1 Cleaning of Hospital Floors How the Choice of Surfaces can Influence Maintenance Costs on Long Term? Congress Future Hospital th anniversary - 15./ in Helsinki Martin Duske nora systems GmbH, Weinheim

2 Cleaning of Hospital Floors - A Cost Trap? Over a life time of 15 years cleaning and maintenance costs of the floors make about % of the total costs of the floor Regular cleaning alone only makes 50% of these costs The remaining costs are made up by costs for coatings repair of surface protections (PU etc.) downtime costs 2

3 Life Cycle Calculation Floorcoverings 1500 m² Total ownership costs over 15 years 400 Values in Thousand Euro Renewal of surface or repair Regular maintenance 0 Lino acryl Lino PU PVC PU Investment 3

Maintenance according to needs Methods of regular maintenance are set up according to the needs of the hospital, not according to the floors Disinfection programs

4 Maintenance according to needs Methods of regular maintenance are set up according to the needs of the hospital, not according to the floors Disinfection programs Specific for rooms such as entry areas, corridors, wards, treatment rooms, OR s, Intensive Care, Sterilisation Units, etc.) Type and intensity of soiling Frequency 4

5 Regular Stripping and Coating PVC and Linoleum require regular stripping and coating Typical disadvantages: path forming yellowing of the coating problems with the elimination of the coating (chemical load) Advantage: Easy regular cleaning 5

9 Typical Damage with Linoleum Linoleum with UV-hardened PU surface protection Usable life 3-5 years according to intensity of use Sensitive to scratches and sensitive to mechanical charges 9

10 Limited Life time of Surface Finishes Linoleum Surface Finish Requires regular maintenance and renewal Regular re-coating and stripping with aggressive cleaning chemicals 10

11 Limited Life Time of Coating Rubber floor with PU coating Delaminates from the surface after exposure to UV light Requires cost-intensive repair measures 11

12 White Stains on Coatings Hand disinfectants may cause white stains on coatings Many coatings do not resist against alcohol 12

16 Long-term use of nora rubber floor in LKH Linz Report about the combined Manual and machine cleaning with diamond pads over 10 months on 3550 m²: noraplan With respect to the whole area in building H2/H3, we have managed, by combining machine and manual cleaning, to reduce the use of cleaning chemicals by about 50% in total. reduce the use of cleaning chemicals by about 50 % in total 16

17 reduce the use of cleaning chemicals by about 50 % in total 17

18 The Cleaning System with special Diamond Pads Condition: The floorcovering has to have a dense, closed and staple surface that is not covered by any additional coating => long serviceable lifetime Cross-section noraplan (without coating) Cleaning pads especially adapted for nora rubber floors 18

27 Chances and Limits of the Diamond Pad Cleaning Systems Advantages: Disadvantages: Fast and efficient work, no downtimes as areas don t need to be closed Little use of cleaning chemicals, thus cost efficient Improves slip resistance Machine cleaning required Increased gloss level 27

28 Chances and Limits of the Diamond Pad Cleaning Systems Important: Only pads that are approved by the manufacturer may be used, otherwise damages are possible Method may only be used on suitable floors, not on coated or PUR- protected floor surfaces! The use of diamond pads has proven to be most efficient for deep cleaning, stain removal and refurbishment of old floors For permanent maintenance in hospitals a combination of manual cleaning (using neutral cleaners and disinfection if necessary) and machine cleaning appears best suitable 28

29 Parameter for Planning of Floors: So far, surface characteristics of floors are hardly considered in planning Cleaning and maintenance costs are often accepted as given and not questionable Dependance of cleaning measures of the surface characteristics of the floors Cleaning industry takes profit of the short life-time of the surfaces to sell expensive repair products 29

30 Recommendations for planners and decision makers Analyse precisely the needs and the selection criteria Test the material previously for stain resistance, cleanability and longterm behavior Trial installations under practical conditions, but also look at the longterm behavior! Describe the required criteria precisely in you tender specification! 30
