1 Disinfectant Designed for the 21 st Century

2 What is it?

3 3% Hydrogen Peroxide 19ppm silver Trace stabilisers Demineralised Water

4 Does it Work?

5 Efficacy?  Fast Legionella Bactericide – prEN13623 (’99)

6 Does it Work? Efficacy?  Fast Legionella Bactericide – prEN13623 (’99)  Kills the Trojan Horses – Rennes test

7 Does it Work? Efficacy?  Fast Legionella Bactericide – prEN13623 (’99)  Kills the Trojan Horses – Rennes test  Effectively removes and destroys biofilm -VITO/PIDPA tests

8 How it Works

9 Silver is attracted to cell wall of bacteria weakening the cell wall Ag+ Electrostatic attraction between bacteria and AG +

10 Ag+ Ooh-Ooh- OOH- Bacteria emit catalase cloud which blocks peroxide attack

11 Ag+ Ooh-Ooh- OOH- Silver destroys catalase

12 Ag+ Ooh-Ooh- OOH- Allowing OOH to breach the cell wall and kill the bacterium

13 The solution restabilises after attack WHEN ATTACK IS COMPLETE THE PEROXIDE IS ATTRACTED BACK BY SILVER STABILISING SOLUTION Ag+ OOH- RIP

14 Biofilm Removal  Chemical and physical cleaning

15 Biofilm Removal  Chemical and physical cleaning  Strong oxidation of bacteria coupled with effervescence on pipe wall

16 Biofilm Removal  Chemical and physical cleaning  Strong oxidation of bacteria coupled with effervescence on pipe wall  Hydrogen peroxide is a better disinfectant by 16 times when silver is present

17 1. Clean water distribution system 2. Attachment of bacteria (sec - min) 3. Growth and division of bacteria (hrs - days) 4. Expolymer production & Biofilm formation (hrs – days)

18 5. Attachment of other organisms to biofilm (days - months) Disappears into biofilm Into biofilm

30 Is perfectly safe in every respect at use concentration (100ppm hydrogen peroxide)

31 Will not cause any wastage to any material it contacts

32 Is perfectly safe in every respect at use concentration (100ppm hydrogen peroxide) Will not cause any wastage to any material it contacts It remains stable up to 95ºC – no breakdown in calorifiers

33 How do you use it?

34 Chemical should be added to water in the water storage tank following period of heavy use – after early morning baths in a nursing home

35 How do you use it? Chemical should be added to water in the water storage tank following period of heavy use – after early morning baths in a nursing home Calculate the volume of the system from tank volume X 1.3 (1.1 if no calorifier)

36 How do you use it? Chemical should be added to water in the water storage tank following period of heavy use – after early morning baths in a nursing home Calculate the volume of the system from tank volume X 1.3 (1.1 if no calorifier) Add quantity of SafeSol3 indicated in Ready Reckoner

37 How do you use it? Pull chemical to furthest hot and cold tap – check level and then check presence of chemical at each outlet using SafeSol test strip

38 How do you use it? Pull chemical to furthest hot and cold tap – check level and then check presence of chemical at each outlet using SafeSol test strip When the correct level is observed at each tap, leave site. The disinfection will be complete 24 hours later assuming normal water use

39 Quantity to add for system volume System VolumeVolume of SafeSol 3 to obtain 100ppm hydrogen peroxide Bottles you require to purchase 200 litres500ml1 300 litres1 litre1 500 litres1.5 litres litres 3 litres3

40 Quantity to add for system volume The hydrogen peroxide level should always be above 100ppm but below 125ppm to satisfy the DWI requirements - Test using test strips

41 Quantity to add for system volume The hydrogen peroxide level should always be above 100ppm but below 125ppm to satisfy the DWI requirements - Test using test strips If too high, run water out of the system via the outlets - if too low add more chemical Over fussiness costs time!

42 Whirlpool Baths Water Inventory – 50 litres
