Health and Safety Issues• Do not drink the product!


• Do not mop up spilled product with paper towels



• Do not pour neat product down the drain



• Do not pour neat product down the drain

• Avoid contact between neat product with aluminium, copper, galvanised & other steels

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


• Will not cause any wastage to any material it contacts


• Will not cause any wastage to any material it contacts

• It remains stable up to 95ºC – no breakdown in calorifiers

How do you use it?

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)



• 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

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

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

Quantity to add for system volumeSystem Volume Volume of SafeSol 3

to obtain 100ppm hydrogen peroxide

Bottles you require to purchase

200 litres 500ml 1

300 litres 1 litre 1

500 litres 1.5 litres 2

1000 litres 3 litres 3

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

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!

Whirlpool Baths

• Water Inventory – 50 litres

Whirlpool Baths


• Dose level 400ppm hydrogen peroxide

Whirlpool Baths


• Dose level 400ppm hydrogen peroxide

• Use ½ litre of SafeSol3

Mains Water Disinfection

SafeSol3 can be added in a number of different ways



1.By using a Pressure Sprayer to inject into a drain point




2.By Having an ejector fitted to a bypass to allow the product to be sucked into the line in proportion to flow




2.By Having an ejector fitted to a bypass to allow the product to be sucked into the line in proportion to flow

3.By removing a spool piece and by fitting a spool piece with a water meter and an injector

What are the other uses?

Here are some other applications:



1.Water Features

Fountains, waterfalls, sprays – application dose is 100ppm hydrogen peroxide. Maintain at 50ppm hydrogen peroxide
