Technology of microbiological protection of clean premises with Abris materials

The technology is intended for installation of mounting joints of units of window, door blocks adjoining wall openings with Abris materials in order to reduce the content of pathogenic microflora of the air medium to meet the requirements of GOST R ISO14644-1-2002 "Clean room and associated controlled media."

Technology Benefits

Significantly increases the microbiological security of clean premises by eliminating the causes of the arrival, release and retention of contaminants in the adjoining area of ? ? window, door blocks, which favorably affects:

improving the quality of the treatment process, caring for patients with diseases of the immune system;
hematopoietic systems and oncology;
reduction of in-hospital infections;
reduced postoperative complications and mortality.

Characteristics of hazardous factors

№	Characteristic defects of the mounting seams.	Consequences of mounting seam defects.
№	Characteristic defects of the mounting seams.	Physical and mechanical properties	l microbiological
1	Purging of the mounting seam	Intake of polluted outdoor air into a clean room; Retention of dirt in the materials of the inner layer of the mounting seam.	Reproduction of opportunistic microflora; Formation of pathogenic staphylococcus
2	Freezing of the mounting seam	Formation of dampness on the internal slopes of the window block, destruction of the materials of the mounting seam and finishing of the slopes	Formation of mold on the internal surfaces of building structures; Release of waste products of mold fungi into indoor air.

Results of microflora studies in the area of window blocks adjoining before carrying out sanitary treatment in a medical institution:

№	Study Name	*Number of norm exceedances ,%**
№	Study Name	When operating the old structure	After installation by Abris technology
1	Microflora content	64	0	Pathogenic microflora, the presence of columnar particles
2	Presence of pathogenic staphylococcus	18	0	Staphylococcus aureus. Staphylococcus haemolyticus
3	Presence of mold fungi	27	0	Alternaria spp, penicilliun spp, Aspergillus spp.
4	Washouts	17	0	Escherichia coli, citrobacter coli, enterobacter

Note: * norm according to GOST R ISO 14644-1-2002 "Clean room and associated controlled environments"

Materials used:
