steam supply must conform to specifications detailed in RBS SSM Installation Specification Guidelines.

It is important to know that the Red Bag SSM technology, although it uses steam sterilization, it does not operate
as an autoclave as it does not draw a vacuum. Thus, the correlation between temperature and pressure are not
the same as in an autoclave. Because it is a closed system the pressure in the tank during sterilization can range
between 30 to 50 psig or more.
